# Get by key

An entity set typically has a 'Get by key'-operation. As input it takes the key(s) of the entity.

## Output

The result (a record) of the operation looks like this:

* StatusCode - the HTTP status code returned from the OData endpoint, typically **201** if the operation was successful. A value of 0 or -1 indicates a problem in the connector (i.e, no request sent to the OData endpoint)
* ErrorMessage - has no value if the operation succeeded, otherwise a description of what when wrong
* HasFailed - simple value containing true if operation failed
* Entity - a record containing the values of the created entity, including the values of auto-generated columns.
* Descriptor - is omitted by default, but if included,  contains OData-related information about the entity, such as ETag
* Headers - is omitted by default, but if included, contains all HTTP headers returned by the OData endpoint
