/**
 * Query represents a SELECT SQL statement in a way that is independent of DBMS.
 *
 * Query provides a set of methods to facilitate the specification of different clauses in a SELECT statement. These
 * methods can be chained together.
 *
 * By calling {@see createCommand()}, we can get a {@see Command} instance which can be further used to perform/execute
 * the DB query against a database.
 *
 * For example,
 *
 * ```php
 * $query = new Query;
 * // compose the query
 * $query->select('id, name')
 *     ->from('user')
 *     ->limit(10);
 * // build and execute the query
 * $rows = $query->all();
 * // alternatively, you can create DB command and execute it
 * $command = $query->createCommand();
 * // $command->sql returns the actual SQL
 * $rows = $command->queryAll();
 * ```
 *
 * Query internally uses the {@see QueryBuilder} class to generate the SQL statement.
 *
 * A more detailed usage guide on how to work with Query can be found in the
 * [guide article on Query Builder](guide:db-query-builder).
 *
 * @property string[] $tablesUsedInFrom Table names indexed by aliases. This property is read-only.
