I have a situation on where I am receiving information or data from a vendor or third party. The problem is that they have a front end free form field that is designated for a phone number. I need to be able to parse through this field of data and only extract numeric data. So for an example, if I am given a free form value of:
1 (404) 653-9832
End Result to Extract:
Is there an efficient way about going about this? I have no access or control on the vendors side to locking down the format on the front end. I am currently working on 11g Oracle database.
