  • It’s Data Tier Application and Data Application Component

    OK – In SQL Server 2008 R2 we did “re-use” an acronym or two (DAC and DTA), but it’s important to remember there are actually two parts to this new feature. One is the Data Application Component (DAC) and the other is the Data Tier Application (DTA). The DAC is the file created for a DTA. In SQL Server 2008R2 and Visual Studio you’ll find there ...

  • Monitoring SQL Azure For Performance

    In SQL Server Azure, there are no Dynamic Management Views (DMVs) or Performance Monitor Objects and Counters that you can access, so you can’t run your standard performance monitoring that way. I suspect that as time goes on, SQL Azure will have some instrumentation, but for the time being, you’ll have to go with a different metric – round trip ...

  • After the Upgrade, it runs differently…

    I got a question yesterday in the mail that I thought I would just answer here in a broad context. While I can’t troubleshoot or do performance tuning from a distance, there are some interesting concepts and suggestions this e-mail brings up: “I have recently seen a change from SQL Server from 2005 to 2008 in where it handles CASE statements ...

  • Aren’t DBA’s Just System Admins for Databases?

    Last week I ran into an argument I’ve had since I left the mainframe space decades ago. A developer told me “DBA’s don’t design databases.” The inference was that DBA’s (i.e., Database Administrators) only worry about hardware, security, OS, database backups, things like that. He seemed amazed that a DBA would ever do “data” work. It may be the ...

  • Code that Writes Code

    I have scripts that re-create my databases for testing and development purposes. But sometimes I want to take the data from a set of tables and move it as well – I could use SSIS, or a SELECT INTO statement, but what if I want to “re-set” the data to a point in time? In other words, load it with some “base data”? I thought this might be a good ...

  • Changing the Primary Key After You Have Data

    Yesterday I blogged about changing a Primary Key (PK) during the design phase, and before you have data in the database. Even then, it’s not trivial to change the data type or column(s) that make(s) up the PK. When you have data in that Primary Key and/or you have Foreign Keys (FK) that point to a PK field, this becomes a much more involved ...

  • "Cloning" Symmetric Keys

    It's well-known by now that SQL Server 2005 and 2008 include new encryption-related statements that allow you to create and administer encryption keys. You can use CREATE CERTIFICATE to create or import a certificate or DROP ASYMMETRIC KEY to remove an asymmetric key from the database, for instance.  One of the interesting ommissions ...
