试试这个：

UPDATE table
SET  FirstName  = SUBSTRING(FullName, CHARINDEX(',', FullName)+1, CHARINDEX(' ',FullName)-CHARINDEX(',', FullName)-1)
    ,MiddleName = SUBSTRING(FullName, 0, CHARINDEX(',', FullName))
    ,LastName   = SUBSTRING(FullName, CHARINDEX(' ', FullName)+1, LEN(FullName)-CHARINDEX(' ', FullName)+1)
