The cloud-dwelling community here is simple to organize the common method, convenient for everyone to use. It's all through VBScript code.
The way to hide the cmd window while running a bat can edit a VBS script in which the batch program runs with a hidden window.
Copy Code code as follows:
Set ws = CreateObject ("Wscript.Shell")
Ws.run "cmd/c Batch program name", Vbhide
Copy the code above to Notepad, save it as "Runbat.vbs

注意:已经告知我们mongo不支持事务,在开发项目应用时,想要保证数据的完整性请考虑关系型数据库(经典例子银行转账)。mongo提供了许多原子操作,比如文档的保存,修改,删除等,都是原子操作。所谓原子操作就是要么这个文档保存到mongodb,要么没有保存到mongodb,不会出现查询到的文档不完整的情况。
