-- author:GHT---date:20260616--for: 【MES上辅机】生产环境 SQL Server 中间库连接池校验 DUAL 报错修复 ---
原因：application-prod.yml 全局 druid.validationQuery 为 SELECT 1 FROM DUAL，动态创建的 sqlserver_mcs 数据源继承该配置后在 SQL Server 上报「对象名 DUAL 无效」。
修改：prod 全局改为 SELECT 1；McsDataSourceManager 创建/恢复 SQL Server 数据源时显式设置 validationQuery=SELECT 1。
