  • 0

I have address data stored in an sql server 2000 database, and I need to pull out all the addresses for a given customer code. The problem is, there are a lot of misspelled addresses, some with missing parts, etc. So I need to clean this up somehow. I need to weed oout the bad spellings, missing parts, etc and come up with the “average” record. For example, if New York is spelled properly in 4 out of 5 records, that should be the value returned.

I can’t modify the data, validate it on input, or anything like that. I can only modify a copy of the data, or manipulate it through a query.

I got a partial answer here Addresses stored in SQL server have many small variations(errors), but I need to allow for multiple valid addresses per code.

    The best solution is to use a CASS certified address standardization program or service that will format and validate the address. Beyond the USPS which has tools for this, there are many third-party programs or services which provide this functionality. Address parsing is far more complicated than you might imagine and thus trying whip up a few queries to do it will be fraught with peril.

    Google’s Geocoding is another place to look.. Apparently Google requires you display the results to use their Geocoding service. That leaves using dedicated address parsers like the USPS or a third-party program.
