使用 execContext golang 插入时出错

Question

我有处理将新数据插入数据库的代码mysql，我已经设置了正确的上下文、查询语句和值参数。但是当我尝试执行查询时，出现了这样的错误

sql: expected 1 arguments, got 6

这是我的driver

"github.com/go-sql-driver/mysql"

这是我的数据库连接语句

connResult, err := sql.Open("mysql", os.Getenv("MY_SQL_URL"))

这是我的代码

func (pr productRepo) AddProduct(c *gin.Context, req product.AddProduct) *model.RepoResponse {
    var negotiate int8
    ctx, cancel := context.WithTimeout(c, 10*time.Second)
    identity := library.Identity(c)
    currentTime := library.Time().CurrentDateTimeDbFormat()

    defer cancel()

    id := uuid.New()
    if req.Negotiate {
        negotiate = 1
    }
    statement := "INSERT INTO product (id_product, user, field, judul, negosiasi, createdAt) VALUES ('?', '?', '?', '?', ?, '?')"

    result, errInsert := pr.conn.ExecContext(ctx, statement, id, identity.GetUserID(), req.Field, req.Title, negotiate, currentTime)
    if errInsert != nil {
        fmt.Println(errInsert)
        return &model.RepoResponse{Success: false, Msg: "Failed to add product"}
    }

    inserted, errRows := result.RowsAffected()
    if errRows != nil {
        fmt.Println(errRows)
        return &model.RepoResponse{Success: false, Msg: "Failed to add product"}
    } else if inserted == 0 {
        fmt.Println("Inserted value ", inserted)
        return &model.RepoResponse{Success: false, Msg: "Failed to add product"}
    }
    return &model.RepoResponse{Success: true, Data: id}
}

我的代码有问题还是来自我的 driver？谢谢

试着把问号放在没有撇号的语句中：

statement := "INSERT INTO product (id_product, user, field, judul, negosiasi, createdAt) VALUES (?, ?, ?, ?, ?, ?)"

如您所见，在您的代码中只有一个 ? 没有撇号，因此驱动程序需要一个 arg 而不是六个
