这是我的SQL:

IF (SELECT Status FROM dbo.Coupon WHERE Guid = @pGuid) = 0
BEGIN
    UPDATE
        dbo.Coupon

    SET
        Status = @pStatus   

    WHERE
        Guid = @pGuid

    RETURN 0    
END

ELSE

RETURN 1;

这是我的C#:

try
            {
                DbCommand command = db.GetStoredProcCommand("upd_Coupon_p");
                db.AddInParameter(command, "@pGuid", DbType.String, s);
                db.AddInParameter(command, "@pStatus", DbType.Byte, 1);
                ds = db.ExecuteDataSet(command);
             }

如何在代码中获得0或1的返回值？
