I have a table with 2 columns one is BIGINT which is Generated always starting
with 1 and increment by1 and the other one is timestamp
ij> select id,date from inbox where id = 0<3;
ID |DATE
-----------------------------------------------
25 |2006-01-26 14:35:46.584
34 |2006-01-26 14:36:16.588
21 |2006-01-26 14:34:46.455
22 |2006-01-26 14:34:47.176
27 |2006-01-26 14:35:47.054
24 |2006-01-26 14:35:16.58
28 |2006-01-26 14:35:47.305
35 |2006-01-26 14:36:18.771
31 |2006-01-26 14:35:48.496
32 |2006-01-26 14:35:48.887
33 |2006-01-26 14:35:49.308
11 rows selected
ij> select id,date from inbox where id = true;
ID |DATE
-----------------------------------------------
21 |2006-01-26 14:34:46.455
1 row selected
Both queries should return same number of rows
Also If I delete the first row from the table then select id,date from inbox
where id = true; returns the second row
ij> delete from inbox where id=21;
1 row inserted/updated/deleted
Then again run
ij> select id ,date from inbox where id=true;
ID |DATE
-----------------------------------------------
22 |2006-01-26 14:35:16.58
Which indicates that the select returns only the first row and then is getting
closed
