| Hi AllI have a table of approx 500,000 members which I need to dedupe only by email address. and i dont mind which records get removed. as long as there is a unique email address.e.g. tom, harrow, tom@tom.com, 30/09/1978, blue, £456thomas, harrow, tom@tom.com, <NULL>, blue, £456tom, harrow, tom@tom.com, 30/09/1978, <NULL>, <NULL>I dont mind which record remains... as long as there are no duplicate email addresses.I have tried a number of ways but none seem to work properly and the only effective method opnly keeps one field(email) i.e. creates a table with only distinct email addresses. Any help hugely appreciated.ThanksTom |
