To update a document, MongoDB provides
update operators, such
as $set, to modify field values.
To use the update operators, pass to the update methods an update document of the form:
Some update operators, such as $set, will create the field if
the field does not exist. See the individual
update operator reference for
details.
To update a document in Compass, hover over the target document and click the pencil icon:
After clicking the pencil icon, the document enters edit mode:
You can now change the this document by clicking the item you wish to change and modifying the value.
For detailed instructions on updating documents in Compass, refer to the Compass documentation or follow the example below.
Once you are satisfied with your changes, click Update to save the updated document.
Click Cancel to revert any modifications made to the document and exit edit mode.

The following example uses the
db.collection.updateOne() method on the
inventory collection to update the first document where
item equals "paper":
The following example demonstrates using MongoDB Compass to modify
a single document where item: paper in the inventory
collection:
Note
This example uses the Compass Table View to modify the document. The editing process using the Compass List View follows a very similar approach.
For more information on the differences between Table View and List View in Compass, refer to the Compass documentation.
The following example uses the
update_one() method on
the inventory collection to update the first document

The update operation:
- uses the
$setoperator to update the value of thesize.uomfield to"cm"and the value of thestatusfield to"P", - uses the
$currentDateoperator to update the value of thelastModifiedfield to the current date. IflastModifiedfield does not exist,$currentDatewill create the field. See$currentDatefor details.
Modify the target document as follows:
- Change the
statusfield fromDtoP. - Change the
size.uomfield fromintocm. - Add a new field called
lastModifiedwhose value will be today’s date.
Click the Table button in the top navigation to access the Table View:
Use the Compass query bar to locate the target document.
Copy the following filter document into the query bar and click Find:
Hover over the
statusfield and click the pencil icon which appears on the right side of the document to enter edit mode:
Change the value of the field to
"P".Click the Update button below the field to save your changes.
Hover over the
sizefield and click the outward-pointing arrows which appear on the right side of the field. This opens a new tab which displays the fields within thesizeobject:
Using the same process outlined in steps 3-5 for editing the
statusfield, change the value of thesize.uomfield to"cm".Click the left-most tab above the table labelled
inventoryto return to the original table view, which displays the top-level document:
Hover over the
statusfield and click the pencil icon which appears on the right side of the document to re-enter edit mode.Click inside of the
statusfield and click the plus button icon which appears in the edit menu.Click the Add Field After status button which appears below the plus button:
Add a new field called
lastModifiedwith a value of today’s date. Set the field type toDate:
Click the Update button below the field to save your changes.
Note
Because MongoDB Compass does not support
$currentDateor any other Field Update Operators, you must manually enter the date value in Compass.

Replace a Document
To replace the entire content of a document except for the _id
field, pass an entirely new document as the second argument to
db.collection.replaceOne().
When replacing a document, the replacement document must consist of only field/value pairs; i.e. do not include update operators expressions.
The replacement document can have different fields from the original
document. In the replacement document, you can omit the _id field
since the _id field is immutable; however, if you do include the
_id field, it must have the same value as the current value.
The following example replaces the first document from the
inventory collection where item: "paper":

Behavior¶
Atomicity¶
All write operations in MongoDB are atomic on the level of a single document. For more information on MongoDB and atomicity, see Atomicity and Transactions.
_id Field¶
Once set, you cannot update the value of the _id field nor can you
replace an existing document with a replacement document that has a
different _id field value.
Document Size¶
For the deprecated MMAPv1, when performing update operations that increase the document size beyond the allocated space for that document, the update operation relocates the document on disk.
Field Order¶
MongoDB preserves the order of the document fields following write operations except for the following cases:
- The
_idfield is always the first field in the document. - Updates that include
renamingof field names may result in the reordering of fields in the document.
Changed in version 2.6: Starting in version 2.6, MongoDB actively attempts to preserve the field order in a document. Before version 2.6, MongoDB did not actively preserve the order of the fields in a document.
