The specific syntax is as follows:<\/p>\n<pre class=\"post-pre\"><code>db.collection.updateOne(filter, update, options)\r\n<\/code><\/pre>\n<p>In this, collection represents the name of the set, filter represents the query criteria for matching documents, update represents the update operation to be performed, and options represent the update options.<\/p>\n<p>To add a field, you can use the $set operator in the update parameter and specify the field and its value to be added. For example, to add a field named age to all documents in the collection named users, you can use the following code:<\/p>\n<pre class=\"post-pre\"><code>db.users.update({}, {$set: {age: 25}}, {multi: true})\r\n<\/code><\/pre>\n<p>This will add a field named age with a value of 25 to all documents in the users collection. Note that by passing an empty object {} as the filter parameter, you can match all documents.<\/p>\n<p>If you want to add multiple fields, simply specify multiple fields and their values in the $set operator. For example, to add both age and gender fields at the same time, you can use the following code:<\/p>\n<pre class=\"post-pre\"><code>db.users.update({}, {$set: {age: 25, gender: 'male'}}, {multi: true})\r\n<\/code><\/pre>\n<p>This will add fields for age and gender to all documents, with their values set to 25 and &#8216;male&#8217; respectively.<\/p>\n<p>If you only want to add a field to the first matching document, you can use the updateOne method. For example, to add a field called age to the first document in a collection named users, you can use the following code:<\/p>\n<pre class=\"post-pre\"><code>db.users.updateOne({}, {$set: {age: 25}})\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"<p>In MongoDB, you can use the $set operator to add fields.
