Question

I making a report in EM and I need to figure out somthing here

I have this query that I made:

SELECT
*
FROM
(
    SELECT DISTINCT
    patch.host as "PHost",
    patch.home_location as "PDirectory",
    patch.home_name as "PHome",
    MAX(patch.INSTALLATION_TIME) as "Patched (Date)",
    MAX(patch.PATCH_RELEASE) as "PVersion",
    listagg(patch,',') WITHIN GROUP (ORDER BY patch) "Patches"
    FROM
    mgmt$applied_patches patch
    GROUP BY patch.host, patch.home_location,patch.home_name
    ORDER BY patch.host, patch.home_location
) "PCH",
(
    SELECT DISTINCT 
    T1.PROPERTY_VALUE as "MHost",
    T2.PROPERTY_VALUE as "MDirectory",
    T3.PROPERTY_VALUE as "MVersion",
    count(T4.PROPERTY_VALUE) as "Count of SID",
    listagg(T4.PROPERTY_VALUE,',') WITHIN GROUP (ORDER BY T4.PROPERTY_VALUE) as "SID"
    FROM
    MGMT$TARGET_PROPERTIES T1,
    MGMT$TARGET_PROPERTIES T2,
    MGMT$TARGET_PROPERTIES T3,
    MGMT$TARGET_PROPERTIES T4
    WHERE
    T1.TARGET_GUID = T2.TARGET_GUID
    and T1.TARGET_GUID = T3.TARGET_GUID
    and T1.TARGET_GUID = T4.TARGET_GUID
    and T1.PROPERTY_NAME = 'MachineName'
    and T2.PROPERTY_NAME = 'OracleHome'
    and T3.PROPERTY_NAME = 'Version'
    and T4.PROPERTY_NAME = 'SID'
    GROUP BY T1.PROPERTY_VALUE, T2.PROPERTY_VALUE, T3.PROPERTY_VALUE
) "MGM"
WHERE
PDirectory = MDirectory

I’m getting error ORA-00904: “MDIRECTORY”:….

I tried many combinations! (PCH.PDirectory = MGM.MDirectory, ……) nothing works

cheers

Well…

This doesn’t work:

SELECT * FROM
(SELECT DUMMY AS  "PDirectory" FROM DUAL) "PCH",
(SELECT DUMMY AS  "MDirectory" FROM DUAL) "MGR"
WHERE PDIRECTORY = MDIRECTORY

But this works:

SELECT * FROM
(SELECT DUMMY AS  "PDirectory" FROM DUAL) "PCH",
(SELECT DUMMY AS  "MDirectory" FROM DUAL) "MGR"
where "PCH"."PDirectory" = "MGR"."MDirectory"

change your query accordingly.
