Convert DateTime in C# to yyyy-MM-dd format and Store it to MySql DateTime Field

Convert DateTime in C# to yyyy-MM-dd format and Store it to MySql DateTime Field

To convert a DateTime value to a yyyy-MM-dd format in C# and store it in a MySQL DATETIME field, you can use the ToString method to format the date and pass the formatted string to a MySqlParameter object.

Here's an example:

using MySql.Data.MySqlClient; // Create a connection to the database using (var connection = new MySqlConnection("connection_string")) { connection.Open(); // Create a command to insert the date value into the database using (var command = new MySqlCommand("INSERT INTO my_table (my_date_column) VALUES (@myDate)", connection)) { // Set the parameter value to the formatted date string var myDate = DateTime.Now.ToString("yyyy-MM-dd"); command.Parameters.AddWithValue("@myDate", myDate); // Execute the command command.ExecuteNonQuery(); } }

In this example, we create a MySqlConnection object to connect to the MySQL database, and then create a MySqlCommand object to insert a date value into the my_table table. We use the @myDate parameter to specify the value of the my_date_column column.

We then use the DateTime.Now property to get the current date and time, and call the ToString method with the yyyy-MM-dd format string to get a string representation of the date in the desired format. We pass this string to the AddWithValue method of the MySqlCommand object to set the value of the @myDate parameter.

Finally, we call the ExecuteNonQuery method of the MySqlCommand object to execute the SQL command and insert the date value into the database.
