-- Migration: Fix weekly_report_mv structure to include all projects via LEFT JOIN
|
|
-- This ensures the view structure matches the code in main.go
|
|
-- Date: 2024-12-29

|
|
-- Issue: Migration 005 created the view without LEFT JOIN to projects table,
|
|
-- which means projects without data were not included in the view.
|
|
-- This migration fixes the structure to match main.go implementation.
|
|
|
|
-- Drop existing materialized view
|
|
DROP MATERIALIZED VIEW IF EXISTS weekly_report_mv;

|
|

-- Recreate materialized view with correct structure (LEFT JOIN with projects)
|
|
-- This ensures all projects are included, even if they have no data for a given week
