Question : T-SQL Union

The query Below has no Syntax error but it is not returning what I need

I am having a problem with the SalesPrice Column

This Statement returns a column with 0's pre filled: OK thats fine thats what I need since this column does not exist in the table
SELECT Territory, CustomerNo, ProductLine, ItemCode, p.List, CAST( 0 AS INT) AS SalesPrice FROM dbo.Tmp_Actual

This statement returns value 2010. This is not what I want
SELECT Territory, CustomerNo, ProductLine, ItemCode, List, 2010_Sales_Price FROM dbo.Tmp_Forecast F

in this table there are values I want to return back from the table..

I created a dummy column on the first query because its a union and Columns must be equal. But I must be doing something wrong if its not letting me return the values that are in Forecast...

How can I combine both and have SalesPrice Return is true value instead of 2010

thanks!

Answer : T-SQL Union

You can try using UNION ALL instead which will treat the values separately. If you can have duplicates within each of the queries just add back DISTINCT keyword there so you will get unique from each, but duplicates when appearing in both.

SELECT DISTINCT Territory, CustomerNo, ProductLine, ItemCode, p.List, CAST( 0 AS INT) AS SalesPrice FROM dbo.Tmp_Actual A inner Join P on A.ItemCode = P.ItemNumber and p.rn=1
UNION ALL
SELECT DISTINCT Territory, CustomerNo, ProductLine, ItemCode, List, 2010_Sales_Price FROM dbo.Tmp_Forecast F inner join Product Pd on F.ItemCode = Pd.ItemNumber and pd.Quarter = 2010100
