Lets say I have a field in the DB with possible values 'Y', 'N', NULL. I want to represent it in my DTO with a boolean property ('N', NULL -> false, 'Y' - > true). Can I somehow plug into OrmLite to make the conversion myself (both directions, ofc) during the query/update/insert? Thanks
ORMLite uses simple POCOs so you can do something like this:
public class MyDto
{
// Values: Y, N, and NULL
public string SomeDbField { get; set; }
[Ignore]
public bool SomeDbFieldAccessor
{
get { return (SomeDbField != null && SomeDbField == "Y"); }
set { SomeDbField = value ? "Y" : "N"; }
}
}
The [Ignore]
attribute on the accessor field will tell ORMLite that the field should not be saved to / read from the database.
