More value from your data through data mining (Presentation)

by Allan Mitchell 25 Sep 2008 11:35
In this Live Meeting presentation Allan looks at data mining. The presentation is split evenly between demos and talking. Allan will give a brief overview of what data mining is along with some of the terminology as well as looking at what is available to you using SQL Server 2005. For the demos he uses Excel 2007 and the Data Mining add-in to demonstrate how even the least statistically minded of us can get started with this technology Presentation

SQL Server Editions and Integration Services

by Darren Green 24 Sep 2008 14:00
The SQL Server 2005 and SQL Server 2008 product family has quite a few editions now, so what does this mean for SQL Server Integration Services? Starting from the bottom we have the free edition known as Express, and the entry level Workgroup edition, as well as the new Web edition. None of these three include the full SSIS product, but they do all include the SQL Server Import and Export Wizard, with access to basic data sources but nothing more, so for simple loading and extraction of data this should suffice. You will not be able to build packages though, this is just a one shot deal a... [More]

Download the slides and sample code from my Extending SSIS with custom Data Flow components presentation, first presented at the SQLBits II (The SQL) Community Conference. Abstract Get some real-world insights into developing data flow components for SSIS. This starts with an introduction to the data flow pipeline engine, and explains the real differences between adapters and the three sub-types of transformation. Understanding how the different types of component behave and manage data is key to writing components of your own, and probably should but be required knowledge for anyone bu... [More]

Advanced Topics in SQL Server 2005 SSIS (Presentation)

by Allan Mitchell 15 Oct 2007 14:00
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 simply not seen but we think they are really useful weapons in our ETL armoury. Highlights include: Loading partitions directly Consuming a package in SSRS Using a DM algorithm in the pipeline to see... [More]

Extending SSIS with Custom Tasks (Presentation)

by Darren Green 13 Oct 2007 14:00
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 to honour the package protection level. It also illustrates how to create a user interface for your task. Abstract This session is all about developing for SSIS, writing .Net code to create your own tasks. We cover b... [More]

Multicast Transform and Threading in SQL Server 2008

by Allan Mitchell 19 Sep 2007 14:00
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 therefore are on the exact same thread as the input dataset. Normally a Synchronous output is good as no memory has to swap buffers and it is exceptionally quick. A problem arises if we have on one or more of those outputs a blocking Asynchronous transform. When this happens processing of the other ou... [More]

Pipeline Memory Limiter

by Allan Mitchell 10 Sep 2007 14:00
Michael Entin has blogged about something that you see now, well you feel the effects anyway, in SQL Server 2005 but it isn't as visible as it should be but is really important. Backpressure is an interesting internal memory limiter inside SSIS and in SQL Server 2008 you get to see when the limiter kicks in. For a detailed explanation see Michael''s blog entry here but we wanted to show you how to reproduce it very simply. Here is a package we are going to use to show the limiter kick in and how SQL Server 2008 shows us it taking effect: Inside the Script Component a... [More]

Where To Find Integration Services Packages in SQL Server

by Allan Mitchell 27 Aug 2007 14:00
We see this coming up quite a bit on newsgroups and even have people eMailing about it so we though we would put up an article explaining where to find packages when saved to SQL Server. If you want to view them visually in SQL Server Management Studio then you will need to connect to the Integration Services Service for the Server on which you have stored the packages. Below is an example of us connecting to the service by first opening up Object Explorer and then connecting to the Service by choosing it from the dropdown menu and then using Integrated security (no choice here) to...

Script Task Breakpoints in SQL Server 2008

by Allan Mitchell 23 Aug 2007 14:00
One of the things coming from our look at SQL Server 2008 Integration Services is that you are not going to see a lot of change visually. What you are going to see is things going on underneath the covers that makes SSIS perform better, and improved informational messages from the components. Just such a change is seen in the Script task. In SQL Server 2005 we drop onto the designer two Script tasks and join them with workflow. We can then go into the Scripts of the tasks and set breakpoints in the code of each. The Control Flow should now look something like this.   &... [More]

The Execute SQL Task

by Allan Mitchell 9 Oct 2005 14:00
In this article we are going to take you through the Execute SQL Task in SQL Server Integration Services for SQL Server 2005 (although it appies just as well to SQL Server 2008).  We will be covering all the essentials that you will need to know to effectively use this task and make it as flexible as possible. The things we will be looking at are as follows: A tour of the Task. The properties of the Task. After looking at these introductory topics we will then get into some examples. The examples will show different types of usage for the task: Returning a single value from a SQL q... [More]

Comparing Overhead on the Execution Methods

by Allan Mitchell 7 Oct 2005 14:00
So we got to playing with some of the ways that you can execute an SSIS package and got kind of curious about any overhead associated with the execution methods. From these thoughts came a few tests and here are our findings. We decided to look at performance over two different pipelines. We also had to decide on a "Control" so that we had something against which to measure. In the tests the "Control" was achieved by executing each pipeline in the Business Intelligence Development Studio with debugging (F5). Pipeline 1 This pipeline is a straight Source ... [More]

Meaning of the On Success Workflow Constraint

by Allan Mitchell 3 Oct 2005 14:00
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 off first base. Explanation Follows: The meaning of the On Success Constraint should not be read as such. It should be read as No Errors Occured. If the task does not execute i.e. if it is disabled then the TaskHost posts a result of No Err... [More]

Shredding a Recordset

by Allan Mitchell 15 Jun 2005 14:00
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 action on a row of data for every row of data just like we are going to do here. Sure we could use an ExecuteSQL task to get the recordset as well but that does limit our choices of source data whereas doing it in the pipeline does not. Something useful we hope. Retrieving the Recordset There ... [More]
