Hi!
Sorry for my English..
I want to dinamcly change type of column. If possible, of course.Trivial idia - create new temporary column, try to write value from old columt to temporarity (if type conersion ok - this made using select/update command and type conversion checks on client's side), then delete old column, and rename temporary column.. But this decision looked quite ill...
Do you have better idea?
