Calling user-defined functions in OLE DB Command transformation

Hi

We have a user-defined function that can be called directly via SQL (in SQL Server Management Studio) without error. We would like to use this function to populate a column, whist data is being processed within Integration Services. Using an OLE DB Command transformation to achieve this would seem the most appropriate.

The following was inserted for the SQLCommand property:

EXEC ? = dbo.GetOrderlineStatus(@.dt_required = ?, @.dt_invoice = ?, @.dt_despatch = ?, @.ch_status = ?, @.si_suffix = ?, @.re_quantity = ?, @.vc_invoice_id = ?, @.vc_order_id = ?)

However, when the Refresh button is pressed we are presented with the error below:

Error at Load Orderline [OLE DB Command [15171]]: An OLE DB error has occurred. Error code: 0x8004E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x8004E14 Description: "Invalid parameter number".

If we use SET instead of EXEC (e.g. SET ? = dbo.GetOrderlineStatus(@.dt_required = ?, @.dt_invoice = ?, @.dt_despatch = ?, @.ch_status = ?, @.si_suffix = ?, @.re_quantity = ?, @.vc_invoice_id = ?, @.vc_order_id = ?)) the following error is produced:

Error at Load Orderline [OLE DB Command [15171]]: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Syntax error, permission violation, or other nonspecific error".

Any assistance would be greatly appreciated.

Thanks

You cannot use SET or EXEC with a UDF. You need to use

SELECT @.ReturnVar = [dbo].fnYourFunctionName ( @.InputVar )
