新问题 129
Which is true about the & and && prefixes with substitution variables?

& can prefix a substitution variable name only in queries. DML

An & prefix to an undefined substitution variable, which is referenced twice in the same query, will prompt for a value twice .

The && prefix will not prompt for a value even if the substitution variable is not previously defined in the session.

An && prefix to an undefined substitution variable, which is referenced multiple times in multiple queries, will prompt for a value once per query.

Both & and && can prefix a substitution variable name in queries and DML statements.

E). True. Both & and && can prefix substitution variables in queries as well as in DML statements. & is used for defining a substitution variable that prompts the user every time the variable is encountered. && is used for a persistent substitution variable that, once defined in the session, will not prompt the user again for a value if used subsequently.

A transaction can consist of one or more DML statements.

DML disables foreign key constraints when deleting primary key values in the parent table, only when the ON DELETE CASCADE option is set for the foreign key constraint.

Examine the description of the EMPLOYEES table:

NLS_DATE FORMAT is DD-MON-RR.
Which two queries will execute successfully?

SELECT dept_ id, AVG (MAX(salary)) FROM employees GROUP By dept_id HAVING hire_date> ‘ O1-JAN-19’;

SELECT dept_ id, AVG(MAX(salary)) FROM employees GROUP BY dept_id, salary;

SELECT dept id, MAX (SUM(salary)) FROM employees GROUP BY dept_id;

SELECT dept_ iD, sum(salary) FROM employees WHERE hire_date > ’01-JAN-9′ GROUP BY dept_id;

SELECT AVG(MAX(salary)) FROM employees GROUP BY salary;

新问题 140
View the exhibit and examine the description of the DEPARTMENTSand EMPLOYEEStables.

You wrote this SQL statement to retrieve EMPLOYEE_ID, FIRST_NAME, and DEPARTMENT NAME, for all employees:
SELECT employee_id, first_name, department_name
FROM employees
NATURAL JOIN departments;
The desired output is not obtained after executing the above SQL statement. What could be the reason for this?

The table prefix is missing for the column names in the SELECTclause.

The NATURAL JOINclause is missing the USINGclause.

The DEPARTMENTStable is not used before the EMPLOYEEStable in the FROMclause.

The EMPLOYEESand DEPARTMENTStables have more than one column with the same column name and data type.

说明/参考：
解释：
Natural join needs only one column to be the same in each table. The EMPLOYEESand DEPARTMENTS tables have two columns that are the same (Department_ID and Manager_ID)
