In-database application package and application
An in-database application package and application instance for a data platform. The data platform creates an application instance of an application package having a versioned schema, creates one or more system roles for the application instance, creates a user role and an administrator role for the application instance, creates one or more objects of the application instance based on a versioned schema, and grants one or more use privileges to the one or more roles. Application instances of the application package are upgraded or patched on the data platform based on application package versions. To ensure a proper upgrade or patch, the data platform tracks versions of executing objects of application instances in a call context.
1. A computer-implemented method of a data platform, the method comprising:
creating, by one or more processors, an application instance of an application package having a versioned schema;

granting, by the one or more processors, one or more usages to the one or more user roles based on the versioned schema, the one or more usages comprising use privileges to access objects of the application package; and
determining, by the one or more processors executing a first procedure, a version context of a second procedure based on a versioned schema, wherein the version context of the second procedure is determined by rules comprising;
in response to determining the second procedure is associated with a call context, use a version of a call context of the first procedure and the second procedure;
in response to determining there is a global version set on a parent database of the first procedure and the second procedure, use the global version; and
in response to determining the second procedure not associated with the call context and no global version set on the parent database, use an active version associated with the versioned schema.

creating one or more objects of the application instance based on the versioned schema;
granting one or more usages to the one or more user roles based on the versioned schema, the one or more usages comprising use privileges to access objects of the application package; and
determining, by a first procedure, a version context of a second procedure based on a versioned schema, wherein the version context of the second procedure is determined by rules comprising;
in response to determining the second procedure is associated with a call context, use a version of a call context of the first procedure and the second procedure;
in response to determining there is a global version set on a parent database of the first procedure and the second procedure, use the global version; and
in response to determining the second procedure not associated with the call context and no global version set on the parent database, use an active version associated with the versioned schema.
