Question

我想提高查询的性能。由于使用了listagg和regxp_like，查询性能可能会降低。是否还有其他更好的选择来取代这两个可能改善性能的功能。

我不允许在表格中引入任何索引使用。（为所有表添加了更多索引......不能添加更多）
需要调整查询方法以提高其性能

Answer 1

通过SQL Tuning Advisor（如果获得许可）运行它。

此外，如果外部联接只是一个查找，您可以通过在选择列表中使用select语句来消除外部联接（这有时可以提高性能）。

Answer 2

When confronted with a multi-part query such as yours, I would study each part independently - and make use of explain plans as I go.

For example, in your original query, the first CTE contains this:

 SELECT
    S.NAME SUAS_SERVICE
  , S.SERVICEID SUAS_SERVICE_ID
  , SUB.NAME SUBSCRIBER_NAME
  , SMAUC.SERVICEID SMAUC_SERVICE_ID
  , SMAUC.NAME SMAUC_SERVICE
  , SIPVPN_MAIN.NAME SIPVPN_MAIN_SERVICE
  , SIPVPN_RED.NAME SIPVPN_RED_SERVICE
  , SIPSBV.NAME SIPSBV_MAIN
  , SIPSBV_RED.NAME SIPSBV_RED
 FROM SERVICE S
 INNER JOIN SUBSCRIBER SUB ON SUB.SUBSCRIBERID = S.SERVICE2SUBSCRIBER AND S.SERVICE2SERVICETYPE = 1955100016
 --Fetching SMAUC service
 LEFT JOIN SERVICEOBJECT SO1 ON SO1.SERVICEOBJECT2SERVICE = S.SERVICEID AND SO1.SERVICEOBJECT2RELATION = 1955100029
 LEFT JOIN SERVICE SMAUC ON SMAUC.SERVICEID = SO1.SERVICEOBJECT2OBJECT
 --Fetching SIPVPN MAIN service
 LEFT JOIN SERVICEOBJECT SO2 ON SO2.SERVICEOBJECT2SERVICE = S.SERVICEID AND SO2.SERVICEOBJECT2RELATION = 1955100023
 LEFT JOIN SERVICE SIPVPN_MAIN ON SIPVPN_MAIN.SERVICEID = SO2.SERVICEOBJECT2OBJECT
 --Fetching SIPVPN Redundant service
 LEFT JOIN SERVICEOBJECT SO3 ON SO3.SERVICEOBJECT2SERVICE = S.SERVICEID AND SO3.SERVICEOBJECT2RELATION = 1955100042
 LEFT JOIN SERVICE SIPVPN_RED ON SIPVPN_RED.SERVICEID = SO3.SERVICEOBJECT2OBJECT
 --Fetching SBV SIP Trunk IMS service
 LEFT JOIN SERVICEOBJECT SO4 ON SO4.SERVICEOBJECT2SERVICE = S.SERVICEID AND SO4.SERVICEOBJECT2RELATION = 1955100030
 LEFT JOIN SERVICE SIPSBV ON SIPSBV.SERVICEID = SO4.SERVICEOBJECT2OBJECT
 --Fetching Redundant SBV SIP Trunk IMS service
 LEFT JOIN SERVICEOBJECT SO5 ON SO5.SERVICEOBJECT2SERVICE = S.SERVICEID AND SO5.SERVICEOBJECT2RELATION = 1955100031
 LEFT JOIN SERVICE SIPSBV_RED ON SIPSBV_RED.SERVICEID = SO5.SERVICEOBJECT2OBJECT

Perhaps reducing the number of left joins will help?

SELECT
      S1.NAME SUAS_SERVICE
    , S1.SERVICEID SUAS_SERVICE_ID
    , SUB.NAME SUBSCRIBER_NAME
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100029 then s2.SERVICEID end, ',') SMAUC_SERVICE_ID
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100029 then s2.NAME end, ',') SMAUC_SERVICE
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100023 then s2.NAME end, ',') SIPVPN_MAIN_SERVICE
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100042 then s2.NAME end, ',') SIPVPN_RED_SERVICE
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100030 then s2.NAME end, ',') SIPSBV_MAIN
    , listagg(case when SO.SERVICEOBJECT2RELATION = 1955100031 then s2.NAME end, ',') SIPSBV_RED
FROM SERVICE S1 
INNER JOIN SUBSCRIBER SUB ON SUB.SUBSCRIBERID = S1.SERVICE2SUBSCRIBER 
LEFT JOIN SERVICEOBJECT SO ON SO.SERVICEOBJECT2SERVICE = S.SERVICEID
   AND SO.SERVICEOBJECT2RELATION IN (1955100029 , 1955100029, 1955100023, 1955100042, 1955100030, 1955100031)
LEFT JOIN SERVICE S2 ON SMAUC.SERVICEID = SO.SERVICEOBJECT2OBJECT
WHERE S1.SERVICE2SERVICETYPE = 1955100016
GROUP BY
      S1.NAME 
    , S1.SERVICEID 
    , SUB.NAME

Add the regexp_relace as needed.

Continue to the next CTE.

Answer 3

通过@ Used-By-Already给出的小提示，我可以在查询中做一些调整，它确实解决了我的问题。在我的查询中没有注意到一个重要的过滤器。
