Full Discussion: MYSQL merge csv data with exisiting table

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?

px_get_info

PX_GET_INFO(3)															    PX_GET_INFO(3)

px_get_info - Return lots of information about a paradox file

SYNOPSIS

       array px_get_info (resource  $pxdoc)

DESCRIPTION

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database as returned by px_new(3).

RETURN VALUES

	Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future.

	      o fileversion
		-Version of file multiplied by 10, e.g. 70.

	      o tablename
		-Name  of  table  as  stored in the file. If the database was created by pxlib, then this will be the name of the file without the
		extension.

	      o numrecords
		-Number of records in this table.

	      o numfields
		-Number of fields in this table.

	      o headersize
		-Number of bytes used for the header. This is usually 0x800.

	      o recordsize
		-Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2).

	      o maxtablesize
		- This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer
		part of (maxtablesize * 0x400 - 8) / recordsize.

	      o numdatablocks
		- The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and
		the data block size (maxtablesize). Data blocks may not necessarily be completely filled.

	      o numindexfields
		- Number of fields used for the primary index. The fields do always start with field number 1.

	      o codepage
		- The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targeten-
		coding(3)   this  will	be  the  encoding  for	character  fields  when  records  are  being  accessed	with  px_get_record(3)	or
		px_retrieve_record(3).
