Update Documents

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:

The following example uses the mongoc_collection_update_one function on the inventory collection to update the first document where item equals "paper":

The following example uses the IMongoCollection.UpdateOne() method on the inventory collection to update the first document where item equals "paper":

The following example uses the Collection.UpdateOne method on the inventory collection to update the first document where item equals "paper":

The following example uses the com.mongodb.reactivestreams.client.MongoCollection.updateOne on the inventory collection to update the first document where item equals "paper":

The following example uses the com.mongodb.client.MongoCollection.updateOne method on the inventory collection to update the first document where item equals "paper":

The following example uses the MongoCollection.updateOne() method on the inventory collection to update the first document where item equals "paper":

The following example uses the Collection.updateOne() method on the inventory collection to update the first document where item equals "paper":

The following example uses the updateOne() method on the inventory collection to update the first document where item equals "paper":

The following example uses the update_one method on the inventory collection to update the first document where item equals "paper":

The following example uses the update_one() method on the inventory collection to update the first document where item equals "paper":

The following example uses the updateOne() method on the inventory collection to update the first document where item equals "paper":

db.inventory.updateOne(
   { item: "paper" },
   {
     $set: { "size.uom": "cm", status: "P" },
     $currentDate: { lastModified: true }
   }
)

The update operation:

• uses the $set operator to update the value of the size.uom field to "cm" and the value of the status field to "P",

• uses the $currentDate operator to update the value of the lastModified field to the current date. If lastModified field does not exist, $currentDate will create the field. See $currentDate for details.

Modify the target document as follows:

• Change the status field from D to P.

• Change the size.uom field from in to cm.

• Add a new field called lastModified whose value will be today's date.

1. Click the Table button in the top navigation to access the Table View:

   

2. Use the Compass query bar to locate the target document.

   Copy the following filter document into the query bar and click Find:

   { item: "paper" }
   

3. Hover over the status field and click the pencil icon which appears on the right side of the document to enter edit mode:

   

4. Change the value of the field to "P".

5. Click the Update button below the field to save your changes.

6. Hover over the size field 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 the size object:

   

7. Using the same process outlined in steps 3-5 for editing the status field, change the value of the size.uom field to "cm".

8. Click the left-most tab above the table labelled inventory to return to the original table view, which displays the top-level document:

   

9. Hover over the status field and click the pencil icon which appears on the right side of the document to re-enter edit mode.

10. Click inside of the status field 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:

    

11. Add a new field called lastModified with a value of today's date. Set the field type to Date:

    

12. Click the Update button below the field to save your changes.

    Note

    Because MongoDB Compass does not support $currentDate or any other Field Update Operators, you must manually enter the date value in Compass.

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. The replacement document cannot 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":
