Subj:   Re: Statistics about table statistics
 
From:   Tobianna Zappe

Ruth,

Here is an SQL that was written by Frank Slovac from NCR to help me answer the same question that you have:

     sel
     c.databasenamei as DatabaseName,
     b.tvmnamei as TableName,
     a.fieldname as ColumnName,
     cast((case when substr(fieldstatistics,1,1) = 'D2'XB
                then '2002-'
                when substr(fieldstatistics,1,1) = 'D1'XB
                then '2001-'
                when substr(fieldstatistics,1,1) = 'D0'XB
                then '2000-'
                when substr(fieldstatistics,1,1) = 'CF'XB
                then '1999-'
                when substr(fieldstatistics,1,1) = 'CE'XB
                then '1998-'
                else NULL
     end)||
     (case when substr(fieldstatistics,3,1) = '01'XB
                then '01-'
                when substr(fieldstatistics,3,1) = '02'XB
                then '02-'

     ('AFFINITY','CLAIMS_ECOMM','CLICKSTREAM','PCDW_AURORA','PCDW_AUTO'
     ,'PCDW_AUTOCS','PCDW_AUTOQB',

     'PCDW_CBR','PCDW_CLAIMS','PCDW_DSS','PCDW_ICAR','PRODUCERS','WEB_TEST')

     and a. fieldstatistics is not null
     order by 1,2,3
     ;

NOTE: This will check for fieldstatistics. You can also check indexstatistics by changing the column.


Hope this is what you were looking for!
