/**
 * Represents an SQL statement to execute in a database.
 *
 * It's usually created by calling {@see \Yiisoft\Db\Connection\ConnectionInterface::createCommand()}.
 *
 * You can get the SQL statement it represents via the {@see getSql()} method.
 *
 * To execute a non-query SQL (such as `INSERT`, `DELETE`, `UPDATE`), call {@see execute()}.
 *
 * To execute a SQL statement that returns a result (such as `SELECT`), use {@see queryAll()}, {@see queryOne()},
 * {@see queryColumn()}, {@see queryScalar()}, or {@see query()}.
 *
 * For example,
 *
 * ```php
 * $users = $connectionInterface->createCommand('SELECT * FROM user')->queryAll();
 * ```
 *
 * Abstract command supports SQL prepared statements and parameter binding.
 *
 * Call {@see bindValue()} to bind a value to a SQL parameter.
 * Call {@see bindParam()} to bind a PHP variable to a SQL parameter.
 *
 * When binding a parameter, the SQL statement is automatically prepared. You may also call {@see prepare()} explicitly
 * to do it.
 *
 * Abstract command supports building some SQL statements using methods such as {@see insert()}, {@see update()}, {@see delete()},
 * etc.
 *
 * For example, the following code will create and execute an `INSERT` SQL statement:
 *
 * ```php
 * $connectionInterface->createCommand()->insert(
 *     'user',
 *     ['name' => 'Sam', 'age' => 30],
 * )->execute();
 * ```
 *
 * To build `SELECT` SQL statements, please use {@see QueryInterface} and its implementations instead.

30			* Represents an SQL statement to execute in a database.
31			*
32			* It's usually created by calling {@see \Yiisoft\Db\Connection\ConnectionInterface::createCommand()}.
33			*
34			* You can get the SQL statement it represents via the {@see getSql()} method.
35			*
36			* To execute a non-query SQL (such as `INSERT`, `DELETE`, `UPDATE`), call {@see execute()}.
37			*
38			* To execute a SQL statement that returns a result (such as `SELECT`), use {@see queryAll()}, {@see queryOne()},
39			* {@see queryColumn()}, {@see queryScalar()}, or {@see query()}.
40			*
41			* For example,
42			*
43			* ```php
44			* $users = $connectionInterface->createCommand('SELECT * FROM user')->queryAll();
45			* ```
46			*
47			* Abstract command supports SQL prepared statements and parameter binding.
48			*
49			* Call {@see bindValue()} to bind a value to a SQL parameter.
50			* Call {@see bindParam()} to bind a PHP variable to a SQL parameter.
51			*
52			* When binding a parameter, the SQL statement is automatically prepared. You may also call {@see prepare()} explicitly
53			* to do it.
54			*
55			* Abstract command supports building some SQL statements using methods such as {@see insert()}, {@see update()}, {@see delete()},
56			* etc.
57			*
58			* For example, the following code will create and execute an `INSERT` SQL statement:
59			*
60			* ```php
61			* $connectionInterface->createCommand()->insert(
62			* 'user',
63			* ['name' => 'Sam', 'age' => 30],
64			* )->execute();
65			* ```
66			*
67			* To build `SELECT` SQL statements, please use {@see QueryInterface} and its implementations instead.
