  • TSql Lookup function

    - by OldMan
    I have a bunch of dimension tables that have unique ID and Name fields. I need a T-SQL function that returns an ID when passed a table name and a value for the name field. I'm guessing the query would build a little query then execute it? Performance isn't an issue since this is a one time ETL thing.

  • mongodb java driver - raw command?

    - by Scott
    Is it possible to execute raw commands as javascript through the Java driver for MongoDB? I'm tired of wrapping everything in Java objects using Rhino, and would happily sacrifice performance for the convenience of passing javascript directly through to the DB. If not, I can always use sleepymongoose or something, but I don't really want to add yet another language (python) to the stack at this point. Any insights are appreciated.

  • Confusing If Statement?

    - by NetSide
    I always use If statement (In C#) as (1. Alternative); if (IsSuccessed == true) { // } I know that there is no need to write "== true" as (2. Alternative)); if (IsSuccessed) { // } But, I use it because it is more readable and cause no performance issue. Of course, this is my choice and I know many software developers prefer first alternative. What is the best usage, and Why?

  • Is it wrong for a context (right click) menu be the only way a user can perform a certain task?

    - by Eric
    I'd like to know if it ever makes sense to provide some functionality in a piece of software that is only available to the user through a context (right click) menu. It seems that in most software I've worked with the right click menu is always used as a quick way to get to features that are otherwise available from other buttons or menus. Below is a screen shot of the UI I'm developing. The tree view on the right shows the user's library of catalogs. Users can create new catalogs, or add and remove existing catalogs to and from their library. Catalogs in their library can then be opened or closed, or set to read-only. The screen shot shows the context menu I've created for the browser. Some commands can be executed independently from any specific catalog (New, Add). Yet the other commands must be applied to a specifically selected catalog (Close, Open, Remove, ReadOnly, Refresh, Clean UP, Rename). Currently the "Catalog" menu at the top of the window looks identical to this context menu. Yet I think this may be confusing to the users as the tree view which shows the currently selected catalog may not always be visible. The user may have switched to the Search or Filters tab, or the left pane may be hidden entirely. However, I'm hesitant to change the UI so that the commands that depends on a specifically selected catalog are only available through the context menu.

    What allocators are available out there for use with STL when dealing with small objects. I have already tried playing with pool allocators from Boost, but got no performance improvement (actually, in some cases there was considerable degradation).

  • MySQLi - Should every statement be prepared?

    - by Kerry
    I know its supposed to improve performance and clean strings, but lets say there are no variables? Might just be a SELECT COUNT( `column` ) AS count FROM `table` Should that be prepared? Is there any case that a SELECT statement should not be prepared?

  • Jquery live() vs delegate()

    - by PeeHaa
    I've read some posts here and on the web about the differences of live() and delegate(). However I haven't found the answer I'm looking for (if this is a dupe please tell me). I know the difference between live and delegate is that live can not be used in a chain. As I also read somewhere delegate is in some case faster (better performance). So I am wondering is there a situation where you would use live instead of delegate?
