How to Join Files Join Key Fields and ‘Like Fields’ in both files  Prevents duplicate data Transaction File is the primary file  U4TRND should be primary file  Queries run faster Use Correct type of join

Joining Files Types of Joins 1 – Matched Records Selects only records that have matching records in ALL the files. 2 - Matched Records with Primary File Selects every record from the primary file and includes all the matching records from all other files. 3 Unmatched Records with Primary File Selects every primary record that does not have a match in all the secondary files.
