True / False

In MySQL, the LIMIT clause is used to specify the number of records to return in a result set.

True False

The LIMIT clause is used to constrain the number of rows returned by the SELECT statement.

True / False

In MySQL, LIMIT 5 will return the first 5 records of a query result set.

True False

The LIMIT 5 clause tells MySQL to return only the first 5 rows from the result set.

True / False

In MySQL, the LIMIT clause can only be used with the SELECT statement.

True False

The LIMIT clause can also be used with DELETE, UPDATE, and INSERT statements to limit the number of affected rows.

True / False

In MySQL, the LIMIT clause can accept two arguments: the offset and the count.

True False

The LIMIT clause can be used with two arguments where the first argument specifies the offset and the second specifies the count of rows to return.

True / False

In MySQL, LIMIT 5, 10 will return rows 5 to 15.

True False

LIMIT 5, 10 returns 10 rows starting from the sixth row (offset 5), not rows 5 to 15.

True / False

In MySQL, LIMIT 0, 10 and LIMIT 10 are equivalent.

True False

LIMIT 0, 10 explicitly specifies the starting point and number of rows, which is equivalent to just LIMIT 10.

True / False

In MySQL, using LIMIT with ORDER BY can return different results if no ordering is specified.

True False

Without ORDER BY, the rows are returned in an arbitrary order, so LIMIT may yield different results in different executions.

True / False

In MySQL, the LIMIT clause can be used in subqueries to limit the number of rows returned by the subquery.

True False

LIMIT can be used within subqueries to restrict the number of rows that the subquery returns.

True / False

In MySQL, the LIMIT clause can only be used with numeric constants.

True False

The LIMIT clause can use placeholders or expressions as well, especially when used with prepared statements.

Q10

True / False

In MySQL, combining LIMIT with the SQL_CALC_FOUND_ROWS option allows retrieving the total number of rows that would have been returned without LIMIT.

True False

The SQL_CALC_FOUND_ROWS option with LIMIT allows MySQL to calculate the total number of rows that match the query without LIMIT, which can be retrieved with FOUND_ROWS().

Q11

Single Choice

Which of the following MySQL queries will return only the first 5 rows from the employees table?

SELECT * FROM employees LIMIT 5; SELECT * FROM employees LIMIT 0, 5; SELECT * FROM employees LIMIT 5, 0;SELECT * FROM employees LIMIT 1, 5;

The LIMIT clause in MySQL is used to specify the number of rows to return. LIMIT 5 returns the first 5 rows.

Q12

Single Choice

What is the purpose of the LIMIT clause in a MySQL query?

To filter rows based on conditions To restrict the number of rows returned by a query To order rows in ascending orderTo group rows based on a column

The LIMIT clause is used to control the number of rows returned by a MySQL query.

Q13

Single Choice

What does the following MySQL query do?

SQL Code

SELECT * FROM orders LIMIT 10 OFFSET 5;

Returns the first 10 rows starting from the 5th row Returns 10 rows starting from the 6th row Returns the first 5 rows onlyReturns the first 10 rows only

The OFFSET keyword skips the specified number of rows before beginning to return rows. OFFSET 5 skips the first 5 rows, so the result starts from the 6th row.

Q14

Single Choice

What will be the output of the following MySQL query?

SQL Code

SELECT name FROM customers ORDER BY customer_id DESC LIMIT 3;

The first 3 rows in ascending order by customer_id The last 3 rows in descending order by customer_id The first 3 rows in descending order by customer_idThe last 3 rows in ascending order by customer_id

The query orders the results by customer_id in descending order, and LIMIT 3 returns the first 3 rows from that ordered list, which corresponds to the last 3 rows if ordered ascendingly.

Q15

Single Choice

What is the result of the following MySQL query if the products table contains only 3 rows?

SQL Code

SELECT * FROM products LIMIT 5 OFFSET 2;

Returns the first 2 rows Returns the last row Returns all 3 rowsReturns an empty set

OFFSET 2 skips the first 2 rows. Since there are only 3 rows, only the last row will be returned by LIMIT 5.

Q16

Single Choice

What happens when the following MySQL query is executed?

SQL Code

SELECT * FROM employees LIMIT -10;

Returns the first 10 rows Returns all rows Returns the last 10 rowsGenerates a syntax error

The LIMIT clause in MySQL does not accept negative values. Using a negative number results in a syntax error.

Q17

Single Choice

Which MySQL query will return the 11th through 20th rows from the orders table?

SQL Code

SELECT * FROM orders LIMIT 10 OFFSET 10;

SELECT * FROM orders LIMIT 11, 20; SELECT * FROM orders LIMIT 20, 10; SELECT * FROM orders LIMIT 10 OFFSET 10;SELECT * FROM orders OFFSET 11, 20 LIMIT 10;

The LIMIT 10 OFFSET 10 returns the 11th through 20th rows by skipping the first 10 rows and then returning the next 10 rows.

Q18

Single Choice

How can you retrieve rows 51 through 100 from a sales table using MySQL?

SELECT * FROM sales LIMIT 50, 100; SELECT * FROM sales LIMIT 50 OFFSET 50; SELECT * FROM sales LIMIT 100 OFFSET 50;SELECT * FROM sales OFFSET 50 LIMIT 50;

The OFFSET 50 LIMIT 50 skips the first 50 rows and then returns the next 50 rows, corresponding to rows 51 through 100.

Q19

Single Choice

In MySQL, how can you limit the number of rows returned after performing a complex join operation?

SQL Code

SELECT a.name, b.order_id
FROM customers a
JOIN orders b ON a.customer_id = b.customer_id
LIMIT 100;

Add LIMIT before the JOIN clause Use LIMIT within the JOIN clause Add LIMIT at the end of the queryUse LIMIT inside the SELECT clause

The LIMIT clause should be added at the end of the query to limit the number of rows returned by the entire query, including the result of the join.

Q20

Single Choice

A MySQL certification exam question: Given the following query, what will be the effect if there is a FOR UPDATE clause added to it?

SQL Code

SELECT * FROM accounts LIMIT 1 FOR UPDATE;

Locks all rows in the accounts table Locks only the first row returned Locks the first 10 rowsLocks the entire table

The FOR UPDATE clause in MySQL locks the rows that are returned by the SELECT statement. When combined with LIMIT, it will lock only the number of rows specified by LIMIT. In this case, it locks the first row.

Q21

Multiple Choice

Which query retrieves the first 5 records from the 'employees' table?

SQL Code

SELECT *
FROM employees
LIMIT 5;

SELECT * FROM employees LIMIT 5; SELECT * FROM employees LIMIT 1, 5; SELECT * FROM employees WHERE ROWNUM <= 5;SELECT * FROM employees LIMIT 0, 5;

The correct query uses the LIMIT clause to retrieve the first 5 records from the 'employees' table.

Q22

Multiple Choice

FROM sales
LIMIT 5, 10;

SELECT * FROM sales LIMIT 5, 10; SELECT * FROM sales LIMIT 10 OFFSET 5; SELECT * FROM sales LIMIT 10 OFFSET 5;SELECT * FROM sales LIMIT 10;

The correct query skips the first 5 records and retrieves the next 10 records using the LIMIT clause.

Q23

Multiple Choice

Which query retrieves all columns from 'products' but limits the results to 20 records?

SQL Code

SELECT *
FROM products
LIMIT 20;

SELECT * FROM products LIMIT 20; SELECT * FROM products LIMIT 0, 20; SELECT * FROM products WHERE ROWNUM <= 20;SELECT * FROM products LIMIT 10, 20;

The correct query uses the LIMIT clause to restrict the number of rows returned to 20 from the 'products' table.

Q24

Multiple Choice

Determine the correct SQL query to retrieve the first 15 records from the 'orders' table.

SQL Code

SELECT *
FROM orders
LIMIT 15;
