Question

how to write my sql query correct? I would like to use WHERE clause in query, but I don’t know how is correct. This is my query with mistake:

**SELECT pil.[Buy-from Vendor No_],  pil.No_, pil.Amount, pil.Quantity 
FROM dbo.[„blk“ 2011$Purch_ Inv_ Line]AS pil
WHERE pil.Type=5
LEFT JOIN dbo.[„blk“ 2011$Purch_ Inv_ Header] AS pih
ON pil.[Document No_]=pih.No_
ORDER BY pil.amount**

Answer 1

This is way you have handle left joins

SELECT 
    pil.[Buy-from Vendor No_] 
  ,  pil.No_, pil.Amount
  , pil.Quantity 
FROM dbo.[UAB „Arvi cukrus“ 2011$Purch_ Inv_ Line] pil
LEFT JOIN dbo.[„blk“ 2011$Purch_ Inv_ Header] Pih ON pil.[Document No_]=pih.No_
WHERE pil.Type=5
ORDER BY pil.amount
