SQL-Articles » SPARSE Column

published 505 days, 9 hours, 46 minutes ago posted by

sqlarticles 505 days, 13 hours, 55 minutes ago

It’s been a long this feature has been released however I just got an opportunity to check it out. This feature is released in SQL Server 2008 version. Sparse columns are normal columns which will store NULL values in a optimized storage which means no storage space is taken when you store NULL values to that column. Happy !! there is some overhead for storing non NULL values to this columns, it will take some more space for non NULL values. (more)

IIF function is new to SQL Server Denali however if you worked with MS Access then you are familiar with this function. So if you are upgrading a database from Access to SQL Server Denali you don’t need to worry about rewriting the IIF function queries. IIF function will evaluate the expression and it will return one value out of two input values.

SQL-Articles >> Day 14–Trace Flag 3505–Control SQL Server Checkpoint Behavior Read more: http://sql-articles.com/articles/general/day-14trace-flag-3505control-sql-server-checkpoint-behavior

posted by

sqlarticles 625 days, 21 hours, 51 minutes ago

What’s is checkpoint? Checkpoint is a process which will write all dirty pages (modified page in buffer cache which is not written to disk) from buffer cache to disk. It helps in recovery time of the database so that when the database start’s up there is no need to do this for all dirty pages, so checkpoint happens in an regular interval. For more information on checkpoint refer the KB article http://msdn.microsoft.com/en-us/library/ms188748.aspx. Read more: http://sql-articles.com/articles/general/day-... (more)
