Remarks
esriSetUnion
All rows present in the first selection set and all rows in the second are copied to the output selection set. This is a Boolean OR operation
esriSetIntersection
All row IDs present in both input selection sets are copied to the output set. Those row IDs present in only one set are discarded. This is a Boolean AND operation.
esriSetDifference
All rows present in the first selection set but not in the second are copied to the output selection set. This is a Boolean INHIBITION operation.
esriSetSymDifference
All rows present in either of the input selection sets, but not present in both, are copied to the output set. This is a Boolean XOR operation.
