When SQL Server is installed, the “tempdb” database is placed by default, on the same drive that SQL Server is installed on.
As this is usually the same drive as the operating system, it is best to move the “tempdb” database to a separate drive.
Whilst studying for my MCITP Database Developer certification, I have come across a very useful function that returns the value of the first non-NULL value from multiple choices
The default value of a parameter can be specified as NULL. In this case, if you do not supply a parameter, SQL Server executes the stored procedure according to its other statements. No error message is displayed.
The procedure definition can also specify that some other action be taken if you do not give a parameter.
