SQL Saturday 223 OKC

This past weekend I made the relatively short (about 3 hours) trip to the Oklahoma City area to attend and speak at the third annual SQL Saturday event there.  I’ve been invited to speak at each of their three events, and I’ve been impressed with each one of them so far.  The folks in the OKC and surrounding groups have…


Continue Package Execution After Error in SSIS

When it comes to ETL, I’m a pessimist.  Until proven otherwise, I assume that all data is bad, all connections are volatile, and all transformation logic is suspect.  As such, I spent a lot of time addressing how to prepare for and handle errors in the ETL pipeline with SSIS.  Building packages to expect and properly handle errors is a…

Business Intelligence Projects now supported in Visual Studio 2012

Since the release of Visual Studio 2012, business intelligence developers have been limited in how much they could use this tool due to the fact that it did not support BI project types (SSIS, SSAS, and SSRS).  Today, that limitation is now gone with the release by Microsoft of SQL Server Data Tools – Business Intelligence for Visual Studio 2012. …


SSIS Object Variable

Using Object Typed Variables in SSIS

Note: This will be the first post in a short series on using object typed variables (also known as SSIS object variables) in SQL Server Integration Services. When defining variables in SSIS, the ETL developer has several data type options to choose from depending on the information to be stored in each variable.  Included in the options are String, Boolean,…
