Question

我有一个非常简单的查询返回结果，我很确定不应该包含它。

CREATE TABLE hits
AS SELECT *
FROM deduped_table
WHERE Bank LIKE '%monex%' OR Bank LIKE '%cibanco%' OR Bank LIKE '%intercam%'
AND (Bank_Country = 'US' OR Bank_Country = 'United States');

当我查看点击表时，Bank_Country列的结果不是“美国”或“美国”。为什么呢？

Answer 1

添加括号以显示SQL's precedence rules，您的查询为：

SELECT *
FROM deduped_table
WHERE Bank LIKE '%monex%'
   OR Bank LIKE '%cibanco%'
   OR (Bank LIKE '%intercam%' AND
       (Bank_Country = 'US' OR Bank_Country = 'United States'));

Answer 2

要完成@CL。答案，您的查询应该阅读

fun()

SQLite WHERE子句被忽略
