I guess it doesn't work on SQL 2000 (which is what I am using)?


Sorry, MSSQL 2005 and higher

Hi,

Thanks. I removed those empty spaces.. !! Its "completed" successfully.

However its turned out as 100% successfull, I can possibly run the view and its turns out as nothing. And I run across the same procedure into few DB's.

This view will only work in the database the view is created:
and        a.database_id = DB_ID()            -- for current database only


(that's the only thing which comes into my mind, or there are no indexes in the database :-D )

Try cutting this view into smaller pieces, for example first query the dm_ view, add join on sysindexes etc.

Wilfred,

What is the purpose of this elaborate query?

(NOTE: I have commented out the ALTER INDEX (DISABLE) statement until I get an explanation of what the query is supposed to do.)

I've run it against several test databases using SS2005 and SS2008. Without the ALTER INDEX (DISABLE) clause enabled, it appears to do nothing.

If I may, that line is to create the command to disable an index. It looks to be purely optional and is only the text of the command. The command would need to be copied and executed separately.

It's an easy way to disable a low performing index, by copy/paste this disable statement

I have taken this script provided by Wilfred and updated it to SQL 2005.
