There are two physical files named aa and bb. Both have the same fields: TOY# & PART#. Besides these, to file aa, there is a field COMM. And to file bb, there is a field CATE. Now I'd like to update aa.COMM when aa.TOY#=bb.TOY# and aa.PART#=bb.PART# and bb.CATE='60'. Would you please tell how to write the SQL statement?
Assuming you want set AA.COMM equal to bb.CATE, the SQL Update statment would look something like this:
UPDATE aa SET aa.COMM = (SELECT bb.CATE FROM bb WHERE aa.TOY#=bb.TOY# and aa.PART#=bb.PART# and bb.CATE='60')
