질문 # 130
Examine these statements:
CREATE TABLE alter_test (c1 VARCHAR2 (10) , c2 NUMBER (10);
INSERT INTO alter-test VALUES ('123', 123);
Which is true about modifying the columns in Alter_TEST?
Which is true about modifying the columns in ALTER_TEST?

A. c1 can be changed to varchar2 (5) and c2 can be changed to number (13, 2) .
B. c2 can be changed to number (5) but ci cannot be changed to varchar2 (5) .
C. c2 can be changed to number (10) but c2 cannot be changed to varchab2 (10) .
D. c2 can be changed to varchar2 (10) but el cannot be changed to number (10).
E. c1 can be changed to number (10) and c2 can he changed to vahchar2 (10) .

정답：A

질문 # 131
Which statements is true about using functions in WHERE and HAVING?

A. using aggregate functions in the HAVING clause requires a subquery
B. using single-row functions in the HAVING clause requires a subquery
C. using aggregate functions in the WHERE clause requires a subquery
D. using single-row functions in the WHERE clause requires a subquery

정답：C

설명：
Single-row functions can be used in the WHERE and HAVING clauses without requiring a subquery.
However, aggregate functions, which operate on many rows to give one result per group, cannot be used in a WHERE clause unless a subquery is used because the WHERE clause is processed before the individual rows are aggregated into groups.
A). False. Single-row functions can be directly used in the WHERE clause.
B). False. Single-row functions can be directly used in the HAVING clause.
C). True. Aggregate functions cannot be used in the WHERE clause without a subquery because the WHERE clause filters individual rows before they are aggregated.
D). False. Aggregate functions are intended to be used in the HAVING clause, which is specifically for filtering groups of rows after they have been aggregated, and they do not require a subquery to be used there.

질문 # 132

Which two queries only return CUBE?

A. SELECT shape FROM bricks JOIN boxes ON weight > min_weight;
B. SELECT shape FROM bricks JOIN boxes ON weight >= min_weight AND weight < max_weight;
C. SELECT shape FROM bricks JOIN boxes ON weight BETWEEN min_weight AND max_weight;
D. SELECT shape FROM bricks JOIN boxes ON weight < max_weight;
E. SELECT shape FROM bricks JOIN boxes ON NOT (weight > max_weight);

정답：B,E

설명：
Based on the table structure given in the image, to return the value 'CUBE' from the 'bricks' table when joined with 'boxes', the condition must ensure that the weight of the bricks is within the allowed weight range specified in the 'boxes' table for a 'SMALL' box size.
A). True. Since MAX_WEIGHT is 0, a comparison using >= min_weight AND weight < max_weight will only return rows where the weight is less than 0, which is impossible for actual weight values, suggesting there might be a mistake in the data provided or the comparison logic.
E). True. NOT (weight > max_weight) effectively translates to 'where weight is less than or equal to max_weight'. However, since MAX_WEIGHT is 0, this condition would only be true if the weight is not greater than 0, which can only happen if the weight is 0 or less. This seems to indicate an anomaly where either the data is incorrect, or the condition is meant to handle a case where the weight is zero or possibly a negative placeholder value.
Both B and D will potentially return more than just 'CUBE' if there are bricks with weights greater than MIN_WEIGHT. C is incorrect because BETWEEN is inclusive, and there are no weights that are both greater than or equal to MIN_WEIGHT and less than or equal to MAX_WEIGHT when MAX_WEIGHT is
0.

질문 # 133
Examine this query:
SELECT employee_id, first_name, salary
FROM employees
WHERE hiredate > 61*
Which two methods should yours to prevent prompting for hire date value when this queries executed?

A. Store the query in a script and pass the substitution value to the script when executing it.
B. Execute the SET VERIFY ON command before executing the query.
C. Execute the SET VERIFY OFF command before executing the query.
D. Replace 's1' with &1'in the query:
E. Use the UNDEFINE command before executing the query.
F. Use the DEFINE command before executing the query

정답：C,F

설명：
To prevent the prompting for a substitution variable value when executing a query:
B . Execute the SET VERIFY OFF command before executing the query: This command turns off the substitution variable prompting, which means that SQL*Plus will not prompt for a value and will use whatever value is currently set for that variable.
F . Use the DEFINE command before executing the query: By using the DEFINE command to set a value for the variable before the query execution, you ensure that SQL*Plus uses this predefined value instead of prompting for it.
Reference:
Oracle SQL*Plus User's Guide and Reference, which discusses how to manage substitution variables.

질문 # 134
Examine the data in the EMPLOYEEStable.

Which statement will compute the total annual compensation for each employee?
SELECT last_name, (monthly_salary * 12) + (monthly_salary * 12 *

A. annual_comp
FROM employees;
SELECT last_name, (monthly_salary * 12) + (monthly_commission_pct * 12) AS
B. monthly_commission_pct) AS annual_comp
FROM employees;
SELECT last_name, (monthly_salary + monthly_commission_pct) * 12 AS
C. annual_comp
FROM employees;
SELECT last_name, (monthly_salary * 12) + (monthly_salary * 12 * NVL
D. (monthly_commission_pct, 0)) AS annual_comp
FROM employees;

정답：B
