Blob transliteration may not happen inside the union
----------------------------------------------------
Key: CORE-3489
URL: http://tracker.firebirdsql.org/browse/CORE-3489
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 2.5.0
Reporter: Dmitry Yemanov
Test case (database and connection charset is win1251):
create or alter procedure p_test
returns (
rresult blob sub_type 1 segment size 80 character set unicode_fss)
AS
begin
rresult= 'Тест'; -- text in cp1251
suspend;
end
select rresult
from p_test
union
select rresult
from p_test
The field value is not transliterated. But if a sub-query is executed
separately (without union), then the field value is transliterated properly.
