A
PL/SQL supports three groups of execution control statements:
- IF Statements - Conditionally executes a block of statements.
- CASE Statements - Selectively executes a block of statements.
- LOOP Statements - Repeatedly executes a block of statements.
- GOTO Statements - Unconditional changes the execution flow to a specified statement.
The script below shows some execution control statements:
DECLARE
total NUMBER;
BEGIN
total := 0;
LOOP
total := total+1;
IF total >= 10 THEN
GOTO print;
END IF;
END LOOP;
<>
DBMS_OUTPUT.PUT_LINE('Total counts: ' || TO_CHAR(total));
END;
This script should print this:
Total counts: 10`
