Set custom messages for enum values in MySQL
Use the if else to set custom messages for enum. Let us first create a table −
mysql> create table DemoTable1992
(
ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
ClientName varchar(20),
isActive ENUM('Y','N')
);
Query OK, 0 rows affected (0.89 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1992(ClientName,isActive) values('Chris','N');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1992(ClientName,isActive) values('Bob','N');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable1992(ClientName,isActive) values('David','Y');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1992(ClientName,isActive) values('Carol','N');
Query OK, 1 row affected (0.19 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1992;
This will produce the following output −
+----------+------------+----------+ | ClientId | ClientName | isActive | +----------+------------+----------+ | 1 | Chris | N | | 2 | Bob | N | | 3 | David | Y | | 4 | Carol | N | +----------+------------+----------+ 4 rows in set (0.00 sec)
Here is the query to set custom messages with if else
mysql> select ClientName,if(isActive='Y','Active Member','Not Active Member') as Result from DemoTable1992;
This will produce the following output −
+------------+-------------------+ | ClientName | Result | +------------+-------------------+ | Chris | Not Active Member | | Bob | Not Active Member | | David | Active Member | | Carol | Not Active Member | +------------+-------------------+ 4 rows in set (0.00 sec)
