Edit... I didn't like the solution I posted...
Solution to what? 😀
It was just a rewrite of the original code Sales.Customer code.
I didn't like it... So I killed it. 😀

Did it look like this?

;WITH FilterTable AS (

-- This could be a #temp table, a table v@riable or even a table-valued parameter:

SELECT StoreID, AccountNumber, rowguid

FROM (VALUES

(934, 'AW00000001', '3F5AE95E-B87D-4AED-95B4-C3797AFCB74F'),

(928, 'AW00000010', 'CDB6698D-2FF1-4FBA-8F22-60AD1D11DABD'),

(1252, 'AW00000100', '7D37485D-A4CF-4C08-8D3C-364DEEC7C841'),

(1186, 'AW00000200', '7C96C878-A038-4B2F-825F-016C922D6407'),

(386, 'AW00000300', '7256F9B7-5253-4384-B8DE-60B6F0ADF5A6')

) d (StoreID, AccountNumber, rowguid)

)

SELECT c.*

FROM Sales.Customer c

INNER JOIN FilterTable f

ON f.StoreID = c.StoreID

AND f.AccountNumber = c.AccountNumber

AND f.rowguid = c.rowguid

All I am asking is simple questions. Please forget what I am trying to accomplish or what I am trying get.

After running below query (AdventureWorks database). I get 7 columns with 5 rows. My question is, is there any alternative way to this script to get exact same results. Another word, can this query be tuned? or this is the only way to get the result what I get? (plz run the script against AvdentureWork to see the result)

Hope I made clear to everyone.

Thanks everyone for your patience and time.

select * from Sales.Customer where

StoreID = 934 and AccountNumber = 'AW00000001' and rowguid = '3F5AE95E-B87D-4AED-95B4-C3797AFCB74F'

or

StoreID = 928 and AccountNumber = 'AW00000010' and rowguid = 'CDB6698D-2FF1-4FBA-8F22-60AD1D11DABD'

or

StoreID = 1252 and AccountNumber = 'AW00000100' and rowguid = 'E789F6DD-3159-4DDC-81A8-8571C571656E'

or

StoreID = 1186 and AccountNumber = 'AW00000200' and rowguid = '7C96C878-A038-4B2F-825F-016C922D6407'

or

StoreID = 386 and AccountNumber = 'AW00000300' and rowguid = '7256F9B7-5253-4384-B8DE-60B6F0ADF5A6'

The post above your last post offers a suggestion.

SELECT c.*

INNER JOIN FilterTable f

Very similar... CTE had a different name and I use a "WHERE EXISTS" instead if the INNER JOIN...
