The LIMIT clause in MySQL is used in conjunction with the SELECT statement to limit the number of rows returned in the result set. The Limit Clause accepts one or two offset and count arguments. Both arguments can have zero or positive integer values.

A SQL SELECT query with the ORDER BY clause returns a result set with the rows sorted by the values of one or more columns. Expressions like as column names, user-defined functions, arithmetic operations, and CASE expressions can be used as sort criteria.

The ORDER BY keyword in MySQL is:

To sort the result set in ascending or descending order, use the ORDER BY keyword. By default, the ORDER BY keyword organises the records in ascending order. Use the DESC keyword to sort the records in descending order.
