ISSUE: 3339
|
|
TITLE: count(*) from big table returns negative result
|
|
DESCRIPTION:
|
|
NB: in fact, this test must check data types in SQLDA for columns that are results of aggregated functions
|
|
COUNT and (maybe) SUM.
|
|
As of 2.5, COUNT(*) is still displayed as `LONG` (sql_len = 4 bytes ==> integer, max 2^32-1) rather than INT64.
|
|
Test was made only for 3.0 (as it was said in the ticket header, "Fixed version(s)") and I've added here
|
|
also check for results of aggregating (for smallint, int and bigint) and ranging analytical functions.
|
|
NOTES:
|
|
[30.10.2019] Separated code for 4.0 because of new output types:
|
|
** sum(<bigint>) - its type is "32752 numeric(38)";
|
|
** added new column: sum(<decfloat>) - it will have type "32762 decfloat(34)".
