MySQL:比较运算符不工作

Question

我正在使用以下代码.它工作正常,但当我使用日期过滤器时,它停止工作.我在sql中使用了比较运算符.我搜索了一些问题,但没有找到理想的答案.

        SELECT SUM(retailerData.poster), SUM(retailerData.banners), SUM(retailerData.tradeLetters), SUM(retailerData.stickers) , 
    SUM(retailerData.buntings),SUM(retailerData.dangler) FROM retailerData INNER 
    JOIN retailer ON retailer.retailerID=retailerData.retailerID WHERE
   '2016-08- 24'<= retailerData.visitDate <='2016-09-03' 
    AND retailer.retailerID IN( SELECT 
    retailer.retailerID FROM retailer INNER JOIN office ON office.officeID= 
    retailer.officeID WHERE office.officeID IN( SELECT officeID FROM office          
    WHERE 
    parentOfficeID IN( SELECT officeID FROM office WHERE parentOfficeID IN    
    (SELECT 
    officeID FROM office WHERE officeName='Faisalabad Belt') ) ))

请帮我解决这个问题.

Answer 1

你有这个条件:

WHERE '2016-08- 24'<= retailerData.visitDate <= '2016-09-03' 

在大多数方言中,这不是标准的 - 既不是三元运算符也不是日期文字中的空格.

试试这个:

WHERE '2016-08-24'<= retailerData.visitDate AND
      retailerData.visitDate <= '2016-09-03'
