Sunday 20 September 2009

Hi All!...we decided to write some posts on the best practices in writing T-SQL,which we think helpful to the newbies.We will list three best practices each day for the next seven days and hope this series will be helpful to all the readers.So today's best practices tips are,

Document your database

–Use Extended properties of the table structures to document the database.

–Use tools to generate the documentation and correct where necessary

–Maintain the script for populating the extended properties.

Use Cursors only when

–You cannot find a set based solution in 4 Hours

–You want to utilize already existing logic in other SP

–You are writing a database maintenance task

Use STATISTICS IO ON

–This will reduce the logical reads

We need your comments on this post and share the best practices that you are using in the script(related to the above 3 techniques).
