Question

First I want to make clear this is not a simple LIMIT x,y question. I want to know if it is possible to do a query like the following peuso query.

SELECT *, OFFSET_OF_ROW()
FROM `table` 
WHERE `some_column` = someValue 
ORDER BY `some_other_column`;

the pseudo function OFFSET_OF_ROW() should give the number of rows which would come before the selected row (+1) if there was no condition `some_column = someValue`

Answer 1

This isn’t particularly efficient, but it will do what you want:

select @rownum := 0;
select * from (
    select @rownum := @rownum + 1, id, some_column, sortcol
    from `table`
    order by `sortcol`
) all_rows 
where `some_column` = someValue;
