Hello all,

I have a colum in Access looks like this

Name                                                  Id
Angervil, Moliere (PS, APS)                           1
Arocha, Fernando (PS, Contractor, EDF)                2
...

I need to trim the Name colum that only have the last 3 letters.  In this case, are APS and EDF.  Sometimes there are two ","s and sometimes just one.

How can I do this?

Thanks for your help.

update tbl
set name = left(name,len(name - 6) & ")"
where right(name,6) in (", APD)",", EDF)")

Ok, I guess my question is: How do I find out the position of a charater in a given string?  ie. abcdefgh, the position of d is 4.  Is there a function that I can do that?

Thanks

To find the position of a character in a string in Access, use the InStr function, e.g.:

Select InStr("abcdefgh", "d") As DPos

Returns 4

Now, going to your first case, the Right function should work to your advantage:

Select Mid([Name], InStr([Name], ")") - 4,3) As LastEntry
FROM MyTable

Oops - that should be:

Select Mid([Name], InStr([Name], ")") - 3,3) As LastEntry
FROM MyTable

Hi If you just want to get the last 3 letters within the brackets then you could try either of these.

Mid((Right(RTrim([name]), 4)), 1, 3)

Mid(RTrim([name]), Len(RTrim([name])) - 3, 3)

if there are following spaces the RTrim will remove them
good luck
