---如下是查询语句

--查询名称有退格键

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

--处理名称有换行

where charindex(char(10),item_name) > 0

where charindex(char(13),item_name) > 0
