Oracle Database SQL Sample Questions (Q176-Q181):

NEW QUESTION # 176
View the Exhibit and examine the details of the ORDER_ITEMS table.

Evaluate the following SQL statements:
Statement 1:
SELECT MAX(unit_price*quantity) "Maximum Order"
FROM order_items;
Statement 2:
SELECT MAX(unit_price*quantity) "Maximum Order"
FROM order_items
GROUP BY order_id;
Which statements are true regarding the output of these SQL statements? (Choose all that apply.)

A. Both the statements would give the same output.
B. Statement 1 would return only one row of output.
C. Statement 1 would not return give the same output.
D. Statement 2 would return multiple rows of output.
E. Both statements would ignore NULL values for the UNIT_PRICE and QUANTITY columns.

Answer: B,D,E

NEW QUESTION # 177
Which two are true about scalar subquery expressions?

A. They can return at most one row.
B. .You must enclose them in parentheses.
C. You cannot correlate them with a table in the parent statement
D. They can return two columns.
E. You can use them as a default value for a column.

Answer: A,B

Explanation:
Scalar subquery expressions in Oracle SQL have specific rules:
* Option C: You must enclose them in parentheses.
* Scalar subqueries must be enclosed in parentheses. This is a requirement for syntax clarity and to distinguish the subquery from the rest of the SQL statement.
* Option D: They can return at most one row.
* Scalar subqueries are designed to return exactly one row containing one column. If a scalar subquery returns more than one row, Oracle will throw an error, ensuring that the subquery either returns a single value or no value (NULL).
Options A, B, and E are incorrect based on Oracle SQL functionalities:
* Option A is incorrect because scalar subqueries can indeed be correlated with the parent query.
* Option B is true but not in the context of default constraints for table columns in the CREATE TABLE statement.
* Option E is incorrect because scalar subqueries can only return a single column by definition.
