---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  
    update t_bd_item_info set item_name = replace(item_name,char(10),'') 
    where charindex(char(10),item_name) > 0 
    go
    --处理名称有回车  
    update t_bd_item_info set item_name = replace(item_name,char(13),'') 
    where charindex(char(13),item_name) > 0 
    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 
    update t_bd_item_info set item_name = replace(item_name,char(39),'') 
    where charindex(char(39),item_name) > 0 
    go
    --处理名称的双单引号 
    update t_bd_item_info set item_name = replace(item_name,char(34),'') 
    where charindex(char(34),item_name) > 0 
    go
