Question

我需要使用Reg_replace函数删除Oracle String Data中除连字符和空格以外的所有特殊字符。请提供帮助。例如：

输入-> My Name is #name1 输出-> My Name is name1

输入-> this is my add-ress#" 输出-> this is my add-ress

输入-> can we remov-e this'; 输出-> can we remov-e this

Answer 1

您可以使用[^[:alnum:] -]作为正则表达式来匹配要替换的值。

Oracle设置：

CREATE TABLE test_data( value ) AS
  SELECT 'this is my add-ress#\' FROM DUAL UNION ALL
  SELECT 'My Name is #name1' FROM DUAL UNION ALL
  SELECT 'can we remov-e this' FROM DUAL;

查询：

SELECT value,
       REGEXP_REPLACE( value, '[^[:alnum:] -]', NULL ) AS replaced_value
FROM   test_data

输出：

VALUE                 | REPLACED_VALUE     
:-------------------- | :------------------
this is my add-ress#\ | this is my add-ress
My Name is #name1     | My Name is name1   
can we remov-e this   | can we remov-e this

Answer 2

您可以使用以下

with t(str) as
(
 select 'this is my add-ress#&%! : 198' from dual
)
select regexp_replace(str,'[^-0-9A-Za-z ]','') as "Result String"
  from t;

Result String
-----------------------
this is my add-ress  198
