How to Get the Row Position of a Specific Entry in a MySQL `ORDER BY` Query?

Select row position in MySQL ORDER BY query

Suppose there is a MySQL table with two columns id and name, and the goal is to retrieve a single row and its position in the table sorted by the name column in ascending order. The desired result format is a table with columns id, position, and name.

To do this, you can use a subquery combined with user variables:

<code class="language-sql">SELECT x.id,
       x.position,
       x.name
  FROM (SELECT t.id,
               t.name,
               @rownum := @rownum + 1 AS position
          FROM TABLE t
          JOIN (SELECT @rownum := 0) r
      ORDER BY t.name) x
 WHERE x.name = 'Beta';</code>

In this query, the subquery calculates the position of each row based on the order of the name values. User-defined variable @rownum is used to assign unique positions. The main query then filters the results to get the desired name value "Beta".

Alternatively, the following query provides rankings that solve cases with the same name:

<code class="language-sql">SELECT t.id,
       (SELECT COUNT(*)
          FROM TABLE x
         WHERE x.name <= t.name) AS position,
       t.name
  FROM TABLE t
 WHERE t.name = 'Beta';</code>

This query calculates the position by counting the number of rows with a name value less than or equal to the current row's name value. Both methods provide a way to determine the position of rows in a sorted result set.
