C＃-ASP.NET-将日历中的日期插入数据库

Question

我试图将用户选择的日历中的日期存储到数据库中。 似乎没有将其插入到Access数据库中。 DB字段数据类型为日期/时间，变量在下面。 我知道我的查询有效，因为其他信息可以正确存储。

DateTime dtUserDate;
dtUserDate = calenderUserDate.SelectedDate;

string myQuery = "INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, Date Joined)   VALUES ( '" + strName + "' , '" + strEmail + "' , '" + strAddress + "' , '" + strTown + "' , '" + strCounty + "' , '" + strPostCode + "' , '" + strCountry + "' , '" + strTeleNumber + "' , '" + dtUserDate+ "')";

谢谢

Answer 1

尝试

INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, [Date Joined]) ....

请注意，您的表列“ Date Joined有空格，请使用[Date Joined]

使用参数如下

string myQuery = "INSERT INTO MMK( Name, Email, Address, Town, County, PostCode, Country, Telephone, [Date Joined])   VALUES ( ?, ?, ?, ?, ?, ?, ?, ?, ?)";
using (var cmd = new OleDbCommand(myQuery, con))
{
    cmd.Parameters.AddWithValue("Name", strName);
    ....
    cmd.Parameters.AddWithValue("DateJoined", dtUserDate);
