We should check if the map of the table actually succeeds, and also free resources accordingly. This fixes the kernel panic reported by Tetsuo Handa.

Hi all, I''m confused about how migrations work. I''ve been using them for a couple of weeks but haven''t had any serious rollback issues yet. Just now I added a field to a table with a migration and ran "rake migrate", which added the field as expected. This was in the file db/migrate/007_mymigration.rb, making it version 7. Later I changed my mind and

Can nsd 2.3.3 make load balancing? Example: www 600 IN A 10.0.0.1 600 IN A 10.0.0.2 600 IN A 10.0.0.3 Greet Sebastian Schikora

are working now, using our own implementation of a COM-RPC-Server. If you want to test a Server/Client-Pair - here's our free Download: www.datenhaus.de/Downloads/dh_RPC.zip For a successful test under wine, you have to Install the Redistributables of an actual VB6-Runtime and some ADO-Distributable >=2.5 first. I've tested the whole thing under a Debian-Sid with a somewhat older

Hi all, I have the following sql query that I am executing on a machine with single core. I want to know how can I execute the same sqery on a maching that is running with 4 cores. Please provide me the code. NEW_TABLE <- rhive.query("SELECT A, B, COUNT(C) FROM TABLE_A WHERE A>='01-01-2012'") Also let me know how can I leverage only 2 / 3 cores of the machine.

I''ve created a class method in my model called find_filtered. The intent is that I take various params that the user has submitted, and let the model build the query and return the AR collection, which is exactly what happens. However, now I''d like to paginate the recordset. Everything I''ve been able to find about pagination presumes that you have no pre-existing AR

Ive recently been contemplating how to tackle allowing for extra "fields" to be added to a recordset. For example, a user has an email address, but they may also want to put their birthday, height, weight, etc. I don''t want to constrain what is possible in this situation. I think what I''m describing is best documented in Philip Greenspun''s page here:

Hi, I am just starting of in rails. I am trying to understand the features of rails and I have this burning question. (and search is not available now): Apart from relying on the automatic CRUD sql script produced, is there a way I can create my own sql script ex: with many joins between exixting tables (for reporting ). All I need is to declare the custom query and place the result in a

HI: Is it possible to use the RODBC package within MS Access. I have been using from R but was just wondering if it could be used along with R(D)COM. Something like this: Dim dbs As DAO.Database Dim rst As DAO.Recordset Dim myApp As StatConnector Set myApp = New StatConnector myApp.GetErrorText myApp.Init "R" myApp.EvaluateNoReturn "library(RODBC)" myApp.EvaluateNoReturn

Hi, I''m considering migrating my site from php to RoR. I''ve installed RoR gone through the onlamp tutorials and made the recipie/todo list sample sites and tinkered with a few of my own. I understand the examples that use models and scaffolding to map tables, but I''m having a little trouble understanding how to handle general purpose queries. A few people have

Hi all! I am quite new to rails, and I would like to know if there is a tutorial, or if someone can tell me how to use rails with stored procedures and views. Any help would be appreciated. Thanks to all -- ------------------------------------------- Gioachino Bartolotta

Hello, This forum has been very helpful to me in the past, and I've run out of ideas on how to solve my problem. I had been using R and MySQL (and Perl) together for quite some time successfully on my Windows XP machine. However, I recently had some problems with MySQL (the ibdata file had become 35GB on my hard drive, turns out it's a known bug with InnoDB), and ultimately the way I

I have searched for days for an example that demonstrates what i would like to do, and this morning i thought i''d worked it out, but no....here''s what i have: Controller ========== class ProfilesController < ApplicationController def friends current_user.profile.friends end def list_friends @profile_pages, @profiles = paginate( friends, :per_page => 10) end end

I''ve inherited an EAV database and there''s really no option to remodel it. Data is stored as key_name, key_value pairs Trying to return a meaningful, unified recordset is far too complex to be efficient. I''ve decided to make use of the MySQL GROUP_CONCAT, and CONCAT_WS functions to return a fast query result, with the consolidated fields as one string. The final data is

I''m using ActiveRecord for an Extract and Transform operation, so it is outside of its native environment of Rails. I am running into a problem with memory consumption when I retrieve large amounts of data. By large amounts I am talking about roughly 12,700 records that each have a one to many relationship with about 15 additional types of information. One of those types happens

I''ve made a research patch [1] for Active Record which creates a new interface for working with limit and offset parameters, and it needs implementations for the commercial databases. The patch is described in detail in trac ticket #795 [2]. I''d greatly appreciate any contributions you can make as soon as possible so that this fix can make it in to the Rails 1.0 release.

Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <
