EXIT Statement

The EXIT statement breaks out of a loop. The EXIT statement has two forms: the unconditional EXIT and the conditional EXIT WHEN. With either form, you can name the loop to be exited. For more information, see "Controlling Loop Iterations: LOOP and EXIT Statements".

Keyword and Parameter Description


An expression that returns the Boolean value TRUE, FALSE, or NULL. It is evaluated with each iteration of the loop. If the expression returns TRUE, the current loop (or the loop labeled by label_name) is exited immediately. For the syntax of boolean_expression, see "Expression Definition".


An unconditional EXIT statement (that is, one without a WHEN clause) exits the current loop immediately. Execution resumes with the statement following the loop.


Identifies the loop exit from: either the current loop, or any enclosing labeled loop.

Usage Notes

The EXIT statement can be used only inside a loop; you cannot exit from a block directly. PL/SQL lets you code an infinite loop. For example, the following loop will never terminate normally so you must use an EXIT statement to exit the loop.


If you use an EXIT statement to exit a cursor FOR loop prematurely, the cursor is closed automatically. The cursor is also closed automatically if an exception is raised inside the loop.
