Integer problem of setting 1 bit in oracle
The first is the id number (1). Try it and see if the generated field declaration is boolean.

Secondly, you can try to assign a value to this field, such as "3", to see if it can be successful. If it succeeds, it means there is no impact. If it is wrong, it means that there is something wrong with this field when it is created.

Finally, you try with the id number (2,0), is that right? This situation generally does not happen. Good luck.
