Semantics

label

Identifies either a block or a statement (see the syntax diagrams plsql_block ::= and statement ::= and the description of label).

If the GOTO statement cannot find label in the current block, it transfers control to the first enclosing block in which label appears.

Usage

If a GOTO statement exits a cursor FOR loop prematurely, the cursor closes.

GOTO Statement Restrictions

• A GOTO statement cannot transfer control into an IF statement, CASE statement, LOOP statement, or sub-block.

• A GOTO statement cannot transfer control from one IF statement clause to another, or from one CASE statement WHEN clause to another.

• A GOTO statement cannot transfer control out of a subprogram.

• A GOTO statement cannot transfer control from an exception handler back into the current block. However, a GOTO statement can transfer control from an exception handler into an enclosing block.
