NotMapped attribute for PetaPoco or Ignore Column while Insert/Update in Petapoco

NotMapped Property for PetaPoco or Ignore Column while Insert/Update in Petapoco

[NotMapped]   ==>  [ResultColumn]

[NotMapped] equivalent of entity framework in Petapoco is [ResultColumn]

For more information

Example:  If you have contact form model where you want user to enter captcha, but you don't want this captcha to be store in db, so In order to ignore captcha column while inserting values in database you can mark the column as [NotMapped] in entity framework and if you are using Petapoco you can use attribute [ResultColumn]

[TableName("contact")]
[ExplicitColumns]
public class contact
{
    [Column] 
    public string FullName { get; set; }
    
    [Column] 
    public string Feedback { get; set; }
    
    [ResultColumn] 
    public string Captcha { get; set; }
}
