SQL 92 answer.
Re: can i wrire a query which sum up more than 2 columns in a single table?
Doesn't this work:
SELECT sum(col1+col2+col3) FROM theTable? And I can resist posting a variant using unions:
SELECT sum(col) FROM (SELECT sum(c1) AS col FROM t union ALL SELECT sum(c2) AS col FROM t union ALL SELECT sum(c3) FROM t) AS theTablePlease, tell us if this helps.
