To perform an insert, update, or delete with the SACommand object, use the ExecuteNonQuery function. The ExecuteNonQuery function issues a query (SQL statement or stored procedure) that does not return a result set.
You can only make changes (inserts, updates, or deletes) to data that is from a single table. You cannot update result sets that are based on joins. You must be connected to a database to use the SACommand object.
For information about obtaining primary key values for AUTOINCREMENT primary keys, see SACommand: Retrieve primary key values for newly inserted rows.
To set the isolation level for a SQL statement, you must use the SACommand object as part of an SATransaction object. When you modify data without an SATransaction object, the provider operates in autocommit mode and any changes that you make are applied immediately. See Transaction processing.
