I was wondering if it was possible to do the following -

I would like to set a 'sync point' where

1) transactions could occur on a given database or databases after the
sync point was created in multiple sessions.
2) I could globally 'roll back' the database to the sync point.

I'm not thinking of the transaction begin/commit/rollback cycle, I'm
thinking of it truly globally - where users could do multiple commits
and rollbacks, and then do a global rollback to a given point of time.

In oracle, I believe this is done through transaction logs; how do you
set up this in sybase?

Ed

(ps - how do you get the version of sybase that you are running
against via isql? I see in my case the binary is old (1999) but I'm
assuming that the database itself is a lot newer..)

running much slower then other platforms. *much* slower. A bcp on the
Niagara platform seems to take twice as long as an older Sparc CPU.

I'm using Sybase 12.5 and Solaris 10.

Is there a way to determine which stored proc / SQL ran on a given day
in Sybase?
Does Sybase maintain a log which have these information?

Thanks in advance,
Subind.

We will update database on our office to version 15 very soon, but I
have some doubts about, maybe you could help me on that.
We have export/import procedures between many databases in our system,
some of them are customer side. Then this databases won't be upgraded.
The doubt is about these exp/imp procedures because for that we use
BCP in/out. I wanna know if bcp has problems between different
versions of sybase server.

Any help is welcome.
Tks

Indeed, mapping
technology is used everywhere and can be accessed easily online, from
a phone, and on the road. But can these applications be used
successfully in a business information and reporting context? The
short answer is yes.
Although it is early days, the marriage between location and business
intelligence software is being seen by many commentators as a highly
productive long-term relationship, rather than just a temporary
fling.

What is location intelligence?
Traditionally, businesses can spend days, or even weeks physically
compiling data from customer surveys and site visits. Location
intelligence software can drastically reduce this process by mapping
data electronically, thereby freeing up time for other activities.

How does it do this?

Basically, by using common data sources, such as GIS, aerial maps and
even customer records, location intelligence technology can present
data spatially – such as an interactive map format. This is much
easier for our brains to process than traditional charts and tables.
For example, by clicking on a map, managers can quickly gain an
insight into any number of location-based business operations.
There are obvious benefits to this technology, such as tightening up
business processes, improving customer relationships and even boosting
performance and results.

Who uses it?
The applications are endless:
• telecommunications organisations use it for network planning and
design and market analysis;
• Government uses it for many purposes, including census updates,
urban planning, weather forecasting and emergency services;
• retailers use it for site selection, store performance analysis and
demographic research; and
• media organisations use it for target market identification, media
planning and demographic analysis.

But until recently, using this technology as part of a business
reporting process has mostly been the preserve of experts. This is
because it has operated on a stand-alone basis, rather as part of an
organisation’s business intelligence platform. By converging the two
technologies, a whole new level of data analysis can become available
to the everyday user.
Yellowfin and location intelligence

The team at Yellowfin has acknowledged the popularity of location
intelligence as a business reporting tool by incorporating the
technology in its latest release, Yellowfin 4.0. This means
organisations can now introduce location-based reporting into the
business-decision making process without requiring GIS expertise.

Yellowfin 4.0 enables a variety of mapping visualisations to be used,
including Google Maps, Heat Maps or fully-enabled GIS data-type
rendering.

Of this latest trend in BI software, CEO Glen Rabie says: “With
Yellowfin 4.0, we have taken two mature technologies (BI and GIS) and
combined them. One of the most exciting aspects of our latest software
is that even the casual business user can use this technology. This is
one of the underlying principles of our Yellowfin products.”

This month's quiz question is about a recent virus performing
a SQL injection attack, and how Sybase databases may be
affected by this...
http://www.sypron.nl/quiz

The list of changes to the MDA tables has been updated to
include 15.0.2 esd#5:
http://www.sypron.nl/mda


As you've probably noticed, the second edition of "The Complete
Sybase Replication Server Quick Reference Guide" (also known
as the 'green book') was finally released last month.
This edition includes the just-released RS 15.1 version, and
has grown by 26 pages from the previous edition to 146 pages of
highly relevant tips and documentation that every RepServer
DBA, well, just needs to have.
Check out the table of contents, and order your copy, here:
http://www.sypron.nl/repqr

My other two ASE books are also still available here:

- The 4th edition of the well-known 'purple book' "The Complete
Sybase ASE Quick Reference Guide" is updated for ASE 12.5.4
and 15.0.1:
http://www.sypron.nl/qr

- The 2nd edition of "Tips, Tricks & Recipes for Sybase ASE" has
been updated for ASE 15.0 and is a must-have when you're upgrading to ASE
15.
The 2nd edition is fully updated and has 80 pages of additional material
compared with the first edition:

I have you tried:

WHERE datediff(dd,timestamp,'2008-06-04') = 0

??

Yes, specify a date range e.g. for today

where
timestamp>=dateadd(dd,datediff(dd,'20000101',getdate()),'20000101')
and timestamp+1,'20000101')
