I have to combine 2 tables that should have originally been just one table. The first table contained a ClientID (manually entered number) and about 100 columns that were part of a survey. The second table contained the sameClientID and about 60 more columns that were part of the same survey. So now I have a table with one ClientID and all 160 columns but I only have the old data for the first 100 columns . I need to create an UPDATE query that will add the remaining 60 columns data to the table based on the matching ClientID field. I havent figured out how to make this happen with an SQL Server query...please help.
