How to cast variables in T-SQL for bulk insert?

Question

The following code gives an error (its part of a T-SQL stored procedure):

-- Bulk insert data from the .csv file into the staging table.
DECLARE @CSVfile nva         


        

Answer 1

As I know only literal string is required in the from. In that case you have to write a dynamic query to use bulk insert

declare @q nvarchar(MAX);
set @q=
    'BULK INSERT [TStagingTable]
    FROM '+char(39)+@CSVfile+char(39)+'
    WITH
    (
    FIELDTERMINATOR = '','',
    ROWTERMINATOR = ''\n'',
    FIRSTROW = 1  
    )'
exec(@q)
