我有一个SQL查询
Select * from `products`
where (`product_company`='mad over donuts' OR
`product_company`= 'dunkin donuts')
AND (`flavour`='vanilla')
AND (355 < `price` < 561 ) ;
它提取的元素大于某个固定价格且低于某个固定价格。它还包括其他约束。但是当我运行这个SQL查询时它给了我一个
1064 - 您的SQL语法出错;检查与您的MySQL服务器版本相对应的手册,以便在'
products
附近使用正确的语法(product_company
='疯狂的甜甜圈'或'产品'在第1行。
我检查了我的sql语法,我似乎没有遇到问题。有人,拜托?

Select * from `products`
where (`product_company`='mad over donuts' OR
`product_company`= 'dunkin donuts')
AND (`flavour`='vanilla')
AND (355 < `price` < 561 )";
“导致问题
试试这个
Select * from `products`
where (`product_company`='mad over donuts' OR
`product_company`= 'dunkin donuts')
AND (`flavour`='vanilla')
AND (`price`BETWEEN 355 and 561 );
答案 1 :(得分:2)
更改
355 < price < 561)
到
price between 356 and 560
纠正问题(包括等于之间需要缩小范围)
即
Select * from `products`
where (`product_company`='mad over donuts' OR
`product_company`= 'dunkin donuts')
AND (`flavour`='vanilla')
AND price between 355 and 561

`product_company`= 'dunkin donuts')
AND (`flavour`='vanilla')
AND (`price` between 355 and 561 )" ;
