I used the following code in progs compiled with
delphi 5, delphi7 and delphi 2007 with winxp sp1 to win 7
with MSsql2000 and MSsql2005 without problem
Listbox1.Clear;
Query1.sql.Clear;
Query1.sql.add('exec Aufnahme.dbo.L_Stat_Allgemein');
Query1.open;
while not Query1.eof do
begin
Listbox1.Items.Add(Query1.findfield('GSJ').AsString + ' - ' +
Query1.findfield('Statistik').AsString );
Query1.Next;
end;
Query1.Close;
exists query.updatemode in lazarus ? then it should be upWhereAll, because
the exec or execute has no key
next switch on logging odbc
and a diff of two logs between delphi prog and lazarus prog with one query with
exec
