Access Logging Question

Hello,

I have turned Access Loging on for some of our databases. Using Teradata Administrator to do this, I saw some options I am not really sure what they are for, and hoped someone here could explain them to me.

The options are:

First
Last
First & Last
Each

Can someone explain these Access Logging options to me please? I have been unable to find them defined in any manual.

Thanks!

Paul

Re: Access Logging Question

Access Logging options are documented in the SQL Reference: SQL Data Definition Language (Syntax & Examples) manual.

 

First - inserts a row the first time the indicated permissions are checked for a session (optionally, only if denied)

Each - inserts a new row every time

Last - must do "update if matching log row exists else insert" (because there is no way to know in advance which request will be last)
