Merge Operators

To determine the combination of records when you merge queries, you can combine them with the following merge operators:

• And — Records that exist in both queries are included in the merged query.

• Or — Records that exist in either query are included in the merged query.

• Xor — Records that exist in either the primary or secondary query but not both only are included in the merged query.

• Sub — Records that exist only in the primary query are included. This operator subtracts records in the secondary from the primary query. For example, you may want to create a merged query of donors that have given in the past but are not alumni.
