From a table with data in the following format:

Name Data
CB1 xxx
CB2 yyy
CB3 zzz
AT1 mm
AT7 ww

I want to create a new table in the following format:

Name Data
CB xxx, yyy, zzz
AT mm, ww

Why?

You're going from a properly normalized table to a new table with non-atomic,
redundant, improperly structured fields.

If you want a *recordset* in the following format, for the purpose of
generating a report, use a Query with some VBA code:

If you really, really want a flawed, hard to edit, hard to search table <g>,
base an Append or MakeTable query on the query using the function.

John,

Thanks for replying.

In a table of app. 5000 records, I need to search for names whose prefixes
occur multiple times, (e.g., CB1, CB2, CB3), and then pull data from these
common records. I thought that it would be easier to merge the data from the
common records into a single record, and pull data from the merged record.

Well... given the way SQL queries work it would be considerably harder, not
easier.

You can do a totals query grouping by the prefix and counting records; it's
not quite clear how the "prefix" is stored or what you want to "pull".

Perhaps you can use the Duplicates query wizard to get what you want? Or
you can construct a query that looks like the following

SELECT *
FROM YourTable
WHERE [Name Field] in
(SELECT [Name Field]
FROM YourTable
GROUP BY [Name Field]
HAVING COUNT(*) > 1)
ORDER BY [Name Field]

That would return all records where the value of [Name field] appeared more
than one time in the table.

Once I merge the common names into a single record, I would count all of the
occurences of xxx's, yyy's, zzz's etc. (my idea was to count the number of
times the character set occurs in the merged string.) Is there a 'simple'
way to do the counts without first doing a merge?

Yes; a Totals query, grouping by the prefix and Counting the primary key. I
still don't know the structure of your table so I can't write the query, but
the query design window should let you do this; the Greek Sigma icon (looks
like a sideways M) makes a query into a Totals query.
