Perform an Insert, Update, or Delete operation with AseCommand object using the ExecuteNonQuery function.
The ExecuteNonQuery function issues a command (SQL statement or stored procedure) that does not return a result set.
If you want to set the isolation level for a command, you must use the AseCommand object as part of an AseTransaction object. When you modify data without an AseTransaction object, Adaptive Server ADO.NET Data Provider operates in autocommit mode, and any changes that you make are applied immediately.
