Data Warehouse from the Ground Up at SQL Saturday Orlando, FL on Oct. 10th

SQL Saturday #442SQL Saturday #442 is upon us and yours truly will be presenting in Orlando, Florida on October 10th alongside Mitchell Pearson (b|t). The session is scheduled at 10:35 AM and will last until 11:35 AM. I’m very excited to be presenting at SQL Saturday Orlando this year as it’ll be my first presenting this session in person and my first time speaking at SQL Saturday Orlando! If you haven’t registered yet for this event, you need to do that. This event will be top notch!

My session is called Designing a Data Warehouse from the Ground Up. What if you could approach any business process in your organization and quickly design an effective and optimal dimensional model using a standardized step-by-step method? In this session I’ll discuss the steps required to design a unified dimensional model that is optimized for reporting and follows widely accepted best practices. We’ll also discuss how the design of our dimensional model affects a SQL Server Analysis Services solution and how the choices we make during the data warehouse design phase can make or break our SSAS cubes. You may remember that I did this session a while back for Pragmatic Works via webinar. I’ll be doing the same session at SQL Saturday Orlando but on-prem! ;)

So get signed up for this event now! It’s only 11 days away!

Create Date Dimension with Fiscal and Time

Here are three scripts that create and Date and Time Dimension and can add the fiscal columns too. First run the Dim Date script first to create the DimDate table. Make sure you change the start date and end date on the script to your preference. Then run the add Fiscal Dates scripts to add the fiscal columns. Make sure you alter the Fiscal script to set the date offset amount. The comments in the script will help you with this.

This zip file contains three SQL scripts.

Create Dim Date

Create Dim Time

Add Fiscal Dates

These will create a Date Dimension table and allow you to run the add fiscal script to add the fiscal columns if you desire. The Create Dim Time will create a time dimension with every second of the day for those that need actual time analysis of your data.

Make sure you set the start date and end date in the create dim date script. Set the dateoffset in the fiscal script.

The new SSIS connectors for Oracle and Teradata are available now.

FYI the 2.0 version is for 2012 only… You want the 1.2 version for 2008

---Thanks to Mike Davis & Devin Knight for the info!

Using the Microsoft Connector for Oracle by Attunity with SQL Server 2008 Integration Services



I was recently tasked with creating a test package to check the performance of SSIS loading data from MS SQL Server 2008 to an Oracle database and loading data from Oracle to MS SQL Server.

My tests have only been performed on a 32bit laptop running Windows XP (Yeah, I know...)

Here are the steps I took:

  1. Install Oracle Developer Suite 10g ( (including Forms and Designer)  (for 64 bit test, you would just need to install the 64 bit version.)
  2. Edit C:\DevSuiteHome_1\NETWORK\ADMIN\TNSNAMES.ORA by appending the TNS information provided by your Oracle DBA.
  3. Edit C:\WINDOWS\system32\drivers\etc\hosts using notepad.  Add the host entries provided by your Oracle DBA to the file.
  4. Create a new SSIS package, add a connection manager of type Native OLE DB\Microsoft OLE DB Provider for Oracle.  Enter SOMETEXT (see example TNS Entry below) in Server name, and the user name and password provided.  Click Test Connection.
  5. Create an Execute SQL Task to truncate the Oracle table you will be loading.  Must be coded like this:  truncate table "SOME_TEST"."Movies"    **NOTE: SOME_TEST is the schema name.
  6. Create another Execute SQL Task to truncate a SQL Server table called Movies2.
  7. Create a data flow to pull data from SQL Server to Oracle.
  8. Create a data flow to pull that data from Oracle into another new table in SQL Server (Movies2).
  9. Data Types are tricky.  You may have to cast as nvarchar or numeric(38,0) when pulling from SQL Server and use derived column transformations when pulling from Oracle.
  10. For the Oracle Source & Destination components, right click and select Show Advanced Editor.  Under component properties, set AlwaysUseDefaultCodePage to True.


Now comes the fun part...
Using the Oracle Connection managers that come w/ SQL Server, it took approximately 10 minutes 45 seconds to pull about 45,000 rows of 2 columns full circle.   (That is slow!)
My good buddy, Stephen Bowley, told me about the Attunity drivers that you can download from Microsoft's website.

These drivers only took 45 seconds to complete the same task.  It creates new data flow components specifically for Oracle source and Oracle destination (similar to the OLE DB Source / Destination components; but, specifically for Oracle.)


ExSample TNS Entry: 






    (LOAD_BALANCE = yes)







Example Hosts entry:     SOMESERVERA   SOMESERVERB


The following are the instructions my buddy Stephen sent me.  I didn't have to follow these b/c my test was only done on a 32 bit laptop.  I think he was developing on a 64bit environment.  I will post them here in the event they might help someone else.


If server is 64bit, Then we have to install both the 

32bit and 64bit drivers for the attunity connector utility. 

Can be found at:

Once installed, you'll have to installed the correct Oracle Client tools. 

This also requires you install the 32bit and 64bit versions. 

next you have to setup the Service Names on the DB box through oracle

using the Oracle Net Manager application. This has to be done for both 

32bit and 64bit installations. Name the service names the same. Remember

these are where you use the connection information of the oracle server.

Make sure you can connect to the Oracle instance on server

through the SQL-Plus untility.

You'll probably have to create a new folder called "ProgramFilesx86" on the root of installation path of SQL Server.

Then COPY everything from the "Microsoft Visual Studio 9.0" folder in that. THEN ALL BIDS shortcuts needs to ref

that direcory otherwise the connector wont allow BIDS to manually run the package since BIDS is a 32 BIT application.

Funny quote:

"I do not expect that Microsoft will write an Oracle fast loader - currently it comes in around number 999 in my list of 1000 features for next version, just slightly ahead of recompiling for Linux." - Donald Farmer
