-- ============================================================================
|
|
-- Migration: Unify common functions in public schema
|
|
-- Date: 2026-02-03
|
|
-- Task: ST-2.3
|
|
-- Issue: DUP-003 - update_updated_at() duplicated across schemas
|
|
-- ============================================================================
|
|
-- Purpose: Create a unified update_updated_at() function in the public schema
|
|
-- to replace duplicated functions in auth, education, financial, and
|
|
-- feature_flags schemas.
|
|
-- ============================================================================
|
|
|
|
-- ============================================================================
|
|
-- STEP 1: Create unified function in public schema
|
|
-- ============================================================================
|
|
|
|
CREATE OR REPLACE FUNCTION public.update_updated_at()
|
|
RETURNS TRIGGER AS $$
|
|
BEGIN
|
|
NEW.updated_at = NOW();
|
|
RETURN NEW;
|
|
END;
|
|
$$ LANGUAGE plpgsql;
|
|
|
|
COMMENT ON FUNCTION public.update_updated_at() IS
|
|
'Unified trigger function for updated_at. Replaces schema-specific versions.
|
|
Issue: DUP-003 | Task: ST-2.3';
|
|
|
|
-- ============================================================================
|
|
-- STEP 2: Document deprecated functions
|
|
-- ============================================================================
|
|
-- The following schema-specific functions are now deprecated:
|
|
--
|
|
-- | Schema | Function Name | File Location |
|
|
-- |---------------|----------------------------|-----------------------------------------|
|
|
-- | auth | update_updated_at() | schemas/auth/functions/01-update_updated_at.sql |
|
|
-- | education | update_updated_at_column() | schemas/education/functions/01-update_updated_at.sql |
|
|
-- | financial | update_timestamp() | schemas/financial/functions/03-triggers.sql |
|
|
-- | feature_flags | update_timestamp() | schemas/feature_flags/tables/01-flags.sql |
|
|
--
|
|
-- These functions are NOT dropped in this migration to avoid breaking
|
|
-- existing triggers. Future migrations should:
|
|
-- 1. Update triggers to use public.update_updated_at()
|
|
-- 2. Drop the deprecated schema-specific functions
|
|
-- ============================================================================
|
|
|
|
-- ============================================================================
|
|
-- STEP 3: Example trigger update (DO NOT EXECUTE - FOR REFERENCE ONLY)
|
|
-- ============================================================================
|
|
-- To migrate a trigger from schema-specific to public function:
|
|
--
|
|
-- -- For auth.users table:
|
|
-- DROP TRIGGER IF EXISTS trigger_update_users_updated_at ON auth.users;
|
|
-- CREATE TRIGGER trigger_update_users_updated_at
|
|
-- BEFORE UPDATE ON auth.users
|
|
-- FOR EACH ROW
|
|
-- EXECUTE FUNCTION public.update_updated_at();
|
|
--
|
|
-- -- For education.courses table:
|
|
-- DROP TRIGGER IF EXISTS update_courses_updated_at ON education.courses;
|
|
-- CREATE TRIGGER update_courses_updated_at
|
|
-- BEFORE UPDATE ON education.courses
|
|
-- FOR EACH ROW
|
|
-- EXECUTE FUNCTION public.update_updated_at();
|
|
--
|
|
-- -- For financial.wallets table:
|
|
-- DROP TRIGGER IF EXISTS trigger_wallets_updated_at ON financial.wallets;
|
|
-- CREATE TRIGGER trigger_wallets_updated_at
|
|
-- BEFORE UPDATE ON financial.wallets
|
|
-- FOR EACH ROW
|
|
-- EXECUTE FUNCTION public.update_updated_at();
|
|
-- ============================================================================
|
|
|
|
-- ============================================================================
|
|
-- VERIFICATION QUERY
|
|
-- ============================================================================
|
|
-- Run this query to verify the function was created:
|
|
--
|
|
-- SELECT
|
|
-- n.nspname AS schema,
|
|
-- p.proname AS function_name,
|
|
-- d.description AS comment
|
|
-- FROM pg_proc p
|
|
-- JOIN pg_namespace n ON p.pronamespace = n.oid
|
|
-- LEFT JOIN pg_description d ON d.objoid = p.oid
|
|
-- WHERE p.proname = 'update_updated_at'
|
|
-- ORDER BY n.nspname;
|
|
-- ============================================================================
|
|
|
|
-- ============================================================================
|
|
-- ROLLBACK (if needed)
|
|
-- ============================================================================
|
|
-- DROP FUNCTION IF EXISTS public.update_updated_at();
