Hello Guys!
I have one query that work with 2 subselect
the query is:
"SELECT prod.*, B.Bounce as Bounce
FROM [SELECT pn, modelo, Count(pn) as ENC from PMarço WHERE tag_atual = 'CDGAR' GROUP BY pn , modelo]. AS prod
LEFT JOIN [SELECT pn, Count(pn) as Bounce from BMarço WHERE day_bnc < 31 AND tag_atual = 'CDGAR' GROUP BY pn]. AS B
ON prod.pn = B.pn"
Ok this is working
now, I would like add more one subselect in my query
is that:
select pn, Count(pn) as NTF from BMarço where day_bnc < 31 AND pbl_desc_atual = 'Defeito não encontrado' AND tag_atual = 'CDGAR' GROUP BY pn
the idea is show select prod.*, B.Bounce as Bounce, here 3subselect.
How can I do ?
tks!

You could create a view, then query the view or add a derived table.

Well, a derived table IS a subselect (as Gail pointed out to me once).

Anyway, i am just guessing since we do not really have enough information to complete this, but try this:

SELECT prod.*, B.Bounce AS Bounce, sub3.NTF

FROM [SELECT pn, modelo, COUNT(pn) AS ENC

FROM PMarço

WHERE tag_atual = 'CDGAR'

GROUP BY pn , modelo]. AS prod

LEFT JOIN [SELECT pn, COUNT(pn) AS Bounce

FROM BMarço

WHERE day_bnc < 31

AND tag_atual = 'CDGAR'

GROUP BY pn]. AS B

ON prod.pn = B.pn

LEFT JOIN [SELECT pn, COUNT(pn) AS NTF

FROM BMarço

WHERE day_bnc < 31

AND pbl_desc_atual = 'Defeito não encontrado'

AND tag_atual = 'CDGAR'

GROUP BY pn] AS sub3

ON prod.pn = sub3.pn

thanks for answer

I Did

SELECT prod.*, B.Bounce AS Bounce, NTF.NTF, (Bounce - NTF.NTF) AS B_Real, ROUND((NTF.NTF/(Bounce)*100),2) AS SDEF, ROUND((B_Real/(prod.ENC)*100),2) AS INDB, ROUND((Bounce/(prod.ENC)*100),2) AS TTB

FROM ([SELECT pn, modelo, Count(pn) as ENC from PMarço WHERE tag_atual = 'SDXGAR' OR tag_atual = 'GAR' GROUP BY pn , modelo]. AS prod

LEFT JOIN [SELECT pn, Count(pn) as Bounce from BMarço WHERE day_bnc < 31 AND tag_atual = 'SDXGAR' OR tag_atual = 'GAR' GROUP BY pn]. AS B

ON prod.pn = B.pn)

LEFT JOIN [SELECT pn, Count(pn) AS NTF FROM BMarço WHERE day_bnc < 31 AND pbl_desc_atual = 'Defeito não encontrado' AND tag_atual = 'SDXGAR' OR tag_atual = 'GAR' GROUP BY pn]. AS NTF

ON B.pn = NTF.pn

this work but for it is necessary to have all Conditions.

for exemplo incase I dont have the condition tag_atual = 'SDXGAR' , it not work well

What Can I do?

You'll have to give us more information.
