Answer:
Hi!
The correct answer is B.
Explanation:
This sentence SELECT * FROM customers JOIN orders ON (customer#) selects all the columns of both customers and orders and joins by the name of the column customer.
A and B options have syntactic problems:
- A and C: Same alias name for multiple tables.
- A and C: Selected columns are ambiguous.
- C: refers to an alias not declared on the FROM sentence.
a) SELECT c.customer#, order#, orderdate, shipdate(omits aliases) FROM customers c NATURAL JOIN orders c(same aliases definiton);
c) SELECT c.customer#, order#, orderdate, shipdate(omits aliases) FROM customers c, orders c(same aliases definiton) WHERE c.customer# = o.customer#(o not declared);
The "A" is converted to its ASCII binary code and stored in the memory unit. Then it is converted back to "A" for display.
Hope this helps!
