I have wasted most of this afternoon with a dumb problem. I was testing some regular expressions, but for some reason the script task was not letting me break, so I create an SSIS variable (SSIS 2012) and made it read-write and assigned the value. I then put a break on the PostExecute event. I viewed […]

Here is an annoying problem. You are dealing with dozens of SQL Server databases and you are looking for a particular table in one of the databases. How can you find the table? Do you click through all of the databases to find the one that houses that table? Here is a simple query to find a

There is a little warning in books-on-line about the interaction of Deny and Grant (http://msdn.microsoft.com/en-us/library/ms173724.aspx). “A table-level DENY does not take precedence over a column-level GRANT. This inconsistency in the permissions hierarchy has been preserved for backward compatibility.” However, I found a little caveat to this point. The order in which you issue the GRANT and

“cross join” is a difficult to explain to trainees. The mechanics aren’t very complicated. However, the question is where you would ever use them? One example that I came up with is generating a calendar. Let’s say I want to generate a list of dates in a set of years. For example, I want a

There has been a basic method from SSIS 2005 for creating an SSIS package template. You create package, then put that package into a magical folder (under the Common7 folder of the appropriate version of Visual Studio), and voila you have a package template (see http://www.mssqltips.com/sqlservertip/2841/creating-ssis-package-templates-for-reusability for the full process). A major problem with this process has been

One of the things that I like about providing training is the kind of questions that come up. Many times they are issues that I have thought about but been just plain too lazy to examine. This week one of my students asked if it were possible to lookup at record in another table and

I have been meaning to write my thoughts about SQL Server for a while. I hope my thoughts will help others with their SSIS and SQL questions as well as to help me to learn from writing as well as from the input of others. I am preparing for a very exciting week of SQL
