OFFSET for pagination in SQL

Introduction

OFFSET helps you skip a certain number of rows in a list, so you can see the next set of results, like turning pages in a book.

When showing search results page by page on a website.

When displaying a list of items in chunks instead of all at once.

When you want to load more data as the user scrolls down.

When you need to jump to a specific page of results in a report.

Syntax

SQL

SELECT column1, column2 FROM table_name ORDER BY column1 OFFSET number_of_rows_to_skip ROWS;

OFFSET must be used with ORDER BY to ensure consistent results.

OFFSET skips the first N rows and returns the rest.

Examples

Skip the first 5 employees and show the rest ordered by name.

SQL

SELECT name FROM employees ORDER BY name OFFSET 5 ROWS;

Skip the first 10 books and show the rest ordered by id.

SQL

SELECT id, title FROM books ORDER BY id OFFSET 10 ROWS;

Skip the first 20 products sorted by price.

SQL

SELECT * FROM products ORDER BY price OFFSET 20 ROWS;

Sample Program

This creates a table of fruits, inserts 7 fruits, then selects all fruits skipping the first 3 by id order.

SQL

CREATE TABLE fruits (id INT, name VARCHAR(20));
INSERT INTO fruits VALUES (1, 'Apple'), (2, 'Banana'), (3, 'Cherry'), (4, 'Date'), (5, 'Elderberry'), (6, 'Fig'), (7, 'Grape');
SELECT id, name FROM fruits ORDER BY id OFFSET 3 ROWS;

Important Notes

OFFSET alone does not limit how many rows you get; it just skips rows.

Use OFFSET with LIMIT (or FETCH) to get a fixed number of rows after skipping.

Without ORDER BY, OFFSET may return unpredictable results.

Summary

OFFSET skips a set number of rows in query results.

Always use ORDER BY with OFFSET for consistent paging.

Combine OFFSET with LIMIT to control page size.

Practice

1. What does the OFFSET clause do in an SQL query?

easy

A. It skips a specified number of rows before returning the result set.

B. It limits the number of rows returned by the query.

C. It sorts the rows in ascending order.

D. It groups rows based on a column.

Solution

1. Step 1: Understand OFFSET purpose

   The OFFSET clause tells SQL to skip a certain number of rows before starting to return rows.

2. Step 2: Compare with other clauses

   LIMIT controls how many rows to return, ORDER BY sorts rows, GROUP BY groups rows. OFFSET specifically skips rows.

3. Final Answer:

   It skips a specified number of rows before returning the result set. -> Option A

4. Quick Check:

   OFFSET = skip rows [OK]

Hint: OFFSET skips rows; LIMIT controls count [OK]

Common Mistakes:

• Confusing OFFSET with LIMIT
• Thinking OFFSET sorts rows
• Assuming OFFSET groups rows

2. Which of the following is the correct syntax to skip the first 10 rows in a query?

easy

A. SELECT * FROM table OFFSET;

B. SELECT * FROM table SKIP 10;

C. SELECT * FROM table LIMIT 10 OFFSET;

D. SELECT * FROM table OFFSET 10;

Solution

1. Step 1: Recall OFFSET syntax

   The correct syntax is to write OFFSET followed by the number of rows to skip, e.g., OFFSET 10.

2. Step 2: Check each option

   SELECT * FROM table OFFSET 10; uses correct syntax. SELECT * FROM table SKIP 10; uses SKIP which is invalid. SELECT * FROM table LIMIT 10 OFFSET; misplaces OFFSET. SELECT * FROM table OFFSET; lacks a number.

3. Final Answer:

   SELECT * FROM table OFFSET 10; -> Option D

4. Quick Check:

   OFFSET number correct syntax [OK]

Hint: Use OFFSET number after FROM clause [OK]

Common Mistakes:

• Using SKIP instead of OFFSET
• Omitting the number after OFFSET
• Placing OFFSET before FROM

3. Given the table Employees with columns id and name, what will this query return?

SELECT id, name FROM Employees ORDER BY id ASC LIMIT 3 OFFSET 2;

medium

A. Rows with the first 3 employees ordered by id.

B. Rows 1, 2, and 3 ordered by id ascending.

C. Rows 3, 4, and 5 ordered by id ascending.

D. Rows 2, 3, and 4 ordered by id ascending.

Solution

1. Step 1: Understand OFFSET and LIMIT effect

   OFFSET 2 skips the first 2 rows. LIMIT 3 returns the next 3 rows after skipping.

2. Step 2: Apply ORDER BY

   Rows are ordered by id ascending, so rows with id 3, 4, and 5 are returned.

3. Final Answer:

   Rows 3, 4, and 5 ordered by id ascending. -> Option C

4. Quick Check:

   OFFSET 2 skips first 2, LIMIT 3 returns next 3 [OK]

Hint: OFFSET skips rows, LIMIT picks next rows [OK]

Common Mistakes:

• Ignoring OFFSET and returning first rows
• Confusing OFFSET number with LIMIT
• Not applying ORDER BY before OFFSET

4. Identify the error in this query:

SELECT * FROM Products LIMIT 5 OFFSET;

medium

A. LIMIT cannot be used with OFFSET.

B. OFFSET requires a number after it.

C. SELECT * is not allowed with OFFSET.

D. OFFSET must come before LIMIT.

Solution

1. Step 1: Check OFFSET syntax

   OFFSET must be followed by a number indicating how many rows to skip.

2. Step 2: Analyze the query

   The query ends with OFFSET but no number is given, causing a syntax error.

3. Final Answer:

   OFFSET requires a number after it. -> Option B

4. Quick Check:

   OFFSET needs number [OK]

Hint: Always put a number after OFFSET [OK]

Common Mistakes:

• Leaving OFFSET without a number
• Thinking OFFSET must come before LIMIT
• Believing SELECT * disallows OFFSET

5. You want to display page 4 of a product list with 20 items per page, ordered by created_at descending. Which query correctly uses OFFSET and LIMIT?

hard

A. SELECT * FROM Products ORDER BY created_at DESC LIMIT 20 OFFSET 60;

B. SELECT * FROM Products ORDER BY created_at DESC LIMIT 20 OFFSET 80;

C. SELECT * FROM Products ORDER BY created_at DESC LIMIT 4 OFFSET 20;

D. SELECT * FROM Products ORDER BY created_at DESC OFFSET 20 LIMIT 4;

Solution

1. Step 1: Calculate OFFSET for page 4

   Each page has 20 items, so page 4 starts after 3 pages: 3 * 20 = 60 rows skipped.

2. Step 2: Check LIMIT and OFFSET usage

   LIMIT 20 returns 20 rows, OFFSET 60 skips first 60 rows, so page 4 shows rows 61-80.

3. Step 3: Verify ORDER BY

   ORDER BY created_at DESC ensures newest products first, consistent paging.

4. Final Answer:

   SELECT * FROM Products ORDER BY created_at DESC LIMIT 20 OFFSET 60; -> Option A

5. Quick Check:

   Page 4 offset = 60, limit = 20 [OK]

Hint: OFFSET = (page-1)*page_size, LIMIT = page_size [OK]

Common Mistakes:

• Calculating OFFSET as page*page_size
• Swapping LIMIT and OFFSET values
• Omitting ORDER BY for consistent paging
