OFFSET

8min

This article describes using the OFFSET clause to skip a specified number of rows.

Overview

The OFFSET is a clause that skips some records from the result set.

Syntax

The basic syntax of the OFFSET clause is shown below:

Syntax
|
SELECT columns
FROM table_name
OFFSET num;


The parameters and arguments from the syntax are:

  • columns: the columns to be fetched.
  • table_name: a table from which the records will be fetched.
  • OFFSET: a clause that will skip a subset of records.
    • num: the number of records to be skipped.

Example

1) Here, we are creating one new table called oxlafunctions using the CREATE TABLE command and inserting some values into the table using the INSERT command:

Create a table
|
CREATE TABLE oxlafunctions  
(  
    func_name string,   
    func_sub string   
);  

INSERT INTO oxlafunctions   
VALUES
('Numeric', 'ABS'),  
('Numeric', 'CEIL'),  
('String', 'LENGTH'),  
('Numeric', 'SQRT'),  
('Boolean', 'IF'),  
('String', 'STRPOS'),  
('Numeric', 'FLOOR'),  
('String', 'CONCAT'),  
('String', 'LOWER');  


2) To verify that the values have been inserted successfully, retrieve the result set using the command below:

Display the table
|
SELECT * FROM oxlafunctions;

Output
|
+------------+------------+
| func_name  | func_sub   |
+------------+------------+
| Numeric    | ABS        |
| Numeric    | CEIL       |
| String     | LENGTH     |
| Numeric    | SQRT       |
| Boolean    | IF         |
| String     | STRPOS     |
| Numeric    | FLOOR      | 
| String     | CONCAT     |
| String     | LOWER      |
+------------+------------+


3) Use the LIMIT clause in conjunction with the OFFSET clause to skip a subset of records:

Select query
|
SELECT * FROM oxlafunctions
ORDER BY func_name
LIMIT 5 OFFSET 2;


In the above query:

  • The “LIMIT 5” clause is used to fetch only five records.
  • The “OFFSET 2” clause is used to skip the first two records before retrieving the result set of the limit clause.

4) You will get the following output:

Output
|
+------------+------------+
| func_name  | func_sub   |
+------------+------------+
| Boolean    | IF         |
| Numeric    | SQRT       |
| Numeric    | CEIL       |
| Numeric    | ABS        | 
| Numeric    | FLOOR      |
+------------+------------+
