Summary0004925: oxutilscount::setCatArticleCount uses ugly sql statement (filesort, temp tables)
Descriptionoxutilscount::setCatArticleCount builds a sql query like

SELECT count(*) FROM (
                   SELECT count(*) FROM
[...]
GROUP BY oxv_oxarticles_4_de.oxid
                   ) AS ox2cat

Which does unneccessary operations in database (creating temporary tables, doing filesort).
Steps To Reproduce1) insert echo $sQ in oxutilscount::setCatArticleCount
2) delete aLocalCatCache-File from tmp and open Shop
3) take query and do "EXPLAIN {QUERY}" in Database

delete "SELECT count(*) FROM (" and ") AS ox2cat" from start and ending of query, change "SELECT count(*)" to "SELECT count(DISTINCT oxv_oxarticles_4_de.oxid) as cnt FROM" (replace my VIEWNAME.OXID through part that was in GROUP BY before).

Now again make EXPLAIN - no temporary tables will be opened.
Additional InformationAnother question regarding this -> how is an update request (invalidating) done in environments with more than one app-server?

Can be reproduced in 4.5.1 too
