MySQL IF/WHEN/ELSE/OR with ORDER BY FIELD
Let us first create a table −
mysql> create table DemoTable1884 ( Marks int ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1884 values(55); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1884 values(97); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1884 values(79); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1884 values(87); Query OK, 1 row affected (0.00 sec)
Display some records in the table using insert command −
mysql> select * from DemoTable1884;
This will produce the following output −
+-------+ | Marks | +-------+ | 55 | | 97 | | 79 | | 87 | +-------+ 4 rows in set (0.00 sec)
Here is the query to implement order by field() with OR:
mysql> select * from DemoTable1884 where Marks = 98 or Marks = 87 order by field(Marks,98,87) limit 1;
This will produce the following output −
+-------+ | Marks | +-------+ | 87 | +-------+ 1 row in set (0.00 sec)
