The following bug has been logged online:
Bug reference: 5490
Logged by: Farid Zidan
Email address: fa...@zidsoft.com
PostgreSQL version: 8.4.1
Operating system: Windows XP 32-bit
Description: Using distinct for select list causes insert of
timestamp string literal to fail
Details:
If you use keyword 'distinct' for the source select of the insert statement
the insert fails. Insert succeeds if 'distinct' is not used in select list.
Example,
create table test_insert (
col1 char(8) not null,
col2 TIMESTAMP not null default CURRENT_TIMESTAMP);
insert into
test_insert
(col1, col2) values
('a', '2010-04-30 00:00:00');
insert into test_insert
(col1, col2)
select distinct
'b',
'2010-04-30 00:00:00'
ERROR: column "col2" is of type timestamp without time zone but expression
is of type text
LINE 16: '2010-04-30 00:00:00'
^
HINT: You will need to rewrite or cast the expression.
