hi i have 2 database MS Access and mySQL 5.5

there are some updated data from the Access database that i want to transfer over to the mySQL but i don't want to just copy the whole table..

my reason:

eg: only invoice number : 1111014 - 1111050 from the access are the newer than the data in mySQL for the rest of the data mySQL has the updated values..

Datatype:
InvoiceNumber in mySQL - varChar(50)
InvoiceNumber in Access- text
