How to get values from a serialobject class

#Beginner #Object Data Model #ObjectScript #SQL #Caché #Ensemble

Hi,

I

want to get the values from a serial property because my code depends upon the class serial class.

For example

Serial class

Class Data.Serial Extends %SerialObject

{

Property FirstName as %String;

Property LastName as %String;

}

Persistent class

Class Data.Persistent Extends %Persistent

{

Property MPID as %Integer;

Property Name as Name.Serial;

}

Now i need save MPID and Name(Serial class property into SQL Table ) so i am trying the below class

Class Data.TestUtil Extends  %RegisteredObject

{

Method Savedata(MPID,FirstName,LastName)

{

Set tSC=0

Set Obj=##Class(Data.Persistent).%New()

Set Obj.MPID=MPID

Set Obj.FirstName=FirstName
Set Obj.LastName=LastName

Set tSC=Obj.%Save()

Quit tSC

}

}

But data is not getting saved into SQL data and throwing an error, How to save serial class Property into the SQL table?

Thanks,

Smythee

If your serial class is named Data.Serial (as in your example code) then you should use the same name for the serial property too

Class Data.Persistent Extends %Persistent
{
Property MPID as %Integer;
Property Name as Data.Serial;   <--- !!!!!
}

The correct way to set the values

Set Obj=##Class(Data.Persistent).%New()
Set Obj.MPID=MPID
Set Obj.Name.FirstName=FirstName   ; <----
Set Obj.Name.LastName=LastName     ; <----
Set tSC=Obj.%Save()
