You can use the Teradata SQL DELETE statement to clear outdated log data, for example, DBC.LogOnOffV log data.

The user running the SQL statement must have the DELETE privilege on the corresponding view.

For example:

You can clear DBC.LogOnOffV log data based on age. Teradata recommends retaining 90 days of log data and purging directly from the DBC.EventLog table.

DELETE FROM DBC.EventLog
WHERE (DATE-DateFld) > 90;

You can clear information for an account after a cost accounting period has closed.

DELETE FROM DBC.AMPUsageV
   WHERE Accountname = '$M619';
