Download the slides and sample code from the Advanced Topics Using Microsoft SQL Server 2005 Integration Services presentation, first presented at the SQLBits 2007 Community Conference. In this session we looked at some of the not so often thought about areas of the SSIS toolbox. Perhaps they aren't considered true ETL by some people or are… Continue reading Advanced Topics in SQL Server 2005 SSIS (Presentation)
Extending SSIS with Custom Tasks (Presentation)
Download the slides and sample code from the Extending SSIS with Custom Tasks presentation, first presented at the SQLBits 2007 Community Conference. The sample demonstrates a custom task with a connection property, including a property grid drop-down (UITypeEditor) to list all your connections and also add new connections, and a password property flagged as sensitive… Continue reading Extending SSIS with Custom Tasks (Presentation)
Multicast Transform and Threading in SQL Server 2008
The Multicast transform in SSIS 2005 enables us to take 1 input dataset and from it generate n output datasets that are an exact copy of the input dataset which is extremely useful at times and we have used it on a number of projects. The downside is that those outputs are synchronous outputs and… Continue reading Multicast Transform and Threading in SQL Server 2008
Meaning of the On Success Workflow Constraint
What do you think happens in the following trivial package (The first task is disabled)? Nothing. Error. Everything except for the first task executes. Let's take a look Suprised? Well if like us you are coming from a DTS background then it most likely will shock you. In DTS this package would not have got… Continue reading Meaning of the On Success Workflow Constraint
Shredding a Recordset
Doing what to a recordset? Shredding a recordset in this instance means that we are going to show you how to take a recordset produced in your SSIS package, loop over the rows in that recordset, break apart the columns and do something with them. This is really useful when you want to preform an… Continue reading Shredding a Recordset
Looping over files with the Foreach Loop
In SQL Server 2000 Data transformation Services (DTS) it was a bit of a hack to be able to loop over files of a given type in a certain directory and import them into your destination. It involved a lot of "Glue Code" and a certain amount of fooling the package into going back to… Continue reading Looping over files with the Foreach Loop
Handling different row types in the same file
Sometimes source systems like to send us text files that are a little out of the ordinary. More and more frequently we are seeing people being sent master and detail or parent and child rows in the same file. Handling this in DTS is painful. In SSIS that changes. In this article we'll take you… Continue reading Handling different row types in the same file
What is Validation?
Some questions keep popping up about validation and I thought I'd try to clarify it a bit. What is Validation I've never seen a good definition for what validation in IS is supposed to be or what it's supposed to do anywhere. There is a lot of discussion about what components do when validating, but… Continue reading What is Validation?
Log Events and Pipeline Events
I was about to write about data flow buffer size configuration properties but need to get this one out first so that we can refer to it. The Data Flow task (internally and in the object model also called the 'Pipeline') logs some pretty interesting information that describe the internal scheduler. To see these messages,… Continue reading Log Events and Pipeline Events
Parallel Execution Properties
Adjusting the following properties can have an impact on parallelization during execution: 1. MaxConcurrentExecutables This is a property on the Package. It defines how many tasks can be run concurrently. A value of -1 means the number of processors and when hyperthreading is turned on, it counts the number of logical processors, not physically present… Continue reading Parallel Execution Properties
