Commit Method (UniConnection)
Commits the database transaction.
The following example demonstrates how to use
Commit and
Rollback methods.
public void RunUniTransaction(string myConnString)
{
UniConnection myConnection = new UniConnection(myConnString);
myConnection.Open();
UniCommand myCommand = new UniCommand();
myCommand.Connection = myConnection;
myConnection.BeginTransaction();
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();
myConnection.Commit();
Console.WriteLine("Both records are written to database.");
}
catch(Exception e)
{
myConnection.Rollback();
Console.WriteLine(e.ToString());
Console.WriteLine("Neither record was written to database.");
}
finally
{
myConnection.Close();
}
}
Public Sub RunUniTransaction(myConnString As String)
Dim myConnection As New UniConnection(myConnString)
myConnection.Open()
Dim myCommand As New UniCommand()
myCommand.Connection = myConnection
myConnection.BeginTransaction()
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()
myConnection.Commit()
Console.WriteLine("Both records are written to database.")
Catch e As Exception
myConnection.Rollback()
Console.WriteLine(e.ToString())
Console.WriteLine("Neither record was written to database.")
Finally
myConnection.Close()
End Try
End Sub
