How to add records to query

[AndyPSV]

I've got query.

 

    SELECT * FROM '.PRFX.'sell WHERE draft = "0" '.$e_sql.' AND ID NOT IN (SELECT id_ FROM '.PRFX.'skipped WHERE uid = "'.$u.'") AND ID NOT IN (SELECT id_ FROM '.PRFX.'followed WHERE uid = "'.$u.'") ORDER BY raised DESC '.$sql_limit;

I want to add 3 records by the lowest number of refreshes; best on 5th position

 

they must be unique (so if you connect two UNION ALL...)
