I have a stored procudure in SQL Server with 3 parameters:
        pa varchar(10)
        pb varchar(20)
        pc smallInt OUTPUT
and therefore I creaet a stored procedure in Delphi with parameters
        @pa     INPUT
        @pb     INPUT
        @pc     INPUT/OUTPUT
when I try to call it from Delphi, it keeps coming out an error message.
If I bind the parameters by name, it says "Parameter 'pa' not found";
if I bind the parameters by number, it says "Invalid parameter".
What can I do with this? Any advices are appriciated.

When you set DatabaseName and StoredProcName properties
in Object Inspector try to set Active=True. If it fails then you
didn't set Params property in this stored procedure. Choice
this property Params and set all TYPES and null values for all
parameters.
It seems to me that Delphi can pass Params without type casting. If Params[0] is Integer I set it's value
 MyProc.Params[0].AsInteger := 1;

and not

MyProc.Params[0].AsString := '1';

Regards!
