Chapter 6: FILESTREAM with SSIS and SSRSDouble-click the header of the Foreach Loop container to open its configuration dialogbox (Figure 6-14). Then, in the Collection tab, set the following properties:• Enumerator: Foreach ADO Enumerator• ADO object source variable: User::items• Enumeration Mode: Rows in the first table.Figure 6-14:Configuring the properties of the Foreach Loop.This configuration asks the enumerator to loop through all the rows in the first tablecontained in the object variable User::items. We have just configured the Execute SQLtask to assign the result set returned by the stored procedure into this variable, thereforethe Foreach Loop will iterate over the rows returned by the stored procedure.244
Chapter 6: FILESTREAM with SSIS and SSRSFor each iteration of the loop, we will execute the .NET code that loads the image file intothe FILESTREAM column of the Items table. The code that we execute within the loopneeds to know the ItemID of the row currently being processed. This can be achieved bycreating one more user variable, into which the Foreach Loop component can store theItemID value of the current row. You can do this from the Variable Mappings tab of theForeach Loop Editor (Figure 6-15).Figure 6-15:Configuring the Variable Mappings for the Foreach Loop.From the Variable drop-down list, select to create a new variable andmap it to the result set. This opens the Add Variable dialog box again; change the Nameto itemID, the Value type to Int32, and the Value to 0 (Figure 6-16).245
