```
Type: string
Valid Values: <name>
Default: utf8_general_ci
Default: utf8mb4_general_ci
```

Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.

A list of valid charsets for a server is retrievable with `SHOW COLLATION`.

The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5. You should use older collation (e.g. `utf8_general_ci`) for older MySQL.

Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)).
