go连接ClickHouse, 响应 driver: bad connection,通过客户端能连上,不知是否与驱动版本有关

Question

采用官方最简单的例子，始终不行, 希望有经验的大佬帮忙看下，感谢
go.mod

module ck-test

go 1.16

require (
    github.com/ClickHouse/clickhouse-go v1.4.1
    github.com/jmoiron/sqlx v1.2.1-0.20200614204820-f5f08a7e27f6
)

main.go

package main

import (
    _ "github.com/ClickHouse/clickhouse-go"
    "github.com/jmoiron/sqlx"
)


func main()  {
    connect, err := sqlx.Open("clickhouse", "tcp://127.0.0.1:9000?debug=true&read_timeout=10&write_timeout=10")
    if err != nil {
        panic(err)
    }
    var items []interface{}

    sql := "select * from statics.mysql_slow_log";

    if err := connect.Select(&items, sql); err != nil {
        panic(err)
    }

}

异常：

Answer 1

database=default, username=default ？

你不填具体的库名，也没有用户名，密码？

Answer 2

本地的9000端口是否正常，下个客户端连一下8123看下，服务是否正常启动
