-- 1) 项目：结束日期索引（逾期判定 + 按结束日期排序）
ALTER TABLE `yz_backend_crm_project`
ADD INDEX `idx_end_date` (`end_date`);
-- 可重复执行：索引不存在时才执行 ALTER，已存在自动跳过（不再报 1061 Duplicate key）。
SET @tbl := (SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = DATABASE() AND TABLE_NAME = 'yz_backend_crm_project');
SET @idx := (SELECT COUNT(*) FROM INFORMATION_SCHEMA.STATISTICS WHERE TABLE_SCHEMA = DATABASE() AND TABLE_NAME = 'yz_backend_crm_project' AND INDEX_NAME = 'idx_end_date');
SET @ddl := IF(@tbl > 0 AND @idx = 0, 'ALTER TABLE `yz_backend_crm_project` ADD INDEX `idx_end_date` (`end_date`)', 'DO 0');

-- 2) 合同：到期日期索引（逾期判定 + 按到期日期排序）
ALTER TABLE `yz_backend_crm_contract`
ADD INDEX `idx_expire_date` (`expire_date`);
SET @tbl := (SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = DATABASE() AND TABLE_NAME = 'yz_backend_crm_contract');

SET @ddl := IF(@tbl > 0 AND @idx = 0, 'ALTER TABLE `yz_backend_crm_contract` ADD INDEX `idx_expire_date` (`expire_date`)', 'DO 0');
PREPARE stmt FROM @ddl; EXECUTE stmt; DEALLOCATE PREPARE stmt;
-- 3) 回款明细逾期：plan_date 内嵌于 items(JSON)，无法建单列索引。
-- 如需按「逾期回款明细」做服务端统计，建议将回款明细拆为独立子表
