Delete - I can't specify target table?

Question

Why this query doesn\'t work?

DELETE FROM recent_edits 
WHERE trackid NOT IN 
     (SELECT DISTINCT history.trackid 
     FROM history JOIN recent_edits ON h         


        

Answer 1

You can't post-process a table which is locked for deletion. using the hack select * from (query) as Nicola states will generate a temporary table instead of direct access.

Edit - make sure that you give ID to the tables you use since it is nested and will require uniqueID for every table.

Answer 2

Try in this way

DELETE FROM recent_edits 
WHERE trackid NOT IN 
     (select * from (SELECT DISTINCT history.trackid 
     FROM history JOIN recent_edits ON history.trackid=recent_edits.trackid 
     GROUP BY recent_edits.trackid) as t);
