With this DBM command you send an administration command or SQL statement to the database instance. However, for SQL statements in particular it is intended for use via a programming interface.
Unlike when you use the DBM command db_execute , you want the reply to display one data record after another.
When you execute this command, it implicitly opens a session with the database instance and then ends the session once the command has been executed. This database session is opened in AUTOCOMMIT mode. If you specify an SQL statement, it is automatically completed with a COMMIT statement.
After you execute the administration command or the SQL statement, the system returns an OK message or displays the first data record of the reply. To display the next data record, use the db_fetchnice DBM command.
For more information about SQL statements, see the SQL Reference Manual and SQL Tutorial.
You are working in the session mode of the Database Manager CLI.
If you want to execute administration commands, you need the AccessUtility server authorization.
If you want to execute SQL statements, you need the AccessSQL server authorization.
