Conditional Statements in PL/SQL

 

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;
