If the AutoCommit property is set to True, all the data operations that modify data in the database are automatically committed after the statement is executed.
If the AutoCommit property is set to False, you need to use the OraDatabase transaction methods (BeginTrans, CommitTrans, and Rollback) or SQL statements to control transactions.
The following example shows how to control transactions with SQL statements after setting the AutoCommit property to False.
Dim session As OraSession
Dim MyDb As OraDatabase
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
Set MyDb = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0)
MyDb.AutoCommit = False
MyDb.ExecuteSQL ("update emp set sal = 100000" & _
"where ename = 'JOHN SMITH' ")
MyDb.ExecuteSQL ("commit")
