Question

如何提供MSSQL连接？它说它总是与代码联系在一起。即使信息不正确，也不会出错。

package main

import (
    "database/sql"
    "fmt"
    _ "github.com/denisenkom/go-mssqldb"
    "log"
)

var server = "DESKTOP\\SQLEXPRESS"
var port = 1433
var user = "loginx"
var password = "1"
var database = "test"

var db *sql.DB

func main() {
    var err error

    connString := fmt.Sprintf("server=%s;user id=%s;password=%s;port=%d;database=%s;",
        server, user, password, port, database)
    fmt.Println(server, user, password, database)
    conn, err := sql.Open("mssql", connString)
    if err != nil {
        log.Fatal("Open connection failed:", err.Error())
    }
    fmt.Printf("Connected!\n")
    defer conn.Close()

}

Open（）中的

mssql应该是sqlserver

尝试更改此内容。

db, err = sql.Open("sqlserver", connString)

所以您的main（）看起来像..

var db *sql.DB

func main() {
    var err error

    // Create connection string
    connString := fmt.Sprintf("server=%s;user id=%s;password=%s;port=%d",
        server, user, password, port)

    // Create connection pool
    db, err = sql.Open("sqlserver", connString)
    if err != nil {
        log.Fatal("Error creating connection pool: " + err.Error())
    }
    log.Printf("Connected!\n")

    // Close the database connection pool after program executes
    defer db.Close()
}
