Property Value

The SqlCeTransaction. The default value is a null reference (Nothing in Visual Basic).

You cannot set the Transaction property if it is already set to a specific value and the command is in the process of executing. If you set the transaction property of a SqlCeTransaction object that is not connected to the same SqlCeConnection as the SqlCeCommand object, an exception will be thrown the next time you execute a statement.

If SqlCeCommand runs with SqlCeTransaction set to a null reference (Nothing in Visual Basic), the command runs in autocommit mode; therefore, each statement runs in its own transaction.

SqlCeConnection conn = new SqlCeConnection("Data Source = MyDatabase.sdf; Password ='<pwd>'");

// Start a local transaction
SqlCeTransaction tx = conn.BeginTransaction();

// By default, commands run in auto-commit mode; 
SqlCeCommand cmd1 = conn.CreateCommand();

// You may create multiple commands on the same connection
SqlCeCommand cmd2 = conn.CreateCommand();

// To enlist a command in a transaction, set the Transaction property
cmd1.Transaction = tx;

    cmd1.CommandText = "INSERT INTO Shippers ([Company Name]) VALUES ('Northwind Traders')";

    // Auto-commited because cmd2 is not enlisted in a transaction
    cmd2.CommandText = "INSERT INTO Employees ([Last Name], [First Name]) VALUES ('Nancy', 'Smith')";

    // This will cause referential constraint violation
    cmd1.CommandText = "DELETE FROM Products WHERE [Product ID] = 1";

    // Commit the changes to disk if everything above succeeded
catch (Exception)
