NEW QUESTION # 290
Examine the description of the SALES table:
The SALES table has 55,000 rows.
Examine this statement:
Which two statements are true?
Answer: A,B
NEW QUESTION # 291
Which two true about a sql statement using SET operations such as UNION?
Answer: B,C
Explanation:
In the context of SQL statements using SET operations like UNION in Oracle Database 12c:
* A. The data type of each column returned by the second query must be implicitly convertible to
* the data type of the corresponding column returned by the first query. This is correct. Oracle allows the union of columns as long as their data types are implicitly convertible, not necessarily identical.
* C. The number, but not names, of columns must be identical for all SELECT statements in the query. This is correct. For a UNION operation to be valid, all SELECT statements involved must have the same number of columns, although their names and exact data types need not match.
Options B, D, and E are incorrect:
* B is incorrect because exact data type matches are not required, only that they be implicitly convertible.
* D is also incorrect for the same reason as B; it's enough that the types are compatible, not identical.
* E is incorrect as the names
NEW QUESTION # 292
Examine the description of the ORDER_ITEMS table:
Examine this incomplete query:
SELECT DISTINCT quantity * unit_price total_paid FROM order_items ORDER BY <clause>; Which two can replace <clause> so the query completes successfully?
Answer: B,C
Explanation:
In a SELECT statement with DISTINCT, the ORDER BY clause can only order by expressions that are part of the SELECT list.
A . quantity alone is not sufficient to replace <clause> as it is not included in the SELECT list after DISTINCT.
B . This option can successfully replace <clause> because both quantity and unit_price are used in the SELECT expression, and thus their individual values are valid for the ORDER BY clause.
C . total_paid is an alias for the expression quantity * unit_price, but it cannot be used in the ORDER BY clause because Oracle does not allow aliases of expressions in DISTINCT queries to be used in ORDER BY.
D . product_id is not included in the SELECT list after DISTINCT and thus cannot be used in ORDER BY.
E . The expression quantity * unit_price is exactly what is selected, so it can replace <clause> and the query will complete successfully.
Reference:
Oracle Database SQL Language Reference, 12c Release 1 (12.1): "ORDER BY Clause"
