[SOLVED] MySQL If statement with multiple conditions


I want to write IF statement inside a Stored procedure in MySQL in the following way:

IF (exp1 and exp2 and exp3) or exp4

I know MySQL will treat IF() as a function call.
But I hope you got what I’m trying to achieve.
I am new to MySQL syntax.


In a procedure the use of an IF is pretty straight forward:

IF (yourCondition [logical operator(OR, AND) another condition] ) THEN

So in a practical example:

DECLARE m integer;
DECLARE n integer;
SET m = 1;
SET n = 0;
IF ((m>n AND m=1 AND n=0) OR m=n)THEN
     some code here

The evaluation of the conditions follows the parenthesis rule same as in a mathematical operation.
