Using a SQL Statement to Create the CompositeCommand Object

The following builds a CompositeCommand object with a SQL statement and the CompositeConnection object.

try

{

	String sql = "delete from products where ProductID=1111";

   CompositeCommand cmd = new CompositeCommand(sql, conn);

}

catch (Exception ex)

{

	Throw ex;

}

Using the conn.CreateCommand Method to Create the CompositeCommand Object

The following retrieves a CompositeCommand object by calling the conn.CreateCommand method. Set the SQL statement to cmd before using it to access TDV.

try

{

	CompositeCommand cmd = conn.CreateCommand(); 

	cmd.CommandText = "delete from products where ProductID=1111";

}

catch (Exception ex)

{

	Throw ex;

}

Using CompositeCommand to Create the CompositeCommand Object

Use the following to create a new object. Call the CompositeCommand default constructor and set the CommandText and Connection objects before using it.

try

{

	CompositeCommand cmd = new CompositeCommand(); 

	cmd.CommandText = "delete from products where ProductID=1111";

	cmd.Connection=conn;

}

catch (Exception ex)

{

	Throw ex;

}
