• xcode scripting language

  - by PurplePilot

  i notice that Java has a number of ancillary scripting languages. Clojure and Groovy for example. My understanding is that these can be used when the full might and power of Java does not need to be applied and a speedy cludge can be hacked in Groovy/Clojure. But at the end of the day the scripting tools contribution gets compiled into the application Question 1) Is there a similar scripting in x-code? I was not so interested in Python or Ruby in this situation as they are languages in their own right added in, as indeed i think can happen in Java, but i was looking for a purpose built tools. Question 2) If there is such a tool would it count the application out vis-a-vis the new Apple guidelines as to what can be used to generate iXxx apps?

• Login implementation for windows mobile

  - by pdiddy

  What is a good approach for credential checks for windows mobile app. Knowing that it is an occasionally connected device. Should I keep the user credential into the local database? If the credential doesn't exist in the db, try to see if it has internet access and do the check through a web service? If both fails then display an error message ? If logins is successful then store the credential to the local database store then upon next login go against the database first? Is this a good approach?

• Good workflow for website design

  - by Olav

  I would like some idea about a good workflow for Website Design, with a high degree of "offshoring" (Elance, Odesk etc.). I would to do as much as possible "pre production", with client input, ideas etc. stored in IA diagrams, wireframe mockups etc. in something like a Wiki. Also a like the idea about having different people come up with different design proposals. Wouldlike to have some ideas of costs of different phases and tasks ($, %, hours). With Design I mean roughly the aspects of a site that can be done with client-side tools, especially XHTML and CSS. What other tools should I use than IA diagrams.

• Java - JPA - Generators - @SequenceGenerator

  - by Yatendra Goel

  I am learning JPA and have confusion in the @SequenceGenerator annotation. Upto my understanding, it automatically assigns a value to numeric identity fields/properties of an entity. Q1. Does this sequence generator make use of the database's increasing numeric value generating capability or generates the number on his own? Q2. If JPA uses database auto increement feauture, then will it work with datastores that don't have auto increement feature? Q3. If JPA generate numeric value on his own, then how the JPA implementation knows which value to generate next? Does it consult with the database first to see what value was stored last so as to generate the value (last + 1). ====================================================================================== Q4. Please also throw some light on sequenceName and allocationSize properties of @SequenceGenerator annotation.

• Zend Framework multiple databases

  - by Uffo

  I'm currently using only one database with Zend Framework, but now I have to add ONE MORE.

• NHibernate MySQL Enum

  - by LnDCobra

  I am trying to access the "MYSQL" database tables to create a GUI for adding users and privileges. Doing this, I have run into my first NHibernate problem. How do i map MySQL Enum's to a C# Boolean? Or if not possible then to at least a Enum? The database fields are delcared as enum('N', 'Y') These are all of the privilege fields in the database. Now is there anyway of getting this into an enum or even better, boolean in C#/NHibernate? Edit #1: In C# if I need to declare an enum it will be the following: enum YesNoEnum { Yes, No }

• ASP.NET 3.5 Stateless Session Managment and connection pooling?

  - by Norm

  I am designing an ASP.NET (3.5) web application that connects to a Rocket Software UniVerse database. I am in the planning stages right now and need some help in being pointed in the right direction. I am brand new to ASP and C#. I am shooting for a RESTful design and a MVC pattern. Rocket provides a .NET library called UniObjects.NET which handles everything for connecting and retrieving information from the database. What would be the best way to in general to log my users into the database, then use that session via connection pooling? I see that in 3.5 there is the ASP.NET Routing Infrastructure and that looks promising am I in the right direction on this? Also does C# support decorators like Python and Java?

• SQL Server 2008 - Get Geography From Record

  - by user336786

  Hello, I am new to using the geography types in SQL Server 2008. I have a table in my database called "Location". "Location" has the following columns and types: Location -------- City nvarchar(256) State nvarchar(256) PostalCode nvarchar(25) Latitude decimal(9, 6) Longitude decimal(9, 6) Each Location is related to a Store record in my database. I am trying to find the stores within a 10 mile radius or postal code or city/state that a user enters. To accomplish this, I know that I need to rely on geographies. At this time I have: DECLARE @startingPoint geography; SET @startingPoint=geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326); That gives me the starting point from a hard-coded textual value. However, I do not know how to convert a lat/long from my Location table into a geography instance. How do I convert a lat/long in my database to a geography instance so I can continue to work on my query? Thank you!

• To be a lazy developer or not to be a lazy developer?

  - by JamesStuddart

  Am I a lazy developer? Is it being lazy to use automated tools, such as code generators and such? Now, I could, if I had to, create all the data layers and entities I needed, but I choose to use CodeSmith to generate my datalayers and entities. I also use Resharper and I would say it fights with MSDeploy as to which gets installed first after Visual Studio. Again if I had to, I could code without it, but prefer not to. Both these tools from my point of view are no brainers as they improve output massively. But is this lazy? I'm sure there are purists out there that would say everything should be wirtten by you so you know what everything is doing, but if you can read through the code and see what is happening is that ok? So am I being lazy or am I just using all the cards in my hand?

• Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

  - by Jay

  I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

• Cloud sync between iPad/iPhone app

  - by Macatomy

  I have a Core Data app that will end up being an iPhone/iPad universal application. I would like to implement cloud syncing so that an iPhone and an iPad both running the app could share data. I'm planning to use the recently released Dropbox API. Does anyone have any thoughts on the best way to go about doing this? The Dropbox API allows for apps to store files on the cloud. What I was thinking was to original store the database (sqlite) for the app on the cloud and then download that database, but I then realized that using that method would make it painfully difficult to merge changes (rather than replacing the whole database). Any thoughts are appreciated. Thanks.

• Products combining framework and visual IDE for web development?

  - by Tom Hubbard

  We are looking for some tools to help us with our web development speed. The two main areas that we have pinpointed as parts of the problem are "Framework/Flow Management" and "Visual/Layout Development" Ideally we would find a tool that handles both rather well. However, it seems like there are few tools that handle the middle ground well. Usually it is just a Framework, or and IDE, not both. The best thing we have found so far is Agile Platform. Are we missing any obvious products? Platform at this point is not a huge concern. We can migrate to the best tool.

• Mapping enum to a table with hibernate annotation

  - by Thierry-Dimitri Roy

  I have a table DEAL and a table DEAL_TYPE. I would like to map this code: public class Deal { DealType type; } public enum DealType { BASE("Base"), EXTRA("Extra"); } The problem is that the data already exist in the database. And I'm having a hard time mapping the classes to the database. The database looks something like that: TABLE DEAL { Long id; Long typeId; } TABLE DEAL_TYPE { Long id; String text; } I know I could use a simple @OneToMany relationship from deal to deal type, but I would prefer to use an enum. Is this possible? I almost got it working by using a EnumType.ORDINAL type. But unfortunately, my IDs in my deal type table are not sequential, and do not start at 1. Any suggestions?

• How to create and restore a backup from SqlAlchemy?

  - by swilliams

  I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

• MySQL Query involving column names containing math operators

  - by devil_fingers

  I'm a MySQL scrub, and I have asked around and checked around the internet for what I'm sure will turn out to be something obvious, but I'm very frustrated with what I thought would be a very, very simple query not working. So here goes. Please be gentle. Basically, in a large database, some of the column names contain mathematical operators like "/" and "+." (Don't ask, it's not my database, I can't do anything about it). Here is the "essence" of my query (I took out the irrelevant stuff for the sake of this question): SELECT PlayerId, Season, WPA/LI AS WPALI FROM tht.stats_batting_master WHERE Season = "2010" AND teamid > 0 AND PA >= 502 GROUP BY playerid ORDER BY WPALI DESC When I run this, it returns "Unknown column 'LI' in 'field list'," I assume because it sees the "/" in WPA/LI as a division sign. Like I said, I'm sure this is easy enough to work around (it must be given how much this database is used), but I haven't' been able to figure out how. Thanks in advance for any help.

• Failed to execute stored procedure from the JDBC code using mysql connection

  - by Purushotham

  Hi, I have one database. I executed a stored procedure on it. I wrote some JDBC code to connect to this database. When I am calling this stored procedure from my JDBC code it is throwing SQLException. One interesting thing I found is that I have one user other than root user. This user has all the privileges to this database where the stored procedure is present. When I use the root user I am able to call the stored procedure successfully. But with the other user I am getting SQLexception. I am not able to find why it happens like this. For sure I want this user(other than root) has to call this stored procedure successfully. Thanks in advance.

• advise on pointing reporting service data sources

  - by pearcewg

  It's possible I am unable to resolve this because I have been spoiled in other DEV environments where I had one database server for each reporting server. I need some advise on how to point a single SQL Server reporting server to multiple database servers. These databases correspond to DEV, TEST and QA environments. The way the reporting is currently configured I am unable to toggle between environments gracefully. Any advise would be greatly appreciated.

• Better understanding of my SQL transactions

  - by Slew Poke

  I just realized that my application was needlessly making 50+ database calls per user request due to some hidden coding -- hidden in the sense that between LINQ, persistence frameworks and events it just so turned out that a huge number of calls were being made without me being aware. Is there a recommended way to analyze individual transactions going to my SQL 2008 database, preferably with some integration to my Visual Studio 2010 environment? I want to be able to 'spy' on individual transactions being made, but only for certain pieces of my code, and without making serious changes to either the code or database.

• Comments on this assumption about running on dev server vs a real instance in app engine (python)?

  - by Jacob Oscarson

  Hello app engineers! I'm on an app engine project where I'd like to put in a link to a Javascript test runner that I'd like to only exist when running the development server. I've made some experiments on a local shell with configuration loaded using the technique found in NoseGAE versus live on the 'App Engine Console' [1] and it looks to me like a distinction btw real instance and dev server is the presence of the module google.appengine.tools. Which lead me to this utility function: def is_dev(): """ Tells us if we're running under the development server or not. :return: ``True`` if the code is running under the development server. """ try: from google.appengine import tools return True except ImportError: return False The question (finally!) would be: is this a bad idea? And in that case, can anyone suggest a better approach? [1] http://con.appspot.com/console/ (try it! very handy indeed)
