This script uses two undocumented stored procedures that retrieve all tables in the database in which it is run and lists the data and index sizes, the sum of these sizes, and the table's size percentage of the entire database. The results are presented in descending order of the sum of the data and index size.
Simply run this in Query Analyzer in the database you want to query.
Another script from DOS but shows alerts
Like the one posted before, the use of the SP is like this: proc_alerts 1,18. This will show the first 18 alerts on the system. OR proc_alerts 20,35 will show from 20 to 35. This lets you manage the list without letting go out of the screen.
