Question

我已经问了这个问题，但我不确定为什么没有人回答。我得到了一个部分答案，也许是因为我把它标记为正确答案......不确定，但会再次试试我的运气。

我的数据如下：

reported_name
--------------

HEMA using TM-0497
TEGDMA
Blue HEMA using TM-0510
Norbloc using TM-0545
SIMAA2 using TM-0547

Haze using TM-0561
Blue HEMA using CRM-0126
t-Amyl Alcohol
Transmittance TM-0509
DK (edge corrected) TM-0534
Decanoic Acid CRM-0200
Glycol using CRM-0094
% Ketotifen Released using TM-0578_V2_RELEASE
TMPTMA using CRM-0208
% Ketotifen Released using TM-0578_V2_RE
Ca2DTPA Assay using USP_541 (3 day drying)
Water using TM-0449 OOS Analyst 1, Equip 1, set 2
Leachable Polymer using CRM-0225 Sample B
DMA using TM-0500 2333-30e
Decanoic Acid using TM-0622 - Rev # 1
Ketotifen Fumarate Assay using TM-0624_ASSAY_RC - Rev # 2
Refractive Index using TM-0589 - Day 8
Refractive Index using TM-0589 - Rev # 0 - Day 5

我需要输出如下：

    - Day 5                  TM-0589            Rev # 0

这是可能的，因为我似乎无法使其正常工作。我仍然需要找到提取analyze_method的方法，当我看到像CRM-0200这样的字符串：'Decanoic Acid CRM-0200'

这是我到目前为止所得到的：

select  distinct t.reported_name, 
       (case 
           when regexp_like(t.reported_name, '.* using (.*)([ ]?[-]?[ ]?Rev.*)') 
            then regexp_replace(t.reported_name, '.* using (.*)([ ]?- Rev.*)', '\1')
          when regexp_like(t.reported_name, '.* using (.*)') 
            then regexp_replace(t.reported_name, '.* using (.*)', '\1') 
          else '' end)  as analysis_method_regexp,

        (case when regexp_like(t.reported_name, '.*[ ]?[-]?[ ]?(Rev[ ]?#[ ]?[0-9]+).*') 
          then regexp_replace(t.reported_name, '.*[ ]?[-]?[ ]?(Rev[ ]?#[ ]?[0-9]+).*', '\1') 
          else '' end)  as revision_regexp
from test t;

Answer 1

以下是我解决问题的方法。首先描述每个输出列的搜索条件：
- 第1列是整行 - 如果该行中有“using”，则第二列是“using”后面的字符串。 - 如果该行中包含字符串“Rev＃”，则第3列为“Rev＃”加上其后的字符串。

然后使用正则表达式为匹配规则编写规则：

with sel as(
  --  Test data that matches all combinations.
  select 'TEGMA' str from dual
  union
  select 'Blue HEMA using TM-0510' str from dual
  union
  select 'Decanoic Acid using TM-0622 - Rev # 1' str from dual
  union
  select '% Ketotifen Released using TM-0578_V2_RELEASE' str from dual
  union
  select 'Leachable Polymer using CRM-0225 Sample B' str from dual
  union
  select 'Ketotifen Fumarate Assay using TM-0624_ASSAY_RC - Rev # 2' str from dual
)  
SELECT str reported_name,
       CASE
         -- if line contains " using " then...
         WHEN regexp_like(str, '.* using .*') THEN
           -- use groups. 1st group is the beginning of the line, ending with
           --   "...using ".  The second group starts right after the space after
           --   "using ", and matches any number of characters that are not a 
           --   space or the end of the line. Followed by any number of any
           --   characters that we do not care about.  
           --   Return the second group only.
           regexp_replace(str, '^(.* using )([^ $]*).*', '\2') 
       END analysis_method,
       CASE
         -- if line contains " Rev # (a number)" then..
         WHEN regexp_like(str, '.* Rev # \d.*') THEN
           regexp_replace(str, '(.* )(Rev # [^ $]).*', '\2') 
       END revision_number
from sel;

输出：
