mongodb - remove 需要在 src/mongo/shell/collection.js 查询

Question

运行 db.messages.remove() 时出现此错误。 “删除需要在 src/mongo/shell/collection.js 进行查询”。有解决此错误的建议吗？

Answer 1

正如消息所说，您需要提供一个查询，但它可以是一个空的(如果您想删除所有文档):

db.messages.remove({})

编辑:我想强调 Stennie 的评论:

Note: if you actually want to remove all documents in a collection it is faster to a do a collection.drop(). The remove() operation will delete documents individually & update indexes as the documents are deleted; a drop() will immediately delete all documents & indexes for the collection.
