A <code>BEGIN WORK</codechgfhghgh
ode> statement in [[SQL]] starts a [[database transaction|transaction]] within a [[relational database management system]] (RDBMS).

Any work done after this point will not be visible to other users, until a <code>[[Commit (SQL)|COMMIT]]</code> statement is issued. A <code>[[Rollback (data management)|ROLLBACK]]</code> statement can also be issued, which will undo any work performed since the <code>BEGIN WORK</code> command. Both <code>COMMIT</code> and <code>ROLLBACK</code> will end the transaction: another <code>BEGIN WORK</code> will need to be issued to start a new one.
