-- 修复 Analytics RPC 函数权限问题
-- 解决无法访问 RPC 函数的问题
-- 1. 首先检查当前函数是否存在

FROM information_schema.routines
WHERE routine_schema = 'public'
AND routine_name IN ('get_teacher_analytics', 'get_top_performers', 'get_chart_data', 'get_recent_activities');
-- 2. 检查当前权限设置

grantor,
grantee,

is_grantable
FROM information_schema.routine_privileges
WHERE routine_schema = 'public'
AND routine_name IN ('get_teacher_analytics', 'get_top_performers', 'get_chart_data', 'get_recent_activities');
-- 3. 删除现有函数（如果存在权限问题）
DROP FUNCTION IF EXISTS public.get_teacher_analytics CASCADE;
DROP FUNCTION IF EXISTS public.get_top_performers CASCADE;

DROP FUNCTION IF EXISTS public.get_recent_activities CASCADE;
