• Oracle Cursor and JDBC ODBC

  - by BeginnerAmongBeginners

  I have some procedures to execute in the database that has an OUT REFCURSOR parameter. When I am connecting with the JDBC thin client, everything works fine. However, if I were to change the connection string to refer to the ODBC data source pointing to the same database, those procedures will fail. The procedures that do not use an OUT REFCURSOR will still work fine though. Is this situation the result of an error on my part or expected?

• [C++] STL list - how to find a list element by its object fields

  - by Dominic Bou-Samra

  I have a list: list<Unit *> UnitCollection; containing Unit objects, which has an accessor like: bool Unit::isUnit(string uCode) { if(this->unitCode == uCode) return true; else return false; } How do I search my UnitCollection list by uCode and return the corresponding element (preferably it's index). I have looked at the find() method, but i'm not sure you can pass a boolean method in instead of a searched item parameter if that makes sense.

• Passing values into regex match function

  - by Tim

  In python (it's a Django filter), I'm doing this: lReturn = re.sub(r'\[usecase:([ \w]+)]', r'EXTEND WITH <a href="/usecase/%s/\1/">\1</a>' % pCurrentProjectName, lReturn) I'd like to use a function instead of a string (so I can check that the usercase is a valid name), so it would change to this: def _match_function(matchobj): lMatch = matchobj.group(1) return "EXTEND WITH <a href='/usecase/%s/%s/'>%s</a>" % (pCurrentProjectName, lMatch, lMatch) lReturn = re.sub(r'\[usecase:([ \w]+)]', _match_function, lReturn) How do I get pCurrentProjectName into the _match_function() function?

  I want to create some mad robust code. I want to take a query as a string, create a temporary view / table to store the results, use it, then drop the table.

• Multiple returns: Which one sets the final return value?

  - by DR

  Given this code: String test() { try { return "1"; } finally { return "2"; } } Do the language specifications define the return value of a call to test()? In other words: Is it always the same in every JVM? In the Sun JVM the return value is 2, but I want to be sure, that this is not VM-dependant.

• where can I get these kind of exercises to solve?

  - by flash

  Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.

• Perl Regular Expression [] for <>

  - by bmucklow

  So I am trying to read an XML file into a string in Perl and send it as part of a SOAP message. I know this is not ideal as there are methods for SOAP sending files, however, I am limited to having to use the SOAP that is set up, and it is not set up for sending with file support. Therefore I need to parse out the markup tags < and replace them with []. What is the best way to do this?

• What is the fastest XML parser in PHP?

  - by Jakub Lédl

  Hi, for a certain project, I need some way to parse XML and get data from it. So I wonder, which one of built-in parsers is the fastest? Also, it would be nice of the parser could accept a XML string as input - I have my own implementation of thread-safe working with files and I don't want some nasty non-thread-safe libraries to make my efforts useless.
