Default Pulling specific data from table field

I am having a problem figuring the right way to pull specific data from
within the text of the table's field and separating it into a unique field
alone.

Anyway, my problem is that I need to copy a user's first name out of a field
that contains system user information, and then pull the last name out
separately as well, both uniquely. I don't mind having separate queries to do
this (although one would be preferred of course).

Table: tbl1
Field: userinfo

Example of field data: ABD 000000 111, Doe John, R, W, T22222222, T333333

The ABC and 111 are constants within the field, and the 000000 is a serial
number with a standard length of 6.

I currently have a sql query that pulls the serial number:
UPDATE tbl1
SET tbl1.[Serrial Number] = Right(Left([tbl1].[userinfo],10),6);

Obviously this won't work with for a last name or first name because the
number of letters within a name can change... so I'm stumped as how to
correctly format a query to copy the last name and first name into a separate
field.

Any thoughts?

Try these --
LName: Mid([tbl1].[userinfo], 17, Instr(20,[tbl1].[userinfo], " ")-16)

FName: Mid([tbl1].[userinfo],InStr(20,[tbl1].[userinfo],"
")+1,InStr(23,[tbl1].[userinfo],", ")-InStr(20,[tbl1].[userinfo]," ")-1)

Then build on the first name one for initals.

Karl's code will let you handle the simple cases, but there are names that
don't fit the pattern. What about a name like "Billy Joe McAlister" - first
name Billy Joe (just ask him)? And how about "Hans ten Broek" - first name
Hans, last name ten Broek?

Names are messy, and may well require a USB (Using Someone's Brain) interface.

Default Pulling specific data from table field

Karl,

Thanks for you help on this one, it really was just frustrating me! The
Last Name search completely worked, but I am having issues pulling the First
Name data.

When running the First Name query, an error is returned saying Access
was unable to update a number of fields due to a type conversion failure. It
states this is due to key violations, lock violations, and validation rule
violations.

I'm wondering if this is because of what John menioned in this string,
which is something I have found to be true of my table. There are a few
instances of a third name being within the userinfo field. I should have
perused my file to recognize that issue, but in my frustration it seems I
overlooked the third name.

Example: ABC 000000 111, Doe John Paul, R, W, T222222

I'm not sure there is an answer as how to work around this problem, but
thought I'd at least give some feedback as to how the help you'd given me
worked out. Thanks again for the suggestion and I'm going to keep working on
this and see if there is a solution to my problem.

First you have to figure out which of the reasons give you the error. Review
what worked and then look at what did not.
