c# - How to create sequence for foreign key in oracle? -


i have 1 table employees columns id number(2) primary key, name varchar2(20) not null, pid number(2) not null.

pid has foreign key id in same table.

i want create combo box contains values column name. also, when select value column name, after clicked on button, have create value pid in table employees.

i tried insert auto_increment sequence pid, wasn't work, because it's not primary key.

so, don't have idea how solve step. because it's complicated when have columns in 1 table.

is id value equal pid ?

if yes, guess have database design issue.

if not, can try use sequence of id column.
