MySQL query to select the nth highest value in a column by skipping values
To get the nth highest value in a column, you can use LIMIT OFFSET. Here, OFFSET is used to skip the values. Let us first create a table −
mysql> create table DemoTable ( Value int ) ; Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(100); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values(140); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(90); Query OK, 1 row affected (0.08 sec) mysql> insert into DemoTable values(80); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values(89); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values(98); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable values(58); Query OK, 1 row affected (0.10 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+ | Value | +-------+ | 100 | | 140 | | 90 | | 80 | | 89 | | 98 | | 58 | +-------+ 7 rows in set (0.00 sec)
Following is the query to get the nth highest value in a column. Here, we are skipping 3 values using OFFSET 3. The same gives us the 4th highest value after using ORDER BY −
mysql> select Value from DemoTable order by Value limit 1 offset 3;
This will produce the following output −
+-------+ | Value | +-------+ | 90 | +-------+ 1 row in set (0.00 sec)
