# Phase 22 Plan 01: README DDL Syntax Update Summary

**README rewritten with native CREATE SEMANTIC VIEW DDL as primary interface, all 7 DDL verbs documented, lifecycle worked example added**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-09T13:51:30Z
- **Completed:** 2026-03-09T13:53:59Z
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments
- Replaced function-based `create_semantic_view()` examples with native `CREATE SEMANTIC VIEW` DDL syntax
- Added DDL reference section covering all 7 verbs (CREATE, CREATE OR REPLACE, CREATE IF NOT EXISTS, DROP, DROP IF EXISTS, DESCRIBE, SHOW)
- Added lifecycle worked example demonstrating full create-query-describe-show-drop workflow
- Updated version from v0.4.0 to v0.5.0
- Added Function syntax section noting backward compatibility of function-based DDL
- Total README length: 187 lines (under 200 target)

## Task Commits

Each task was committed atomically:

1. **Task 1: Rewrite README with native DDL syntax** - `d4e801b` (docs)
2. **Task 2: Validate README accuracy and test suite** - no commit (validation-only, no fixes needed)

## Files Created/Modified
- `README.md` - Rewritten with native DDL syntax, DDL reference, lifecycle example, function syntax note

## Decisions Made
- DDL reference condensed to a single code block with inline comments rather than separate heading+block per verb (keeps README compact at 187 lines)
- Function-based syntax retained as a brief alternative section rather than being removed entirely

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Phase 22 (documentation) complete -- README fully updated for v0.5.0
- Ready for community extension registry submission or next milestone

## Self-Check: PASSED

- README.md: FOUND
- 22-01-SUMMARY.md: FOUND
- Commit d4e801b: FOUND
