Database compatibility level, what happens after upgrade

Filed under: SQL Server Database — Tags: , , , , , , — Shahfaisal @ 8:04 pm

What is Database compatibility level?
The database compatibility level determines how certain database behaviors work. During the upgrade process(in-place upgrade) to SQL Server 2008, a database will retain its existing compatibility level if the compatibility level is greater than or equal to 80; otherwise, Setup will automatically set the compatibility level to 80.
Note: However, the System Databases will have the compatibility level of 100 when upgraded to 2008.

How can we change the Database compatibility level?
Right-click the database, and then click Properties. Go to options and the compatibility level is displayed in the Compatibility level list box.
