Oracle Tutorials - Types of Execution Flow Control Statements
(Continued from previous topic...)
What Are the Execution Control Statements?
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:
total := 0;
total := total+1;
IF total >= 10 THEN
DBMS_OUTPUT.PUT_LINE('Total counts: ' || TO_CHAR(total));
This script should print this:
Total counts: 10
