Examine this statement:
SELECT1 AS id,' John' AS first_name, NULL AS commission FROM dual
INTERSECT
SELECT 1,'John' null FROM dual ORDER BY 3;
What is returned upon execution?[
Regarding the provided SQL INTERSECT query:
D . 1 ROW: The INTERSECT operation will compare the two SELECT statements and return rows that are identical between them. Both queries are designed to return the same values ('1' for the ID, 'John' for the name, and NULL for the commission), hence one row that is identical between the two datasets will be returned.
Incorrect options:
A: Only one identical row exists between the two datasets.
B: There is an identical row; thus, it is not zero.
C: There is no error in the syntax or execution of the query.
Which two statements will return the names of the three employees with the lowest salaries?
To retrieve the names of the three employees with the lowest salaries, the correct SQL syntax and logic are crucial:
Option B:
SELECT last_name, salary FROM employees ORDER BY salary FETCH FIRST 3 ROWS ONLY;
This query correctly sorts employees by their salary in ascending order and fetches the first three rows only. The FETCH FIRST n ROWS ONLY syntax is a standard way to limit the result set in SQL.
Options A, C, D, and E do not correctly implement the logic for fetching the lowest three salaries due to misuse of ROWNUM or incorrect placement of ORDER BY and FETCH clauses.
Which two are true about the MERGE statement?
The correct answers regarding the MERGE statement are:
B . The WHEN NOT MATCHED clause can be used to specify the inserts to be performed. This is true. When a row from the source does not match any row in the target, the WHEN NOT MATCHED clause is where you specify the insert operation.
E . The WHEN MATCHED clause can be used to specify the updates to be performed. This is true as well. The WHEN MATCHED clause is where you specify the update (or delete) operation to be performed when the source and target rows match.
Options A, C, and D are incorrect:
A is incorrect because WHEN NOT MATCHED does not handle deletions, it is for inserts.
C is incorrect as inserts are not specified in the WHEN MATCHED clause but in the WHEN NOT MATCHED clause.
D is incorrect because updates are specified in the WHEN MATCHED clause, not the WHEN NOT MATCHED clause.
You issued this command: DROP TABLE hr. employees;
Which three statements are true?
Regarding the DROP TABLE command:
A . ALL constraints defined on HR.EMPLOYEES are dropped: Dropping a table will automatically drop all constraints associated with that table.
B . The HR.EMPLOYEES table may be moved to the recycle bin: In Oracle, unless explicitly using PURGE, dropped tables go to the recycle bin, allowing recovery.
E . All indexes defined on HR, EMPLOYEES are dropped: When a table is dropped, all its indexes are also automatically dropped.
Incorrect options:
C: Synonyms are not automatically dropped when the table is dropped; they become invalid.
D: Sequences are independent objects and are not dropped when a table is dropped.
F: Views are not dropped; however, they will return errors upon being queried if their base table is dropped.
Which statement falls to execute successfully?
A.
SELECT *
FROM employees e
JOIN department d
WHERE e.department_id=d.department_id
AND d.department_id=90;
B.
SELECT *
FROM employees e
JOIN departments d
ON e.department_id=d.department_id
WHERE d.department_id=90;
C.
SELECT *
FROM employees e
JOIN departments d
ON e.department_id=d.department_id
AND d.department_id=90;
D.
SELECT *
FROM employees e
JOIN departments d
ON d.departments_id=90
WHERE e.department_id=d.department_id;
Given the statements, the failure to execute would be due to improper SQL syntax or logical structuring of the JOIN clause:
