I need to get the results from two different queries by substracting results from query A from query B in mySQL. I know how to do it in php however I need this as a mysql query. Is this possible?

Query A:

SELECT * FROM listmain WHERE listmain.fibu1 = 0 AND mitarbeiterid = %s AND listmain.vaz = 1 AND listmain.year2 = YEAR(CURDATE()) UNION SELECT * FROM listmain WHERE listmain.fibu1q = 0 AND mitarbeiterid = %s AND listmain.vaz = 2 AND listmain.year2 = YEAR(CURDATE()) UNION SELECT * FROM listmain WHERE listmain.fibu1y = 0 AND mitarbeiterid = %s AND listmain.vaz = 3 AND listmain.year2 = YEAR(CURDATE())

Query B:
SELECT * FROM listmain WHERE mitarbeiterid = %s AND listmain.vaz <> 0 AND listmain.vaz <> 4 AND listmain.year2 = YEAR(CURDATE()) AND listmain.fibu1 = 1 AND listmain.ust1 = 1

I am actually also interested if there is a possibility to use any Arithmetic Operators between different queries. One way is with UNION for Addition but how can I do this for any other Arithmetic Operators?

thank you
