I remember reading an article somewhere on the Web that reviewed the
circumstances under which it was not possible to update data in a query.
I can not find it.
I would be grateful if a kind soul to direct me to information that would be
pertinent.

Thank you,
Pepper
 
In the ACCESS help, type update. Under update queries it has a piece about
what is updateable and what is not.
 
In Access Help type the following in the Answer Wizard tab
When can I update data from a query
Select that from the list for an explanation of some of the causes and
alternative solutions.

Access MVP Allen Browne has summarized the reasons:

Query results will be read-only if any of the following apply:
.. It has a GROUP BY clause (totals query).
.. It has a TRANSFORM clause (crosstab query).
.. It contains a DISTINCT predicate.
.. It uses First(), Sum(), Max(), Count(), etc. in the SELECT clause (performs
aggregation).
.. It involves a UNION.
.. It has a subquery in the SELECT clause.
.. It uses JOINs of different directions on multiple tables in the FROM clause.
.. The query's Recordset Type property is set to Snapshot.
.. The query is based on another query that is read-only (stacked query.)
.. Your permissions are read-only (Access security.)
.. The database is opened read-only, or the file attributes are read-only, or
the database is on read-only media (e.g. CD-ROM, network drive without write
privileges.)
