Hi @JackieTien97, I have implemented the initial framework for DESCRIBE QUERY in the Table Model. This PR includes: Grammar Support: Added DESCRIBE QUERY syntax in RelationalSql.g4. AST Node: Created the DescribeQuery class to represent the statement. Analyzer Integration: Updated StatementAnalyzer to handle DescribeQuery. It now correctly extracts the output symbols and types from the underlying query. Validation: Verified the logic with debug logs; it correctly identifies columns and their types for relational queries. The local build is successful (BUILD SUCCESS). Next Steps: 1. Implement DescribeOperator to return the metadata in a tabular format. 2. Integrate the operator into the LogicalPlanner. Please let me know your initial thoughts on this approach. -- This is an automated message from the Apache Git Service.
