Question

我有一个包含LastName和FirstName的Person表。

考虑以下记录

FirstName =='Pete'和LastName =='Aaaa'

当我运行以下select语句时：

select * from Person where FirstName='Pete' and LastName like 'a%' -- 0 record returned
select * from Person where FirstName='Pete' and LastName like 'aa%' -- 1 record returned
select * from Person where FirstName='Pete' and LastName like 'aaa%' -- 0 record returned
select * from Person where FirstName='Pete' and LastName like 'aaaa%' -- 1 record returned

当我在SQL Fiddle中运行时 - 为每个选择返回1条记录，因为它应该 SQL Fiddle query

有人有什么想法吗？

Answer 1

试试这个

select * from Person where FirstName='Pete' and LastName collate Latin1_General_CI_AS like 'a%'
select * from Person where FirstName='Pete' and LastName collate Latin1_General_CI_AS like 'aa%'
select * from Person where FirstName='Pete' and LastName collate Latin1_General_CI_AS like 'aaa%'
select * from Person where FirstName='Pete' and LastName collate Latin1_General_CI_AS like 'aaaa%'

SQL LIKE没有返回正确的结果
