This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Ok, I have to write an Oracle trigger in which I need to do a Select on the table a new record is being added to. I need to get the max value of a column and compare it with the value for that column for the new record.
But running it gives a table mutating error, which makes sense because you are trying to get a value from the table that is being modified at that point. Of course I could move the logic out to the Java class, but in what other way can it be done in the database?
