# MySQL {#mysql}
Uzak bir MySQL sunucusunda veritabanları na bağlanmak ve gerçekleştirmek için izin verir `INSERT` ve `SELECT` ClickHouse ve MySQL arası nda veri alı şverişi için sorgular.
Bu `MySQL` veritabanı motoru sorguları MySQL sunucusuna çevirir, böylece aşağı daki gibi işlemleri gerçekleştirebilirsiniz `SHOW TABLES` veya `SHOW CREATE TABLE` .
Aşağı daki sorguları gerçekleştiremiyor:
- `RENAME`
- `CREATE TABLE`
- `ALTER`
## Veritabanı oluşturma {#creating-a-database}
``` sql
CREATE DATABASE [IF NOT EXISTS] db_name [ON CLUSTER cluster]
ENGINE = MySQL('host:port', ['database' | database], 'user', 'password')
```
**Motor Parametreleri**
- `host:port` — MySQL server address.
- `database` — Remote database name.
- `user` — MySQL user.
- `password` — User password.

MySQL tablo:
``` text
mysql> USE test;
Database changed
mysql> CREATE TABLE `mysql_table` (
-> `int_id` INT NOT NULL AUTO_INCREMENT,
-> `float` FLOAT NOT NULL,
-> PRIMARY KEY (`int_id`));
Query OK, 0 rows affected (0,09 sec)
mysql> insert into mysql_table (`int_id`, `float` ) VALUES (1,2);
Query OK, 1 row affected (0,00 sec)
mysql> select * from mysql_table;
+------+-----+
| int_id | value |
+------+-----+
| 1 | 2 |
+------+-----+
1 row in set (0,00 sec)
```
