For my requirement I need to write Script task from One SSIS package to another. As my server is 64bit machine, when I execute the overriden SSIS package, it throws the error "Binary Script not found". Hence I need to compile the script programmatically in the Parent SSIS package and put the binary code into the another one. I dont know how to compile the Script programmatically.
Let me know how to do that
I don't think you can do this with SSIS. If there's a way to accomplish this using a Parent Package / Child Package architecture, I'm unaware of it.
You can get more flexibility creating packages dynamically in .Net. Although I haven't tried to dynamically compile script task code.
I'm curious: Why not copy the code out of the parent package and paste it into a child package?

So you need to somehow programatically execute a (Debug>Build). This typically gets around the problem of binary not being found, when you do it manually in VS. Doesn't strike me as possible at runtime though.

I am using SSIS for ETL and I need to monitor a source folder for the source file to be arrived. When ever a file arrives I need to move that file into another location and rename the file and start executing another SSIS Package. Here we don't have an option to use use any other tool to automate the execution. We have only choice to use SQL Server, SSIS.
I need the mechanism and the logic to implement this logic.
I'm assuming that by "File Watcher" you don't mean FileSystemWatcher class in .NET, as there wouldn't be any point in using this class if you're limited to SQL Server and SSIS (you'd need a job with forever-running SSIS package containing ScriptTask with FileSystemWatcher).
The only solution is to create two-step job. First step would contain SSIS package for reading directory content and comparing it to files history log. Second step would contain your main package and would execute only if first steps succeeds or returns value indicating that there are new files to process.
Your answer is here and here. My personal favorite way of doing it is having an infinite loop package. Yet another way of doing it would be to encapsulate the entire logic in an SSIS package and fire it every X minutes. Vary the value of X depending on the urgency.
I am trying to zip excel files using SSIS Process Task. This task asks for Executable. Unfortunately on the machine where I am executing SSIS, does not have any 3rd party provided compression utility. All I have is Windows built in compressor. I want to know how this can be used as executable and zip my files.
Thank you for your time.
You could use 7zip's command line version without installing it.

Also, if your excel files are outputed as '.xlsx' they are already compressed. This is also true for any other office type that ends in an 'x'. Try changing the extension to '.zip' and open them.
Edit: Depending on how much you're doing you might want to consider buying the Cozyroc package which includes a zip task as well as many other useful ones. Not too costly either.

I just want to add this note about cozyroc
You can test and develop with the SSIS+ components for as long as needed to determine if the components are suitable for your needs.
When you run the SSIS package from the command line with DTEXEC or SQL Server Agent, the license verification code is activated.
If a license is not found, the package execution will fail, the first time it tries to use SSIS+ library component.
Is it possible to redirect the Exceptions occurred to another table/log, in Script Task ? If so, How is it to be done ?
You can do anything in a script task that you can do in vb.net or C#. But if you are doing so much in a script task, why do you need to use SSIS. SSIS handles most things like exception logging, error handling, etc fairly well. You should use SSIS for what it does and only sparingly go to a script task when you are trying to do something specific that SSIS does not handle well. To have an SSIS package that simply has a Script Task in it that handles everything, would be like having a vb.net program that calls a C# dll for all of the work. If you wrote everything in C# why would you need the vb.net wrapper?
In VB pseudocode, I'm trying to accomplish the following using SSIS (either 2008 or 2005)
If FileHasAlreadyBeenDownloaded = False Then
DownloadTheFileFromFTP
End If
ImportTheDownloadedFile
To do this in SSIS I have a script task to check for the file, and if it exists it transfers directly to the DataFlow Task using conditional expressions. If the file doesn't exist, it transfers to the FTP Task, and the FTP Task transfers to the DataFlow Task.
It seems, though, that I can't have two tasks lead into one common shared task, because no matter which path the code takes it won't execute the DataFlow Task. If I make a copy of the DataFlow task and have each path go to its own Task, then all works perfectly.
Is this a documented thing with SSMS that I just haven't found? I looked through 31 pages of questions on SSMS before posting, so hopefully this isn't a stupid question.
I also tried using Expressions on the FTP task to set "Disabled=#FileAlreadyDownloaded=True" but that works only in SSMS 2008 and didn't seem to work in SSMS 2005.
Thanks so much for any pointers on this!
It might be worth trying putting the script task and the FTP task inside a container task, and link the the container to the data flow task on success.
I'm trying to programmatically add an Execute SQL task from within a script task of my SSIS package. I know that the Microsoft.SqlServer.Dts.Runtime.Package class has an Executables collection which I can add my new task to but how to I get a reference to the package Im inside of?
It is not possible, SSIS does not support self-modifying packages.
To prevent any attempts of doing what you are trying to do, the task code does not have access to the package API, so you can't obtain reference to Package object from a task. But even if you find a way to curcumvent this - the results are not predictable, as package is not allowed to modify itself at runtime.
If you could describe what you really want to achieve (rather than asking for particular way to do it) - someone might find a way to do it. Maybe you can use child package - it is OK to modify child package before its execution, or maybe it is enough to just change some variables that are used by Execute SQL task later in this package?
As Michael says above, it's not possible to do what you are asking. However, you may be able to find a solution by setting variables at runtime, or by enabling or disabling certain packages at runtime using dtexec. For example:
dtexec /f e:\ssis\master.dtsx /set \Package\YourPackageName.Disable;True
