And I think it's going on right now. In April, Christian Rokitta blogged about Categorizr.
He adapted some PHP code from Brett Jankord and suited it to PL/SQL.
When I was building the mobile application for my AUSOUG presentation, I found it useful for statistics gathering... but I wanted more.
I added a few more functions, and included an object type to allow queries shown further below.
These functions broke/butchered the agent string further into
- OS
- OS Version
- Browser
- Browser version
CREATE TYPE categorizr_agent_details IS OBJECT (
agent VARCHAR2 (2000)
,device VARCHAR2 (2000)
,os VARCHAR2 (2000)
,os_version VARCHAR2 (2000)
,browser VARCHAR2 (2000)
,browser_version VARCHAR2 (2000)
);

If you were to utilise this package for production code, I would first check it for defects - then question your need to set the user agent in the package body.
I might also suggest that as this code matures, it could be added to the Alexandra PL/SQL Library, administered by Morten, expanded/updated by the masses, encouraging other utilities to come visiting.
Let me know if you find it handy or have any feedback. Thank you Christian & Brett for the boost.

Hi Scott,
I like your extension of my package.
I actually was working on a similar functionality, as you can see on my Categorizer package demo page. It get's more detailed information from the user agent string.
The problem with this kind of "browser sniffing" is, one has to maintain the code with new browser versions or brands.
Cheers,
Christian
Thanks Christian - I think I saw the hint of what you were doing when I was writing up the post, but failed to mention it - sorry!
Yeah, I was wondering that when I was reading your post about Brett's work - wondering the mechanism - it would certainly need to grow over time.
But for what use? There are other methods to determine the size of the page and responsive design helps style page design.
I thought the it provided interesting statistics - I would hate to code for different browsers in this day & age. IE is behind, but consumers should force demand!
I wonder how Google Analytics provides their OS/browser statistics - do they just feed the same input into their own mincer?
Ooh an interesting world.
Scott,
This is just amazing ... exactly I was prepared to make from the scratch. But this is now not needed....thank you very much-respect!

JUst to make small hint for easy readiness:
FUNCTION isdesktop
RETURN BOOLEAN
IS
BEGIN
return nvl(g_agent_details.device,'?') = 'desktop'
END;
-- Returns true if tablet user agent is detected
FUNCTION istablet
RETURN BOOLEAN
IS
BEGIN
return nvl(g_agent_details.device,'?') = 'tablet'
END;
-- Returns true if SmartTV user agent is detected
FUNCTION istv
RETURN BOOLEAN
IS
BEGIN
return nvl(g_agent_details.device,'?') = 'tv'
END;
-- Returns true if mobile user agent is detected
FUNCTION ismobile
RETURN BOOLEAN
IS
BEGIN
return nvl(g_agent_details.device,'?') = 'mobile'
END;
I agree, I was just following the existing style - not trying to refactor too much. Thanks
