在存储过程中使用exec时有两个结果集

Question

我有一个存储过程，见下文，执行。在存储过程中是exec命令。当我执行存储过程时，我得到两个结果集，我的exec命令的结果，然后是返回值。如何从exec命令中获得结果？

DECLARE @openquery NVARCHAR(MAX)
DECLARE @tsql   NVARCHAR(MAX)
DECLARE @linkedserver NVARCHAR(10)

SET @linkedserver = 'orad'
SET @openquery = 'SELECT * FROM OPENQUERY(' + @linkedserver + ','''

SET @tsql = 'SELECT 
            COUNT(empl_id) AS emplcnt 
        FROM
            (
                SELECT 
                    empl_id,
                    empl_last_nm,
                    empl_first_nm,
                    empl_middle_init,
                    empl_pay_plan_cd,
                    empl_stat,
                    empl_typ,
                    empl_cctr_id,
                    empl_corporate_id,
                    empl_dir_chrg_ind,
                    LEVEL 
                FROM 
                    cdas.vdwhemp3 
                WHERE 
                    empl_stat in (''''ACTIVE    '''',''''DISABLED  '''',''''LEAVE     '''',''''MILITARY  '''',''''SALARY CON'''',''''UNKNOWN   '''') 
                START WITH 
                    empl_id = '''''+ @id + '''''
                CONNECT BY PRIOR 
                    empl_id = empl_empl_id 
                ORDER SIBLINGS BY 
                    empl_last_nm
            )'')'

EXEC (@openquery+@tsql)
