How to retrive data to QSqlQueryModel When Excute a SQL Procdure?

I Create a procdure in SQL Server 2005

Code:

---

CREATE PROC procs_model_data_test
AS
BEGIN
   -- Do something
   ...
   --At the end,show the result.
   SELECT * FROM tbl_model_data_test
END

---

When Execute such proc in the Qt Program

Code:

---

QString szSQL = "EXEC procs_model_data_test";
QSqlQueryModel model;
model.setQuery(szSQL);

---

However , the model has no records, do you have any idea? thank you!
