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?

pilot-addresses(1)						    PILOT-LINK							pilot-addresses(1)

NAME
pilot-addresses - Read and write address book databases to and from a Palm handheld. SECTION
pilot-link: Userland conduits LOCATION
./src SYNOPSIS
pilot-addresses [-p|--port <port>] [--version] [-?|--help] [--usage] [-q|--quiet] [--delete-all] [-t|--delimiter INT] [-d|--delete-cate- gory category ] [-c|--category category] [-a|--augment] [-r|--read file] [-w|--write file ] [-C|--human-readable] DESCRIPTION
pilot-addresses allows the user to read all entries from a Palm handheld such as those made by Palm, Handspring, Handera, TRGPro, Sony or other Palm handheld in the Palm Address Book application, write new entries into the database, and delete a category or delete all entries in the database. COMMANDS
Provide exactly one of --read or --write. -r, --read=<file> Reads records from <file> and install them to the Palm Address Book application. (Use the -w <file> option to get a sample "template file" for input records to see how the fields are laid out). -w, --write=file Reads all address book records from the Palm Address Book application and writes them into file OPTIONS
pilot-addresses options -a, --augment Augments fields in address book records with additional information. The augmented information is placed before and separated from the field with a semi-colon, (;). Augmented information can include any of the following below. category # Placed in front of each record or.. Placed in front of each phone number field: ["Work"|"Home"|"Fax"|"Other"|"E-mail"|"Main"|"Pager"|"Mobile"] Empty fields are not augmented. -c, --category=category Install records to category category by default. Normally pilot-addresses uses the Unfiled category by default. This option is overridden by the category specified in the record with the -a option. -d, --delete-category Delete all records in the specified category category before installing new records. Note that the long name of this option has changed since 0.11.8 -D, --delete-all Delete all address book records in all categories. Obviously, be very careful with this one. Note that the long name of this option has changed since 0.11.8 -t, --delimiter INT Include category in each record, use the delimiter specified to separate all fields of a record. Delimiters are specified as follows: 3=tab, 2=;, 1=,. This overrides the default delimiter of comma between fields and semi-colon between a field's augmented information. (Please note that this may generate confusing results when used with the -a option.) Note that the long name of this option has changed since 0.11.8 -T, --titles Obsolete. This option has been removed since 0.11.8 -C|--human-readable Write generic human-readable output instead of CSV. Conduit Options -p, --port <port> Use device file <port> to communicate with the Palm handheld. If this is not specified, pilot-addresses will look for the $PILOTPORT environment variable. If neither are found or supplied, pilot-addresses will print the usage information. -q, --quiet Suppress 'Hit HotSync button' message -v, --version Display version of pilot-addresses and exit without connecting. Help Options -h, --help Display the help synopsis for pilot-addresses and exit without connecting. --usage Display a brief usage message and exit without connecting. USAGE
The program will connect to the Palm handheld, and perform the requested read or write operation specified by the user. EXAMPLES
To write all address records in a Palm to the file addrbook.csv: pilot-addresses -w addrbook.csv or pilot-addresses -p /dev/pilot -w addrbook.csv To read the address book records in the file addrbook.csv and install them onto the Palm: pilot-addresses -r addrbook.csv To read the address book records in the file addrbook.csv and place them into the Palm address book database category Special after first deleting all current records in the Special category on the palm: pilot-addresses -c Special -d Special -r addrbook.csv AUTHOR
