理解样本数据的真实情况是很困难的（至少对我来说是这样）;有一个冒号（作为名称-值分隔符），什么都没有，有双引号。所以，我稍微调整了一下，到处都用冒号。
样本数据：

SQL> select * From test;

COL
--------------------------------------------------------------------------------
Age:40
City:
University Name:
Subject Name:
Match Percentage: 75%
Phone Number:

Age:12
City: Zagreb
University Name: FER
Subject Name: Maths
Match Percentage: 23%
Phone Number: 003851123456

查询：首先将每个列值拆分为单独的行，然后应用一个简单的case表达式，该表达式搜索冒号字符后面的任何内容。

SQL> with tsplit as
  2    (select rowid rid,
  3       column_value lvl,
  4       trim(regexp_substr(col, '[^' || chr(10) ||']+', 1, column_value)) val
  5     from test cross join
  6       table(cast(multiset(select level from dual
  7                           connect by level <= 6
  8                          ) as sys.odcinumberlist))
  9    )
 10  select
 11    max(case when lvl = 1 then substr(val, instr(val, ':') + 1) end) age,
 12    max(case when lvl = 2 then substr(val, instr(val, ':') + 1) end) city,
 13    max(case when lvl = 3 then substr(val, instr(val, ':') + 1) end) university,
 14    max(case when lvl = 4 then substr(val, instr(val, ':') + 1) end) subject,
 15    max(case when lvl = 5 then substr(val, instr(val, ':') + 1) end) match,
 16    max(case when lvl = 6 then substr(val, instr(val, ':') + 1) end) phone
 17  from tsplit
 18  group by rid;

AGE CITY       UNIVERSITY   SUBJECT    MATCH      PHONE

如果我的假设是错误的，那么调整query，使您不搜索冒号，而是分别搜索每个“name”字符串。但是，就总体思路而言，这可能是一种选择。
