format string in datetime c# to insert in MYSQL datetime column

Question

I have code like this:

AutoParkDataDataContext Db = new AutoParkDataDataContext();
Dailyreport dailyRep = new Dailyreport();
string time = Convert.ToDateTime("10-10-2014 15:00:00");
dailyRep.order_time = time;
Db.Dailyreports.InsertOnSubmit(dailyRep);
Db.SubmitChanges();

When I see it in the DailyReport table it shows me only the date ("10-10-2014 00:00:00:00") , so the time is ignored. How could i fix it? The column type is DateTime .

Answer 1

A quick/easy method to insert date or datetime into MySQL is to use the format 'yyyy-MM-dd', or datetime as 'yyyy-MM-dd H:mm:ss'.

Try this

DateTime theDate = DateTime.Now;
theDate.ToString("yyyy-MM-dd H:mm:ss");

Make your SQL look like this.

insert into mytable (date_time_field) value ('2013-09-09 03:44:00');

Answer 2

Your line:

string time = Convert.ToDateTime("10-10-2014 15:00:00");

Shouldn't compile.

I can only guess that you don't have DateTime as type of your column in SQL Server, you should modify it to keep DateTime and then pass a DateTime type object, not a string.

Answer 3

This means that the underlying data type in the database must be Date . Change that to DateTime and it will store the time as well.

Answer 4

DateTime dateTimeVariable = DateTime.Now;
string date = dateTimeVariable.ToString("yyyy-MM-dd H:mm:ss");

The insert Statement will look kind of like this:

string InsertQuery   = "INSERT INTO table( `fieldName` ) VALUES ( '" + date + "' )";
