取得存储过程的返回值、输出参数

 带输出参数的:
            try
            {
                Database db 
= DatabaseFactory.CreateDatabase();
                DbCommand cmd 
= db.GetStoredProcCommand("usp_xxx");

                db.AddParameter(cmd, 
"@UserID", DbType.Int32, ParameterDirection.InputOutput, "", DataRowVersion.Current, dict.Get("UserID"0));
                db.AddInParameter(cmd, 
"@LoginName", DbType.String, dict["LoginName"]);
                

                db.ExecuteNonQuery(cmd);
                
return DictionaryEx.Create("UserID", db.GetParameterValue(cmd, "@UserID"));
            }
            
catch (Exception)
            {
                
return null;
            }        



带返回值:
try
            {
                Database db 
= DatabaseFactory.CreateDatabase();
                DbCommand cmd 
= db.GetStoredProcCommand("usp_xxx");
                db.AddInParameter(cmd, 
"@UserID", DbType.Int32, dict["UserID"]);
                
                db.AddParameter(cmd, 
"@ret", DbType.Int32, ParameterDirection.ReturnValue, "", DataRowVersion.Default, null);
                db.ExecuteNonQuery(cmd);

                
return cmd.Parameters["@ret"].Value;
            }
            
catch (Exception)
            {
                
return null;
            }



查询返回结果集:
try
            {
                Database db 
= DatabaseFactory.CreateDatabase();
                DbCommand cmd 
= db.GetStoredProcCommand("usp_xxx");
                db.AddInParameter(cmd, 
"@rowStart", DbType.Int32, dict.Get("rowStart"null));
                db.AddInParameter(cmd, 
"@rowEnd", DbType.Int32, dict.Get("rowEnd"null));

                
return db.ExecuteDataSet(cmd);
            }
            
catch (Exception)
            {
                
return null;
            }
