Any Oracle Gurus on max function for alpha numeric (A-99) Revision

Any Oracle Experts ?

I'm struggling with a database extract of Windchill CAD Data with latest revision and iteration.
I've PL/SQL Procedure with max(version) which give wrong latest revisions due to revisions from A-99
Max(A-99) gives Z and Max(1-10) gives 9 as latest.

How to use to_number and to_char conditionally and use max function called in select statement of procedure.

regards

Venkata - A query like listed below would give you the latest version and iteration for Parts. It would be similar for CAD Documents as well. The key using the 'MAX(VERSIONSORTIDA2VERSIONINFO)'

SELECT m.wtpartnumber||'|'||m.name||'|'||p.statestate||'|'||p.VERSIONIDA2VERSIONINFO||'|'
FROM wtpart p, wtpartmaster m
WHERE p.ida3masterreference=m.ida2a2
AND p.VERSIONSORTIDA2VERSIONINFO =(SELECT MAX(VERSIONSORTIDA2VERSIONINFO) from wtpart WHERE ida3masterreference=m.ida2a2)
AND p.LATESTITERATIONINFO=1
AND STATECHECKOUTINFO <>'wrk';

Best Regards,

Windchill 9.1 M070
What I use to select the latest revision and iteration is this:
select * from
     (
         select ed.ida2a2, edm.cadname NAME, ed.statestate RELEASE,
             ed.versionida2versioninfo REVISION,
             ed.iterationida2iterationinfo ITERATION,
             cast(ed.createstampa2 as timestamp) "CREATED",
             cast(ed.modifystampa2 as timestamp) "MODIFIED",
             cast(ed.updatestampa2 as timestamp) "UPDATED",
             ed.ida3b10
         from
             epmdocumentmaster edm, epmdocument ed
         where
             edm.cadname = 'CadNameOfEPMObjectGoesHere'
             and ed.ida3masterreference = edm.ida2a2
             and ed.latestiterationinfo = 1
             and ed.statecheckoutinfo != 'wrk'
         order by "MODIFIED" desc
     )
where rownum=1;

Notice it is sorting by MODIFIED (epmdocument.modifystampa2) and then returning the 1st row of that selection. If your Windchill system is set up to allow checkin of earlier revisions then the above will not return the latest revision.iteration.

This is much simpler than the query I posted and also does not break if the Windchill system allows checkin of previous revisions.

We use this. Our revision starts at "-" then go to "A", "B", etc.. I assign an integer value to the revision and sort based on that.

SELECT
EPMDocumentMaster.CADName "CADName"
,EPMDocument.versionIdA2versionInfo "Revision"
,EPMDocument.iterationIdA2iterationInfo "Iteration"
,EPMDocument.statestate "State"
,PDMLinkProduct.namecontainerInfo "Product"
,SubFolder.name "Folder"
,CASE LEN(EPMDocument.versionIdA2versionInfo)
WHEN 1 THEN ASCII(EPMDocument.versionIdA2versionInfo) -64
WHEN 2 THEN ((ASCII(SUBSTRING(EPMDocument.versionIdA2versionInfo, 1, 1))-64)*26) + (ASCII(SUBSTRING(EPMDocument.versionIdA2versionInfo,2,1))-64)
END VersionLetterInt
FROM
EPMDocumentMaster
,EPMDocument
,PDMLinkProduct
,SubFolder
WHERE
EPMDocumentMaster.CADName = 'model_program_new.prt'
AND EPMDocument.idA3masterReference = EPMDocumentMaster.idA2A2
AND EPMDocument.idA3containerReference = PDMLinkProduct.idA2A2
AND EPMDocument.idA3B2folderingInfo = SubFolder.idA2A2
ORDER BY
VersionLetterInt ASC, Cast(EPMDocument.iterationIdA2iterationInfo AS INTEGER) ASC
