ORA-01502: index or partition of such index is in unusable state
557505Aug 1 2007 — edited Aug 1 2007Hi All,
I am getting this error while executing a select statement. What is the cause for this.
How to resolve it.
Also,
What things can cause the index to become unusable and how can I ensure that the index will not become unusable again (once I rebuild it).
Any help will be appreciated.
Thanks.
