OK. The problem is I don't want the next "highest" number.
There are gaps in the UID sequence. I need to find the next UNUSED
number in the sequence which is rarely the "highest" number.

If its an autoincrement, the next highest number will be assigned by the
db.
There is no need to query the db to find it. Simply insert the record
and
leave the id field out of the insert statement.
