Alternative to MySQL CASE WHEN in MySQL
Use IF() method as an alternative to CASE WHEN in MySQL. Let us first create a table −
mysql> create table DemoTable1593 -> ( -> PlayerScore int -> ); Query OK, 0 rows affected (0.44 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1593 values(78); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1593 values(0); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1593 values(89); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1593 values(0); Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1593;
This will produce the following output −
+-------------+ | PlayerScore | +-------------+ | 78 | | 0 | | 89 | | 0 | +-------------+ 4 rows in set (0.00 sec)
Here is the query to use MySQL IF() −
mysql> select if(PlayerScore=0,'',PlayerScore) from DemoTable1593;
This will produce the following output −
+----------------------------------+ | if(PlayerScore=0,'',PlayerScore) | +----------------------------------+ | 78 | | | | 89 | | | +----------------------------------+ 4 rows in set (0.00 sec)
