here's what the statement looks like:

DELETE FROM videoswatched vw2 
 WHERE vw2.userID IN ( SELECT vw.userID 
                         FROM videoswatched vw
                         JOIN users u ON vw.userID=u.userID
                        WHERE u.companyID = 1000
                     GROUP BY userID )

that looks decent to me, and the SELECT statement works on its own (producing rows with a single column 'userID'.

basically, i want to delete entries in the 'videoswatched' table where the userID in the videoswatched entry, after joining to the users table, is found to have companyID=1000.

how can i do this without getting the error in my sql syntax? it says the error is near:

vw2 WHERE vw2.userID IN (
    SELECT vw.userID FROM videoswatched vw
    JOIN users u

and on line 1. thanks!
