Thread Wrong result using 'NOT IN' with sub-select

"Renato Portello"
I just converted a DB from DBISAM 3 to ElevateDB and porting an  =

application.

I found that the following query does work only if I search for 'ABP', f=
or  =

the oter value of 'idFornitore' it return wrong values.

SELECT 'ABP', SpessoreCu
FROM Ramature WHERE NOT SpessoreCu IN
(SELECT SpessoreCU FROM CostoRamatureExt WHERE idFornitore =3D 'ABP')

To explain:
SELECT SpessoreCU FROM CostoRamatureExt WHERE idFornitore =3D 'EPITOME'

return:

SpessoreCU
 17
 35
 70
105
140
210
420

If I launch the following

SELECT 'EPITOME', SpessoreCu
FROM Ramature WHERE SpessoreCu NOT IN
(SELECT SpessoreCU FROM CostoRamatureExt WHERE idFornitore =3D 'EPITOME'=
)

I expect an empty result, but I get the following

Expression   SpessoreCU
EPITOME          35
EPITOME          70
EPITOME         105
EPITOME         140
EPITOME         210
EPITOME         420

The first record (17) is correctly filtered out from the NOT IN clause, =
=

but not the others.

As I said the query work well only for idFornitore =3D 'ABP', for all th=
e  =

other value it give me the same error.

I used ElevateDB 1.05b2.

I attach the complete DB for you to try if.


Thanke

Renato

Renato,

Okay, I found the problem and a fix will be in 1.06.  Unfortunately there is
no workaround at this time.  The issue is that the IN search is finding a
match, but not a match for the correct idFornitore value.
