Before Oracle 12c we couldn't have sequence as default value for a column, but now we can use sequence as default value as sequence.nextval.
When new row is added, sequence automatically increments and writes the column.
Below is the example:
Create sequence seq_t start with 1 increment 1 nocycle; Create table t_my_tab (id number default seq_t.nextval primary key)
