记录未使用 like 子句过滤

Question

使用以下查询过滤记录：

select * from SearchRecord where searchkeyword1  like  '[%'

也试过这个

select * from SearchRecord where searchkeyword1  like  '%[%'

表中的记录包含这些值（如下所示，我需要最后 2 条记录，为什么这个简单的喜欢不会过滤记录）

"Affiliate" means
"Agent's Rate of Exchange" means
["Aggregate Total Commitments" means
["Agreed Security Principles" means

Answer 1

您的搜索模式包含wildcard character [，您应该将其括在方括号中或ESCAPE character像这样使用：

declare @SearchRecord table (searchkeyword1 varchar(100));
insert into @SearchRecord values
('"Affiliate" means'),
('"Agent''''s Rate of Exchange" means'),
('["Aggregate Total Commitments" means'),
('["Agreed Security Principles" means');

select * 
from @SearchRecord 
where searchkeyword1  like  '![%' ESCAPE '!';

select * 
from @SearchRecord 
where searchkeyword1  like  '[[]%';

所有这些都在这里描述： LIKE (Transact-SQL)
