EXIT statement
Applies to ❌ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
A safer way to jump to labels than via GOTO is to use EXIT (jumping out of a LOOP, or block, or other statement) or CONTINUE (skipping a LOOP iteration).
For example, in the absence of more sophisticated LOOP syntaxes, you may choose to exit a loop using EXIT (which translates to LEAVE or BREAK in some dialects, and works the same way as Java's break):
Without a label
-- PL/SQL LOOP i := i + 1; EXIT WHEN i > 10; END LOOP;
// All dialects loop( i.set(i.plus(1)), exitWhen(i.gt(10)) )
With a label
-- PL/SQL <<label>> LOOP i := i + 1; EXIT label WHEN i > 10; END LOOP;
// All dialects
Label label = label("label");
label.label(loop(
i.set(i.plus(1)),
exit(label).when(i.gt(10))
))
Dialect support
This example using jOOQ:
loop(i.set(i.plus(1)), exitWhen(i.gt(10)))
Translates to the following dialect specific expressions:

LOOP SET i = (i + 1); EXIT WHEN i > 10; END LOOP

SET i = (i + 1);

BREAK;
