Invoke a column twice with different conditions - sql

Question

I really appreciate any help with this matter :)
Am Working on a Report now and I had faced some troubles
I have this Query and it work fine , now I want to add a coulmn that is already exist in the query(from the same table) , but this time i'll change the condition of it , BTW the conditions in both of the 2 column are based on one other column
like for example If I have this :
Select Price from ITM1 WHERE PriceList = '1'
and also this
Select Price from ITM1 WHERE PriceList = '10'
how I can write in the same query and let them display in two different column ?
I will put the Query here in case if some one can help me through it :
you can see THE Column Price & PriceList in the lower part of it ,Bolded.
I just need to make the samething again but with a new coulmn name thats it.

Using the IN Operator will give you what you want. However, there are other changes that you can make to your query which would boost performance - but it's out of scope to the question. I'm unclear as to what you're trying to do with the different "columns" Please help explain. Else see #Dave.Gugg's answer which does just that.
SELECT T0.ItemCode,
T0.ItemName,
T0.CardCode,
T0.CodeBars,
T2.UgpCode,
T3.AltQty,
T3.BaseQty,
CASE
WHEN T4.Uomentry = - 1
THEN T0.[BuyUnitMsr]
ELSE t4.UomName
END AS 'UoMName',
T4.UomEntry,
T0.U_CAT_CODE,
T0.U_CAT_NAME,
T1.CardName,

FROM dbo.PDN1

WHERE (dbo.PDN1.ItemCode = T0.ItemCode)
AND (dbo.OPDN.CardCode = T0.CardCode)
ORDER BY dbo.OPDN.DocDate DESC
) AS OQuantity,
(
SELECT TOP (1) PDN1_1.U_AC_QTY_BONUS
FROM dbo.PDN1 AS PDN1_1
INNER JOIN dbo.OPDN AS OPDN_1 ON PDN1_1.DocEntry = OPDN_1.DocEntry
WHERE (PDN1_1.ItemCode = T0.ItemCode)

INNER JOIN dbo.OUGP AS T2 ON T0.UgpEntry = T2.UgpEntry
INNER JOIN dbo.UGP1 AS T3 ON T2.UgpEntry = T3.UgpEntry
INNER JOIN dbo.ITM1 ON T0.ItemCode = dbo.ITM1.ItemCode
AND dbo.ITM1.PriceList IN ('1', '10')
LEFT JOIN dbo.OUOM AS T4 ON T3.UomEntry = T4.UomEntry
WHERE (T0.Series = '65')
AND (
T4.UomEntry = 3
OR T4.UomEntry = '-1'
)
If you want a different column (this may perform better than two joins):
SELECT T0.ItemCode,
T0.ItemName,
T0.CardCode,
T0.CodeBars,
T2.UgpCode,
T3.AltQty,
T3.BaseQty,
CASE
WHEN T4.Uomentry = - 1
THEN T0.[BuyUnitMsr]
ELSE t4.UomName
END AS 'UoMName',
T4.UomEntry,
T0.U_CAT_CODE,
T0.U_CAT_NAME,
T1.CardName,
(
SELECT TOP (1) dbo.PDN1.U_AC_QTY_ORDER
FROM dbo.PDN1
INNER JOIN dbo.OPDN ON dbo.PDN1.DocEntry = dbo.OPDN.DocEntry
WHERE (dbo.PDN1.ItemCode = T0.ItemCode)
AND (dbo.OPDN.CardCode = T0.CardCode)
ORDER BY dbo.OPDN.DocDate DESC
) AS OQuantity,
(
SELECT TOP (1) PDN1_1.U_AC_QTY_BONUS
FROM dbo.PDN1 AS PDN1_1
INNER JOIN dbo.OPDN AS OPDN_1 ON PDN1_1.DocEntry = OPDN_1.DocEntry
WHERE (PDN1_1.ItemCode = T0.ItemCode)
AND (OPDN_1.CardCode = T0.CardCode)
ORDER BY OPDN_1.DocDate DESC
) AS BQuantity,
CASE
WHEN ITM1.PriceList = '1'
THEN ITM1.Price
ELSE '0'
END AS Price1,
CASE
WHEN ITM1.PriceList = '10'
THEN ITM1.Price
ELSE '0'
END AS Price2,
T0.U_DISC_PER
FROM dbo.OITM AS T0
INNER JOIN dbo.OCRD AS T1 ON T0.CardCode = T1.CardCode
INNER JOIN dbo.OUGP AS T2 ON T0.UgpEntry = T2.UgpEntry
INNER JOIN dbo.UGP1 AS T3 ON T2.UgpEntry = T3.UgpEntry
INNER JOIN dbo.ITM1 ON T0.ItemCode = dbo.ITM1.ItemCode
AND dbo.ITM1.PriceList IN ('1', '10')
LEFT JOIN dbo.OUOM AS T4 ON T3.UomEntry = T4.UomEntry
WHERE (T0.Series = '65')
AND (
T4.UomEntry = 3
OR T4.UomEntry = '-1'
)

Answer 2

You should be able to just join to the table a second time, but you will need to make the joins outer:
SELECT T0.ItemCode ,
T0.ItemName ,
T0.CardCode ,
T0.CodeBars ,
T2.UgpCode ,
T3.AltQty ,
T3.BaseQty ,
CASE WHEN T4.Uomentry = -1 THEN T0.[BuyUnitMsr]
ELSE t4.UomName
END AS 'UoMName' ,
T4.UomEntry ,
T0.U_CAT_CODE ,
T0.U_CAT_NAME ,
T1.CardName ,
( SELECT TOP ( 1 )
dbo.PDN1.U_AC_QTY_ORDER
FROM dbo.PDN1
INNER JOIN dbo.OPDN ON dbo.PDN1.DocEntry = dbo.OPDN.DocEntry
WHERE ( dbo.PDN1.ItemCode = T0.ItemCode )
AND ( dbo.OPDN.CardCode = T0.CardCode )
ORDER BY dbo.OPDN.DocDate DESC
) AS OQuantity ,
( SELECT TOP ( 1 )
PDN1_1.U_AC_QTY_BONUS
FROM dbo.PDN1 AS PDN1_1
INNER JOIN dbo.OPDN AS OPDN_1 ON PDN1_1.DocEntry = OPDN_1.DocEntry
WHERE ( PDN1_1.ItemCode = T0.ItemCode )
AND ( OPDN_1.CardCode = T0.CardCode )
ORDER BY OPDN_1.DocDate DESC
) AS BQuantity ,
dbo.ITM1.Price ,
ITM1Second.Price,
T0.U_DISC_PER
FROM dbo.OITM AS T0
INNER JOIN dbo.OCRD AS T1 ON T0.CardCode = T1.CardCode
INNER JOIN dbo.OUGP AS T2 ON T0.UgpEntry = T2.UgpEntry
INNER JOIN dbo.UGP1 AS T3 ON T2.UgpEntry = T3.UgpEntry
LEFT OUTER JOIN dbo.ITM1 ON T0.ItemCode = dbo.ITM1.ItemCode
AND dbo.ITM1.PriceList = '10'
LEFT OUTER JOIN dbo.ITM1 ITM1Second ON T0.ItemCode = ITM1Second.ItemCode
AND ITM1Second.PriceList = '1'
LEFT OUTER JOIN dbo.OUOM AS T4 ON T3.UomEntry = T4.UomEntry
WHERE ( T0.Series = '65' )
AND ( T4.UomEntry = 3
OR T4.UomEntry = '-1'
)
