Cognos 8 Query查找所有报告和列名称

Question

I want to query the meta data in Cognos 8 to find all report and column names. If possible, I'd like to include the column definitions.

Can I do this using a Cognos report or do I need to query some repository?

Thanks.

You can select a list of reports from the content store with the following query:

SELECT     CMOBJNAMES_BASE.NAME AS ObjName, CMOBJECTS.PCMID, CMCLASSES.NAME AS ClassName, CMOBJPROPS7.spec
FROM       CMOBJECTS 
JOIN       CMOBJNAMES_BASE ON CMOBJECTS.CMID    = CMOBJNAMES_BASE.CMID
JOIN       CMCLASSES       ON CMOBJECTS.CLASSID = CMCLASSES.CLASSID
LEFT JOIN  CMOBJPROPS7     ON CMOBJECTS.CMID = CMOBJPROPS7.CMID
WHERE     CMOBJECTS.CLASSID IN (10, 37)
ORDER BY CMOBJECTS.PCMID;

I use that in Cognos 10. I believe in cognos 8 the CMOBJNAMES_BASE table is actually named 'CMOBJNAMES' without the _BASE.

The Report metadata is stored in the 'SPEC' column of CMOBJPROPS7 as XML. You can parse this XML in order to strip out the columns used in the report. It will not be a simple task.

If you have time but not money, you can write your own code to parse that XML. If you have more money than time, you can buy a 3rd party program to accomplish this, such as Motio or BSP Metamanager.

The query above is less useful for building a clean list of columns, but great for searching for specific data items. For example, you have column you are wanting to change in a data source, but you are not sure which report uses that column. Run the query above, and search for the data item. It will be embedded within the XML in the Cognos MDX format, ie. [Presentation View].[Sales Summary].[Sales]

EDIT: As requested below, here is a query that includes folder paths.

-- List of Reports, the folder they are in, and the package they are using
select distinct temp2.name as package,temp1.folder,temp1.name from
(SELECT    temp.PARENTNAME AS FOLDER,CMOBJECTS.PCMID,CMOBJNAMES.CMID, CMOBJNAMES.LOCALEID, CMOBJNAMES.MAPDLOCALEID, CMOBJNAMES.ISDEFAULT, CMOBJNAMES.NAME, 
                      CMOBJECTS.CLASSID
FROM         CMOBJNAMES INNER JOIN
                      CMOBJECTS ON CMOBJNAMES.CMID = CMOBJECTS.CMID
INNER JOIN
(SELECT P.CMID AS PARENT,P.NAME AS PARENTNAME FROM CMOBJNAMES P where P.LOCALEID between 24 and 52) temp
ON CMOBJECTS.PCMID = TEMP.PARENT
WHERE     (CMOBJECTS.CLASSID = 10)
AND SUBSTR(TEMP.PARENTNAME,1,1) NOT IN ('1','2','3','4','5','6','7','8','9') AND
TEMP.PARENTNAME NOT LIKE 'Backup%') temp1
inner join
(SELECT  CMREFNOORD1.CMID AS PID, CMREFNOORD1.REFCMID, CMOBJNAMES.NAME
FROM         CMREFNOORD1 INNER JOIN
                      CMOBJECTS ON CMREFNOORD1.REFCMID = CMOBJECTS.CMID INNER JOIN
                      CMOBJNAMES ON CMOBJECTS.CMID = CMOBJNAMES.CMID
WHERE     (CMREFNOORD1.PROPID = 31 AND CMOBJNAMES.LOCALEID between 24 and 52)) temp2
on temp1.cmid = temp2.pid and LOCALEID between 24 and 52;

Answer 2

Not sure if this will help anybody, but our version doesn't have a table named CMOBJNAMES_BASE.

This is what works for me:

select ob2.cmid, c.name as classname, n.name as objectname, o.DELIVOPTIONS as deliveryoptions, z2.name as owner
from CMOBJPROPS2 p
inner join CMOBJPROPS26 o on p.cmid=o.cmid
inner join CMOBJECTS ob on ob.cmid=o.cmid
inner join CMOBJECTS ob2 on ob.pcmid=ob2.cmid
inner join CMOBJNAMES n on n.cmid=ob2.cmid
inner join CMCLASSES c on ob2.classid=c.classid
left join CMREFNOORD2 z1 on z1.cmid = p.cmid
left join CMOBJPROPS33 z2 on z2.CMID = z1.REFCMID
where ACTIVE = 1 order by z2.name, objectName
