+-- PERIOD GENERATOR - Phase 7 Long Format Output
+-- ==============================================================================
+-- This file contains the reusable recursive CTE pattern for generating
+-- dynamic rolling periods from June 2025 to the current month.
+--
+-- Requirements:
+-- - Earliest period: ends 2025-06-30 (hardcoded)
+-- - Latest period: ends at last day of current month (dynamic)
+-- - One period per month from June 2025 to current month
+-- - 12-month lookback for M1, M2, M3, M5, M6, M7, M8
+-- - 6-month lookback for M4 (Female UTI)
+--
+-- Example output (run 2026-01-29):
+--   8 periods: Jun 25, Jul 25, Aug 25, Sep 25, Oct 25, Nov 25, Dec 25, Jan 26

+-- 8 periods total (June 2025 through January 2026)
+-- ==============================================================================
+
+-- ==============================================================================
+-- USAGE NOTES
+-- ==============================================================================
+-- 1. For 12-month measures (M1, M2, M3, M5, M6, M7, M8):
+--    Filter data WHERE date_column BETWEEN "PeriodStartDate_12m" AND "PeriodEndDate"
+--
+-- 2. For 6-month measure (M4):
+--    Filter data WHERE date_column BETWEEN "PeriodStartDate_6m" AND "PeriodEndDate"
+--
+-- 3. The recursive CTE is dynamic:
+--    - Running in January 2026 → 8 periods
+--    - Running in February 2026 → 9 periods
+--    - Running in June 2026 → 13 periods
+--
+-- 4. This pattern should be included at the START of each measure query
+--    before the main data CTEs.

+-- ROLLING PERIODS TEMPLATE - Phase 7 Long Format Output
+-- ==============================================================================
+-- This file documents the reusable CTE patterns for generating rolling time
+-- periods for both dispensing and prescribing data sources.
+--
+-- Key considerations:
+-- - Dispensing data: 2018-04 to 2025-07 (88 months) - full historical coverage
+-- - Prescribing data: 2024-01 to 2026-01 (25 months) - LIMITED HISTORY
+--   (prescribing period 2 will have partial/no data)
+--
+-- IMPORTANT: Each data source has its own MAX date, so periods must be
+-- calculated separately within each UNION ALL branch.

+-- PATTERN 1: 12-MONTH ROLLING PERIODS (for M1, M2, M3, M5, M6, M7, M8)
+-- ==============================================================================
+-- Generates 3 rolling periods covering approximately 3 years:

+-- UNIFIED SQL TEMPLATE - Phase 7 Long Format Output
+-- ==============================================================================
+-- This template shows the complete pattern for converting measures to long format
+-- with both dispensing and prescribing data sources and rolling time periods.
+--
+-- Output columns (7 standard columns):
+--   OrganisationName  - GP Practice name
+--   PeriodStartDate   - Start of the time window (DATE type)
+--   PeriodEndDate     - End of the time window (DATE type)
+--   DataSource        - 'Dispensing' or 'Prescribing'
+--   Measure           - Measure identifier (e.g., 'M2')
+--   Indicator         - Metric name (e.g., 'TotalPrescriptions')
+--   Value             - The metric value (FLOAT type)
+--
+-- Key patterns:
+-- 1. Recursive CTE generates all periods from June 2025 to current month
+-- 2. Cross join practices with periods for all combinations
+-- 3. Left join dispensing data filtered by date range per period
