Answer 1

you can define the primary key when you create table
or add the primary key after the table creation by 'ALTER TABLE ... ADD constraint pk_nme primary key (col1, col2)';
you could use below sql to check the detail of primary key:
1) check out the table definition directly:
select dbms_metadata.get_ddl('TABLE','EMP') FROM DUAL;
2) check out the columns of primary key:
select * from user_constraints where constraint_type='P' AND table_NAME='EMP';
select * from user_cons_columns where CONSTRAINT_NAME='PK_EMP';And BTW, it is madam, not sir. :)
