How do I extract only the numbers in a string?

I have several records in an Access table that contain a mixture of letters and numbers. I want to create a new record with only the number portion remaining. For example the string "6ABC12345" would give me 612345.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you will need VBA codes to do that

place this code in a regular module

function getNumbersOnly(varStr as string)
if varStr & ""="" then getNumbersOnly="" : exit function

dim j as integer, num as string
for j=1 to len(varStr)
   if  isnumeric(mid(varStr,j,1)) then
      num=num & mid(varStr,j,1)
  end if
if num & ""<>"" then
end if

end function

Open in new window

to use the function  in a query

select [fieldname], getNumbersOnly([fieldname]) from tableX
