Folks
I have a query with error 🙁
ssql = "SELECT b.pn_bnc, b.model_bnc, Count(b.pn_bnc) AS Bounce, (SELECT COUNT(Bounce.laudo_new) FROM Bounce WHERE (Bounce.laudo_new = 'Sem defeito') AND (Bounce.bnc90d = b.bnc90d)) AS NTF FROM Bounce AS b WHERE(((b.bnc90d) = 'VERDADEIRO')) GROUP BY b.pn_bnc, b.model_bnc, b.bnc90d"
when I run the query, for "NTF" return the sum but isn't group by pn_bnc
what can be?
Tks!

It would actually group the rows by columns b.pn_bnc, b.model_bnc and b.bnc90d. And also you have a sub-query executing for each row, will not scale well in production.

Here is another way do this...

SELECTb.pn_bnc, b.model_bnc, b.bnc90d, COUNT( b.pn_bnc ) AS Bounce,

COALESCE( t.Total, 0 ) AS AS NTF

FROMBounce b

LEFT JOIN

(

SELECTbnc90d, COUNT( Bounce.laudo_new ) AS Total

FROMBounce

WHERElaudo_new = 'Sem defeito'

GROUP BY bnc90d

) t on b.bnc90d = t.bnc90d

WHEREb.bnc90d = 'VERDADEIRO'

GROUP BY b.pn_bnc, b.model_bnc, b.bnc90d, t.Total

The solution provided is for SQL Server 2000 or higher and wouldn't run in MS Access or any other RDBMS.

Or, you could try posting in the "Access" forum 😉

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
