    Hello,

    Just a quick question:

    I've got two tables, galleryInfo and gallery, Gallery info contains a column 'eventID' there are several rows in the gallery table with the column 'event' that should be deleted when I run this query

    [PHP]DELETE
    FROM gallery
    WHERE event =(SELECT eventID FROM galleryInfo WHERE ID = 20 ) [/PHP]

    I've also tried:
    [PHP]DELETE
    FROM gallery
    WHERE event IN (SELECT eventID FROM galleryInfo WHERE ID = 20 ) [/PHP]

    The subquery will only ever return one row. Can anyone help?

    Are gallery.event and galleryinfo.eventID linked?

    Oh duh, just went to post two screen shots from PHP my admin showing how the data is linked. Turns out there were no images in the gallery for that event. *facepalm*

    Thanks Jethropool :)
