-- 合同表结构更新脚本 (SQL Server)
|
||
-- 说明：此脚本用于将旧的合同表结构更新为新的结构
|
||
-- 请根据实际情况谨慎执行，建议先备份数据
|
||
-- ----------------------------
|
||
|
||
-- ----------------------------
|
||
-- 第一步：备份原有数据（可选，建议执行）
|
||
-- ----------------------------
|
||
-- select * into biz_contract_backup from biz_contract;
|
||
|
||
-- ----------------------------
|
||
-- 第二步：添加新字段（在删除旧字段之前）
|
||
-- SQL Server 不支持 if not exists，需要先检查列是否存在
|
||
-- ----------------------------

|

-- 如果需要从旧字段迁移数据到新字段，在这里写UPDATE语句
