Обсуждение: Missing value from PostgreSQL query?
Hi all,
Does any one know why I have following inconsistant results from PostgreSQL under Cygwin?
When I switch the select order, or use "select * from patient", some values are missing from returned results.
What might be wrong?
Thanks in advance.
test=# select first_name, last_name, used, birthday from patient;
first_name | last_name | used | birthday
------------+-----------+------+------------
| 1960-02-01DI | N
| 1960-02-01DI | N
(2 rows)
test=# select first_name, last_name, birthday, used from patient;
first_name | last_name | birthday | used
------------+-----------+------------+------
AAAAAA | TDI | 1960-02-01 | N
AAAAAB | TDI | 1960-02-01 | N
(2 rows)
/* worked fine */
est=# select birthday from patient;
birthday
------------
1960-02-01
