-- Fix: 发货单(biz_delivery_order) rfq_id 非空约束修复
|
|||
|
|
--
|
|||
|
|
-- 问题描述:
|
|||
|
|
-- client 类型发货单不关联 RFQ(询价单)，rfq_id 应为 NULL
|
|||
|
|
-- 若表存在 NOT NULL 约束，会导致 SQLIntegrityConstraintViolationException
|
|||
|
|
--
|
|||
|
|
-- 修复:
|
|||
|
|
-- 1) 确保 rfq_id 列允许 NULL
|
|||
|
|
-- 2) 补充缺失的 DDL（该表在项目中无建表脚本）
