SQL Code

SELECT order_id, customer_id INTO new_orders
FROM orders
WHERE order_date >= '2023-01-01';

SELECT order_id, customer_id INTO new_orders FROM orders WHERE order_date >= '2023-01-01'; SELECT order_id, customer_id FROM orders INTO new_orders WHERE order_date >= '2023-01-01'; INSERT INTO new_orders (order_id, customer_id) SELECT order_id, customer_id FROM orders WHERE order_date >= '2023-01-01';CREATE TABLE new_orders AS SELECT order_id, customer_id FROM orders WHERE order_date >= '2023-01-01';

This SQL statement selects specific columns from the orders table and creates a new table called new_orders containing those columns.

Q23

Multiple Choice

Determine the correct SQL statement to copy data from one table to a new table and rename the columns in the new table.

SQL Code

SELECT order_id AS id, customer_id AS customer INTO renamed_orders
FROM orders;

SELECT order_id AS id, customer_id AS customer INTO renamed_orders FROM orders; SELECT order_id, customer_id INTO renamed_orders (id, customer) FROM orders; SELECT order_id, customer_id INTO renamed_orders AS (id, customer) FROM orders;CREATE TABLE renamed_orders AS SELECT order_id AS id, customer_id AS customer FROM orders;

The SELECT INTO statement is used to copy data to a new table, and the AS keyword allows renaming of columns in the new table.

Q24

Multiple Choice

Which SQL statement correctly uses SELECT INTO to create a backup of a table?

SQL Code

SELECT * INTO backup_orders
FROM orders;

SELECT * INTO backup_orders FROM orders; SELECT INTO backup_orders FROM orders; INSERT INTO backup_orders SELECT * FROM orders;COPY INTO backup_orders FROM orders;

The SELECT INTO statement can be used to create a backup of a table by copying all the data into a new table.

Q25

Multiple Choice

Select the correct SQL statement to create a new table from an existing table with a calculated column using SELECT INTO.

SQL Code

SELECT product_id, price, price * quantity AS total_price
INTO sales_summary
FROM sales;

SELECT product_id, price, price * quantity AS total_price INTO sales_summary FROM sales; SELECT product_id, price, price * quantity INTO sales_summary AS total_price FROM sales; SELECT product_id, price, price * quantity AS total_price FROM sales INTO sales_summary;CREATE TABLE sales_summary AS SELECT product_id, price, price * quantity AS total_price FROM sales;

The SELECT INTO statement allows you to create a new table with a calculated column by using expressions like price * quantity.

Q26

Multiple Choice

Determine the correct SQL statement to create a new table with data from an existing table and apply a condition.

SQL Code

SELECT * INTO recent_orders
FROM orders
WHERE order_date >= '2024-01-01';

SELECT * INTO recent_orders FROM orders WHERE order_date >= '2024-01-01'; SELECT INTO recent_orders * FROM orders WHERE order_date >= '2024-01-01'; SELECT * INTO recent_orders FROM orders WHERE order_date >= '2024-01-01';INSERT INTO recent_orders SELECT * FROM orders WHERE order_date >= '2024-01-01';

The SELECT INTO statement with a WHERE clause allows copying data from one table to a new table, filtered by a specific condition.

Q27

Multiple Choice

Which SQL statement correctly creates a table from an existing table's data using SELECT INTO with an aggregate function?

SQL Code

SELECT customer_id, COUNT(order_id) AS total_orders
INTO customer_summary
FROM orders
GROUP BY customer_id;

SELECT customer_id, COUNT(order_id) AS total_orders INTO customer_summary FROM orders GROUP BY customer_id; SELECT customer_id, COUNT(order_id) INTO customer_summary AS total_orders FROM orders GROUP BY customer_id; SELECT customer_id, COUNT(order_id) INTO customer_summary FROM orders GROUP BY customer_id;INSERT INTO customer_summary SELECT customer_id, COUNT(order_id) AS total_orders FROM orders GROUP BY customer_id;

This SQL statement uses the COUNT aggregate function and GROUP BY to summarize data from the orders table, creating a new table called customer_summary.

Q28

Multiple Choice

Identify the correct SQL statement to create a new table with data from multiple tables using a JOIN and SELECT INTO.

SQL Code

SELECT o.order_id, o.order_date, c.customer_name
INTO order_customer_summary
FROM orders o
JOIN customers c ON o.customer_id = c.customer_id;

SELECT o.order_id, o.order_date, c.customer_name INTO order_customer_summary FROM orders o JOIN customers c ON o.customer_id = c.customer_id; SELECT o.order_id, o.order_date, c.customer_name FROM orders o JOIN customers c ON o.customer_id = c.customer_id INTO order_customer_summary; INSERT INTO order_customer_summary SELECT o.order_id, o.order_date, c.customer_name FROM orders o JOIN customers c ON o.customer_id = c.customer_id;SELECT INTO order_customer_summary o.order_id, o.order_date, c.customer_name FROM orders o JOIN customers c ON o.customer_id = c.customer_id;

The SELECT INTO statement can be used to create a new table with combined data from multiple tables using a JOIN operation.

Q29

Multiple Choice

SELECT order_id, order_date INTO temp_orders
FROM orders;
RENAME TABLE temp_orders TO archive_orders;

SELECT order_id, order_date INTO temp_orders FROM orders; RENAME TABLE temp_orders TO archive_orders; SELECT order_id, order_date INTO archive_orders FROM orders; SELECT order_id, order_date INTO temp_orders FROM orders; ALTER TABLE temp_orders RENAME TO archive_orders;INSERT INTO archive_orders (order_id, order_date) SELECT order_id, order_date FROM orders;

This SQL statement first creates a new table with selected columns using SELECT INTO, then renames the newly created table.

Q30

Multiple Choice

Determine the correct SQL statement to create a new table with a WHERE clause that filters data using a subquery.

SQL Code

SELECT * INTO filtered_orders
FROM orders
WHERE customer_id IN (SELECT customer_id
FROM customers
WHERE customer_status = 'Active');

SELECT * INTO filtered_orders FROM orders WHERE customer_id IN (SELECT customer_id FROM customers WHERE customer_status = 'Active'); SELECT INTO filtered_orders * FROM orders WHERE customer_id IN (SELECT customer_id FROM customers WHERE customer_status = 'Active'); INSERT INTO filtered_orders SELECT * FROM orders WHERE customer_id IN (SELECT customer_id FROM customers WHERE customer_status = 'Active');CREATE TABLE filtered_orders AS SELECT * FROM orders WHERE customer_id IN (SELECT customer_id FROM customers WHERE customer_status = 'Active');

The SELECT INTO statement allows you to create a new table with data filtered by a subquery, which can be used in the WHERE clause.
