#Object Data Model

Hi Developers!

Sometimes we need to deal with classes/tables where the primary key and the IdKey are something that is maintained by yourself.

What is the proper way to generate a new ID in case where ID is a %BigInt?

Property id As %Library.BigInt

Are there any system methods to provide it?

There is data already imported via SQL, so there is no last ID stored in ^myclassD, so I cannot do $I(^myclassD).

Thinking of:

set newid=$O(^myclassD(""),-1),newid=$I(newid)

What do you think?

Hi Developers!

Consider I have a persistent class derived from %Persistent and I want it to be derived from %JSON.Adaptor to enjoy all the JSON features.

Can I do it programmatically? 

So, it'd be wonderful to have a method in some util class that makes it happen? Something like:

Do ClassUtil.AddAncestor("MyPackage.MyPersistentClass","%JSON.Adaptor")

Any ideas?

Hello Community

The InitialExpression keyword values does not to set default values for properties in classes that extend %CSP.Page, unlike in other class types such as %Persistent or %RegisteredObject, where it works as expected during object instantiation (typically via %New()).

1. Is %CSP.Page instantiated using %New() under the hood, or does it use a different initialization mechanism?
2. Are there specific limitations or behaviors in CSP pages that prevent InitialExpression from working as expected?

Thank you!

Is there a way to Remove specific all Addresses from a Provider.Individual.Address before reinserting the Addresses from an HL7 message in Provider Directory?

Most fields we can call %clearFields() however since Addresses come from multiple locations we need to isolate and treat Addresses from this HL7 source as a snapshot.

Thanks

Hello Community,

When retrieving strings from the DAO, if the string exceeds the capacity of an ObjectScript string variable, it returns <MAXSTRING>. To prevent this, use dao.%Get(key, default, "stream") to retrieve the value as a stream (%Stream.DynamicBinary). However, Why can't we use other stream objects such as %Stream.TmpCharacter instead of %Stream.DynamicBinary/%Stream.DynamicCharacter (I understand It is not possible to create a direct object instance for %Stream.Dynamic* classes) .
