DIR查看 写道

  接下来是导入mongoimport

   

写道

D:\mongodb_64-2.6.4\bin>mongoimport --help

When importing JSON documents, each document must be a separate line of the inp

--quiet silence all non error diagnostic
messages
--version print the program's version and exit
-h [ --host ] arg mongo host to connect to ( <set

--jsonArray load a json array, not one item per
