You have to use ORDER BY
in OVER
clause for that
ROW_NUMBER() OVER (ORDER BY column_name [ASC|DESC]) AS R

Good Evening, I currently study the ROW_NUMBER()
in squirrel sql. I success to retrieve data from the database, but the problem is the R in the ROW_NUMBER() OVER () AS R
does not match with the sorted database data. Need some suggestion and hints for the query below, thanks
Query
SELECT COUNT(*) AS RECORDS FROM (SELECT ROW_NUMBER() OVER () AS R,
somethingAisID, somethingB, somethingC ORDER BY somethingA ) AS T WHERE R>=0
AND R<=100
p/s: The database rows is sorted, but the R fields is match with the un-sorted database rows.
Example:
the somethingAisID
which sorted from the query is 1,2,3,4,5
the somethingAisID
which un-sorted from the original database table is 4,5,2,3,1
then the R is match as 4,5,2,3,1
How can I query the R to match as 1,2,3,4,5? (sorted query)
