Multiple environments and functions in a distributed database

A system comprising:

• one or more computer processors;
• and
• one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the system to perform operations comprising:
• storing a user application on a distributed database system;
• identifying a plurality of package dependencies of the user application, the plurality of package dependencies comprising a first package dependency and a second package dependency;
• generating a first execution environment that comprises the first package dependency;
• generating a second execution environment that comprises the second package dependency;
• receiving a database statement that includes a first portion using the first package dependency and a second portion using the second package dependency;
• and
• based on receiving the database statement, generating results data using the first execution environment and the second execution environment.
