[mythtv-users] Should I be locking tables if I change mythconverg data in a script?

[nospam312]

I currently run a script regularly to tidy up data in the mythconverg
database.  Currently I have no locking functionality in the script so
I guess if myth tries to access the data at the same time as the
script is updating some data things may go wrong.

Should my script have some locking/unlocking in it and if it should is
there any examples of what I should be doing?

TIA
