Using TQuery, get Return code from SQL Server

I'm using Delphi 4.0 and SQL Server 7.0.  The problem is I don't know how to get the return code returned by a stored procedure from SQL Server, using TQuery.

Do you require a live datset in your app or is it a readonly result set ?

With TStoredProc's you can return results to Delphi by using the TStoredProc.Open call and when you only want to execute a set of command you use TStoredProc.ExecProc.  The ExecProc enables you to access the return value of the procedure.

Note, in using a Tstoredproc to return a result set you must have the corresponding SELECT statement in the stored procedure.  This has got to be preferable in cases where a Non-Editable resultset is required (for example reporting) because if changes are required they can be done on the server side.  

In the documentation it says that cached updates can be used with TStoredProc's but as yet I haven't tried so I don't know if this is true or not.

As far as I know, you need to use the TStoredproc object for all stored procedure calls. The return value is stored in the params of the object.

Assuming that you have not tried this: If you want to you can try and do an execsql - using a TQuery - and check the return value, but never having done this, I cannot place any faith in whether this will work...

I'm using TQuery for scalability.  One of the experts told me that for TQuery is more flexible that TStoredProc.  In using TQuery, I use 'open' to get values from my query, and 'execsql' whenever I don't need any feedback from sql server.  However, I'm wondering if I can get the return code from a stored procedure through TQuery.
