VI_JobLog.m4t is inaccessible, as far as I know, using ODBC. On a Premium system SY_User is in SQL, so I didn't even try to set up a Providex DSN, thinking it would be ineffective without a way to authenticate a user. The SQL databases do not refer to this table, even in a View.
I also know nothing about ProvideX utilities. Is this something a non-developer could set up?
(And thanks for the replies).
