Pading strings with spaces to longest string in queries with union
------------------------------------------------------------------
Key: CORE-5916
URL: http://tracker.firebirdsql.org/browse/CORE-5916
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.3
Environment: WIndows 7
Reporter: Wojtek
Priority: Minor
I have query using union all to add many records to database at one time. But
in each varchar field spaces are added at the end.
There is a sample demonstrating problem:
SELECT
COL,
REPLACE(COL, ' ', '.'),
CHAR_LENGTH(COL),
CHAR_LENGTH(TRIM(COL))
FROM
(
SELECT 'a' AS COL FROM RDB$DATABASE
UNION ALL
SELECT 'bbbbbbb' FROM RDB$DATABASE
UNION ALL
SELECT 'cc' FROM RDB$DATABASE
)
And result:
COL REPLACE CHAR_LENGTH CHAR_LENGTH1
a a...... 7 1
bbbbbbb bbbbbbb 7 7
cc cc..... 7 2
