String or binary data would be truncated. The statement has been terminated

Question

I have met some problem with the SQL server, this is the function I created:

ALTER FUNCTION [dbo].[testing1](@price int)
RETURNS @trackingItems1 TABLE (
   i         


        

Answer 1

Specify a size for the item and warehouse like in the [dbo].[testing1] FUNCTION

@trackingItems1 TABLE (
item       nvarchar(25)  NULL, -- 25 OR equal size of your item column
warehouse   nvarchar(25) NULL, -- same as above
price int   NULL

) 

Since in MSSQL only saying only nvarchar is equal to nvarchar(1) hence the values of the column from the stock table are truncated
