# object\_merge

**Syntax**

```programlisting
object_merge(<obj1>, <obj2>, <obj3>, ...)
```

**Description**

The `object_merge()` function returns a new object, which is created from a merge of a number of objects. When there is a key name that is duplicated in any of the objects, the value in the new object is determined by the latter argument.

**Example**

Two objects are created and merged, where some key names are duplicated, including `name`, `last_name`, and `age`. Since the `name` value is the same for both objects, the same name is used in the new object. Yet, the `last_name` and `age` key values differ, so the values from the second object are used in the new object.

```programlisting
dataset = xdr_data
| alter
  obj1 = object_create("name", "jane", "last_name", "doe", "age", 33),
  obj2 = object_create("name", "jane", "last_name", "simon", "age", 34, "city", "new-york")
| alter result = object_merge(obj1, obj2)
| fields result
```

The function returns the following new object in the **RESULT** column of the results table:

```programlisting
{"name": "jane", "last_name": "simon", "age": 34, "city": "new-york"}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/cortex-xdr-xql/functions/object_merge.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
