As the name implies, PL/SQL supports programming language features like conditional statements, iterative statements.
The programming constructs are similar to how you use in programming languages like Java and C++. In this section I will provide you syntax of how to use conditional statements in PL/SQL programming.
IF THEN ELSE STATEMENT
1) IF condition THEN statement 1; ELSE statement 2; END IF; 2) IF condition 1 THEN statement 1; statement 2; ELSIF condtion2 THEN statement 3; ELSE statement 4; END IF 3) IF condition 1 THEN statement 1; statement 2; ELSIF condtion2 THEN statement 3; ELSE statement 4; END IF; 4) IF condition1 THEN ELSE IF condition2 THEN statement1; END IF; ELSIF condition3 THEN statement2; END IF;
