Very frequently I have been asked to create a page, post or article where in one page all the important concepts of SQL Server are covered. SQL Server 2008 is very large subject and can not be even covered 1000 of pages. In daily life of DBA there are few commands very frequently used and for novice developers it is good to keep all the important SQL Script and SQL Statements handy.
I have attempted to create cheat sheet for SQL Server 2008 most important commands. User can print this in one A4 size page and keep along with them. This can be used in interviews where T-SQL scripts are being asked.
