Use script task to dynamically get Excel file as source file connection

  • Hi,

    I was little puzzled to figure out that having for each loop container, it has to be servername property need to be set instead of connection string or any other property 🙂

  • I have a similar issue I am trying to resolve. I have some sample code in vb6 to do this but not sure how to do this in SSIS. If someone can walk me through this please let me know. I have code that looks through a mapped networkrive in a given folder name. The code uses a filesystemobject to find the latest folder creation date using criteria of: beginning foldername isnumeric and the end of folder name = "BOMS" (bill of manufacturing statement). Then the sheet name it needs to import is wb.Worksheets("MBOM"). Then the code imports each excel file and skips any file with the name fullup.xls. Is there an easier way to do this? This process takes 3.25 hours to complete 14 workbooks with approx avg 22k records each!

  • Hi,

    Could you let please tell the version of DTS/SSIS you are using. If you are using SSIS 2005/2008. There lot more easier way to do this. You could avoid more of the scripts. There is one more thing, not sure if excel files are on the server, meaning local to system where SSIS/DTS are running will have little enhancement in execution time. For any case let me know version of ETL you are using.

    Regards,

    Raj

  • how could be the name of excel file is "c:\jenny\" in excel connection manager??? it should be something with the extension ".xls"???

  • mya (9/25/2008)


    Jenny,

    Look at this package. All you need to do is change your database connection,variables and its expression.

    1. change connection to your database

    2. change variables values : SourcePath,Dstpath and FileName(File name can be anything with .xls)

    ConnectionString for your excel file connection manage will be like this

    3. change excel connection manager to

    "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::SourcePath]+ @[User::FileName] +";Extended Properties=\"Excel 8.0;HDR=YES\";"

    4. For loop collection, choose name and extenion only.

    Good Luck.

  • "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @[User::SourcePath]+ @[User::FileName] +";Extended Properties=\"Excel 8.0;HDR=YES\";"

    The excel connection string is overwritten. The above script is set in expressions.

    ya but whn am configuring my excel source and excel connection manager with the above expression am getting an error when i reopen my excel source...

  • Hi Jack,

    I have the same scenario but im using .txt files, i have loaded the files into the table using the foreach loop and i have variable for the filename but im not able to understand how to pick it up and insert its value into the target table. can you give me some direction on that please!!

  • Add a derived column in your dataflow and set it to the value of the variable containing the file name.

    Then map the new column to your database column as usual.
