I have a range partitioned table contains 4 partitions and the table has 2 normal indexes.

When I was dropping an one partition from the table through the following way,

alter table <table_name> drop partition <partition_name>;

the indexes are present in the table become UNUSABLE.

So to avoid this, Shall I use the below query to drop a partition?

alter table <table_name> drop partition <partition_name> update global indexes;

Note: there are 2 CLOB columns in that table.

Yes, you can.
Why don't you just try it instead of posting the question?

Thanks for your immediate response.
It is a production db. So just like that I cannot try. Thatsy..

for any type of indexes, can I use this format?

So you will trust and execute in production a statement you will get from a forum.
Gee! Good luck for the future.

You can do it for all global indexes but you should read the documentation about the consequences and restrictions of this statement.
When you rebuild online all statements that the index and is running may fail with an ORA-01555 or ORA-01410 error.
