select * from t_bd_item_info  where charindex(char(8),item_name) > 0 
go


--查询名称有制表符tab 
select * from t_bd_item_info  where charindex(char(9),item_name) > 0 
go
--查询名称有换行  
select * from t_bd_item_info where charindex(char(10),item_name) > 0 
go
--查询名称有回车  
select * from t_bd_item_info where charindex(char(13),item_name) > 0 
go
--查询名称的空格（前空格、后空格、所有空格）
select * from t_bd_item_info where isnull(charindex(' ',item_name),0) > 0   
go
--查询名称的单引号 
select * from t_bd_item_info where charindex(char(39),item_name) > 0 
go
--查询名称的双单引号 
select * from t_bd_item_info where charindex(char(34),item_name) > 0 
go




--处理名称有退格键
update t_bd_item_info set item_name = replace(item_name,char(8),'') 
where charindex(char(9),item_name) > 0 
go


--处理名称有制表符tab 
update t_bd_item_info set item_name = replace(item_name,char(9),'') 
where charindex(char(9),item_name) > 0 
go

update t_bd_item_info set item_name = replace(item_name,char(10),'') 
where charindex(char(10),item_name) > 0 
go

go
--处理名称的空格（前空格、后空格、所有空格）
update t_bd_item_info set item_name = replace(rtrim(ltrim(item_name)),' ','')  
where isnull(charindex(' ',item_name),0) > 0   
go
--处理名称的单引号
