过滤日期时的多个OR语句SQL Server 2008

Question

以下查询正确运行，但未添加其他"OR"参数。

由于某种原因，SC和CC的查询结果未格式化为WHERE子句，并将多个日期返回给我的参数之外。我应该如何更改此语法以确保我的WHERE子句影响OR语句？

SELECT DISTINCT case_number, case_filed_date 
FROM [case] 
WHERE case_filed_date BETWEEN '2012/07/01' AND '2012/09/30' 
AND case_number LIKE '%CA%' OR case_number LIKE '%SC%' OR case_number LIKE '%CC%' 

Answer 1

试试这个使用括号为AND具有更高的优先级高于OR： -

SELECT DISTINCT case_number, case_filed_date 
FROM [case] 
WHERE case_filed_date BETWEEN '2012/07/01' AND '2012/09/30' 
AND 
(case_number LIKE '%CA%' OR case_number LIKE '%SC%' OR case_number LIKE '%CC%') 

Answer 2

添加括号

SELECT DISTINCT case_number, case_filed_date 
FROM [case] 
WHERE case_filed_date BETWEEN '2012/07/01' AND '2012/09/30' 
AND 
(
    case_number LIKE '%CA%' OR case_number LIKE '%SC%' OR case_number LIKE '%CC%' 
) 

and结合强于or
