Find queries executed in specific time range in Teradata database

Teradata enables you to check last query executed in specific time range

Notes

To log query information you need to create rules for logs. To do this use BEGIN QUERY LOGGING statement. You can find out how to use it in teradata documentation. Example statement to log all queries:

BEGIN QUERY LOGGING ON ALL;

        ErrorCode,
        ErrorText,
        TotalIOCount,
        NumResultRows
FROM    DBC.QryLogV
