Chapter 6: FILESTREAM with SSIS and SSRSCongratulations! We have successfully completed the first SSIS lab. Execute thepackage and verify that it executes without error and the FILESTREAM columns areupdated correctly.The simplest way to verify that the image files are successfully loaded into theFILESTREAM column is to run the query in Listing 6-18 and look at the size of the BLOBvalue stored in each row.SELECTItemCode,ImageFileName,DATALENGTH(ItemImage) AS FileSizeFROM Items/*ItemCode ImageFileNameFileSize-------- ---------------------- --------1001 C:\Images\IMG_5383.jpg 53033001 C:\Images\IMG_5384.jpg 53444005 C:\Images\IMG_5385.jpg 74896009 C:\Images\IMG_5386.jpg 6470*/Listing 6-18:Verifying that image files are successfully loaded into the FILESTREAM column.You can match the FileSize value returned by the query with the size of the disk file toverify that the image files have been successfully loaded into the FILESTREAM column.We will also cross-verify this in the next lab, where we will perform the reverse operation.We will export the BLOB values from the FILESTREAM column into a series of disk files.Debugging the codeIf you want to debug your code, you can set break points within the code and theexecution will stop there. If your script task has a break point, it will show a red circle inthe designer window as shown in Figure 6-21.254
Chapter 6: FILESTREAM with SSIS and SSRSFigure 6-21:A break point in the Script Task.If you are on a 64-bit computer, you may not be able to debug the package. From theDebugging tab in the properties of the project, you need to change the Run64BitRuntimeproperty to False (Figure 6-22).Figure 6-22:Changing the Debug Options in the project's properties.255
