Dear Advisor !

I use Delphi 5.0 + SQL Server 7.0, ADO Component

I want to send a command to SQL, so i write a sqlstatement in window :
ADOCommandText := exec sp_password 'aaa', 'bbb', 'ccc'

It runs well. But i want to get the value return when calling a store procedure. In this case, I do not want to trap the error to know the know the value. i want to know how to call a store procedure in D5

Thank for all consider

You might wanna use the TADOCommand component. All you need
to do is set some of its properties such as the name of
the stored procedure as well the parameters to be passed to
the stored procedure.

The parameters are contained in a list of TParameter
objects. Each TParameter simply has a name and a value.
Once the stored procedure has been executed, the return
code is stored in Parameter number 0.
i.e ReturnCode := MyADOCommand.Parameters[0].Value;

If you like, i'll post a cool unit that I wrote to let
me call stored procedures really easily.
Whenever I'm workin with a new database, I just write a descendant class from the unit and add stored procedure
wrappers as I need them.

My code :

     s := 'exec sp_password ' + QuotedSTr('a') + ', ' + QuotedSTr('a') + ', ' + QuotedSTr('aaa') ;
     HopDongForm.ADOCommand.CommandText := s ;
     HopDongForm.ADOCommand.Execute ;

 t := HopDongForm.ADOCommand.Parameters[0].Value
   

The errorat the lastest line :

'List indext out of bounds (0)'

If i run that sqlstatemnet in SQL Query of SQL Server. It is Ok.

Please correct my code for me
