REGAL+: Reverse Engineering SPJA Queries
Summary: REGAL+ extends reverse engineering to SPJA queries over arbitrary schemas, enabling reconstruction of the originating SQL from a data report. Without prior schema knowledge or SQL expertise, users upload a spreadsheet and REGAL+ outputs candidate SPJA queries that reproduce the report, highlighting broad applicability.
