I have two differnet databases that have different field names, and different datatypes. I need to compare the data between these databases to find out which PK's exist or do not exist. My task is to synchronize the PK's in these tables. I have programmed a tool for the DB updates. Now, I need to find which ID's need the updates.
For example, Database A fieldname "CompanyID" (varchar 50) = Database B fieldname "custno" (char 6)
FROM DB A.tblCompany INNER JOIN DB B.arcust ON
A.CompanyID = B.custno
