Hello,

I have observed truncate statement (command_type = 85) doesn't appear in V$SQL. However, it does in V$SQLTEXT and V$SQLTEXT_WITH_NEWLINES.

My intention is to extract the time of the truncate statement. How can I achieve this task without going through ALL_TAB_MODIFICATIONS?

For other command_types (like Insert, Update, Delete, Select, Create), I can get the transaction time using LAST_ACTIVE_TIME in V$SQL

Thanks,

I don't you'll get it from the dynamic views.

Easy way to track it (and to make sure you *always* see it) would be to audit it

SQL> audit table;

Audit succeeded.

SQL> truncate table t;

Table truncated.

SQL> select * from dba_audit_trail
