| ### Syntax | ||
|
|
||
| The `field_expression` parameter is required. The `path_expression` parameter is optional. Dot notation is used to show the nesting level for both the `field_expression` and `path_expression` parameters. For example, `nestedObj.innerFieldName` denotes a field nested one level. If the user does not provide the `path_expression` parameter, the path value is generated dynamically. For example, the field `user.office.cubicle` would dynamically generate the path `user.office`. The syntax is shown in the following example: |

||
| ### Boolean condition inside the nested function |
| ``` | ||
| {% include copy.html %} | ||
|
|
||
| ### Nested function with predicate expression and literal expression |

||
| ## Using the function in aggregation queries | ||
|
|
||
| Nested fields can be aggregated in the `GROUP BY` clause and filtered in the `HAVING` clause using the `nested` function within SQL queries. |
|
|
||
| #### Example query | ||
|
|
||
| The following are examples of a query using nested queries in the `GROUP BY` and `HAVING` clauses: |
