Customer customer = new Cliente(4);
In the code an object customer is created locating through IdCliente = 4
How would to create an object customer that possesses a primary key composed, to idEmpresa and idCliente?
I think you're asking if you can load an subsonic object that has a composite key.
Customer customer = new SubSonic.Select()
.From(Customer.Schema)
.Where(Customer.IdEmpresaColumn).IsEqualTo(idEmpresa)
.And(Customer.IdClienteColumn).IsEqualTo(idCliente)
.ExecuteSingle();

I would like to know how the PersonID string (obtained after a call to the PersonGroup Person – Create method of the Face API) is computed. In particular, I would like to know if any information (such as the fields “name” and “userData” for example) can be recovered from it without calling the specific API function Person Group Person – Get.
Thanks in advance.
PersonID string is just a GUID here . If you create a persion, Azure Face service will provide you with an GUID as the ID of that person. As an identifier , PersonID has none business with person details such as “name” and “userData” .
If you want to get some info of a persion , I am afraid using API function Person Group Person – Get is the only way .
If you mean getting the information back that you put into the create() method parameters, yes you can get that from the client.person_group_person.create() results.
The create() method of PersonGroupPerson has the following fields as parameters: person_group_id, name, user_data, custom_headers, raw, and operation_config. So you can add values to those when you create a new PersonGroupPerson. Once this method is called, a Person object is returned with these properties: name, user_data, person_id, persisted_face_ids. So for example, this is what you could do:
# Create a new Person object and add that image to it.
new_person = client.person_group_person.create(person_group_id, name)
img = open(image_name, 'rb')
# Add the new person to your Person object and your person group
face_client.person_group_person.add_face_from_stream(person_group_id, new_person.person_id, img)
print('New Person Created:', new_person.name)
In the above example, you get person_id and name from the results of your create() call. So, whatever parameters you add in create(), can be retrieved from the result.
However, this is just general Person information, you have not yet added images (faces) of this person to this Person object yet, unless you call add_face_from_stream() or add_face_from_url().
If you are wondering how the person ID is created, Microsoft has some of their source code available in Github.

Do you know is there any like a global reference book of MS CRM entities in the system?
I need to resolve entity id to the entity type without checking every single entity for presence of given GUID.
Is it possible?
I don't know of any supported way, but I believe you could to a SQL query on the PrincipalObjectAccess table in the database and retrieve the value of ObjectTypeCode where ObjectId is the GUID.
For annotation you need to look at the field objecttypecode to determine the entity type of objectid.
You can either generate a list of entity logical names and object type codes in your code as a Dictionary object (this will give you the fastest performance but requires you know all the entity types that will be in the system at the time you compile) or (if you are on CRM 2011 UR12+ or CRM 2013) you can do a MetadataQuery.
You can read more about doing a metadata query here: http://bingsoft.wordpress.com/2013/01/11/crm-2011-metadata-query-enhancements/
Sample code for your requirement:
var objTypeCode = [INTEGER] //Make this this the annotation.objecttypecode
MetadataFilterExpression entityFilter = new MetadataFilterExpression(LogicalOperator.And);
EntityFilter.Conditions.Add(new MetadataConditionExpression("ObjectTypeCode", MetadataConditionOperator.Equals, objTypeCode);
EntityQueryExpression entityQueryExpression = new EntityQueryExpression()
{
Criteria = entityFilter
};
RetrieveMetadataChangesRequest retrieveMetadataChangesRequest = new RetrieveMetadataChangesRequest()
{
Query = entityQueryExpression,
ClientVersionStamp = null
};
RetrieveMetadataChangesResponse response = (RetrieveMetadataChangesResponse)orgService.Execute(retrieveMetadataChangesRequest);
You can reduce the metadata retrieved, for better performance, as shown here: How to get the CRM Entity Name from the Object Type Code of a RegardingID?
Background: Project is a Data Import utility for importing data from tsv files into a EF5 DB through DbContext.
Problem: I need to do a lookup for ForeignKeys while doing the import. I have a way to do that but the retrieval if the ID is not functioning.
So I have a TSV file example will be
Code Name MyFKTableId
codevalue namevalue select * from MyFKTable where Code = 'SE'
So when I process the file and Find a '...Id' column I know I need to do a lookup to find the FK The '...' is always the entity type so this is super simple. The problem I have is that I don't have access to the properties of the results of foundEntity
string childEntity = column.Substring(0, column.Length - 2);
DbEntityEntry recordType = myContext.Entry(childEntity.GetEntityOfReflectedType());
DbSqlQuery foundEntity = myContext.Set(recordType.Entity.GetType()).SqlQuery(dr[column])
Any suggestion would be appreciated. I need to keep this generic so we can't use known type casting. The Id Property accessible from IBaseEntity so I can cast that, but all other entity types must be not be fixed
Note: The SQL in the MyFKTableId value is not a requirement. If there is a better option allowing to get away from SqlQuery() I would be open to suggestions.
SOLVED:
Ok What I did was create a Class called IdClass that only has a Guid Property for Id. Modified my sql to only return the Id. Then implemented the SqlQuery(sql) call on the Database rather than the Set([Type]).SqlQuery(sql) like so.
IdClass x = ImportFactory.AuthoringContext.Database.SqlQuery<IdClass>(sql).FirstOrDefault();

Objective:
I have a table called Publication that contains Id, RecordId, EntityType and a couple other columns. I select all the records that need to be published to another database from that table. I then loop that collection to process the records and move the records to the other db.
Background:
The EntityType column is used to Identify the Set that the context needs to retrieve. I also use reflection to create a object of that type to see if it implements a certain type of interface. If the record being processed does implement that interface then I know that the RecordId for that record in the Publication table is not a PK in the Set() but rather a FK.
this code works fine when I am going after the PK values for EntityTypes that do not inherit the specific interface.
object authoringRecordVersion = PublishingFactory.AuthoringContext.Set(recordType.Entity.GetType()).Find(record.RecordId);
Problem:
DbContext.Set(EntityType).Find(PK) goes after the PrimaryKey value. How can I tell Set() to search like this sudo code example since 'Where' is not allowed
object authoringRecordVersion = PublishingFactory.AuthoringContext.Set(recordType.Entity.GetType()).Where(c => c.HeaderRecordId == record.RecordId)
Update:
I am working on Implementing the following. Will advise results tomorrow
var sql = "SELECT * from " + record.Entity + " WHERE HeaderRecordId = '" + record.RecordId + "'";
authoringRecordVersion = PublishingFactory.AuthoringContext.Set(recordType.Entity.GetType()).SqlQuery(sql).AsNoTracking();
.SqlQuery(sql).AsNoTracking();
does work effectively. Don't know why I didn't see this earlier.
I'm currently working with the versant object database (using jvi), and have a case where I need to query the database based on an object id.
The problem is I'm running some performance tests on the database using the pole position framework, and one of the tests in that framework requires me to fetch an object from the database using either an object reference or a low level object id. Thus, I'm not allowed to reference specific fields in the employee object, but must perform the query on the object in its entirety. So, it's not allowed for me to go "select * from Employee e where e.id = 4", I need it to use the entire object.
What I'm trying to achieve is something along the lines of
Employee employee = new Employee("Mr. Pickles");
session.commit();
FundVQLQuery q = new FundVQLQuery(session,
"select * from Employee employee where employee = $1");
q.bind(employee);
q.execute();
However, this throws an EVJ_NOT_A_VALID_KEY_TYPE error. Does anyone know the correct way of doing this?
Sure you figured this out (post was months ago). What you want to do is use the GetObjectId first, to get the VOD Id of the object, then query the DB;
id = session.GetObjectId(employee);
This is how I did the whole roundtrip object → OID → object:
First you get the OID with TransSession.getOidAsLong.
TransSession session = ...;
Employee employee = new Employee("Mr. Pickles");
long oid = TransSession.getOidAsLong(employee);
session.commit();
Once you have the object ID, just grab the object from its Handle.
TransSession session = ...;
Employee employee = (Employee)session.returnHandleFromLong(oid).handleToObject();
No VQL needed.
Usually keys are integers and not strings. You are creating an Employee using just his name, perhaps the correct identifier to use is his employeeId. I need some more information on the table to know for sure.
You can try this,
FundVQLQuery vql = FundVQLQuery (session,
"select selfoid from Employee where name = $1");
vql.bind ("Mr. Pickles");
HandleEnumeration e = vql.execute ();
while ( e.hasmoreHandles() ) {
Handle handle = e.nexthandle();
}
It will return all Employees with the name "Mr. Pickles", Then loop through them.
