CommitTrans Method

Applies To

OraConnection Object

OraDatabase Object

OraSession Object

Description

Ends the current transaction and commits all pending changes to the database.

Usage

oraconnection.CommitTrans
oradatabase.CommitTrans
orasession.CommitTrans

Remarks

The CommitTrans method acts differently for these objects:

Note: If an OraDatabase object has been enlisted with Microsoft Transaction Server (MTS) and is part of a global MTS transaction, this method has no effect.

Examples

This example demonstrates the use of the BeginTrans method to group a set of dynaset edits into a single transaction. The CommitTrans method then accepts the changes. Copy 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 
 
 Dim fld As OraField
 
 '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.
 Set OraDynaset = OraDatabase.CreateDynaset("select * from emp", 0&)
 
 'Start Transaction processing.
 OraSession.BeginTrans
 
 'Setup a field object to save object references.
 Set fld = OraDynaset.Fields("sal")
 
 'Traverse until EOF is reached, setting each employees salary to zero.
 Do Until OraDynaset.EOF = True
   OraDynaset.Edit
   fld.value = 0
   OraDynaset.Update
   OraDynaset.MoveNext
 Loop
 MsgBox "All salaries set to ZERO."
 
 'Currently, the changes have NOT been committed 
 'to the database.
 
 'End Transaction processing. Commit the changes to the database
 OraSession.CommitTrans
 MsgBox "Salary changes committed."
 
End Sub
