Tables Locked for Update/Delete
I can't believe I'm having to ask this, but can anyone give a reason why a table would prevent you from updating or deleting? I have no problems inserting or selecting from these tables, and not all of the tables in the database are like this. Only a few, and this just started happening two days ago...previously, they were functioning properly. Now, an update or delete statement will lock up both my applications and SQLPLUS.
Thanks,
Jesse
