(2) If an ORDER BY term is a simple identifer (like "x", not "x.y" and not "x.y.z") and if there if the k-th column uses that same identifer as an AS alias, the sort by the k-th column.
CREATE TABLE a(x,y); INSERT INTO a VALUES(1,8); INSERT INTO a VALUES(9,2); SELECT x AS y FROM a ORDER BY y; In older versions of SQLite, the SELECT statement above would return 9, 1 since the ORDER BY term evaluated to the expression a.y by rule (3) In the next release, because of the addition of rule (2) above, the result will be 1, 9.
I don't understand. If I say "ORDER BY y" aren't I saying sort the result set based on the column " as y" of the result set, not the table "a.y"?
ie they should come out y 9 1 That's what (2) says to me Cheers. -- Dr Gerard Hammond http://www.macsos.com.au Cheers. -- Dr Gerard Hammond http://www.macsos.com.au Cheers. -- Dr Gerard Hammond Garvan Institute of Medical Research ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
