Delete Method

Applies To

OraDynaset Object

Description

Deletes the current row of the specified dynaset.

Usage

oradynaset.Delete
oradynaset.DbDelete

Remarks

A row must be current before you can use the Delete method; otherwise, an error occurs.

Note that after you call the Delete method on a given row in a dynaset in a global transaction (that is, once you issue a BeginTrans method), locks remain on the selected rows until you call a CommitTrans or Rollback method.

Any references to the deleted row produce an error. The deleted row, as well as the next and previous rows, remain current until database movement occurs (using the MoveFirst, MovePrevious, MoveNext, or MoveLast methods). Once movement occurs, you cannot make the deleted row current again.

You cannot restore deleted records except by using transactions.

Examples

This example demonstrates the use of the Delete method to remove records from a database. Copy and paste this code into the definition section of a form. Then, press F5.

Sub Form_Load ()
 
'Declare variables
Dim OraSession As OraSession 
Dim OraDatabase As OraDatabase 
Dim OraDynaset As OraDynaset 
 
'Create the OraSession Object.
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
 
'Create the OraDatabase Object by opening a connection to Oracle.
Set OraDatabase = OraSession.OpenDatabase("exampledb", "scott/tiger", 0&)
 
'Create the OraDynaset Object. Only select the employees in Department 10.
Set OraDynaset = OraDatabase.CreateDynaset("select * from emp where" & _
          "deptno=10", 0&)
 
 Do Until OraDynaset.EOF
   OraDynaset.Delete
   OraDynaset.MoveNext
 Loop
 MsgBox "All employees from department 10 removed."
 
End Sub
