Hi:
I started using the auto-incrementor available in 12c. I personally think it's the greatest feature since the slice of bread. No longer to you have to create a sequence and use the trigger to get the next value. I can use trigger for much better things.
But here's the problem I have run into. I have created a table wrongly identifying a column as an auto-incrementor.
I tried altering the table and dropping the default but I get errors.
Thanks.
