how to effectively modify index
- by daedlus
Hej everyone,
problem : I am looking for right way to convert an index from clustered to non-clustered
Description : I have a table as below in sybase db:
dbo.UserLog
Id | UserId |time | ....
This is hash partitioned using UserId.
Currently it has 2 indexes
UserId : non-clustered
time: clustered
This table has about 20 million records.
I now want to make UserId as clustered index and time as non-clustered index.
is it correct to user alter index to change from clustered to non-clustered
or do i drop index and recreate.
does the fact that userId is used in hash partitioning have any implications to this?
To me alter seems way to go but I have not yet tried this.
