mysql update query ?

[ClearChaos]

im redoing the tables structures on the back of my site and ive hit a bit of a brick wall, im trying to merge the contents of two tables but i not sure on the syntax

i was thinking i could try something like...

UPDATE productsizes SET productsizes.SizeID = (SELECT sizes.productsize FROM sizes WHERE sizes.SizeID = productsizes.SizeID)

does that make sense ?

rtfm springs to mind, anyway problem solved
