PATCH Query
In order to update data, a PATCH query may be defined, which allows updating specific (defined) values in an instance.
Similar to the PUT query, this is an elementary way for updating instances and usually not able to execute related actions. When, however, a method has been implemented for updating person data, one could also call the implemented method.
Field assignments are similar to PUT query. Only the query type differs:
|
Class/type |
Query/variable |
Source |
Comment |
|
Person/PATCH |
Update |
Persons |
Person collection |
|
name |
name |
Family name for person to be created | |
|
birth |
birth_date |
Person's birth date | |
|
married |
married |
Marital status |
The PATCH request generated from this mapping looks like:
Test: http://localhost:2000/query/PUT/Person/Create?
id=P124&&name=Hover&birth="1.1.1999"&married=false
PATCH
user
pwd
/Persons(?id)
{
name : ?name,
birth_date : ?birth,
married : ?married,
pid : ?id }
In case of success, the request returns an internal code 3 and a message:
{ code=3, message="Instance(s) updated" }
