将来自 SP 的有效记录插入有效 table 并将无效记录插入无效 SP

Question

我有两个存储过程，它们过滤table上的记录并给出结果。下面是存储过程。

SELECT distinct  TO_CHAR(sp.RJ_SPAN_ID) AS SPAN_ID
               , TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE) AS MAINT_ZONE_CODE
from  APP_FTTX.span@SAT sp
INNER JOIN APP_FTTX.transmedia@SAT tm  -- transmedia added
on sp.RJ_SPAN_ID = tm.RJ_SPAN_ID
WHERE length(sp.RJ_SPAN_ID) = length(tm.RJ_SPAN_ID)
and sp.RJ_MAINTENANCE_ZONE_CODE = tm.RJ_MAINTENANCE_ZONE_CODE
and sp.INVENTORY_STATUS_CODE = tm.INVENTORY_STATUS_CODE
AND LENGTH(sp.RJ_SPAN_ID) = 21
AND (sp.RJ_SPAN_ID LIKE ('%SPN%') 
     OR sp.RJ_SPAN_ID LIKE ('%SPQ%') 
     OR sp.RJ_SPAN_ID LIKE ('%SPR%')    
     OR sp.RJ_SPAN_ID LIKE ('%SPS%'))
AND (sp.RJ_SPAN_ID LIKE ('%_BU') 
     OR sp.RJ_SPAN_ID LIKE ('%_MP'))
AND sp.INVENTORY_STATUS_CODE = 'IPL'
AND sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01'
AND (sp.RJ_INTRACITY_LINK_ID NOT LIKE ('%\_9%') ESCAPE '\' 
     OR sp.RJ_INTRACITY_LINK_ID IS NULL);

上面的 SP returns 4 条记录，这些是我要插入到 table 中的有效记录。

现在又多了一个SP，下面有returns 7条记录。

SELECT distinct  TO_CHAR(sp.RJ_SPAN_ID) AS SPAN_ID
               , TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE) AS MAINT_ZONE_CODE
from  APP_FTTX.span@SAT sp
-- INNER JOIN APP_FTTX.transmedia@SAT tm  -- transmedia added
--  on sp.RJ_SPAN_ID = tm.RJ_SPAN_ID
-- WHERE length(sp.RJ_SPAN_ID) = length(tm.RJ_SPAN_ID)
--  and sp.RJ_MAINTENANCE_ZONE_CODE = tm.RJ_MAINTENANCE_ZONE_CODE
--   and sp.INVENTORY_STATUS_CODE = tm.INVENTORY_STATUS_CODE
WHERE LENGTH(sp.RJ_SPAN_ID) = 21
AND (sp.RJ_SPAN_ID LIKE ('%SPN%') 
     OR sp.RJ_SPAN_ID LIKE ('%SPQ%') 
     OR sp.RJ_SPAN_ID LIKE ('%SPR%')    
     OR sp.RJ_SPAN_ID LIKE ('%SPS%'))
AND (sp.RJ_SPAN_ID LIKE ('%_BU') 
     OR sp.RJ_SPAN_ID LIKE ('%_MP'))
AND sp.INVENTORY_STATUS_CODE = 'IPL'
AND sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01'
AND (sp.RJ_INTRACITY_LINK_ID NOT LIKE ('%\_9%') ESCAPE '\' 
     OR sp.RJ_INTRACITY_LINK_ID IS NULL);

SP 是相似的。第二个 SP 中有 3 条记录无效。所以我想要的是：我想将其他 3 条无效记录插入另一个 table.

请建议如何实现。

根据 Alex 的评论，我已经在下面的代码中实现了减号部分。

SELECT distinct  TO_CHAR(sp.RJ_SPAN_ID) AS SPAN_ID, TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE) AS MAINT_ZONE_CODE

我认为你最好做一个 LEFT JOIN。

SELECT DISTINCT sp.RJ_SPAN_ID AS SPAN_ID,
                sp.RJ_MAINTENANCE_ZONE_CODE AS MAINT_ZONE_CODE,
                SYSDATE AS MSG_DATE
FROM   APP_FTTX.span@SAT sp
WHERE  LENGTH(sp.RJ_SPAN_ID) = 21
AND REGEXP_LIKE(sp.rj_span_id, 'SP(N|Q|R|S).*_(BU|MP)$')
AND sp.INVENTORY_STATUS_CODE = 'IPL'
AND sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01'
AND NVL(INSTR(sp.RJ_INTRACITY_LINK_ID, '_'), 1) > 0
AND NOT EXISTS (SELECT 'X'
                FROM APP_FTTX.transmedia@SAT tm
                WHERE tm.rj_span_id = sp.rj_span_id
                AND tm.rj_maintenance_zone_code = sp.rj_maintenance_zone_code
                AND tm.inventory_status_code = sp.inventory_status_code);

注意 NULL 检查 tm.rj_span_id。考虑到我们的其他逻辑，应该保证填充该列。由于是 NULL，我们知道未找到匹配项。

我还做了一些其他调整：

在底部做length(sp.RJ_SPAN_ID) = length(tm.RJ_SPAN_ID)没有用。您已经检查过 JOIN 期间的值是否相等。如果它们的值相等，则长度必须相同。
考虑使用 REGEXP_LIKE 来简化您的逻辑。像 REGEXP_LIKE(sp.rj_span_id, 'SP(N|Q|R|S).*_(BU|MP)$')
删除了列列表中的 TO_CHAR。正如评论中所讨论的，它们已经是字符串。
我将你的 NOT LIKE 和 IS NULL 更改为使用 NVL 和 INSTR，但这更符合我的偏好（我一直在玩 Code Golf 它影响了我的大脑）

至于您的 INSERT，只需将 SELECT 附加到 INSERT INTO table_name 即可。像这样：

INSERT INTO log_table_name
  SELECT DISTINCT sp.RJ_SPAN_ID AS SPAN_ID,
                  sp.RJ_MAINTENANCE_ZONE_CODE AS MAINT_ZONE_CODE,
                  SYSDATE AS UPDATED_DATE,
                  'YOUR_USERNAME' AS USERNAME
  FROM   APP_FTTX.span@SAT sp
  WHERE  LENGTH(sp.RJ_SPAN_ID) = 21
  AND REGEXP_LIKE(sp.rj_span_id, 'SP(N|Q|R|S).*_(BU|MP)$')
  AND sp.INVENTORY_STATUS_CODE = 'IPL'
  AND sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01'
  AND NVL(INSTR(sp.RJ_INTRACITY_LINK_ID, '_'), 1) > 0
  AND NOT EXISTS (SELECT 'X'
                  FROM APP_FTTX.transmedia@SAT tm
                  WHERE tm.rj_span_id = sp.rj_span_id
                  AND tm.rj_maintenance_zone_code = sp.rj_maintenance_zone_code
                  AND tm.inventory_status_code = sp.inventory_status_code);

注意：我对 UPDATED_BY 列进行了硬编码，因为我不知道正确的值。
