Julian Hyde created CALCITE-5292: ------------------------------------ Summary: Add a policy that can prevent SQL statements from running if they contain certain functions / operators Key: CALCITE-5292 URL: https://issues.apache.org/jira/browse/CALCITE-5292 Project: Calcite Issue Type: Bug Reporter: Julian Hyde
Add a policy that can prevent SQL statements from running if they contain certain operators, including built-in functions and operators. One use of this policy would be to disable functions that contain serious bugs. For example, we could have prevented use of {{EXTRACTVALUE}} as a workaround to CALCITE-5263. Calcite's predecessor [LucidDB|https://github.com/LucidDB/luciddb] had policy-driven access to tables, but this code was never fully enabled in Calcite. Ironically, the last remaining code was deprecated in CALCITE-4953. We should consider reviving the policy and making it handle tables and functions/operators. -- This message was sent by Atlassian Jira (v8.20.10#820010)
