Query, PL-SQL Programming

Assignment Help:
ALTER TABLE bb_basketitem
ADD CONSTRAINT bitems_qty_ck CHECK (quantity < 20);

BEGIN
INSERT INTO bb_basketitem
VALUES (88,8,10.8,21,16,2,3);
END;
Brewbean’s wants to add a check constraint on the QUANTITY column of the
BB_BASKETITEM table. If a shopper enters a quantity value greater than 20 for an item,
Brewbean’s wants to display the message “Check Quantity” onscreen. Using a text editor, open
the assignment04-06.txt file in the Chapter04 folder. The first statement, ALTER TABLE,
must be executed to add the check constraint. The next item is a PL/SQL block containing an
INSERT action that tests this check constraint. Add code to this block to trap the check
constraint violation and display the message.
