分数字符串

Question

我有这个

SELECT ('130.067'||'****') as "WIN " FROM DUAL ;

我需要在每个数字和*之间添加一个空格（“”）来得到像这样的东西

“1 3 0。0 6 7 * * * *”

SQL Fiddle

查询1 ：

SELECT REGEXP_REPLACE(
         '130.067'||'****', -- String to match
         '([0-9.*])',       -- Match a digit or full stop or star
         ' \1',             -- Replace with space then matched character
         2                  -- Start at the 2nd character
       ) AS win
FROM   DUAL
