Subsonic ignoring TimeSpan property

Question

For some reason the TimeSpan property on my class is not being persisted into the database by Subsonic it is simply being ignored!? All other properties are being saved OK. I am using SimpleRepository and RunMigrations, Subsonic v3.0.0.3.

public TimeSpan Time { get; set; }

Are TimeSpans not supported?

Answer 1

TimeSpan is not a valid 2005/2008 SQL data type.

Store it as a numeric based SQL data type. Convert your TimeSpan to an appropriate duration based on the accuracy you require:

// Define an interval of 1 day, 15+ hours.
TimeSpan interval = new TimeSpan(1, 15, 42, 45, 750); 
Console.WriteLine("Value of TimeSpan: {0}", interval);
Console.WriteLine("{0:N5} minutes, as follows:", interval.TotalMinutes);

Beware that there is a distinct difference between interval.Minutes and interval.TotalMinutes!

Thus:

// my duration
int duration = Time.TotalMinutes;
// now insert this into the database
