Rick Hillegas updated DERBY-887:
--------------------------------
Fix Version/s: (was: 10.3.0.0)
Detaching this issue from 10.3. Fixing it seems to require changing the
non-ANSI behavior of implicit and explicit casts. Changing this behavior
probably will affect existing applications and it seems to be the sort of fix
which we need to defer to a major release. That is, this is appropriate for
11.0 but not 10.3.

> 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
