Tim,
Another idea would be to use a fourth field along the three already in the PK, to store year of birth... I would hope there would be no twins with the same name, though first cousins with the same name living in the same building and born in the same year is always a possibility!!!

It is forbidden to use them for linking outside the health service, even to store them on non-NHS systems Anyway, nobody knows their number Anyway, they are not duplicate-free (but what do you expect from Government IT systems?)... We also have National Insurance Numbers but they are not widely used outside the taxation/ employment spheres, for reasons similar to above. All the best Tim F |

We've missed one more possibility: misspellings. Take a look at my surname
and try to guess how many different spellings of it I've seen over the years, then multiply by ten to be closer! How many records would I get? g Unfortunately, that is the inevitable problem with every Customer, Supplier, Member, etc. table on the planet. I don't think anyone has found a solution to it either...and they probably won't. -- Lynn Trapp MS Access MVP www.ltcomputerdesigns.com Access Security: www.ltcomputerdesigns.com/Security.htm |

Christian & Christine; Francesca and Francis; Jan and Jon; etc.... Please, just believe it -- names make rotten unique identifiers! All the best Tim F |
