I run the following query:
SELECT
orderdetails.sku,
orderdetails.mf_item_number,
orderdetails.qty,
orderdetails.price,
supplier.supplierid,
supplier.suppliername,
supplier.dropshipfees,
cost = (SELECT supplier_item.price
FROM supplier_item,
orderdetails,
supplier
WHERE supplier_item.sku = orderdetails.sku
AND supplier_item.supplierid = supplier.supplierid)
FROM orderdetails,
supplier,
group_master
WHERE invoiceid = '339740'
AND orderdetails.mfr_id = supplier.supplierid
AND group_master.sku = orderdetails.sku
I get the following error:
Msg 512, Level 16, State 1, Line 2 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Any ideas?
Try this:
SELECT
od.Sku,
od.mf_item_number,
od.Qty,
od.Price,
s.SupplierId,
s.SupplierName,
s.DropShipFees,
si.Price as cost
FROM
OrderDetails od
INNER JOIN Supplier s on s.SupplierId = od.Mfr_ID
INNER JOIN Group_Master gm on gm.Sku = od.Sku
INNER JOIN Supplier_Item si on si.SKU = od.Sku and si.SupplierId = s.SupplierID
WHERE
od.invoiceid = '339740'
This will return multiple rows that are identical except for the cost
column. Look at the different cost values that are returned and figure out what is causing the different values. Then ask somebody which cost value they want, and add the criteria to the query that will select that cost.
