The first parameter (rsNameTarget) is the ResultSet that will be modified by the merge.
The second parameter (rsNameSource) is the ResultSet containing the rows that will be merged into the target.
The third parameter (rsCommonField) is the field that occurs in both results sets that will be used as the test for which rows to remove from
Returns TRUE if the function is successful.
Returns FALSE if the function fails.
