mysql - Sql query to combine 2 diff. column output based on conditions -

-

I want to add 2 columns to the new column based on the circumstances. Please check the query below. What I tried was 

  Select 'Contacts'. ContactSarpsi``, 'Contacts'. 'Pars', 'Contacts'. Contact 'BDRPlus' with 'Contact'. WHERE (`` ContactPers``` parse ID` = 55) or (`ContactPers`.contactID = 55)) and` ContactPers`.`etat` = 1

Output: 

  contact_persID persID contactID 18 90 55 19 55 56 20 55 61 23 55 67

The desired output is something (55 not in the new column, as it does Based on the circumstance, you want to add the press and contact ID.) 

  contact_persID persID contactID newColumn 18 90 55 90 19 55 56 56 20 55 61 61 23 55 67 67  < / Pre> 
 - Thank you

I'm not sure about MySQL. Here's how I should do it in SQL: 

  Select 'Contacts' ContactSarpsi``, 'Contacts'. 'Paper', 'Contacts' 'Contact', 'Agent' Preceded 'When 55' 'Contacts' Contact 'ALSE' contacts. ' 'Bidrplus' with new column as 'FID'. Contact 'A' contact providers where in 55 (`contacts'. 'Paper', 'contacts' .contactID) and' contacts' .````` =

-
I know that a XmlSerializer throws an exception if the type passed does not match the type Since then the serializer was created My question is: Is it possible to serial the base type without knowing the derivative type? Consider the following scenario: The following classes are in a top-level domain and there is no dependency : Public Class Serializer {Private Static String Serialize (base basedata) {var serializer = New XML serializer (typefile); Var sb = new stringbilder (); (Var author = XmlWriter.Create (sb)) using {serializer.Serialize (author, bassadata); } Return sb.ToString (); } Private static string Deserialize (...) {...}} Public class base {public string name {get; Set; }} The following derivative classes have additional dependencies on things like UI components, structure, etc. (and more on this later): [Export (Typ (IMyComponent)] Public category was created: Base, IMyComponent, INotifyPropertyChanged {public new string name {get {return base.Name; ...
