将日期时间从C＃插入到SqlServer [英] Inserting datetime from C# to SqlServer

问题描述

我将日期时间从C＃插入到SqlServer。但格式不兼容。



我尝试使用DateTime.Now。但是它给出了错误。



请帮忙？

Hi,

I am inserting datetime from C# to SqlServer. But format is not compatible.

I tried using DateTime.Now. But it is giving error.

Please help?

推荐答案

使用参数化查询插入它，并且它将自行排序 - 以及更安全（参见SQL注入攻击）。 Google SQLCommand.AddWithValue并使用它而不是在SQL命令字符串中包含DateTime.Now。

Insert it with a parametrised query, and it will sort itself out - as well as being safer (see SQL Injection attack). Google SQLCommand.AddWithValue and use that instead of including the DateTime.Now in your SQL command string.

你能给出一个例子，输入多个参数插入。

Can you give an example with entering more than one parameter insertion takes place.

SqlConnection conn = new SqlConnection("your connection string");
SqlCommand cmd = new SqlCommand("INSERT INTO table_name (username, logindate) VALUES (@USERNAME, @DATE)", conn);
cmd.Parameters.AddWithValue("@USERNAME", tbUserName.Text);
cmd.Parameters.AddWithValue("@DATE", DateTime.Now);
int i = cmd.ExecuteNonQuery();

ok试试这个

abc datetime，.......

abc是一列

ok try this

private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                string a = DateTime.Now.ToShortDateString();
                string Query = "Insert into ab values('" + a + "')";
                string con = "Data source =abc; initial catalog=ex;            integrated security= true";
                SqlConnection cn = new SqlConnection(con);
                cn.Open();
                SqlCommand cmd = new SqlCommand( Query ,cn);
                cmd.ExecuteNonQuery();
               
            }
            catch (Exception g)
            {
                label1.Text = g.Message;
            }
        }
