How to make joins in my criteria in SQL SERVER? - sql

Question

I have three tables:
**1.FT_ViewItemMovement **
StoreID ItemLookupCode QTY
-------------------------------
1001 11121111 222
1001 11121111 1
1201 11121111 333
1201 11121111 2
2.Item
ItemLookupCode ID
------------------------
11121111 111
3.ItemDynamic
ItemID StoreID SnapShotQuantity
-------------------------------------
111 1201 50
111 1001 25
111 5000 75
111 7777 100
Expecting Result
ItemID StoreID QTY SnapShotQuantity
-------------------------------------
111 1201 335 50
111 1001 223 25
111 5000 0 75
111 7777 0 100
I Tried this following Query, But I didn't get
SELECT
ViewItemMovement.ItemLookupCode,
ViewItemMovement.StoreID,
Sum(ViewItemMovement.Quantity) Quantity,
ItemDynamic.SnapShotQuantity SanpShotQuantity
FROM
FT_ViewItemMovement ViewItemMovement
left join Item with(NoLock) on Item.ItemLookupCode = ViewItemMovement.ItemLookupCode
left join ItemDynamic with(NoLock) on ItemDynamic.ItemID = Item.ID and ItemDynamic.StoreID = ViewItemMovement.StoreID
WHERE brand = 'PEPSI'
Group By
ViewItemMovement.ItemLookupCode,
ViewItemMovement.StoreID,
ViewItemMovement.ItemDescription,
ViewItemMovement.Brand,
Item.Cost,
ItemDynamic.SnapShotQuantity
first I want to summarise the quanity of FT_ViewItemMovement.Qty by StoreID and ItemLookupCode and then if it matches the same itemID with ItemDynamic it has to bring SnapShotQuanity
If there is no FT_ViewItemMovement.Qty, then show FT_ViewItemMovement.Qty = 0 as Expecting output

Answer 1

Simplify your query by looking at what you need, which is two SUM's and a GROUP BY containing the other selections, while using StoreID from FT_ViewItemMovement to allow the SUM(v.QTY) to work.
SELECT id.ItemID, v.StoreID, SUM(v.QTY), SUM(id.SnapShotQuantity)
FROM FT_ViewItemMovement v
INNER JOIN Item i ON v.ItemLookupCode = i.ItemLookupCode
INNER JOIN ItemDynamic id ON i.ID = id.ItemID
GROUP BY id.ItemID, v.StoreID

Answer 2

Your GROUP BY clause looks too complicated. I think this is what you want:
SELECT vim.ItemLookupCode, vim.StoreID,
COALESCE(Sum(vim.Quantity), 0) as Quantity,
id.SnapShotQuantity as SanpShotQuantity
FROM FT_ViewItemMovement vim LEFT JOIN
Item i
ON i.ItemLookupCode = vim.ItemLookupCode LEFT JOIN
ItemDynamic id
ON id.ItemID = i.ID and id.StoreID = vim.StoreID
WHERE vim.brand = 'PEPSI'
GROUP BY vim.ItemLookupCode, vim.StoreID,
id.SnapShotQuantity;
Your WHERE clause references brand. I have no idea where that comes from based on your question.

Answer 3

With your data sample, you must select from ItemDynamic then use join other table.
I hope it will work for you.
SELECT
ItemDynamic.ItemID,
ItemDynamic.StoreID,
SUM(ViewItemMovement.Quantity) AS Quantity,
MAX(ItemDynamic.SnapShotQuantity) AS SanpShotQuantity
FROM
ItemDynamic with(NoLock)
left join Item with(NoLock) on Item.ID = ItemDynamic.ItemID
left join FT_ViewItemMovement ViewItemMovement on ViewItemMovement.ItemLookupCode = Item.ItemLookupCode and ViewItemMovement.StoreID = ItemDynamic.StoreID
Group By
ItemDynamic.ItemID,
ItemDynamic.StoreID
