SSIS event handlers are the simplest means of turning an SSIS script into a reliable system that is auditable, reacts appropriately to error conditions, reports progress and allows instrumentation and monitoring your SSIS packages. They are easy to implement, and provide a great deal of flexibility. Rob Sheldon once again provides the easy, clear introduction.

The most persistent struggle in data processing has been to ensure clean data. There are many ways that data can be incorrect and a database must check, as best it can, that the data is correct. The CHECK constraint is ideally suited for this sort of work, and the checking routine can become quite complex when dealing with check digits in data.

Whilst getting some courseware ready I was playing around writing some code and I decided to very simply show when a window starts and ends based on you asking for a TumblingWindow of n time units in StreamInsight. I thought this was going to be a two second thing but what I found was something I haven’t yet found documented anywhere until now.

Whenever rows or columns are deleted from a table, SQL Server reuses space to accommodate new data. However, this is not the case when a variable length column is deleted. The space used by this type of column is not reclaimed automatically. Variable length columns can be of data types varchar, nvarchar, varchar(max), nvarchar(max), varbinary, varbinary(max), text, ntext, image, sql_variant, and xml. In this tip, I have tried to put forth a solution to reclaim this space and this should work for SQL 2005 and later versions.
