Bug #52085 MySQL Connector /Net

Description:
I have a table in MySQL with two fields:
table: session
 - sessionId char(36)
 - name      varchar(45)

When a import the data model, by ADO.net Entity Framework, my table shows ok, with the field sessionId as Guid. OK.

But I have a view in database and this view not show the filed as Guid, but as String. I try change this type but not work.

The view is:
select sessionId, name from session

How to repeat:
Create a table with the two fields.
Create a view with the two fields.
Import the model by Entity Framework.
See the table field as Guid and the filed view as String.

Suggested fix:
That the view propertie show as Guid in model.

Hi Rodrigo and thanks for your report.

Verified as described using c/NET 6.2.2:
Server version: 5.1.31-log MySQL Community Server (GPL)
create table bug52085 (
  sessionId char(36) not null primary key, 
  name varchar(45));

create view vbug52085 as select * from bug52085;

Server returned metadata is consistent:

EF model maps sessionId (table) to GUID while sessionId (view) is mapped as String.

Exactly. And in my application I need the resource view to display data and link to the entries, but the type has to be Guid and not String. Thank you.

Reggie Burnett, this error has some expected to be corrected? How is the process? Thank you.
