mongo Shell脚本不会让我包含"use< database>" [英] mongo shell script won't let me include "use <database>"

问题描述

32位mongo 2.0.1

32-bit mongo 2.0.1 on a windows XP machine

//script filename: test.js  (one line shell script file to store a person)
db.cTest.save({Name: "Fred", Age:21});

通过输入以下2个shell命令对数据库dbTest运行:

run against database dbTest by entering the following 2 shell commands:

    > use dbTest
    switched to dbTest
    > load("test.js")

到目前为止，很好.

但是，如果我尝试在脚本中包含"use"语句，则会失败:

But if I try and include the "use" statement in the script it fails:

//script filename: test.js  (including "use" statement)
use dbTest;
db.cTest.save({Name: "Fred", Age:21});

失败，并显示以下错误消息:

fails with error msg as follows:

    > load("test.js")
    SyntaxError: missing ; before statement
    Mon Dec 19 11:56:31: Error: error loading js file temp.js (shell):1

在test.js中添加或删除分号似乎无关紧要.

Adding or removing semicolons to test.js doesn't seem to matter.

那么如何将"use"指令放入mongo shell脚本中?

So how do you put a "use" directive into a mongo shell script?

推荐答案

http://www.mongodb .org/display/DOCS/Scripting + the + shell

使用dbname
该命令在脚本模式下不起作用.相反，您将需要在连接中显式定义数据库(上例中为/dbname).

use dbname
This command does not work in scripted mode. Instead you will need to explicitly define the database in the connection (/dbname in the example above).

或者，您也可以在脚本中创建连接:

Alternately, you can also create a connection within the script:

db2 = connect("server:27017/otherdbname")

db2 = connect("server:27017/otherdbname")
