From within the .xsd designer I drag a table from a MySql connection on the list and begin configure it. When I open the Advanced Query builder, The sql is changed from what was in the initial box

   select * from x;


   select * from def.schema.x

where schema is the actual schema and the problem is that I don't understand where the def prefix is coming from which causes the SQL to be invalid. 

Using MySql version 5.5.8, MySqlConnector 6.3.4, Visual Studio 2008, Windows 7 64. This same process was working fine on XP.

Any ideas?

How to repeat:
please see description.

Suggested fix:
Determine where the "def" would possibly be inserted from, offer workaround if there is one.

Please, check if the same problem happens with a newer version of Connector/Net, 6.3.6.

It disappeared in the following situation:

I was using a connection string saved in the settings of the app.
I went to one tableadapter of the dataset and to the properties of the tableadapter. There I changed the connection to "localhost". The program asked me to save the connection in app settings, I said yes, then it disapeared.
Then I changed again to previous saved connection string, deleted from settings the created connection string and still working fine.. Really strange behaviour..

I had other datasets in other projects of the solution. It disappeared on all the projects of the solution.

Ok, discovered it has to do with the catalog: 

Go to vs2008."servers explorer".
Select a view of the database wich I created the conection.
Go to properties it appears, (READ ONLY all the properties):

Catalog: def                    <------ !!
Check Option: NONE
Definer: root@localhost
Definition: select(...)
Is Updatable: YES
Name: muestrasaretirar
Schema: schemaname              <------ !!
Security Type: DEFINER

Now 'Catalog=def' only appears in the properties of a view.
Before it also appeared the properties of a table also (Now in a table properties 'Catalog=""').
Now the query builder only adds "def.schemaname" when trying to add a view.

Tried to generate again the connection, to change the name of the connection, to change all the connections of the dataset. No way.
