PL/SQL categories of control statements are: Conditional selection statements, which run different statements for different data values. The conditional selection statements are IF and CASE.

Summary: in this tutorial, you will learn how to use the PL/SQL IF statement to either execute or skip a sequence of statements based on a specified condition. The IF statement allows you to either execute or skip a sequence of statements, depending on a condition. The IF statement has the three forms: – IF THEN – IF THEN ELSE – IF THEN ELSIF The IF statement associates a condition with a sequence of statements enclosed by the keywords THEN and END IF. If the condition is TRUE, the statements get executed, and if the condition is FALSE or NULL, then the IF statement does nothing. Logically speaking, the IF-THEN-ELSIF construct is one way to implement CASE statement functionality in PL/SQL. Of course, if you are using Oracle9 i Database onwards, you are probably better off actually using a CASE statement (discussed later in this chapter). Each ELSIF clause must have a THEN after its condition. IF-THEN Statement The IF-THEN statement is mainly used to execute a particular section of codes only when the condition is satisfied.
