I would like to know why, if I alter a table name to different name and then create a table with the same name, I am getting the error "name already been used by existing constraint".
This is the create table code
create table abc
(
num number (4),
name varchar2 (50),
constraint abc primary key (num, name)
);
This is the alter table code
alter table abc rename to cba;
This is the code to recreate the table
create table abc
(
num number (4),
name varchar2 (50),
constraint abc primary key (num, name)
);
