每次只需查询都输出大量日志，影响正常使用。

[na57]

每次查询都会有大量日志输出：

getShopBill: Executing select shopname as shopName, accdate as accDate, transcnt as transCnt, dramt as drAmt, cramt as crAmt from t_shop_bill where shopname=(select distinct shopname from t_shop where shopid="undefined") and accdate="20170109";
Executing select shopname as shopName, accdate as accDate, transcnt as transCnt, dramt as drAmt, cramt as crAmt from t_shop_bill where shopname=(select distinct shopname from t_shop where shopid="undefined") and accdate="20170109"; return empty result

应该设置一个开关，用来指定是否输出日志。
