官网的代码，
https://docs.taosdata.com/connector/go/

package main

import (
    "database/sql"
    "fmt"

    _ "github.com/taosdata/driver-go/v3/taosSql"
)

func main() {
    var taosUri = "root:taosdata@tcp(localhost:6030)/"
    taos, err := sql.Open("taosSql", taosUri)
    if err != nil {
        fmt.Println("failed to connect TDengine, err:", err)
        return
    }
}

在测试中，taosUri被随便乱改成错误的地址，如 root:taosdata@tcp(localhost:60301)/， sql.Open("taosSql", taosUri)的返回的 err 一直是 nil 。
本地环境如下：

TDengine-server-3.2.1.0-Linux-x64.deb
github.com/taosdata/driver-go/v3 v3.5.1
golang 1.21.1
