SQL Server Stored Procedure with a FileName variable

Question

I am having some serious problems with loading data from xml file. I want to declare it as a procedure with the .xml file name as parameter.

GO
ALTER PROCEDURE loadXML 
@FileName varchar(50)
AS
 BEGIN 
    DECLARE @XML AS XML,@hDoc AS INT
    SELECT @XML = CONVERT(XML, BulkColumn) 
    FROM OPENROWSET(BULK 'D:\ '+@FileName , SINGLE_BLOB) AS x;

    EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML

    INSERT  INTO [dbo].[Client]
    SELECT *
    FROM OPENXML(@hDoc, 'orderType/client')

    WITH
    (
         OrderId varchar(200) '../../../sn',
         Client_number varchar(200) 'client_number',
         FirstName varchar(200) 'firstname', 
         LastName varchar(200) 'lastname', 
         E-Mail varchar(200) 'email'   
    )

   EXEC sp_xml_removedocument @hDoc   

END

exec loadXML 'order2.xml'

Obviously, this code won't work, because there's a syntax error near the @FilePath variable. I tried making string variables with the whole SELECT part, but it didn't work.

Answer 1

Why don't pass the entire path along with drive name as parameter. I mean D:\folder1\file.xml.

Assuming that @FileName parameter has the full path like D:\folder1\file.xml then you can use dynamic query to achieve what you are looking for like below. Give it a try

DECLARE @sqlCommand varchar(1000)
SET @sqlCommand = 'set @XML = (SELECT '+ @XML + ' = CONVERT(XML, BulkColumn) 
    FROM OPENROWSET(BULK ' + @FileName +' , SINGLE_BLOB) AS x)';

declare @xml xml;

EXEC sp_executesql @sqlCommand, N'@XYZ xml output', @xml output


EXEC sp_xml_preparedocument @hDoc OUTPUT, @XYZ;
