Limit - (MySQL Misc)

In MySQL, the LIMIT keyword is used to specify the maximum number of records to return from a query. In this tutorial, we'll discuss how to use the LIMIT keyword in MySQL.

Syntax

The syntax for the LIMIT keyword in MySQL is:

SELECT column1, column2, ...
FROM table
LIMIT [offset,] count;

The offset parameter specifies the number of records to skip before starting to return records. The count parameter specifies the maximum number of records to return.

Example

Suppose we have a table called "students" with columns "id", "name", and "age", and we want to retrieve the first five records from the table. Here's how we can use the LIMIT keyword:

SELECT id, name, age
FROM students
LIMIT 5;

This query will return the first five records from the "students" table.

Output

When we run the example query above, the output will be a table of the first five records from the "students" table with columns "id", "name", and "age".

Explanation

In the example above, we used the LIMIT keyword to specify that we wanted to retrieve only the first five records from the "students" table. By default, the LIMIT keyword returns records starting from the first record in the result set (i.e., offset is set to 0).

Use

The LIMIT keyword is useful when you want to retrieve a specific number of records from a query result set. This is useful when you want to limit the amount of data returned by a query and improve the performance of your application.

Important Points

  • The LIMIT keyword can be used with the SELECT statement or any other statement that returns a result set, such as the UPDATE or DELETE statements.
  • You can use the LIMIT keyword without specifying an offset value if you only want to specify a maximum number of records to return.
  • The LIMIT keyword works in conjunction with the ORDER BY keyword to sort the result set before limiting the number of records returned.

Summary

In this tutorial, we discussed how to use the LIMIT keyword in MySQL to limit the number of records returned by a query. We covered the syntax, example, output, explanation, use, and important points of the LIMIT keyword. With this knowledge, you can now retrieve a specific number of records from a query result set in MySQL.
