将数据分成多列

Question

表中的第一行：

1A:CAD22021828,17:1B:RECEIVE GENERAL IND11 BEGUM ST:1C: C/O PNBB MAIN BRANCH 11 BEGUM ST 3-15A2:

表中的第二行：

:1A:/002429389016 CITY OF NAGAL AP IN 392H 329 :1E://NAGOLE STREET NAGAL AP :2A:/154510002 OFD DEPOSITORY LTD :

现在我希望将此数据加载到另一个表中，如下所示：

第一行：

1A  CAD22021828,17  
1B  RECEIVE GENERAL IND 11 BEGUM ST /000061071257
1C  C/O PNBB MAIN BRANCH 11 BEGUM ST 3-15A2

第二行：

1A  /002429389016 CITY OF NAGAL AP IN 392H 329
1E  //NAGOLE STREET NAGAL AO
2A  /154510002 OFD DEPOSITORY LTD

我已经尝试过REGEXP_SUBSTR

SELECT
 REGEXP_SUBSTR(mc_clob,':1A:([[:alnum:]]+\S+)') AS code1A,
 REGEXP_SUBSTR(mc_clob,':1B:([[:alnum:]]+\s+)') AS code1B,
 REGEXP_SUBSTR(mc_clob,':1C:([[:alnum:]]+\s+)') AS code1c
FROM tableA;

第一行：

1A  CAD22021828,17  
1B  RECEIVE GENERAL IND 11 BEGUM ST /000061071257
1C  C/O PNBB MAIN BRANCH 11 BEGUM ST 3-15A2

第二行：

1A  /002429389016 CITY OF NAGAL AP IN 392H 329
1E  //NAGOLE STREET NAGAL AO
2A  /154510002 OFD DEPOSITORY LTD

Answer 1

这是一般问题how do i split delimited values的特例

尝试一下。我假设您在tableA中有一些键-在这里我称之为“ id”。如果此表中没有唯一键，请告诉我，我将其重写为使用rowid。

-- sample data
with tablea as (select 1 as id, ':1A:CAD22021828,17:1B:RECEIVE GENERAL IND11 BEGUM ST:1C:     C/O PNBB MAIN BRANCH 11 BEGUM ST 3-15A2:' as mc_clob from dual
           union select 2 as id, ':1A:/002429389016 CITY OF NAGAL AP IN 392H 329 :1E://NAGOLE STREET NAGAL AP :2A:/154510002 OFD DEPOSITORY LTD :' from dual)
-- query
SELECT id, 
 regexp_substr(mc_clob, '[^:]+', 1, level*2-1) as code,
 trim(regexp_substr(mc_clob, '[^:]+', 1, level*2)) as val
FROM tableA
connect by regexp_substr(mc_clob, '[^:]+', 1, level*2) is not null
      and PRIOR id =  id 
      and PRIOR SYS_GUID() is not null;

输出：

ID  CODE VALUE
1   1A   CAD22021828,17
1   1B   RECEIVE GENERAL IND11 BEGUM ST
1   1C   C/O PNBB MAIN BRANCH 11 BEGUM ST 3-15A2
2   1A   /002429389016 CITY OF NAGAL AP IN 392H 329
2   1E   //NAGOLE STREET NAGAL AP
2   2A   /154510002 OFD DEPOSITORY LTD

如果您的字段中有空白数据，此查询将无法很好地处理它。但也许会有所帮助。
