Hi

In some old designs (BDE)  we were used to reuse the
Query to like this :

qry := TQuery.Create(nil);
...
...
qry.SQL.Text := 'SELECT cprnr FROM xxx';
some parameter set up etc.
open
use the return dataset

qry.close;
qry.sql.text := 'Insert into bla bla.. with some parameters';
qry.sqlexec;

now the ADO Parameter do not clear the parameters on close or then sql.text
are set again,
so Ado comes up with an error indicating that parameters are not correct .

Why in world are parameters not cleared when the qry text are changed.
Am I missing something here ?

Best regards
Kim Pedersen
