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;
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
Your description is correct, but your output is in the wrong order. The
default sort order is ascending so the 9 will sort after the 1.
Y
1
9
