A consumer account may invoke an operation referencing a set of shared objects stored within a database of a provider account using an imported database that makes the set of shared objects available within the consumer account. A call context of the operation may be updated to cache the imported database, which references a share created from the provider account database, the share having grants to the set of shared objects. One or more database level objects may be discovered in a context of the share and each role granted to the share may be obtained based on the one or more database level objects. Whether any role granted to the share has access to any of the set of shared objects may be determined and the operation may be executed for each of the set of shared objects to which any role granted to the share has access.
