+-- 迁移：为 dws_member_winback_index 和 dws_member_newconv_index 添加 visits_30d 字段
+-- Fix-3：recall 维度需要 30 天到店次数，原先用 visits_14d 近似
+-- 日期：2026-04-07
+-- 重要：加列后必须重建所有引用这两张表的视图，否则视图看不到新列
+
+-- 1. 加列
+ALTER TABLE dws.dws_member_winback_index
+    ADD COLUMN IF NOT EXISTS visits_30d integer DEFAULT 0 NOT NULL;

+ALTER TABLE dws.dws_member_newconv_index
