错误sql：将varchar数据类型转换为datetime数据类型导致超出范围值

问题描述

我尝试使用以下代码输入当天的日期：

I tried to enter the date of the current day with the following code:

string now = (DateTime.Today.Day + "/" + DateTime.Today.Month + "/" + DateTime.Today.Year).ToString();
string tm = (DateTime.Today.Hour + ":" + DateTime.Today.Minute).ToString();
string sql2 = string.Format("INSERT INTO Kabala2 (Nu_kabala,Ma_num,Sk,Seif_hacnasa,Seif_name,Date) VALUES('{0}','{1}','{2}','{3}','{4}','{5}')", n, Session["Ma_num"], lprice, lkod,des, now );
Dal.DoQuery(sql2);

当我运行此代码时，会显示标题中的错误：

when I run this code it shows me the error in the title :

我该如何解决？

------------------编辑

------------------edit

我将其更改为： string now = DateTime.Today.ToString（yyyy-MM-dd HH：mm：ss）; ，它的工作原理

i changed it to:string now = DateTime.Today.ToString("yyyy-MM-dd HH:mm:ss"); and it works.

现在我有另一个问题，当我运行下面的代码显示错误：将数据类型varchar转换为数字错误。

now i have another problem, when i run the code below it shows me the error:Error converting data type varchar to numeric.

string now = DateTime.Today.ToString("yyyy-MM-dd HH:mm:ss");
    string tm = DateTime.Now.ToString("HH:mm:ss");
    string sql = string.Format("INSERT INTO Kabala1 (Nu_kabala,Ma_num,Date,Time,Total,Status,Name,User_n) VALUES('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}')", n, Session["Ma_num"], now, tm, lprice, "ddffs", Session["user"], "ddffs");
    Dal.DoQuery(sql);
    string sql2 = string.Format("INSERT INTO Kabala2 (Nu_kabala,Ma_num,Sk,Seif_hacnasa,Seif_name,Date) VALUES('{0}','{1}','{2}','{3}','{4}','{5}')", n, Session["Ma_num"], lprice, lkod, des, now);
    Dal.DoQuery(sql2);
    string sql3 = string.Format("INSERT INTO Kabala3 ((Nu_kabala,Msd,Ma_num,Kind_pay,Name_pay,Date_pay,Sk,Ms_sek,Snif,Bank,Date_klita,Seif) VALUES('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}')", n,"1", Session["Ma_num"],"13", "ddffds", now, lprice, this.card.Text, this.mm.Text, this.yy.Text, now, lkod);
    Dal.DoQuery(sql3);

推荐答案

您可以使用 DateTime.Today.ToString（yyyy-MM-dd HH：mm：ss） //无论什么格式...

You can Use DateTime.Today.ToString("yyyy-MM-dd HH:mm:ss") //Whatever format...

或者使用CONVERT方法直接使用sql语法是

or Use direct sql instead using CONVERT method. Syntax is

CONVERT(VARCHAR,DateTime.Today.Day + "/" + DateTime.Today.Month + "/" + DateTime.Today.Year,103)

CONVERT(VARCHAR, DateTime.Today.Hour + ":" + DateTime.Today.Minute + ":00" ,108)

必须提供格式hh：mm：ss

whould give format of hh:mm:ss
