I have a stranger thing case with the data read and the ODBC connections.
The thing is that when I try to configure a data reader, I can use all the tables in the RDB area but one: the "User" table.
The error message says: Table 'User' is empty.
The table is not empty and if I try to select the other tables there is no problem with the connection.
Also, I have no problems with the manual query to call the User table for the data read (obviously the table is not empty so the error message is senseless)... but that is a bit annoying for me and I do not know why this error happens only with this table.
