NEW QUESTION # 417
Examine this SQL statement:
SELECT cust_id, cus_last_name "Last Name"
FROM customers
WHERE country_id = 10
UNION
SELECT cust_id CUST_NO, cust_last_name
FROM customers
WHERE country_id = 30
Identify three ORDER BY clauses, any one of which can complete the query successfully.

A. ORDER BY 2,cust_id
B. ORDER BY CUST_NO
C. ORDERBY 2, 1
D. ORDER BY "CUST_NO"
E. ORDER BY "Last Name"

Answer: C,E

Explanation:
In SQL, the ORDER BY clause can refer to columns by their alias defined in the SELECT clause or by their positional number in the SELECT list. It's important to understand that after a UNION, the column names in the ORDER BY clause refer to the first SELECT statement's column names and aliases:
* Option A: ORDER BY 2, 1This is correct because it refers to the second and first columns in the first SELECT clause, which correspond to the aliases "Last Name" and cust_id, respectively.
* Option E: ORDER BY "Last Name"This is correct because "Last Name" is a valid alias defined in the first SELECT clause.
The other options fail for the following reasons:
* Option B: "CUST_NO" is not recognized in the ORDER BY clause because it's not an alias used in the first SELECT statement.
* Option C: Incorrect because 2, cust_id mixes positional reference with a column name that doesn't apply to both SELECT statements consistently.
* Option D: ORDER BY CUST_NO fails because CUST_NO is not an alias in the first SELECT clause.

NEW QUESTION # 418
Which three statements are true regarding single-row functions? (Choose three.)

A. They can be nested up to only two levels.
B. They can be used in SELECT, WHERE, and ORDER BY clauses.
C. They can accept column names, expressions, variable names, or a user-supplied constants as arguments.
D. The data type returned, can be different from the data type of the argument that is referenced.
E. They can return multiple values of more than one data type.
F. They can accept only one argument.

Answer: B,C,D
