数据库中使用正则表达式
数据库中有一个字段有Tb23456，TBS123456,tasd1234,DFS1243456这些类型，过滤掉只要Tb23456这个类型的呢？
[解决办法]
如果你那些以逗号为间隔每行显示的话，直接where里面登于Tb23456就可以拉
[解决办法]

select * from 表 where 字段='Tb23456'

select * from 表 where left(字段,2) = 'Tb'

select * from [表名] 
 where patindex('tb%',[字段])>0 and 
       patindex('tbs%',[字段]) =0

--> 测试数据：[huang]
if object_id('[huang]') is not null drop table [huang]
go 
create table [huang]([a] varchar(10))
insert [huang]
select 'Tb23456' union all
select 'TBS123456' union ALL
select 'tasd1234' union all
select 'DFS1243456'
--------------开始查询--------------------------

select * from [huang] WHERE a LIKE 'tb[0-9]%'
