Evaluate the following SELECT statement and view the exhibit to examine its output:
SELECT constraint_name, constraint_type, search_condition, r_constraint_name,
WHERE table_name = ‘ORDERS’;
CONSTRAINT_NAME CON SEARCH_CONDITI
R_CONSTRAINT_NAME DELETE_RULE STATUS
ORDER_DATE_NN C “ORDER_DATE” IS
C “CUSTOMER_ID” IS
ORDER_MODE_LOV C order _mode in
ORDER TOTAL MIN C order total >= 0 ENABLED
ORDER PK P ENABLED
ORDERS CUSTOMER ID R CUSTOMERS ID SET NULL ENABLED
ORDERS SALES REP R EMP EMP ID SET NULL ENABLED
Which two statements are true about the output? (Choose two.)
The R_CONSTRAINT_NAME column gives the alternative name for the constraint.
In the second column, ‘c’ indicates a check constraint.
The STATUS column indicates whether the table is currently in use.
The column DELETE_RULE decides the state of the related rows in the child table when the corresponding
row is deleted from the parent table.
