sql - Bulk insert using stored procedure

Question

I have a query which is working fine:

BULK INSERT ZIPCodes 
FROM  'e:5-digit Commercial.csv' 
WITH 
( 
     FIRSTROW = 2 ,
    FIELDTERMINATOR = ',', 
    ROWTERMINATOR = '
' 
)

but now I want to create a stored procedure for it.

I have written below code to make its stored procedure:

create proc dbo.InsertZipCode
@filepath varchar(500)='e:5-digit Commercial.csv'
as
begin
BULK INSERT ZIPCodes 
FROM  @filepath 
WITH 
( 
     FIRSTROW = 2 ,
    FIELDTERMINATOR = ',', 
    ROWTERMINATOR = '
' 
)
end

but its showing error:

Msg 102, Level 15, State 1, Procedure InsertZipCode, Line 6 Incorrect syntax near '@filepath'.

Msg 319, Level 15, State 1, Procedure InsertZipCode, Line 7 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon.

Please tell me what I am doing wrong and what I can do to make it work in stored procedure.

Thanks

There's nothing wrong with your stored procedure code - the point is: the BULK INSERT command cannot accept a file name as a variable.

This does work:

BULK INSERT ZIPCodes 
FROM  'e:5-digit Commercial.csv' 
WITH 

but this never works - within a stored proc or not:

DECLARE @filename VARCHAR(255)
SET @filename = 'e:5-digit Commercial.csv' 

BULK INSERT ZIPCodes 
FROM @filename
WITH 

So you just cannot do it this way, unfortunately. You could consider building up your BULK INSERT statement as a string (with a fixed file name) and then execute it as dynamic SQL - but I don't really see any other solution.

DECLARE @filepath nvarchar(500)
SET @filepath = N'e:5-digit Commercial.csv'

DECLARE @bulkinsert NVARCHAR(2000)

SET @bulkinsert = 
       N'BULK INSERT ZIPCodes FROM ''' + 
       @filepath + 
       N''' WITH (FIRSTROW = 2, FIELDTERMINATOR = '','', ROWTERMINATOR = ''
'')'

EXEC sp_executesql @bulkinsert
