NEW QUESTION # 282
Which three statements are true about single row functions?

A. The argument can be a column name, variable, literal or an expression.
B. They can accept only one argument.
C. They can be used only in the where clause of a select statement.
D. They return a single result row per table.
E. They can be nested to any level.
F. The date type returned can be different from the data type of the argument.

Answer: A,E,F

Explanation:
Single-row functions in SQL operate on each row independently and can modify the returned value:
* Option A: Incorrect. Single row functions can be used in multiple parts of a SELECT statement, including SELECT, WHERE, and ORDER BY clauses.
* Option B: Incorrect. Single row functions can accept more than one argument, such as the CONCAT function, which can accept multiple string arguments.
* Option C: Incorrect. They return one result for each row processed, not per table.
* Option D: Correct. Single row functions can take various types of arguments including column names, literals, variables, and other expressions.
* Option E: Correct. Functions can be nested within other functions, allowing complex expressions and calculations.
* Option F: Correct. The data type of the result can differ from the arguments' data types, such as the SUBSTR function returning a VARCHAR2 even when used on a number after converting it to a string.

NEW QUESTION # 283
Which three statements are true?

A. A product can have a different unit price at different times.
B. A customer can exist in many countries.
C. The SALES table has five foreign keys.
D. The statement will fail if a row already exists in the SALES table for product 23.
E. The statement will fail because subquery may not be I contained in a values clause.
F. The statement will execute successfully and a new row will be inserted into the SALES table.

Answer: A,B,E

Explanation:
* A. A customer can exist in many countries. This is true as customers can have multiple addresses or operations in different countries, and a database design can reflect this by allowing multiple country entries for a single customer1.
* C. The statement will fail because subquery may not be I contained in a values clause. In Oracle Database 12c, a subquery cannot be used within the VALUES clause of an INSERT statement. The correct approach would be to use the subquery in conjunction with the INSERT INTO ... SELECT syntax if multiple rows are derived from a subquery2.
* F. A product can have a different unit price at different times. It is common for products to have different unit prices at different times due to various factors such as promotions, discounts, or changes in cost price. This can be represented in a database by having a price history table or a similar mechanism to track the changes in price over time1.
Note: The other options are incorrect because:
* B. The statement about the SALES table failing if a row already exists for product 23 is not necessarily true. Oracle allows for multiple rows with the same product ID if the table is designed to handle such cases, like having a composite primary key or no constraints preventing duplicates.
* D. Without specific information about the SALES table's design, we cannot verify the number of foreign keys it has.
* E. The statement about the successful execution and insertion of a new row into the SALES table is too vague without the context of the actual SQL statement being referred to.

NEW QUESTION # 284
Which three statements are true about views in an Oracle Database? (Choose three.)

A. A SELECT statement cannot contain a WHERE clause when querying a view containing a WHEREclause in its defining query.
B. Views have no segment.
C. Views can join tables only if they belong to the same schema.
D. Views have no object number.
E. Rows inserted into a table using a view are retained in the table if the view is dropped.
F. A view can be created that refers to a non-existent table in its defining query.

Answer: B,E,F
