Hello, in using ADOExpress components.
 I work with a TADOConnection and a TADOQuery * q linked to it.
 If the connection is closed and I set q->SQL->Add("SELECT ..") the
component
 activates the connection raising an error if the server isn't
reachable.
Also if I clean the ConnectionString, it restores the old string and
forces the connection!
 I know that it's possible to set the sql property just before executing
it,
 but I would like to know the reasons why the object needs to access the
database at this time.
 Thank you !
 andrea
