Undo changes to SQL database? Well, sort of….

Monday, May 24th, 2010

Not too far back, a client who spends all day (and sometimes all night) creating and running SQL queries and commands in a secure database posed an interesting question:  When working late at night, he’s concerned that he will accidentally botch a SQL command and cause irreparable harm to the database – is there such a thing as an undo button in SQL?


Sorry, the short answer is no, there is no CTRL + Z keystroke equivalent that will magically undo a potentially disastrous command once committed to the database, and most query tools run in autocommit mode.  If you find this post during a panic-induced hunt for options to repair error(s) you realize you made a few hours ago, your options are few and far between:


  • You can restore all or part of the database from a backup (you do have a backup, don’t you?), which is the start of a whole new problem that possibly now involves your boss
  • You can rollback transactions, assuming they haven’t been committed
  • You can rollback to a given point in time using a savepoint name


Randomly undoing transactions in a SQL database can leave it in an inconsistent state.  It is therefore not only advisable but necessary to examine each operation relationally prior to altering database structure.  Transaction logs contain changes only, and it can be difficult to piece together the relationship of individual changes to the big picture.  Third-part software such as this SQL transaction log tool can assist in this regard by providing an operation-by-operation breakdown of each change to give you greater perspective.  This SQL Server transaction log restore tutorial may assist you in the event you’re forced to restore prior versions of database or file groups, as well as points in time.


Another tip when working on something extremely sensitive (or late at night when normal people are sleeping) is to disable autocommit using set implicit_transactions {ON/OFF}, which will give you the option to rollback or commit manually.  The setting is also available in Microsoft SQL Query Analyzer under TOOLS>OPTIONS>CONNECTION PROPERTIES.


Of course, you could go to bed at a decent hour instead of executing SQL commands after midnight like some kind of crazy nocturnal code monkey.  Or just be more careful, whatever works for you….

Office 2010: New Quick Steps feature in Microsoft Outlook

Wednesday, May 12th, 2010


Microsoft Office 2010 drops in early summer 2010, but the beta is publicly available at the time of this posting for those interested in playing with it.  A pretty cool feature in Microsoft Outlook is the new Quick Steps option for customizing the e-mail management toolbar and saving time – and it’s configurable with minimal hassle.


If your mornings are anything like mine, you spend the first half hour of your day in Outlook, poring through e-mail reports on network health, server and SQL backups, and other scintillating A.M. reading apparently designed for the sole purpose of putting you back to sleep.  Once reading is completed, these e-mails have to be filed in the appropriate client folder, forwarded to the relevant person or department, or replied to and deleted like the junk they are.  These options can now appear all in one place to assist you in keeping things organized and streamlining the disposition of mass amounts of e-mail while you still have sleep in your eyes.

Scareware and rogue antivirus infections reach epidemic proportions

Friday, May 7th, 2010

Every week it’s the same complaint:  I got a pop-up saying my PC was infected, so I clicked on the link to remove the infection – and now the pop-ups won’t stop, my browser is hijacked, and I can’t reach any site but the one prompting me for my credit card information!


The fake antivirus, or “scareware,” trend that began several years ago was apparently not publicized sufficiently, because it continues to affect an alarming number of novice web surfers.  Preying on the uninitiated and the careless internet user alike, these malware are generating unprecedented sums of money for their creators as they steal credit card, bank account, social security, and other personal information, in addition to the money literally handed to them by those who are frightened enough to actually enter their credit card number.



fake antivirus software

Just because it walks like a duck and quacks like a duck doesn't always mean it's a duck...



In addition, many people expect that their anti-virus program will stop this type of thing – and that is a reasonable expectation.  However, many anti-virus companies such as McAfee, Norton Antivirus, and AVG have different programs to provide different levels of protection.   For instance, if you use the free edition of AVG software, which is a great antivirus program, it will not be able to stop “scareware.”   So when choosing protection software, reading and understanding the fine print is important!


Another issue is that the rate of these attacks, compared to other types of online attacks, is growing exponentially.  It’s very hard for the makers of security software to keep up with the constantly escalating exploitation of operating system and software vulnerabilities; therefore, some users may be exposed for a time while antivirus companies try to catch up.  What can you do?  Here are few common sense tips for the novice that will help prevent infection from fake antivirus and malware in general:

  • Don’t open e-mail attachments if you are unsure of the sender’s identity
  • Don’t haphazardly click on every link presented to you while surfing (this is how the majority of viruses are contracted)
  • Keep operating systems and software updated to preempt exploitation of vulnerabilities
  • Some pop-ups discuss the “X” to close the window as something malicious.  Learn to use the keystrokes “Alt-F4” if you are on a Microsoft Windows-based computer to close the window instead
  • Use Google to identify unrecognized software running on your computer
  • Once you think your PC is infected, disconnect it from the internet and don’t use it until the virus has been removed
  • Contact Gyver Networks

Of course, Gyver Networks can assist you after an attack, but our first choice is to provide you with protection  before something catastrophic happens.  We do this by educating our clients in the dangers lurking just on the other side of their firewall, and by implementing the optimal network and PC security software for their environment.
