Hi;

I am calling a stored procedure from my delphi code as below:-
My procedure is being executed, the data is being committed to the DB, when I execute the code manually from the mySQL command line it executes and returns all 4 of my parameters, however in my Delphi code (below) the results are unassigned. When I step through the parameters I see the named parameters, but not their values?

Any ideas?

Delphi 2010 mydac ver 7.5.10




<snip>
with spLogon do
begin
ParamByName('in_Email').AsString := Trim(input.eMail);
ParamByName('in_Password').AsString := Trim(input.password);
ParamByName('in_IPaddress').AsString := Trim(input.ipAddress);
ParamByName('in_Browser').AsString := Trim(input.browser);
Execute;
// result.status := ParamByName('o_ClientStatus').AsString;
// result.userID := ParamByName('o_ClientUser').AsInteger;
// result.token := ParamByName('o_ClientToken').AsString;
result.clientID := ParamByName('Result').Value;

if assigned(spLogon.Params) then
begin
for Idx := 0 to spLogon.Params.Count - 1 do
begin
if (spLogon.Params[Idx].ParamType = ptOutput) then
spLogon.Params[Idx].Value := spLogon.ParamByName(spLogon.Params[Idx].Name).Value;
end;
end;

end;

We cannot reproduce the problem. Please provide us the script you used to create your stored procedure, as well as the SQL query for its calling.

My Stored Procedure is created as follows:-

I am not creating any SQL code to explicitly call the procedure, I am simply creating the component, assigning the connection, assigning the parameters, executing the procedure (from the delphi component and attempting to read from the components output parameters. The values of these parameters is NULL.

Please, try to download the latest MyDAC build (8.2.6) and check if this problem still exists.
