Folks,
Thanks for the 'help'. Oy.
I figured it out from some help on the Lasso discussion list.
All I had to do was properly address ALL the tables I wanted to touch.
So this:
UPDATE tbe_gallery
SET tbe_gsa.gsa_paperprice = tbe_gallery.gallery_gsaprice_paper
WHERE tbe_gallery.gallery_id = tbe_images.img_rel_id AND
tbe_images.img_orig_filename = tbe_gsa.gsa_id
Should have been This:
UPDATE tbe_gallery, tbe_gsa, tbe_images
SET tbe_gsa.gsa_paperprice = tbe_gallery.gallery_gsaprice_paper
WHERE tbe_gallery.gallery_id = tbe_images.img_rel_id AND
tbe_images.img_orig_filename = tbe_gsa.gsa_id
And viola, it works!
Miles.
