Branch: default
Log Message:
On some platforms we got error:
QUERY = select count(*), 1 from (
(select this_column from table_one)
intersect
(select this_column from table_two)
) as "existing"
union all
select count(*), 0 from (
(select this_column from table_one)
except
(select this_column from table_two)
) as "missing";
ERROR = !inputs not the same size.
Apparently the union detects different output signatures of the first and
second query.
This occurs in default branch on platforms:
mac-mini Cla-Dar-i64 (without assert propcheck)
lab05 GNU-Fed-i64 (without assert propcheck)
solaris Sol-Sol-i64
zonnestraal GNU-Sol-s32
win2012 Int-Win-i32
win2012 Mic-Win-i32
win2012 Mic-Win-i64
lab03 Int-Win-i32
lab03 Mic-Win-i32
But strangely not on:
mac-mini Cla-Dar-i64 (with assert propcheck)
lab05 GNU-Fed-i64 (with assert / propcheck / not_int128)
win2012 Int-Win-i64
lab03 Int-Win-i64
lab03 Mic-Win-i64
To get a stable output I added explicit cast to bigint for the count(*) column
in this query.
Once this works on default, we can repeat this patch on Dec2016 branch where it
occurs on platforms:
zonnestraal GNU-Sol-s32
win2012 Int-Win-i32
lab03 Int-Win-i32
lab03 Int-Win-i64
But strangely not on:
win2012 Int-Win-i64
