MYSQL merge csv data with exisiting table
I have a MYSQL table with demographic data. The addresses contained in the table were entered manually before the advent of online postcode lookup software and, hence, there are a lot of errors when using automated online mailing checking software. I plan to export the data as csv file for a 3rd party to do a bulk correction and then reimport the data. The problem is that the database will continue to be used and the demographic table also includes other data (such as dates and times, etc) than might change in the meantime, for example each row will have the following fields:
Code:
ID, Surname, firstname, dob, street, address2, town, county, postcode, tel, email, dateseen, nextdate

Obviously the address fields for some records will change in the csv file and the date fields may change in the original database table. So how do I go about importing the corrected data fields while leaving the unchanged fields that same? Would it be sensible to export only the address fields?
