How do i lock table in oracle, i tried LOCK TABLE Table_name IN EXCLUSIVE MODE and 3 other modes but still i was able to insert data in to the table. I want to lock the table so that the table would reject any data that is being inserted or updated in to this table.


RE: Lock

Locking the table in exclusive mode should have prevented other sessions from updating the table for the duration of the transaction that's holding the lock, but doesn't prevent updates from the session that created the lock. If that's your intent - to prevent yourself from accidentally updating the table while running a query, you should try using "SET TRANSACTION" to create a read-only transaction. An example of doing this can be found in the Oracle documentation, for example


RE: Lock

Thanks for the reply.

I am trying to lock the whole table,not allow any transcation to the table what so ever. Will SET TRANSACTION work?


RE: Lock

do you try to make the table read only? The syntax for this is:


Its a new feature in 11g and will prevent the owner from updating/inserting too.
