I would like to know if there is Standard SObject for Changeset or Package? I noticed that 033 is prefix for Package and 0A2 is key prefix for Changeset. However, neither of there objects are not exposed through API or SOQL. I tried this code to run but it returns nothing for 0A2 or 033.

Is there any reason why SFDC doesn't want to make these objects public for SOQL?

Update: also I am interested in 034 which looks like prefix for package component.

Using Adrian Larson's code, it gives PackageMember

system.debug(LoggingLevel.ERROR, Id.valueOf('03423000000MFWY').getSObjectType());
  • The key prefix 0A2 corresponds to the DevelopmentPackageVersion object.
  • The key prefix 033 corresponds to the AllPackage object.

A more comprehensive (and significantly faster, I imagine) methodology for taking a key prefix or Id is this fairly simple approach:


Given the prefix only, you can right-pad with zeroes until you get to 15 digits and you will get the same result as if you copy-pasted the whole id.

  • you are totally right , I am fool that I didn't find this myself – Patlatus Sep 7 '16 at 11:14
  • Eh that's being too hard on yourself. As for why these objects are not publicly documented or available for query, I'm not sure, but I'm hardly surprised, either. – Adrian Larson Sep 7 '16 at 11:16
  • Actually knowing the sobject name doesn't help me much, still when I try to make SOQL query (either usual or "Use Tooling API"), it says that "sObject type 'DevelopmentPackageVersion' is not supported." or "sObject type 'AllPackage' is not supported." – Patlatus Sep 7 '16 at 11:30
  • Yeah, I do not believe you actually can query for them, but that's a slightly different question in and of itself, apart from identifying the objects represented by those Ids. I did a bit of searching but didn't find anything just yet. – Adrian Larson Sep 7 '16 at 11:37

    Yeah, I imagine so. Might take a few years to get any traction. :( – Adrian Larson Sep 7 '16 at 11:49
