IFNULL in MySQL

Last Updated : 3 Mar, 2018
Given a TABLE, in this TABLE, it prints entry of the table. If table is empty then it gives NULL. Examples:
QUESTION : Given an employee table, print name from the given table which id equals to 2. 👁 Image
Output : Geek2 QUESTION : Given same Employee table, print name from the given table which id equals to 5. Output : NULL
Approach: In this case, we use here IFNULL. IFNULL print the null if the table is an empty or other condition. Query:-
SELECT 
IFNULL(
 (SELECT NAME 
 from employee
 where id = 2),
 'NULL') as NAME;
Output:-
Geek2
Query:-
SELECT 
IFNULL(
 (SELECT NAME 
 from employee
 where id = 5),
 'NULL') as NAME;
Output:-
NULL
