    After DBCC DBReindex ('ChgAttrHistoryHistoryDetails') , dbcc updateusage and sp_updatestats DBCC Showcontig still says extendfragmentation 50% for the clustering index ??

    Should I be worried ?

    DBCC SHOWCONTIG  ( 1772637458      )  WITH   TABLERESULTS , ALL_INDEXES

     go

     [ChgAttrHistoryId] [char] (16) NOT NULL ,

    you didn't specify the FILLFACTOR option while you do the DBCC DBREINDEX; so, may be, it takes the last fillfactor used and it can be 50 percent...

    thanks for the reply.

    fillfactor is default

    (sql2k sp3a)

    avgFreebytes = 38

    I guess having near 100% pagedensity and near 100% ScanDensity the extendfrag maybe does not matter.
