Question

我有这个备份代码，我想每月执行一次，我熟悉在sql server management studio中使用作业或维护计划，但我想编写代码而不是使用sql server作业或维护计划。

的.aspx

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Add" CssClass="btn btn-success btn-lg" />

aspx.cs

protected void Button111_Click(object sender, EventArgs e)
{

    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["mycon"].ToString());

    string backupDIR = "C:\backup";
    if (!System.IO.Directory.Exists(backupDIR))
    {
        System.IO.Directory.CreateDirectory(backupDIR);
    }
    try
    {
        con.Open();
        sqlcmd = new SqlCommand("backup database iporma to disk= '" + backupDIR + "\" + DateTime.Now.ToString("ddMMyy_HHss") + ".Bak'", con);
        sqlcmd.ExecuteNonQuery();
        con.Close();
        lblError.Text = "Completed";


    }

    catch (Exception ex)
    {
        lblError.Text = "Error" + ex.ToString();
    }

}

请放轻松我，我还是新手。

Answer 1

创建Windows服务或Windows计划任务以执行此代码。您将在Google上找到有关如何创建Windows服务的好文章。

Answer 2

您的代码是正确的查询更改：您需要一个月然后您应该只使用MMM或mMm：

 sqlcmd = new SqlCommand("backup database iporma to disk= '" + backupDIR + "\" + DateTime.Now.ToString("MMM") + ".Bak'", con);

Answer 3

include("connection.php");
if (isset($_POST['search'])) {
    $valueToSearch= mysqli_real_escape_string($connect,$_POST['valueToSearch']);
    $query="SELECT * FROM table_name WHERE Student_Name LIKE '%$valueToSearch%'";
    $search_result=filterTable($query,$connect);

}
else{
    $query="SELECT * FROM table_name";
    $search_result=filterTable($query,$connect);
}
function filterTable($query,$connect)
{

    $filter_Result=mysqli_query($connect,$query);
    if (!$filter_Result) {
        die('query is not valid '.mysqli_error($connect));
    }
    else{
        return $filter_Result;
    }

}

每月执行代码
