无法连接到MS SQL

Question

我正在玩Golang并尝试连接到MS SQL。我正在使用github.com/denisenkom/go-mssqldb包和sqlx来实现此目的。 但我收到错误：Unable to open tcp connection with host 'localhost:1433': dial tcp [::1]:1433: connectex: No connection could be made because the target machine actively refused it 我完全确定数据库本身的一切，因为它与my.Net项目完美配合。 这是代码：

package main

import (
    "database/sql"
    "fmt"
    "log"

    _ "github.com/denisenkom/go-mssqldb"
    "github.com/jmoiron/sqlx"
)

type Excursion struct {
    Id   int            `db:"id"`
    Name sql.NullString `db:"name"`
}

func main() {
    db, err := sqlx.Connect("sqlserver", "server=localhost;user id=DESKTOP-H74S9IT\\andrey.shedko;database=Flex;connection timeout=30;")
    if err := db.Ping(); err != nil {
        log.Fatal(err)
    }
    rows, err := db.Queryx("SELECT Id, Name FROM dbo.Excursions")
    for rows.Next() {
        var item Excursion
        err = rows.StructScan(&item)
        if err != nil {
            log.Fatal(err)
        }
        fmt.Printf(
            "%d - %s:  %s\n===================\n",
            item.Id,
            item.Name.String,
        )
    }
    defer db.Close()
}

你能告诉我这有什么问题吗？

可能你需要激活TCP。
