MSSQL UNION var types mismatch

Question

Question asked before and I believe I did all necessary conversions, yet I'm getting error: Error converting data type nvarchar to float . The error message is referencing to SnapperMusic_Winman - View1

View1:

SELECT     Products.ProductId AS Product, Products.ProductDescription AS Description, CONVERT(datetime, PurchaseOrders.EffectiveDate) AS OrderDate, 
                      Suppliers.SupplierId AS SupplierAcc, Suppliers.SupplierName, CONVERT(datetime, Inventory.EffectiveDate) AS BookedDate, CONVERT(float, Inventory.Quantity) 
                      AS Quantity, CONVERT(float, Inventory.TotalValue) AS TotalValue, Locations.LocationId AS Location, PurchaseOrders.PurchaseOrderId AS PONumber, 
                      GoodsReceipts.GoodsReceiptId AS GoodsReference

View2:

Union:

SELECT     dbo.Elen_GoodsInReceived_Winman.Product, dbo.Elen_GoodsInReceived_Winman.Description, dbo.Elen_GoodsInReceived_Winman.OrderDate, 
                      dbo.Elen_GoodsInReceived_Winman.SupplierAcc, dbo.Elen_GoodsInReceived_Winman.SupplierName, dbo.Elen_GoodsInReceived_Winman.BookedDate,

                      dbo.Elen_GoodsInReceived_Winman.PONumber, dbo.Elen_GoodsInReceived_Winman.GoodsReference
FROM         dbo.Elen_GoodsInReceived_Winman
UNION
SELECT    dbo.Elen_GoodsInReceived_Sage.Product, dbo.Elen_GoodsInReceived_Sage.Description, dbo.Elen_GoodsInReceived_Sage.OrderDate, 
                      dbo.Elen_GoodsInReceived_Sage.SupplierAcc , dbo.Elen_GoodsInReceived_Sage.SupplierName, 
                      dbo.Elen_GoodsInReceived_Sage.BookedDate, dbo.Elen_GoodsInReceived_Sage.Quantity,

                      dbo.Elen_GoodsInReceived_Sage.PONumber, dbo.Elen_GoodsInReceived_Sage.GoodsReference
FROM         dbo.Elen_GoodsInReceived_Sage

Apart from converted fields all others are VARCHAR . Needless to say that individually they work fine..

Can anyone point out what am I missing please?

Answer 1

You have the order of columns in the select statements wrong at one point.

In view1 it is

   dbo.Elen_GoodsInReceived_Winman.Location,     
   dbo.Elen_GoodsInReceived_Winman.TotalValue,

In view2 it is

 dbo.Elen_GoodsInReceived_Sage.TotalValue, 
 dbo.Elen_GoodsInReceived_Sage.Location, 

Change this order to be appropriate.
