Add documentation for DESCRIBE and DESC commands with syntax, examples, and output format explanation. Fixes #16518 ## Which issue does this PR close? - Closes #16518. ## Rationale for this change The `DESCRIBE` command was not documented in the user guide, making it difficult for users to discover and use this feature. ## What changes are included in this PR? Adds documentation to `docs/source/user-guide/sql/ddl.md` including: - Syntax for both `DESCRIBE` and `DESC` aliases - Output format explanation (column_name, data_type, is_nullable) - Three examples: basic usage, DESC alias, and external tables - Compatibility note for all table types ## Are these changes tested? The `DESCRIBE` command functionality is already tested in `datafusion/sqllogictest/test_files/describe.slt` and `information_schema.slt`. This PR only adds documentation. ## Are there any user-facing changes? Yes - users can now find `DESCRIBE` command documentation in the official user guide with clear usage examples and expected output format. -- This is an automated message from the Apache Git Service.
