    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a providing stored procedures in a network-based database system. A database system executes a stored procedure within a sandbox process. The sandbox process separates the stored procedure from the other services and processes of the database system and may also limit the resources (e.g., storage, memory, etc.) and functionality available to the stored procedure. Stored procedures are commonly designed to execute database queries that are processed by other components of the database system. To provide for secure communication between the stored procedure and the other components of the database system, the sandbox process is loaded with java database connectivity (JDBC) libraries (e.g., JDBC instance) that is modified to limit the communication abilities of the stored procedure.

    Abstract: A database system configured to manage and execute stored procedures within a secure sandbox process. The system receives a response to a database query and, through an Application Programming Interface (API) executing within the sandbox process, converts the response into a remote procedure call. The sandbox process is modified to restrict communication with external networks while enabling communication with a designated execution node, which facilitates interaction between the stored procedure and database system components. The stored procedure, executing within the confines of the sandbox process, directs the API to communicate with the execution node. The execution node, in turn, submits the database query to the database system component.
