Question

我有以下mySQL语句，这是不正确的。

SELECT id, location__, image__, bedrooms, bathrooms, price__ 
FROM myTable 
WHERE LOWER(location__) REGEXP '.london.' 
AND (bedrooms >=2) 
AND (bathrooms == true) 
ORDER BY price__  DESC 
LIMIT 0,20;

如何格式化在PHP中工作的SQL查询，以便我可以比较卧室＆gt; 2和浴室＆gt; 2 AND ensuites = 1（即true）......等

Answer 1

您只需要使用AND添加条件，以满足您的要求。

SELECT id, location__, image__, bedrooms, bathrooms, price__ 
FROM myTable 
WHERE LOWER(location__) REGEXP '.london.' 
AND bedrooms >=2
AND bathrooms >=2 and ensuites = 1
ORDER BY price__  DESC 
LIMIT 0,20;

Answer 2

您可能在浴室中使用了错误的SQL比较运算符。在SQL中，您可以使用单个等号进行比较：

SELECT id, location__, image__, bedrooms, bathrooms, price__ 
FROM myTable 
WHERE LOWER(location__) REGEXP '.london.' 
AND bedrooms >= 2 
AND bathrooms = 1 
ORDER BY price__  DESC 
LIMIT 0,20;

WHERE语句中的mySQL多重AND比较
