Description
The Query Attachments operation is performed on a map service layer resource. The result of this operation are attachments grouped by the source feature object Ids and global ids (if exist).
Queries must include one of the following parameters: object , global , or definition . All other parameters are optional and are used to further refine the returned results.
You can provide arguments to the Query Attachments operation as query parameters defined in the following parameters table:
New at 10.8.1
- Field names are now returned in addition to the field properties in the
queryoperation response. If the field name and property name match, including case, only one value is returned in the response to represent both field and property. As a best practice, it is best to go by the fieldname rather than the property when consuming this in an application.Attachments - When using the
attachmentsparameter, you can use theDefinition Expression fieldproperty from the layer'sName attachmentobject. This describes the names of the fields that can be used in the expression. The layer'sProperties attachmentobject lists more information about these fields, including type, which can be useful when building queries. This information is not provided in the layer resource at earlier releases, but the same field names can be used in those as well.Fields

Example usage
Example one
The example below demonstrates how to query attachments using the parent objects . The query results will return only the specified object ids.

The example below demonstrates how to query attachments using the parent global . The query results will returns only the specified global ids.

The example below demonstrates how to query attachments using the definition as objectid and attachment as impage /jpeg. The query results will return all image/jpeg attachment types where the object id is greater than 2.

The example below demonstrates how to query attachments using the definition STATE as 'alaska' , result as 5, and result as 10. The query results will skip the first 5 records and return the next 10 attachments in Alaska.
https://machine.domain.com/webadaptor/rest/services/light-inventory/MapServer/0/queryAttachments?objectIds=2&globalIds=&definitionExpression=STATE_NAME = 'alaska'&attachmentTypes=&size=&resultOffset=5&resultRecordCount=10&f=htmlExample five
The example below demonstrates how to query attachments using the attachments ATT as 'alaska and size as 900,7000 . The query results will return all attachments within the specified file size range with the attachment name 'alaska.geodatabase' .
https://machine.domain.com/webadaptor/rest/services/light-inventory/MapServer/0/queryAttachments?objectIds=2&globalIds=&definitionExpression=ATT_NAME = 'alaska.geodatabase'&attachmentTypes=&size=900,7000&resultOffset=&resultRecordCount=&f=htmlExample six
The example below demonstrates how to query attachments using the definition STATE as 'alaska' , size as 900,7000 , and return as true . The query results will return all attachments, including URLs, within the specified file size range in Alaska.
https://machine.domain.com/webadaptor/rest/services/light-inventory/MapServer/0/queryAttachments?objectIds=2&globalIds=&definitionExpression=STATE_NAME = 'alaska'&attachmentTypes=&size=900,7000&resultOffset=&resultRecordCount=&returnUrl=true&f=htmlExample seven
The example below demonstrates how to query attachments using the definitionExpression as 1=1 and keywords as 'motorcycle'. The query results will return all attachment types that have a keywords value of motorcycle.
