This section provides information on how to use SQL Scripts to create, edit, view, run, and delete script files.
This section contains the following topics:
A SQL script is a set of SQL commands saved as a file in SQL Scripts. A SQL script can contain one or more SQL statements or PL/SQL blocks. You can use SQL Scripts to create, edit, view, run, and delete script files.
When using SQL Scripts, remember the following:
SQL*Plus commands in a SQL script are ignored at run time.
There is no interaction between SQL Commands and SQL Scripts.
You can cut and paste a SQL command from the SQL Script editor to run it in SQL Commands.
SQL Scripts does not support bind variables.
To access SQL Scripts:
Log in to the Workspace home page.
To view SQL Scripts page you can either:
Click the SQL Workshop icon and then SQL Scripts to drill-down to the SQL Scripts page.
Click the down arrow on the right side of the SQL Workshop icon to view a drop down menu. Then select the SQL Scripts menu option.
Note:
For the purposes of consistency, this document uses the primary navigation path (or drill-down approach) when explaining navigation.The SQL Scripts page display all SQL scripts created by the current user. You can control the appearance of the page by making a selection from the View list. The default view, Icons, displays each script as an icon. Details view displays each script as a row in a report.
The SQL Scripts page features the following controls:
Script. Search for a script by entering the script name, or a partial name, in the Script field and clicking Go. You control how many rows display by making a selection from the Display list.
Owner. Search for the owner of the script you want to view by entering the user name in the Owner field and clicking Go.
View. Change the appearance of the SQL Scripts page by making a selection from the View list and clicking Go. Available View options include:
Icons (default) displays each script as an icon identified by the script name. Click the Show Results check box to additionally display run results as icons identified by the script name.
Details displays each script as a line in a report. Each line includes a check box to enable the selection of scripts for deletion, an edit icon to enable the script to be loaded into the script editor, the script name, the script owner, when the script was last updated and by who, the size in bytes, the number of times the script has been run linked to the run results, and an icon to enable the script to be run.
Details view offers the following additional controls:
Delete Checked. In Details view, select the check box associated with the script you want to delete and click Delete Checked. See "Deleting a SQL Script".
Sort. In Details view, click a column heading to sort the listed scripts by that column.
Upload. Click Upload to upload a script from your local file system into SQL Scripts. See "Creating a SQL Script".
Create. Click Create to create a script in the Script Editor. See "Creating a SQL Script".
Switching to Another SQL Workshop Component
You can navigate to another SQL Workshop component by making a selection from the Component list located on the upper right side of the page:
Object Browser. See "Managing Database Objects with Object Browser".
SQL Commands. See "Using SQL Commands".
SQL Scripts. See "Using SQL Scripts".
Query Builder. See "Building Queries with Query Builder".
A Tasks list displays on the right side of the SQL Scripts page.
The Task list contains the following links:
Manage Results enables you to view, search, and display results. See "Viewing SQL Script Results".
Show Quotas displays the Script Quotas page. The Script Quotas page shows the maximum size of a single result, the maximum size of all results, the quota used and the quota free. It also shows the maximum size of a SQL Script.
Export enables you to export multiple scripts from the current SQL Script Repository for import into SQL Scripts in a different workspace. The scripts you select to export are encoded in a single export script written to your local file system. The export script is named workspace_name_script.sql by default. See "Exporting and Importing SQL Scripts".
Import enables you to import a script exported by this workspace, or a different workspace. Import only imports scripts encoded in an export script created using Export. The export script to import must be accessible on your local file system. See "Exporting and Importing SQL Scripts".

There are two panes on the Export SQL Scripts page, the Scripts pane and the Scripts to Export pane. You use the Scripts pane to select scripts to export. Then, you use the Scripts to Export pane to finalize the scripts to export, to choose a name for the export script, and to save the selected scripts in the export script on your local file system. You use the Import Scripts pane to select the export script containing the scripts to import.
