Debugging SSIS package is possible using Business Intelligence Development Studio. There are way of debugging the different component of package. Data Flow, Control Flow and Script Task can be debugged using different technique.
Debugging Control Flow: Control flow can be debugged using breakpoints, debugging windows and progress reporting.
Debugging Data Flow: Data Flow can be debugged using data viewer and progress reporting.
Debugging Script Task: Script Task can be debugged using break point in script code. It is same as debugging any .Net code debug.
Apart from above debugging methods you can use different event to write log or send message to know the status of the package execution. Above techniques can only be used while you are executing package using Business Intelligence Development Studio. But if you want to do it on production server (means package which are running out side of development studio), then only way is to generate proper log of you package using package event or adding extra task item in your control flow or data flow.
Next we will see how to use above debugging technique in details in coming blogs.

SSIS Tutorials : First Package
Start SQL Server Business Intelligence Development Studio
BNow your package is ready to run. You run your package using F5 button or using Start Debugging menu item. As this package does not contain anything but still you can run it. Now let see the main components of Package designer.
Any package designer has below main section.
Control Flow: This section contains the main exection work flow of the package. You can define you package execution steps and sequences here. It contains Tasks and Constraints.
Data Flow: This section contains details of Data Flow task like Data Flow Source, Data Flow Transformationa and Data Flow Destination. In short you can read data from source system, apply some trasformation and write back to destination system.
Event Handlers: This section is used to defined the task to be perrformed in case of error or some event like Task Start, Task End, Variable Chaned etc.
Package Explorer: Package explorer gives you the opportunity to see pakage as tree view. It shows all details about package which you see in all other sections.
Execution Result or Progress : This section only appers if you run the packages at least once. Progress section appears while package is running and it changed to Execution Rerult when you stop exection of the package. This section show the details and status of each Task execution.
Apart from above section Package has some more section which are important.
Connection Managers: This section appears only while you are in Control Flow or Event Handler Section. This section shows all connection available to package.
Vaiables: This section shows variable defined at package level or Task level. You can see veriable by Clicking on Variables menu on context menu of Control Flow designer or any Control Flow Item. You can also see variable in Package Explorer section under Variables node.
Aprat from above you can see Property window and Toolbox as you see with any Visual Studio application.
Next we will see how to use different section and details about different Control Flow Items and Data Flow item.

Hello World
Since very long I was thinking to write my blog but I could not start writing probably because of my laziness. Finally today I took a wise decision to write my own blog. I am not sure how long I will continue writing but now I will try to write something on regular basis. If you have come this blog then please do write comment, so that I will motivation to continue writing. You might be thinking that why only today I took this decision. Even I don't know why. So like me don't think and enjoy(!!!) reading my blog.
I think I said enough about reason for starting blog. Now let me tell you what I am gonna write in my blog. From the name (SQL31) you might have guessed that it is something about SQL. You are right, I have some knowledge about SQL which I want to share here. If it is about SQL then what is 31? There is no magic about it. It is my birth day. I was typing some name for my blog and could not find good word so I said let me try this and it was available. That's it. It is SQL31. Good name! Isn't it?
No let me tell you about my self. I am a SQL Server DBA/Developer since 2003. I have worked on SQL server 2000, 2005, 2008, 2008R2, DTS, SSIS, SSAS, SSRS. Apart from SQL server I also have experience of .Net, C#, VB.NET, ASP.Net, ASP MVC, Silverlight, WPF, WCF, XML, HTML, DHTML, Javascript.
That's all for this post. Enjoy the following posts.
