BUG: pgAdmin III View table with empty strings

От
"Matej Rizman"
Дата:
Version: 0.8.0 (Jul 14 2003), Win32 version

Steps:
1) create table with one varchar column
CREATE TABLE public.test
( a varchar(50) NOT NULL
) WITHOUT OIDS;

2) fill it with some empty strings
INSERT INTO test(a) VALUES('')

3) run pgAdmin III, select table and choose view data from popup menu

4) pgAdmin III shows two apostrophes ('') instead of empty strings.

Regards,
Matej Rizman

Hi,

That is by design and is described in the new docs/en_US/editgrid.html
file. The two single quotes represents empty string, whereas an empty
box represents NULL.

Might I add my 2 cents worth:
If you have a string type column with a value of lets say two or more spaces
e.g. '   '::text, you cannot see the difference between that and a column that
returns NULL.
May be in this day and age of GUIs, a different colour might help?

Yes, it's going on the wishlist for V2.
