Suggestions or improvements, please! /// <summary> /// Compares two specified version strings and returns an integer that /// indicates their relationship to one another in the sort order. ...

in a DB2 trigger, I need to compare the value of a CLOB field. Something like: IF OLD_ROW.CLOB_FIELD != UPDATED_ROW.CLOB_FIELD but "!=" does not work for comparing CLOBs. What is the way to compare it? Edited to add: My trigger needs to do some action if the Clob field was changed during an update. This is the reason I need to comp...

As part of the base class for some extensive unit testing, I am writing a helper function which recursively compares the nodes of one XmlDocument object to another in C# (.NET). Some requirements of this: The first document is the source, e.g. what I want the XML document to look like. Thus the second is the one I want to find differ...
Hi, We're going through a massive migration project at the minute and trying to validate the code that is deployed to the live estate matches the code we have in source control. Obviously the .net code is easy to compare because we can disassemble. I don't believe this is possible in vb6 exes because of the manner of compilation. Does...
We have a "master database structure", and need a routine to keep the database structure on client sites up-to-date. A number of suggestions have been given to a related question, but I am looking for a more specific solution, along these lines: I would like to generate a text file (XML or other readable format) which describes the en...
I have a form that is sending in sizes of things, and I need to see what the strings are equal to so that I can set the price accordingly. When i try to do this, it says that they are not equal, and i get no prices. This is the code i'm using: if ($_POST['sizes'] == "Small ($30)"){$total = "30";} if ($_POST['sizes'] == "Medium ($40)"){$...

I need to write a tool in C++ to determine the changed bits in a file compared against another file for replication. What would be the best method of accomplishing this? I don't have a specific OS or library in mind, I'm open to suggestions. My primary goal is reducing the amount of network traffic involved in replicating. ...
I need to compare the integer part of two doubles for inequality and I'm currently doing this: int iA = (int)dA; int iB = (int)dB; if( iA != iB ) { ... } but I wonder if there's a better approach than this. Thanks. If I used Math.Truncate() instead of a cast to int, would it still be accurate to compare the two resulting double...
I'm experiencing a strange issue where my Visual Studio 2005 C++ program crashes the first time it runs after a new build. I'm having a difficult time debugging this intermittent issue and I suspect it's somehow related to a file somewhere on my hard drive that is being changed. If I can find the file(s), that might provide some more i...
Hi, in C++ I have two chars holding hex values e.g.: char t = 0x4; char q = 0x4; How would i compare if the two values held in the char are the same?? I tried if (t == q) // should give me true but no, any help, thanks! ...
I need to be able to compare some month names I have in an array. It would be nice if there were some direct way like: Month.toInt("January") > Month.toInt("May") My Google searching seems to suggest the only way is to write your own method, but this seems like a common enough problem that I would think it would have been already imp...
I'd like to compare two consecutive elements in a std::list while iterating through the list. What is the proper way to access element i+1 while my iterator is at element i? Thanks Cobe ...
You can pass a function pointer, function object (or boost lambda) to std::sort to define a strict weak ordering of the elements of the container you want sorted. However, sometimes (enough that I've hit this several times), you want to be able to chain "primitive" comparisons. A trivial example would be if you were sorting a collectio...
I have an enumeration: ENUM( 'alpha', 'beta', 'gamma', 'delta', 'omega' ) If I sort my table by this column I get them in the correct order defined above. However, I can't find a way to select a subset of these, e.g. everything before delta. Using WHERE status < 'delta' only returns alpha and beta, not gamma. It seems MySQL uses a stri...
