Mongodb mongo查询-语法错误：意外标记：

我收藏了一份文件

"_id" : ObjectId("5755b94abcfc6666d6f5fe56"),
"NAME" : John Smith,
"PHONE" : "800-555-1000",
"DOC" : {
    " TYPE" : "M",
    " DATE" : "01/28/2016",
    " AMOUNT" : 281593
},
"ADDRESS" : 123 Sesame Street

我试图通过传入键和值来查找此记录：

db.acris.find("DOC" : {" TYPE" : "MTGE"," DATE" : "01/28/2003"," AMOUNT" : 281593})

但是，我得到以下错误：

SyntaxError: Unexpected token :

如何修复此查询以使代码正常工作？

您在整个查找过程中缺少{}

db.collection.find（{“DOC”：…}）

更新： 只是为了完整。您还可以搜索整个元素。你不一定需要点符号

> db.test.insertOne({"NAME" : "John Smith",
... "PHONE" : "800-555-1000",
... "DOC" : {
...     " TYPE" : "M",
...     " DATE" : "01/28/2016",
...     " AMOUNT" : 281593
... },
... "ADDRESS" : "123 Sesame Street"})

> db.test.find({"DOC" : { " TYPE" : "M", " DATE" : "01/28/2016", " AMOUNT" : 281593 }})
{ "_id" : ObjectId("5759a933cdcc5a8d09a1aeb9"), "NAME" : "John Smith", "PHONE" : "800-555-1000", "DOC" : { " TYPE" : "M", " DATE" : "01/28/2016", " AMOUNT" : 281593 }, "ADDRESS" : "123 Sesame Street" }

你错过了{}整个发现，就像

db.collection.find（{“DOC”：…}）

更新： 只是为了完整。您还可以搜索整个元素。你不一定需要点符号

> db.test.insertOne({"NAME" : "John Smith",
... "PHONE" : "800-555-1000",
... "DOC" : {
...     " TYPE" : "M",
...     " DATE" : "01/28/2016",
...     " AMOUNT" : 281593
... },
... "ADDRESS" : "123 Sesame Street"})

> db.test.find({"DOC" : { " TYPE" : "M", " DATE" : "01/28/2016", " AMOUNT" : 281593 }})
{ "_id" : ObjectId("5759a933cdcc5a8d09a1aeb9"), "NAME" : "John Smith", "PHONE" : "800-555-1000", "DOC" : { " TYPE" : "M", " DATE" : "01/28/2016", " AMOUNT" : 281593 }, "ADDRESS" : "123 Sesame Street" }

语法错误已修复，如答案所示。但是，我认为您需要的问题是：

db.acris.find({"DOC.TYPE" : "M", "DOC.DATE" : "01/28/2003"," DOC.AMOUNT" : 281593})

请注意用于对子字段进行匹配的点符号。
