Type '\c' to clear the current input statement. mysql> ``` 为了与所有MySQL客户端兼容,建议使用以下命令指定用户密码 [双SHA1](../operations/settings/settings-users.md#password_double_sha1_hex) 在配置文件中。 如果使用用户密码指定 [SHA256](../operations/settings/settings-users.md#password_sha256_hex),一些客户端将无法进行身份验证(mysqljs和旧版本的命令行工具mysql)。 限制: - 不支持准备好的查询 - 某些数据类型以字符串形式发送 [原始文章](https://clickhouse.tech/docs/en/interfaces/mysql/)
