[Maurizio, Sponda]

Hi! i have a question:   FIELD IN MS SQL SERVER ------------------------ FiledName: uiAutID DataType: unique identifier DefaultValue: newid() Is RowGuid: Yes   how i can describe the some column in MySQL? if isn't possible, how can i solve my problem?   P.S.: is necessary for us, use "unique identifier" data type because the datas must be exchanged with others companies and we need garantee unique identification of all the informations.   Maurizio, Sponda Italy
