摘要:我们在使用sybase数据库的时候,经常使用excel通过程序读取excel读取内容然后插入到sybase数据库表中,在这个过程中经常会出现excel中存在换行符(看不到换行符),导入到表中后经常会因为换行符导致各种不同的错误,所以怎么快速的将/x0a直接去掉呢?首先怎么收索到包含/x0a,然后去掉/x0a。
 
1、收索存在/x0a或/X0A的字段
 
select * from xxxx  where userid like '%
 
%'(这里包含一个换行符)
 
2、将/x0a或/X0A去除
 
假设id为12595的数据存在换行符,sql如下:
 
update xxxx set userid=(
 select str_replace(userid,'
 ',null)  from xxxx where userid like '%
 %' and id=12595
 ) where id=12595
 
思路:先查询出12595对应当userid的值,然后通过str_replace函数将换行符替换掉,,最后通过update更新这条数据。
