Need to select records that match and then those that don't match from the 2 tables (See attached)
Would like to compare Table A statid to Table B statid and if those don't match, try to match on Table A id2 with TableB Id2 (or vice versa..whatever works).
 I have to account for NULLS and blanks in the statid & id2 fields. I have thousands of recs in each file.
Thank you!

those that do match:
SELECT * FROM tableA a JOIN tableB b on a.statid = b.statid

those in A but not in B:
SELECT a.* FROM tableA a LEFT JOIN tableB b on a.statid = b.statid WHERE b.statid IS NULL

those in B but not in A:
SELECT a.* FROM tableB B LEFT JOIN tableA a on a.statid = b.statid WHERE a.statid IS NULL
