Hello,
I want to load data from Staging to Development environment.
In Dev. environment , I have index that is use for stored procedure and Staging environment, I don't have index.
Now My Question is ,
Do I need to disable Index while loading data from Dev to staging ?
Which index, Clustered or Nor clustered ?
If I have 5 Non-clustered Index and 1 clustered Index in a table, Can i disable 5 Non clustered Index by common Script. This Non-clustered Index might change in future So I don't want to hardcore their name while disabling.
How can I Rebuild 5 Non clustered Index for Table ?
Thanks
Bhavesh

I'm not sure which direction you are trying to go.

As per the question regarding whether to disable or not, it depends on your environment. You should test it with both dropping and with not dropping the index.

As per the rebuild question - the syntax is

Alter Index index_name on table_name REBUILD

It is actually impossible to speak with any certainty because you didn't post any details about the tables. I suspect you are probably fine because unless the missing index is a unique index you should be ok. Again, this is pure speculation based on LOTS of assumptions.

Have you tried it? Did you make a backup first?

>> Do I need to disable Index while loading data from Dev to staging ? <<

Can't say for sure without more details, but if it is a large % of the total rows of the table, it can speed up the inserts.

>> Which index, Clustered or Nor clustered ? <<

You should disable only non-clustered indexes.

>> If I have 5 Non-clustered Index and 1 clustered Index in a table, Can i disable 5 Non clustered Index by common Script. <<

Sure. You'd need to generate and run a separate DISABLE command for each index.

>> How can I Rebuild 5 Non clustered Index for Table ? <<

You'd likewise have to generate and run a separate REBUILD command for each index.

Thanks for your Reply.

I understood that, I don't need to disable clustered index. Can I ask you Why?

Thanks

Why do you think you need to disable the clustered index?
