How to change existing Database Index to Unique

Posted by Akioma on 06-Oct-2015 04:12

Hi all,

we have some Primary indexes in the DB that are not unique, and want to change that.
I assume we cannot simply update the index, so the question is how to achieve this.

My plan is to creat a .df file that deletes the existing index and adds a new index which is unique.
Is this the right solution or are there better ways..?

Any suggestions greatly appreciated!

Thanks,

Mike

There's no way. You have to drop the current index and create a new one.  Just make sure that this new index will hold only unique values.

That's what I feared... :-)

Anyway, thanks for verifying!
