select 查询中判断字符串格式

[xk_su]

我有一个select 查询语句，其中有一栏，我想让它只含有字母和数字，怎样过滤

ID ITEM
ASD3 000
A SD 023
A#pk 5


比如上面结果，我想要ID栏只含有字母和数字的结果，其它的比如空格，#等都过滤

oracle有没有类似的函数可以过滤下

正则匹配过滤 regexp_like

with t as
(
select 'ASD3' ID,'000' ITEM from dual
union all
select 'A SD','023' from dual
union all
select 'A#pk','5' from dual
union all
select ' ','5' from dual
)select * from t where regexp_like(id, '^([a-z]|[A-Z]|[0-9])*$');   --只包含大小字母或数字

with t as
(
select 'ASD3' ID,'000' ITEM from dual
union all
select 'A SD','023' from dual
union all
select 'A#pk','5' from dual
union all
select ' ','5' from dual
)select * from t where regexp_like(id, '^([a-z]|[A-Z]|[0-9])*$');   

ID   ITEM
---- ----
ASD3 000
