    Can you provide a sample of the data?

      function randomId() do
    let chars := "1234567890ABCDEFGHJKLMNPQRSTUVWXYZ";
    let len := length(chars);
    join(for i from 0 to 8 do
        substr(chars, floor(random() * len), 1)
    end, "")
end;
let done := false;
while not done do
    let i := randomId();
    if count(select 'Orders' where 'Random letters and numbers' = i) = 0 then
        'Order Number' := "H" + randomId() + "B";
        done := true
    end
end

          if count(select 'Orders' where 'Random letters and numbers' = i) = 0 then

      thanks,The condition statement is like this, but if there are duplicates, how to generate a non-duplicate number again, how to write this.

      I'm not sure what you want to do. You ask to "edit out unique non-repeating random numbers". Then you give a string that has numbers and letters. Can you describe in more detail what you want to have happen?

      The random numbers I generate with this piece of code have a probability of repeating, so how can I solve this problem?
