Could you use the ICASE function? SELECT amount = ICASE( ; f1>f2 AND f1>f3 AND f1>f4, f1, ; f2>f3 AND f2>f4 AND f2>f1, f2, ; f3>f4 AND f3>f1 AND f3>f2, f3, ; f4>f1 AND f4>f2 AND f4>f3, f4) ; FROM results Ugh! In SQL Server you could do: SELECT MAX(amount) FROM ( SELECT amount = MAX(amount) FROM table1 UNION ALL SELECT amount = MAX(amount) FROM table2 UNION ALL SELECT amount = MAX(amount) FROM table3 UNION ALL SELECT amount = MAX(amount) FROM table4 ) AS results Don't think VFP supports this syntax.
