The attacker is attempting to "trick" the database into running a command that was never intended by the website's developers.

The reference to SYSIBM.SYSDUMMY1 is a dead giveaway that the target is an IBM DB2 database. This is a special "one-row, one-column" table used to perform calculations or retrieve system values. The attacker is attempting to "trick" the database
