What does ‘limit 1’ mean in MySQL?

In MySQL, LIMIT 1 is a statement used to restrict the number of rows returned in a query. When using LIMIT 1, it means only the first row of the query result set will be returned.

This feature is often very useful when you need to query a specific single row or only operate on the first row of the result set. By combining other conditions and sorting methods, you can accurately retrieve the single row data you want.

Example usage:

SELECT * FROM your_table LIMIT 1;

The query above will retrieve the data from the first row of the your_table table. If no conditions are specified, MySQL will determine the first row of data returned based on the storage order of the table data.
