Hi all, I've done a match on records by postal code and 30 of the records don't match up. I tried the following to try and select all records that were matched in the original table and then use the invert selection tool to find all those records that didn't match.
Select * From IH_All_Babies Where Study_# In (Select Study_# From Matched) However when I try to run the syntax MapInfo goes into Not Responding mode. I have almost 17,000 records, would too many records be the problem? If anyone has any ideas that would be great. Thanks, Christine
