sql - 测试函数的多个值

Question

我正在尝试测试一个函数(在本例中 - regexp_replace(tvalue,'([[:cntrl:]])',''))并且想知道是否有办法通过多个输入数据到一个 SQL 查询中的函数？

基本上我想看到一个函数正在替换不可打印的字符，我的想法如下所示:

我的伪代码:

with testdata as (select 
'teststring1',
'$kfjs',
chr(10)||'test',
'    <>',
null,
'[{}&,''/\'
from dual)
select tvalue, regexp_replace(tvalue,'([[:cntrl:]])','')  from testdata
where tvalue <> regexp_replace(tvalue,'([[:cntrl:]])','');

Answer 1

with testdata as (
  select 'teststring1' as tvalue from dual
  union all
  select '$kfjs' from dual
  union all
  select 'str1' || chr(10) || 'str2' from dual
  union all
  select '    <>' from dual
  union all
  select null from dual
  union all
  select '[{}&,''/' from dual
)
select rownum, tvalue, regexp_replace(tvalue, '([[:cntrl:]])', '') from testdata
where tvalue <> regexp_replace(tvalue, '([[:cntrl:]])', '');
