ForEach Loop Container Mapping Variable From SSIS Package Not Working In SQL Server stored procedure

Question

I have a SSIS package that uses a ForEach Loop Container to enumerate Excel files in a dir. I also have a Task Flow that inserts data from those Excel files into SQL Server.

I'm trying to insert the file names into a column into the same table in SQL Server by using a mapping variable in my stored procedure.

I'm having trouble with my MappingVariable at the end of the script with red squigglies. The following is my stored procedure script.

CREATE PROCEDURE [dbo].[Insert_F_STG_v2]
    @Hrs float,
    @Type nvarchar(100),
    @SN nvarchar(100),
    @Op nvarchar(100),
    @[USER::CurrentFileName]  
AS
BEGIN
    SET NOCOUNT ON;

    INSERT INTO [CRM_RC].[dbo].[F_StgTbl]([Hrs], [Type], [SN], [Op], [Report_Date])
    VALUES (@Hrs, @Type, @SN, @Op, @[USER::CurrentFileName])
END

The last @[USER::CurrentFileName] in the values block at the bottom of the script is the one giving me issues.

The following is the error:

Msg 102, Level 15, State 1, Procedure Insert_F_STG_v2, Line 95
Incorrect syntax near 'USER::CurrentFileName'.

Answer 1

You need to add a derived column to your data flow, and assign User::CurrentFileName to the new column, then include this new column in your column mapping.

In your stored procedure, change @[USER::CurrentFileName] to a proper SQL type such as @filename nvarchar(255).

Suggestion: You could also do away with the stored procedure, and insert directly into the table (would be faster, since its bulk inserted) by using a SQL destination instead of Executing a procedure for every row.

Answer 2

@[USER::CurrentFileName] is not a valid parameter name, and you don't have datatype assigned to it. SQL Server is treating [USER::CurrentFileName] as a datatype and therefore failing.

In the end it appears you are trying to insert that value into [Report_Date] column. Which I'm not sure how Date and Filename would be compatible.

Answer 3

What you need to do is create as second Variable that parses the useful information out of your file name. In a separate variable parse the date from @[USER::CurrentFileName] then use that Variable in this proc. I would be more specific but I don't know how your file is named.
