Modify the following SQL command to make the changes below. CREATE TABLE store_reps ( rep_ID NUMBER(5), last VARCHAR2(15), first VARCHAR2(10), comm CHAR(1) ); • make the rep_ID primary key. • assign a default value Y to the comm column. • make the comm column to accept only Y or N. Create a new table named REP_CONTRACTS containing the columns listed below. Make a composite primary key including the rep_ID and quarter. In addition, create a foreign key constraint to link two tables. • name: A character field that can contain up to 15 characters. • quarter: A character field that can contain up to 3 characters. • rep_ID: A number field that can contains integers up to 5 digits.
