FYI,

In dbc.statsv, LastCollectTimestamp is the last time statistics were updated for the column LastAlterTimeStamp is the last time a collect statistics has been submitted for this column/columns StatsSkipCount is a count of the number of times that an collect statistics has been executed, but Teradata decided the stats did not need to be collected due to Thresholds. It resets to 0 when stats are updated.

Run a command like the following to see exactly see all the exact stats statements that were collected. This shows thresholds and MaxValueLength.

     SHOW STATISTICS ON databasename.tablename;

You might want to look at using Viewpoint Portal Stats Manger to maintain stats.

Thanks,

Bob
