> 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
