Question

I would like to know if there is a way to return the current index of each row in a MySQL query, for example:

SELECT current_index, name FROM table LIMIT 10,10

So that the resulting rows would have

10, 'somename',
11, 'somename',
etc....

It would be a value based on the starting limit value.

Answer 1

SET @rn = 10;

SELECT  @rn := @rn + 1 AS current_index,
        name
FROM    mytable
LIMIT   10, 10

Please note that LIMIT 10, 10 means entries 11 to 20.

Also note that LIMIT without a stable ORDER BY is not guaranteed to persist from query to query (and does not persist in some engines).
