What are the characteristics of ORDER BY sorting in MyS…

The ORDER BY sorting feature in MySQL has the following characteristics:

1. The ORDER BY clause can be used to sort records by one or more columns, with ascending order being the default. You can use the DESC keyword to specify descending order.
2. The ORDER BY clause can be used to sort multiple columns. If multiple columns have the same value, they can be sorted based on the columns that are listed later.
3. The ORDER BY clause can use the alias of a column for sorting.
4. Functions can be used in the ORDER BY clause to sort columns. Functions such as SUM, COUNT, etc. can be used in the ORDER BY clause.
5. The ORDER BY clause can sort in alphabetical order strings. For string columns, sorting is done in alphabetical order.
6. The ORDER BY clause can specify the position of NULL values in sorting using either NULLS FIRST or NULLS LAST. NULLS FIRST will place NULL values at the beginning of the sorting result, while NULLS LAST will place NULL values at the end of the sorting result.
7. The ORDER BY clause can be used in conjunction with the LIMIT clause to retrieve a specified number of sorted results.
8. The ORDER BY clause allows for sorting within a SELECT statement using a subquery.

In conclusion, the ORDER BY clause offers flexible sorting options for customizing sorting requirements using multiple columns, functions, and other options.
