is it possible to convert "-" to "_"

[beckham]

Hi Guys my database as 50,000 records and 1 field as the following formatting (7numbers-2numbers-5numbers) "1234567-01-12345" and i would like to change all the "-" to "_" without effecting the numbers, is this possible? if so then i would like to make all future entries use the underscores automatically in place of hyphens?

Thanks for any help..

Make a backup first:

do a replace on your field:  Substitute ( your::field ; "-" ; "_" )   will replace existing data. 

in the auto entry field you can use:  Substitute ( self ; "-" ; "_" )
