GRANT

Purpose

Use the GRANT statement to grant:

Roles to users and roles. The granted roles can be either user-defined (local or external) or predefined. For a list of predefined roles, refer to Oracle Database Security Guide.
System privileges to users and roles. Table 18-1 lists the system privileges (organized by the database object operated upon).
Object privileges for a particular object to users, roles, and PUBLIC. Table 18-2 lists object privileges (organized by the database object operated upon).

Note:

Global roles (created with IDENTIFIED GLOBALLY) are granted through enterprise roles and cannot be granted using the GRANT statement.

Notes on Authorizing Database Users You can authorize database users through means other than the database and the GRANT statement.

Many Oracle Database privileges are granted through supplied PL/SQL and Java packages. For information on those privileges, refer to the documentation for the appropriate package.
Some operating systems have facilities that let you grant roles to Oracle Database users with the initialization parameter OS_ROLES. If you choose to grant roles to users through operating system facilities, then you cannot also grant roles to users with the GRANT statement, although you can use the GRANT statement to grant system privileges to users and system privileges and roles to other roles.

Note on Oracle Automatic Storage Management A user authenticated AS SYSASM can use this statement to grant the system privileges SYSASM, SYSOPER, and SYSDBA to a user in the Oracle ASM password file of the current node.

Note on Editionable Objects

A GRANT operation to grant object privileges on an editionable object actualizes the object in the current edition. See Oracle Database Advanced Application Developer's Guide for more information about editions and editionable objects.

Prerequisites

To grant a system privilege, one of the following conditions must be met:

You must have been granted the GRANT ANY PRIVILEGE system privilege. In this case, if you grant the system privilege to a role, then a user to whom the role has been granted does not have the privilege unless the role is enabled in user's session.
You must have been granted the system privilege with the ADMIN OPTION. In this case, if you grant the system privilege to a role, then a user to whom the role has been granted has the privilege regardless whether the role is enabled in the user's session.

To grant a role, you must either have been granted the role with the ADMIN OPTION or have been granted the GRANT ANY ROLE system privilege, or you must have created the role.

To grant an object privilege, you must own the object, or the owner of the object must have granted you the object privileges with the GRANT OPTION, or you must have been granted the GRANT ANY OBJECT PRIVILEGE system privilege. If you have the GRANT ANY OBJECT PRIVILEGE, then you can grant the object privilege only if the object owner could have granted the same object privilege. In this case, the GRANTOR column of the DBA_TAB_PRIVS view displays the object owner rather than the user who issued the GRANT statement.

Semantics

grant_system_privileges

Use these clauses to grant system privileges.

system_privilege

Specify the system privilege you want to grant. Table 18-1 lists the system privileges, organized by the database object operated upon.

If you grant a privilege to a user, then the database adds the privilege to the user's privilege domain. The user can immediately exercise the privilege. Oracle recommends that you only grant the ANY privileges to trusted users.
If you grant a privilege to a role, then the database adds the privilege to the privilege domain of the role. Users who have been granted and have enabled the role can immediately exercise the privilege. Other users who have been granted the role can enable the role and exercise the privilege.

See Also:
Granting a System Privilege to a User: Example and "Granting System Privileges to a Role: Example"
If you grant a privilege to PUBLIC, then the database adds the privilege to the privilege domains of each user. All users can immediately perform operations authorized by the privilege. Oracle recommends against granting system privileges to PUBLIC.

Oracle Database provides the ALL PRIVILEGES shortcut for granting all the system privileges listed in Table 18-1, except the SELECT ANY DICTIONARY, ALTER DATABASE LINK, and ALTER PUBLIC DATABASE LINK privileges.

role

Specify the role you want to grant. You can grant an Oracle Database predefined role or a user-defined role.

If you grant a role to a user, then the database makes the role available to the user. The user can immediately enable the role and exercise the privileges in the privilege domain of the role.

In the case of a secure application role, you need not grant such a role directly to the user. You can let the associated PL/SQL package do this, assuming the user passes appropriate security policies. For more information, see the CREATE ROLE semantics for USING package and Oracle Database Security Guide
If you grant a role to another role, then the database adds the privilege domain of the granted role to the privilege domain of the grantee role. Users who have been granted the grantee role can enable it and exercise the privileges in the granted role's privilege domain.
If you grant a role to PUBLIC, then the database makes the role available to all users. All users can immediately enable the role and exercise the privileges in the privilege domain of the role.

See Also:

Oracle Database Security Guide for information on the Oracle predefined roles
"Granting a Role to a Role: Example"
CREATE ROLE for information on creating a user-defined role

IDENTIFIED BY Clause

This clause is valid only when granting system privileges, not when granting object privileges. Use the IDENTIFIED BY clause to specify a new password for an existing user or to create a nonexistent user. This clause is not valid if the grantee is a role or PUBLIC. If the user specified in the grantee_clause does not exist, then the database creates the user with the password and with the privileges and roles specified in this clause.

See Also:

CREATE USER for restrictions on usernames and passwords

WITH ADMIN OPTION

Specify WITH ADMIN OPTION to enable the grantee to:

Grant the privilege or role to another user or role, unless the role is a GLOBAL role
Revoke the privilege or role from another user or role
Alter the privilege or role to change the authorization needed to access it
Drop the privilege or role

If you grant a system privilege or role to a user without specifying WITH ADMIN OPTION, and then subsequently grant the privilege or role to the user WITH ADMIN OPTION, then the user has the ADMIN OPTION on the privilege or role.

To revoke the ADMIN OPTION on a system privilege or role from a user, you must revoke the privilege or role from the user altogether and then grant the privilege or role to the user without the ADMIN OPTION.

grantee_clause

TO grantee_clause identifies users or roles to which the system privilege, role, or object privilege is granted.

Restriction on Grantees A user, role, or PUBLIC cannot appear more than once in TO grantee_clause.

PUBLIC

Specify PUBLIC to grant the privileges to all users. Oracle recommends against granting system privileges to PUBLIC.

Restrictions on Granting System Privileges and Roles Privileges and roles are subject to the following restrictions:

A privilege or role cannot appear more than once in the list of privileges and roles to be granted.
You cannot grant a role to itself.
You cannot grant a role IDENTIFIED GLOBALLY to anything.
You cannot grant a role IDENTIFIED EXTERNALLY to a global user or global role.
You cannot grant roles circularly. For example, if you grant the role banker to the role teller, then you cannot subsequently grant teller to banker.

grant_object_privileges

Use these clauses to grant object privileges.

object_privilege

Specify the object privilege you want to grant. Table 18-2 lists the object privileges, organized by the type of object on which they can be granted. When you grant an object privilege on a editionable object, either to a user or to a role, the object is actualized in the edition in which the grant is made. Refer to CREATE EDITION for information on editionable object types and editions.

Note:

To grant SELECT on a view to another user, either you must own all of the objects underlying the view or you must have been granted the SELECT object privilege WITH GRANT OPTION on all of those underlying objects. This is true even if the grantee already has SELECT privileges on those underlying objects.

Restriction on Object Privileges A privilege cannot appear more than once in the list of privileges to be granted.

ALL [PRIVILEGES]

Specify ALL to grant all the privileges for the object that you have been granted with the GRANT OPTION. The user who owns the schema containing an object automatically has all privileges on the object with the GRANT OPTION. The keyword PRIVILEGES is provided for semantic clarity and is optional.

column

Specify the table or view column on which privileges are to be granted. You can specify columns only when granting the INSERT, REFERENCES, or UPDATE privilege. If you do not list columns, then the grantee has the specified privilege on all columns in the table or view.

For information on existing column object grants, query the USER_, ALL_, or DBA_COL_PRIVS data dictionary view.

See Also:

Oracle Database Reference for information on the data dictionary views and "Granting Multiple Object Privileges on Individual Columns: Example"

on_object_clause

The on_object_clause identifies the object on which the privileges are granted. Directory schema objects, editions, data mining models, and Java source and resource schema objects are identified separately because they reside in separate namespaces.

If you can make this grant only because you have the GRANT ANY OBJECT PRIVILEGE system privilege—that is, you are not the owner of object, nor do you have object_privilege on object WITH GRANT OPTION—then the effect of this grant is that you are acting on behalf of the object owner. The *_TAB_PRIVS data dictionary views will reflect that this grant was made by the owner of object.

See Also:

"Granting Object Privileges to a Role: Example"
"Revoke Operations that Use GRANT ANY OBJECT PRIVILEGE: Example" for more information on using the GRANT ANY OBJECT PRIVILEGE system privilege for revoke operations

WITH GRANT OPTION

Specify WITH GRANT OPTION to enable the grantee to grant the object privileges to other users and roles.

If you grant an object privilege to a user without specifying WITH GRANT OPTION, and then subsequently grant the privilege to the user WITH GRANT OPTION, then the user has the GRANT OPTION on the privilege.

To revoke the GRANT OPTION on an object privilege from a user, you must revoke the privilege from the user altogether and then grant the privilege to the user without the GRANT OPTION.

Restriction on Granting WITH GRANT OPTION You can specify WITH GRANT OPTION only when granting to a user or to PUBLIC, not when granting to a role.

WITH HIERARCHY OPTION

Specify WITH HIERARCHY OPTION to grant the specified object privilege on all subobjects of object, such as subviews created under a view, including subobjects created subsequent to this statement.

This clause is meaningful only in combination with the SELECT object privilege.

object Specify the schema object on which the privileges are to be granted. If you do not qualify object with schema, then the database assumes the object is in your own schema. The object can be one of the following types:

Table, view, or materialized view
Sequence
Procedure, function, or package
User-defined type
Synonym for any of the preceding items
Directory, library, operator, or indextype
Java source, class, or resource

You cannot grant privileges directly to a single partition of a partitioned table.

DIRECTORY directory_name Specify a directory schema object on which privileges are to be granted. You cannot qualify directory_name with a schema name.

JAVA SOURCE | RESOURCE The JAVA clause lets you specify a Java source or resource schema object on which privileges are to be granted.

CREATE JAVA

Listings of System and Object Privileges

Note:

When you grant a privilege on ANY object, such as CREATE ANY CLUSTER, the result is determined by the value of the O7_DICTIONARY_ACCESSIBILITY initialization parameter. By default, this parameter is set to FALSE, so that ANY privileges give the grantee access to that type of object in all schemas except the SYS schema. If you set O7_DICTIONARY_ACCESSIBILITY to TRUE, then the ANY privileges also give the grantee access, in the SYS schema, to all objects except Oracle Scheduler objects. For security reasons, Oracle recommends that you use this setting only with great caution.

See also Oracle Database Reference for information on the `OPTIMIZER_SECURE_VIEW_MERGING` parameter and Oracle Database Performance Tuning Guide for information on view merging.
MISCELLANEOUS:	—
`ANALYZE ANY`	Analyze any table, cluster, or index in any schema.

Allows Streams administrators to create or alter capture users and apply users in a Streams environment. By default this privilege is part of the DBA role. Database Vault removes this privileges from the DBA role. Therefore, this privilege is needed by Streams only in an environment where Database Vault is installed.
`CHANGE` `NOTIFICATION`	Create a registration on queries and receive database change notifications in response to DML or DDL changes to the objects associated with the registered queries. Refer to Oracle Database Advanced Application Developer's Guide for more information on database change notification.
`COMMENT ANY TABLE`	Comment on any table, view, or column in any schema.
`EXEMPT ACCESS POLICY`	Bypass fine-grained access control. Caution: This is a very powerful system privilege, as it lets the grantee bypass application-driven security policies. Database administrators should use caution when granting this privilege.

`GRANT ANY PRIVILEGE`	Grant any system privilege.
`RESUMABLE`	Enable resumable space allocation.
`SELECT ANY DICTIONARY`	Query any data dictionary object in the `SYS` schema. This privilege lets you selectively override the default `FALSE` setting of the `O7_DICTIONARY_ACCESSIBILITY` initialization parameter.
`SELECT ANY TRANSACTION`	Query the contents of the `FLASHBACK_TRANSACTION_QUERY` view. Caution: This is a very powerful system privilege, as it lets the grantee view all data in the database, including past data. This privilege should be granted only to users who need to use the Oracle Flashback Transaction Query feature.
`SYSDBA`	Perform `STARTUP` and `SHUTDOWN` operations. `ALTER` `DATABASE`: open, mount, back up, or change character set. `CREATE` `DATABASE`. `ARCHIVELOG` and `RECOVERY`. `CREATE` `SPFILE`. Includes the `RESTRICTED` `SESSION` privilege.
`SYSOPER`	Perform `STARTUP` and `SHUTDOWN` operations. `ALTER` `DATABASE`: open, mount, or back up. `ARCHIVELOG` and `RECOVERY`. `CREATE` `SPFILE`. Includes the `RESTRICTED` `SESSION` privilege.

Table 18-2 Object Privileges (Organized by the Database Object Operated Upon)

Object Privilege Name	Operations Authorized
DIRECTORY PRIVILEGES	The following directory privileges provide secured access to the files stored in the operating system directory to which the directory object serves as a pointer. The directory object contains the full path name of the operating system directory where the files reside. Because the files are actually stored outside the database, Oracle Database server processes also need to have appropriate file permissions on the file system server. Granting object privileges on the directory database object to individual database users, rather than on the operating system, allows the database to enforce security during file operations.
`READ`	Read files in the directory.
`WRITE`	Write files in the directory. This privilege is useful only in connection with external tables. It allows the grantee to determine whether the external table agent can write a log file or a bad file to the directory. Restriction: This privilege does not allow the grantee to write to a `BFILE`.
`EXECUTE`	Execute a preprocessor program that resides in the directory. A preprocessor program converts data to a supported format when loading data records from an external table with the `ORACLE_LOADER` access driver. Refer to Oracle Database Utilities for more information. This privilege does not implicitly allow READ access on the external table data.
EDITION PRIVILEGE	The following edition privilege authorizes the use of an edition.
`USE`	Use an edition.
INDEXTYPE PRIVILEGE	The following indextype privilege authorizes operations on indextypes.
`EXECUTE`	Reference an indextype.
FLASHBACK DATA ARCHIVE PRIVILEGE	The following flashback data archive privilege authorizes operations on flashback data archives.
`FLASHBACK ARCHIVE`	Enable or disable historical tracking for a table.
LIBRARY PRIVILEGE	The following library privilege authorizes operations on a library.
`EXECUTE`	Use and reference the specified object and invoke its methods. Caution: This extremely powerful privilege should be granted only to trusted users. Refer to Oracle Database Security Guide before granting this privilege.
MATERIALIZED VIEW PRIVILEGES	The following materialized view privileges authorize operations on a materialized view. The `DELETE`, `INSERT`, and `UPDATE` privileges can be granted only to updatable materialized views.
`ON COMMIT REFRESH`	Create a refresh-on-commit materialized view on the specified table.
`QUERY REWRITE`	Create a materialized view for query rewrite using the specified table.
`SELECT`	Query the materialized view with the `SELECT` statement.
MINING MODEL PRIVILEGES	The following mining model privileges authorize operations on a mining model. These privileges are not required for models within the users own schema.
`ALTER`	Change the mining model name or the associated cost matrix using the applicable `DBMS_DATA_MINING` procedures.
`SELECT`	Score or view the mining model. Scoring is done with the `PREDICTION` family of SQL functions or with the `DBMS_DATA_MINING.APPLY` procedure. Viewing the model is done with the `DBMS_DATA_MINING.GET_MODEL_DETAILS_*` procedures.
OBJECT TYPE PRIVILEGES	The following object type privileges authorize operations on a database object type.
`DEBUG`	Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object type. Place a breakpoint or stop at a line or instruction boundary within the type body.
`EXECUTE`	Use and reference the specified object and invoke its methods. Access, through a debugger, public variables, types, and methods defined on the object type.
`UNDER`	Create a subtype under this type. You can grant this object privilege only if you have the `UNDER` `ANY` `TYPE` privilege `WITH` `GRANT` `OPTION` on the immediate supertype of this type.
OLAP PRIVILEGES	The following object privileges are valid if you are using Oracle Database with the OLAP option.
`INSERT`	Insert members into the OLAP cube dimension or measures into the measures folder.
`ALTER`	Change the definition of the OLAP cube dimension or cube.
`DELETE`	Delete members from the OLAP cube dimension or measures from the measures folder.
`SELECT`	View or query the OLAP cube or cube dimension.
`UPDATE`	Update measure values of the OLAP cube or attribute values of the cube dimension.
OPERATOR PRIVILEGE	The following operator privilege authorizes operations on user-defined operators.
`EXECUTE`	Reference an operator.
PROCEDURE, FUNCTION, PACKAGE PRIVILEGES	The following procedure, function, and package privileges authorize operations on procedures, functions, and packages. These privileges also apply to Java sources, classes, and resources, which Oracle Database treats as though they were procedures for purposes of granting object privileges.
`DEBUG`	Access, through a debugger, all public and nonpublic variables, methods, and types defined on the object. Place a breakpoint or stop at a line or instruction boundary within the procedure, function, or package. This privilege grants access to the declarations in the method or package specification and body.
`EXECUTE`	Execute the procedure or function directly, or access any program object declared in the specification of a package, or compile the object implicitly during a call to a currently invalid or uncompiled function or procedure. This privilege does not allow the grantee to explicitly compile using `ALTER PROCEDURE` or `ALTER FUNCTION`. For explicit compilation you need the appropriate `ALTER` system privilege. Access, through a debugger, public variables, types, and methods defined on the procedure, function, or package. This privilege grants access to the declarations in the method or package specification only. Job scheduler objects are created using the `DBMS_SCHEDULER` package. After these objects are created, you can grant the `EXECUTE` object privilege on job scheduler classes and programs. You can also grant `ALTER` privilege on job scheduler jobs, programs, and schedules. Note: Users do not need this privilege to execute a procedure, function, or package indirectly.
SCHEDULER PRIVILEGES	Job scheduler objects are created using the `DBMS_SCHEDULER` package. After these objects are created, you can grant the following privileges.
`EXECUTE`	Operations on job classes, programs, chains, and credentials.
`ALTER`	Modifications to jobs, programs, chains, credentials, and schedules.
SEQUENCE PRIVILEGES	The following sequence privileges authorize operations on a sequence.
`ALTER`	Change the sequence definition with the `ALTER` `SEQUENCE` statement.
`SELECT`	Examine and increment values of the sequence with the `CURRVAL` and `NEXTVAL` pseudocolumns.
SYNONYM PRIVILEGES	Synonym privileges are the same as the privileges for the target object. Granting a privilege on a synonym is equivalent to granting the privilege on the base object. Similarly, granting a privilege on a base object is equivalent to granting the privilege on all synonyms for the object. If you grant to a user a privilege on a synonym, then the user can use either the synonym name or the base object name in the SQL statement that exercises the privilege.
TABLE PRIVILEGES	The following table privileges authorize operations on a table. Any one of following object privileges allows the grantee to lock the table in any lock mode with the `LOCK` `TABLE` statement. Note: For external tables, the only valid object privileges are `ALTER` and `SELECT`.
`ALTER`	Change the table definition with the `ALTER` `TABLE` statement.
`DEBUG`	Access, through a debugger: PL/SQL code in the body of any triggers defined on the table Information on SQL statements that reference the table directly
`DELETE`	Remove rows from the table with the `DELETE` statement. Note: You must grant the `SELECT` privilege on the table along with the `DELETE` privilege if the table is on a remote database.
`INDEX`	Create an index on the table with the `CREATE` `INDEX` statement.
`INSERT`	Add new rows to the table with the `INSERT` statement. Note: You must grant the `SELECT` privilege on the table along with the `INSERT` privilege if the table is on a remote database.
`REFERENCES`	Create a constraint that refers to the table. You cannot grant this privilege to a role.
`SELECT`	Query the table with the `SELECT` statement.
`UPDATE`	Change data in the table with the `UPDATE` statement. Note: You must grant the `SELECT` privilege on the table along with the `UPDATE` privilege if the table is on a remote database.
VIEW PRIVILEGES	The following view privileges authorize operations on a view. Any one of the following object privileges allows the grantee to lock the view in any lock mode with the `LOCK` `TABLE` statement. To grant a privilege on a view, you must have that privilege with the `GRANT` `OPTION` on all of the base tables of the view.
`DEBUG`	Access, through a debugger: PL/SQL code in the body of any triggers defined on the view Information on SQL statements that reference the view directly
`DELETE`	Remove rows from the view with the `DELETE` statement.
`INSERT`	Add new rows to the view with the `INSERT` statement.
`MERGE` `VIEW`	This object privilege has the same behavior as the system privilege `MERGE ANY VIEW`, except that the privilege is limited to the views specified in the `ON` clause. For any query issued by the grantee on the specified views, the optimizer can use view merging to improve query performance without performing the checks that would otherwise be performed to ensure that view merging does not violate any security intentions of the view creator.
`REFERENCES`	Define foreign key constraints on the view.
`SELECT`	Query the view with the `SELECT` statement. See Also: object_privilege for additional information on granting this object privilege on a view
`UNDER`	Create a subview under this view. You can grant this object privilege only if you have the `UNDER` `ANY` `VIEW` privilege `WITH` `GRANT` `OPTION` on the immediate superview of this view.
`UPDATE`	Change data in the view with the `UPDATE` statement.

Examples

Granting a System Privilege to a User: Example To grant the CREATE SESSION system privilege to the sample user hr, allowing hr to log on to Oracle Database, issue the following statement:

GRANT CREATE SESSION 
   TO hr;

Granting System Privileges to a Role: Example The following statement grants appropriate system privileges to a data warehouse manager role, which was created in the "Creating a Role: Example":

GRANT
     CREATE ANY MATERIALIZED VIEW
   , ALTER ANY MATERIALIZED VIEW
   , DROP ANY MATERIALIZED VIEW
   , QUERY REWRITE
   , GLOBAL QUERY REWRITE
   TO dw_manager
   WITH ADMIN OPTION;

The dw_manager privilege domain now contains the system privileges related to materialized views.

Granting a Role with the Admin Option: Example To grant the dw_manager role with the ADMIN OPTION to the sample user sh, issue the following statement:

GRANT dw_manager 
   TO sh 
   WITH ADMIN OPTION;

User sh can now perform the following operations with the dw_manager role:

Enable the role and exercise any privileges in the privilege domain of the role, including the CREATE MATERIALIZED VIEW system privilege
Grant and revoke the role to and from other users
Drop the role

Granting Object Privileges to a Role: Example The following example grants the SELECT object privileges to a data warehouse user role, which was created in the "Creating a Role: Example":

GRANT SELECT ON sh.sales TO warehouse_user;

Granting a Role to a Role: Example The following statement grants the warehouse_user role to the dw_manager role. Both roles were created in the "Creating a Role: Example":

GRANT warehouse_user TO dw_manager;

The dw_manager role now contains all of the privileges in the domain of the warehouse_user role.

Granting an Object Privilege on a Directory: Example To grant READ on directory bfile_dir to user hr, with the GRANT OPTION, issue the following statement:

GRANT READ ON DIRECTORY bfile_dir TO hr
   WITH GRANT OPTION;

Granting Object Privileges on a Table to a User: Example To grant all privileges on the table oe.bonuses, which was created in "Merging into a Table: Example", to the user hr with the GRANT OPTION, issue the following statement:

GRANT ALL ON bonuses TO hr 
   WITH GRANT OPTION;

The user hr can subsequently perform the following operations:

Exercise any privilege on the bonuses table
Grant any privilege on the bonuses table to another user or role

Granting Object Privileges on a View: Example To grant SELECT and UPDATE privileges on the view emp_view, which was created in "Creating a View: Example", to all users, issue the following statement:

GRANT SELECT, UPDATE 
   ON emp_view TO PUBLIC;

All users can subsequently query and update the view of employee details.

Granting Object Privileges to a Sequence in Another Schema: Example To grant SELECT privilege on the customers_seq sequence in the schema oe to the user hr, issue the following statement:

GRANT SELECT 
   ON oe.customers_seq TO hr;

The user hr can subsequently generate the next value of the sequence with the following statement:

SELECT oe.customers_seq.NEXTVAL 
   FROM DUAL;

Granting Multiple Object Privileges on Individual Columns: Example To grant to user oe the REFERENCES privilege on the employee_id column and the UPDATE privilege on the employee_id, salary, and commission_pct columns of the employees table in the schema hr, issue the following statement:

GRANT REFERENCES (employee_id), 
      UPDATE (employee_id, salary, commission_pct) 
   ON hr.employees
   TO oe;

The user oe can subsequently update values of the employee_id, salary, and commission_pct columns. User oe can also define referential integrity constraints that refer to the employee_id column. However, because the GRANT statement lists only these columns, oe cannot perform operations on any of the other columns of the employees table.

For example, oe can create a table with a constraint:

CREATE TABLE dependent 
   (dependno   NUMBER, 
    dependname VARCHAR2(10), 
    employee   NUMBER 
   CONSTRAINT in_emp REFERENCES hr.employees(employee_id) );

The constraint in_emp ensures that all dependents in the dependent table correspond to an employee in the employees table in the schema hr.
