`SELECT` is a SQL command used to retrieve data from one or more tables in a database. It allows you to specify which columns to retrieve, which table(s) to retrieve them from, and any filtering or sorting criteria to apply to the data. The basic syntax of the `SELECT` statement is:
```
SELECT column1, column2, ...
FROM table_name
WHERE condition
ORDER BY column1, column2, ... ASC|DESC;
```
The `FROM` clause specifies the table(s) to retrieve data from, the `WHERE` clause specifies any conditions that must be met for a row to be included in the result set, and the `ORDER BY` clause specifies how the results should be sorted. The `ASC` keyword sorts the results in ascending order, while the `DESC` keyword sorts them in descending order.
