		<description><![CDATA[There is definitely a lack of awareness in the SQL world regarding the use of user defined functions and the potential performance hit they can have when using within your queries. Don&#8217;t get me wrong, I would love nothing more than to be able to centralize my commonly used code into functions for reuse. In [...]]]></description>

		<description><![CDATA[The SQL Server Agent by default only keeps 1000 rows of history for all jobs. There is also a limitation for each job to keep only 100 rows each. These rows do not only include the a row for the entire job, but the rows for each step in the job also. These rows can [...]]]></description>

		<description><![CDATA[This command shows the last statement executed for a particular SPID. This statement is mostly used for troubleshooting purposes to determine the exact command a particular SPID is running. You must be a member of the sys admin fixed server role, or have VIEW SERVER STATE permission (if SQL 2005+). As for a real world [...]]]></description>

		<description><![CDATA[This is typically a hot topic and I&#8217;m going to try and tackle it with my rudimentary math. Ultimately given time and the frequency of generation, there is no such thing as a completely unique random number. There will always be some chance that a random number can be regenerated even though the chances do [...]]]></description>

		<description><![CDATA[Anytime we are dividing we need to think of the divide by zero scenario. Even if you think you will never encounter this with your result set, it&#8217;s advisable to guard against it because when divide by zero is encountered, an error is thrown. The best method I&#8217;ve found to overcome this is by using [...]]]></description>
