/**
 * Command represents a SQL statement to be executed against a Sphinx.
 *
 * A command object is usually created by calling [[Connection::createCommand()]].
 * The SQL statement it represents can be set via the [[sql]] property.
 *
 * To execute a non-query SQL (such as INSERT, REPLACE, DELETE, UPDATE), call [[execute()]].
 * To execute a SQL statement that returns result data set (such as SELECT, CALL SNIPPETS, CALL KEYWORDS),
 * use [[queryAll()]], [[queryOne()]], [[queryColumn()]], [[queryScalar()]], or [[query()]].
 * For example,
 *
 * ~~~
 * $articles = $connection->createCommand("SELECT * FROM `idx_article` WHERE MATCH('programming')")->queryAll();
 * ~~~
 *
 * Command supports SQL statement preparation and parameter binding just as [[\yii\db\Command]] does.
 *
 * Command also supports building SQL statements by providing methods such as [[insert()]],
 * [[update()]], etc. For example,
 *
 * ~~~
 * $connection->createCommand()->update('idx_article', [
 *     'genre_id' => 15,
 *     'author_id' => 157,
 * ])->execute();
 * ~~~
 *
 * To build SELECT SQL statements, please use [[Query]] and [[QueryBuilder]] instead.
