MySQL IF() to display custom YES or NO messages

Let us first create a table −

mysql> create table DemoTable1850      (      OrderStatus varchar(20)      ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1850 values('Yes'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1850 values('No'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1850 values('Yes'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1850 values('Yes'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1850; 

This will produce the following output −

+-------------+ | OrderStatus | +-------------+ | Yes         | | No          | | Yes         | | Yes         | +-------------+ 4 rows in set (0.00 sec)

Here is the query to implement IF() to display custom messages:

mysql> select if(OrderStatus='Yes','Order has been placed','Failed') as Status from DemoTable1850; 

This will produce the following output −

+-----------------------+ | Status                | +-----------------------+ | Order has been placed | | Failed                | | Order has been placed | | Order has been placed | +-----------------------+ 4 rows in set (0.00 sec)
