ServiceStack ORMLite SqlList issue with DateTime

Question

I am in the process of upgrading from v4.0.36 to v4.0.46 and I'm getting issues where the SQL that is generated through this API doesn't convert the DateTime values correctly:

public static List<T> SqlList<T> (this IDbConnection dbConn, string sql, object anonType = null);

The DateTime would be an attribute as part of object passed through to the method.

When on v4.0.36 the DateTime value would result in the string "yyyy-MM-dd HH:mm:ss"

However after upgrading to v4.0.46 the DateTime value is now "dd/MM/yyyy HH:mm:ss AM"

and because of this queries that rely on a date are now not returning any records because MySQL doesn't recognise this format.

Is there a config I'm missing? Or any pointers on what changes I need to make to get the same behaviour as 4.0.36?

Answer 1

This should now be resolved from this commit, available from v4.0.47 that's now available on MyGet which supports each of the call styles below:

class DateTest
{
    public DateTime Test { get; set; }
    public DateTime? TestNullable { get; set; }
}

using (var db = OpenDbConnection())
{
    db.DropAndCreateTable<DateTest>();

    var dateTime = new DateTime(2001, 1, 1, 1, 1, 1);
    db.Insert(new DateTest{ Test = dateTime, TestNullable = dateTime });

    var row = db.SqlList<DateTest>(
        "SELECT * FROM DateTest WHERE Test = @dateTime"), new { dateTime });

    row = db.SqlList<DateTest>(
        "SELECT * FROM DateTest WHERE TestNullable = @dateTime"), new { dateTime });

    DateTime? nullDate = dateTime;
    row = db.SqlList<DateTest>(
        "SELECT * FROM DateTest WHERE TestNullable = @nullDate"), new { nullDate });
}
