I don't think you need the JOIN. You can have a correlated subquery, i.e., where the WHERE clause inside the subselect refers to a value or values from the outer main query. Also, the WHERE clause you have would apply to the subselect, not to the UPDATE. >Update XLCDBAP.UPC_XREF >set MFR_PROD_DESC_9317= >(select DESC from UDCIINP >where MFR||ITM = MFR_ID_9336||MFR_ITM_9337) >where MFR_PROD_DESC_9317 = ' ' At 02:17 PM 3/28/02 -0500, you wrote: >This message is in MIME format.
