My understanding is:
select a, b from t1
union
My understanding is:
select a, b from t1
union
select b, a from t1
is equivalent to
select a as a, b as b from t1
union
select b as a, a as b from t1
And therefore, the first sql statement controls the resulting column names,
and the order by applies to the column names (transitively)
Consider this query:
SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY a,b;
Is the query above equalent to:
(1) SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY 1,2;
Or is it the same as:
(2) SELECT a, b FROM t1 UNION SELECT b, a FROM t1 ORDER BY 2,1;
