Note that the ObjectIDs may be generated by the driver, or the application (or indeed manually) rather than by MongoDB itself, so unless you have full control over how they are generated, then any or all of the above may apply. That "inc" field is either an ever incrementing field (then you can reasonably expect the sort to be in the insert/create order) or a random value (then likely unique, but not ordered), assuming the spec is implemented correctly of course. prasad at 5:31 Add a comment 1 Answer Sorted by: 2 by default mongo appears to return documents in insertion order. The ObjectID now contains less context (you can't easily tell where it was generated and by what process) but I would guess that the information was not being used in any meaningful way and has been deprecated in favor of better randomisation of the ID. In general, the mongosh is the command line tool often preferred by developers and database administrators (this doesn't make difference in this specific use case). The last three bytes are still incremental, but initialised at a random value to start, again making collisions less likely. The ObjectID spec has evolved since this answer was written 8 years ago and the 5 bytes after the timestamp are now simply random, which will greatly decrease the likelihood of any collisions. This answer continues to be popular so it is worth updating a little. The most basic way to sort results it to provide a document specifying a single field indicating the column name with a value of 1. To specify ascending order for a field, set the field to 1 in the sort document. sort () method takes a document as an argument specifying the fields to sort as well as the sort direction. Enter the sort document into the Sort field. If these were created on the same machine (machine ID - the next 3 bytes), by the same process (PID - the next 2 bytes), then the only thing to differentiate them would be the "inc" field, the last 3 bytes at the end. MongoDB does not store documents in a collection in a particular order. The basic approach to sorting results in MongoDB is to append the. Here the positive one represents the ascending order, while the negative one represents the descending order. The sorting order in MongoDB is defined by either a one (1) or a minus (-1).
These building blocks are fields to be sorted and the sort order. Let us learn to find the document order by between dates with the help of an example.
And, we will use the sort () method to order by either in ascending or descending order. Using aggregation sort by date field in MongoDB Click on ADD STAGE and choose sort from the drop down list. After selecting SORT, choose the field that you’d like to sort on. In this tutorial, we’ll be focusing on sorting. You can choose from a number of options, such as FILTER, COLLATION and SORT. The correct syntax would look something like this: db.posts.find (.).sort date,pymongo. The following query returns all documents from the products collection where the price field exists.Since the ObjectID timestamp is only to the second, two (or more) ObjectIDs could easily be created with the same value for the timestamp (the first 4 bytes). The sort() method consists of two basic building blocks. MongoDB sort by date is used to sort the date field in ascending or descending order, we can sort the date by using the sort method in MongoDB. MongoDB order by date between When we want to find out the documents between dates then we will use the gt and lt operator. Open MongoDB Compass Open the database in which you create the collection and stored data Create collection into database using compass Click on Aggregation that is right side of documents.
