我用下面语句查询只得到了3个结果 部门号为30的结果没显示出来 上面的查询显示字符串的长度怎么会不一样
select data
from V
where translate(lower(data),
'0123456789abcdefghijklmnopqrstuvwxyz',
rpad('a',36,'a'))=rpad('a',length(data),'a')
CLARK
KING
MILLER
------解决方案--------------------
select data,lengthb(translate(lower(data),
'1234567890qwertyuiopasdfghjklzxcvbnm',
rpad('a',36,'a') )) translated
, lengthb(rpad('a',length(data),'a')) fixed
from V
看下长度
------解决方案--------------------
现在人气不行了 又看回来咯 还是举个例子吧
将数字字符替换成空 如果整体为空 那这字符串就是字符数字类型 如果不为空 就夹杂其他特殊字符
with t1 as
(
select 'asdf234' c1 from dual
union all
select 'asdf334#@sdf' from dual
union all
select 'a23423ds' from dual
union all
select 'a<>?sdf' from dual
)
select c1
from t1
where REGEXP_REPLACE(c1,'[0-9
------解决方案--------------------
a-z
------解决方案--------------------
A-Z]','') is null;
c1
-----------------------------
1 asdf234
2 a23423ds
