Identify duplicate indexes

    Hi!

    I hope you can help me out on this one.

    We have identified several indexes on the same columns on several of our tables.

    How should i write a script that lists and/or drops each duplicate index sorted by the index column( or combination of columns)?

    The idea is to create a script to run on production servers at customer sites.

    The way i picture it in my head, the script could automatically drop the first ( of each index combination found) duplicate.

    Is it possible/advisable to create such a script?

    I have played around with some system views, but haven't been able to write the wanted queries yet.

    Please help.

    there's a large number of scripts in the contribution section for this;

    I've used "The Ultimate Duplicate Index Finder" myself;

    take a look here:

    Hi,

    Thanks for the quick reply!

    And thank you once again for your politely telling me to use the search functions of this site:-)

    I think I most likely will find what I'm looking for in one of these scripts.
