Commit Method (OracleTransaction)
Commits the database transaction.
The following example creates a
OracleConnection and a
OracleTransaction. It also demonstrates how to use the
BeginTransaction,
Commit, and
Rollback methods.
public void RunOracleTransaction(string myConnString)
{
OracleConnection myConnection = new OracleConnection(myConnString);
myConnection.Open();
OracleCommand myCommand = new OracleCommand();
OracleTransaction myTrans;
// Start a local transaction
myTrans = myConnection.BeginTransaction();
// Assign transaction object for a pending local transaction
myCommand.Transaction = myTrans;
try
{
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')";
myCommand.ExecuteNonQuery();
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(60, 'PRODUCTION')";
myCommand.ExecuteNonQuery();
myTrans.Commit();
Console.WriteLine("Both records are written to database.");
}
catch(Exception e)
{
myTrans.Rollback();
Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
}
finally
{
myConnection.Close();
}
}
Public Sub RunOracleTransaction(myConnString As String)
Dim myConnection As New OracleConnection(myConnString)
myConnection.Open()
Dim myCommand As New OracleCommand()
Dim myTrans As OracleTransaction
' Start a local transaction
myTrans = myConnection.BeginTransaction()
' Assign transaction object for a pending local transaction
myCommand.Transaction = myTrans
Try
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(50, 'DEVELOPMENT')"
myCommand.ExecuteNonQuery()
myCommand.CommandText = "INSERT INTO Test.Dept(DeptNo, DName) Values(60, 'PRODUCTION')"
myCommand.ExecuteNonQuery()
myTrans.Commit()
Console.WriteLine("Both records are written to database.")
Catch e As Exception
myTrans.Rollback()
Console.WriteLine(e.ToString())
Console.WriteLine("Neither record was written to database.")
Finally
myConnection.Close()
End Try
End Sub
