Subj:   Re: Count of all rows, all tables
 
From:   Stover, Terry

Teradata does not store row counts in any system database tables (unless someone has come up with a way to deduce row count estimates from collected statistics). You have to set up a process to log row counts periodically. I find tracking row counts is more useful than space for managing growth since space changes depending on nusi's and compression. If you are trying to see who's taking up your space you can can get table size from dbc.tablesize.

     SELECT t.databasename, t.tablename, t.creatorname, t.createtimestamp,
            t.lastaltertimestamp, sum(ts.currentperm) currentperm

     FROM dbc.tables t, dbc.tablesize ts

     WHERE t.databasename = ts.databasename
       and t.tablename = ts.tablename
       and t.tablekind = 'T'
       and t.databasename = 'dw_data'

     GROUP BY 1,2,3,4,5
