• MySQL- complex data query in a single statement

  - by yoda

Now, imagine that you need to get all the roles related to an user, wich may be through it's related groups or directly related to him. In case the same role appears related to a group and the user directly, the role related to the user will prevail over the role given by the group.

• Response, Result, Reply, which is best?

  - by Robert Gould

  I'm refactoring some client-server code and it uses the terms Response, Result & Reply for the same thing (an answer from the server). And although its not really that important it's become hard to guess which word to use while writing new code, so I'd like to unify the three terms into one and do the appropriate refactoring, but I'm not sure which word is the "best", if there is such a thing. Any suggestions based on precedence and standards towards naming for this case?

• How to capture the event if a new process (application!) is started?

  - by Marcus

  I would like to have some eventhandler which raise if a new application is started. I've heard that this is possible by using a hook but the only examples I can find are based on mouse/keyboard events. What is an example link of how I can create such a hook in C#? Oh and btw: Nope, I don't want to use WMI which could be a solution as well but it's not an option in my case.

• Best way to get the highest sum from a Matrix (using Java but algorithm is the issue here)

  - by user294896

  Sorry I dont know the correct terminology to use but I have a 3x3 matrix like this 1 3 4 5 4 5 2 2 5 and I want get the highest score by picking a value from each row/column but I cant pick the same row or column more than once , so the answer in this case is 3 + 5 + 5 = 13 (row0,col1 + row1,col0 + row2,col2) 4 + 5 + 5 = 14 is not allowed because would have picked two values from col2 I'm using Java, and typically the matrix would be 15 by 15 in size. Is there a name for what Im trying to do, and whats the algorithm thanks Paul

• Is it possible to use SQL XML to insert, and get output from each record?

  - by nbolton

  I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible? I guess it doesn't matter if the result is/isn't XML, but the input certainly has to be.

  I'm looking at a database dump file, and I see many records in various tables with their version number set in values other than 0 (even 94 in one case). I understand it has to do with hibernate locking strategy, but my concern is that today is Sunday, and the site has almost no visitors so is: is this normal ? Or is there a known hibernate bug or even some programming malpractice producing this ?
