Never used LOCK TABLE
This is what Gemini (google) says :
Manual Unlocking: Unlike some databases, there is no UNLOCK TABLE SQL command. On IBM i, you release the lock by:
1. Committing or Rolling back your transaction.
2. Closing the connection/ending the job.
3. Using the CL command DLCOBJ (Deallocate Object) if the lock was scoped to the job.

Hello,
I have found that you can place an exclusive lock tables in V4R5 like this:
LOCK TABLE [tablename] IN EXCLUSIVE MODE
However, I was unable to find out how to remove this lock from within SQL. There is no UNLOCK TABLE SQL command.
Any hints?
:wq! PoC
