多个DW进行update //菜鸟代码dw_1.Update()dw_2.Update()初级代码IF dw_1.Update() = 1 And dw_2.Update() = 1 THEN COMMIT;ELSE ROLLBACK;END IF中级代码IF dw_1.Update() = 1 THEN IF dw_2.Update() = 1 THEN COMMIT; ELSE
PB+MS SQL+触发器必须指出: 若触发器存在两笔以上的返回值,比方两条update 语句,被误判为数据有改变.存盘不成功. 提示: Row changed between retrieve and update. No changes made to database. 所以MS SQL 触发器必须统一处理为: 触发器開始加: if@@ROWCOUNT=0 Return --提高效能 setnocount on --不返回统计笔数,可降低网络频繁响应,提高效性能:避免误判为数据有改变(sy

13天的假期结束,赶紧回来充电了 本节目录 Web API简介 自我寄宿 IIS寄宿 调用Web API Web API原理 Web API简介 REST REST是“REpresentational State Transfer”的缩写,可以翻译成“表现状态转换”. REST是一种软件架构风格,与技术无关,但是大部分基于REST风格的Web服务都是基于HTTP的 (虽然WCF在3.5以后支持REST,但是WCF太庞大了,Web API更适合做REST架构) SOAP与REST SOAP Web
About Job Stores JobStores are responsible for keeping track of all the work data you give to the scheduler: jobs, triggers, calendars, and so forth. Selecting the appropriate JobStore for your Quartz scheduler instance is an important step. The choi
