• Connect to MySQL in Ruby using NetBeans

  - by Varun

  I've downloaded the "dbd-mysql-0.4.4.zip" and linked it to my project. While I try to run a demo code from NetBeans the very first line require "dbi" gives me an error. Is there a different way to do it? I also tried jruby setup.rb config --with=dbi,dbd_mysql from the command prompt and it gave me the following error: config: unknown option --with=dbi,dbd_mysql Try 'ruby setup.rb --help' for detailed usage. Any suggestions please?

• Python inter-computer communication.

  - by matt1024

  This whole topic is way out of my depth, so forgive my imprecise question, but I have two computers both connected to one LAN. What I want is to be able to communicate one string between the two, by running a python script on the first (the host) where the string will originate, and a second on the client computer to retrieve the string. What is the most efficient way for an inexperienced programmer like me to achieve this?

• mysql left join queries

  - by Mike79

  I have a question about the snippet below. I'm wondering, if the first query doesn't bring any results, would I still get the results for the second query? select * from ( -- first query ) as query1 left join ( -- second query ) as query2 on query1.id=query2.id left join ( -- third query ) as query3 on query1.id=query3.id; Update: what I need is a full join, however, MySQL does not support it, what would be a good way to emulate this?

• Pure python implementation of greenlet API

  - by Tristan

  The greenlet package is used by gevent and eventlet for asynchronous IO. It is written as a C-extension and therefore doesn't work with Jython or IronPython. If performance is of no concern, what is the easiest approach to implementing the greenlet API in pure Python. A simple example: def test1(): print 12 gr2.switch() print 34 def test2(): print 56 gr1.switch() print 78 gr1 = greenlet(test1) gr2 = greenlet(test2) gr1.switch() Should print 12, 56, 34 (and not 78).

  - by Kerry

  When I am grabbing data from my table that require permissions, should all the permission be done there? Such as checking for an admin or if they can view the data (in MySQL)? Or should I grab it if they have a record at all, then check the specific actions (such as view, add, edit, delete) on the PHP side?

• Why would restarting MySQL make my site faster?

  - by beagleguy

  hey all, my site started dragging lately, the queries taking exceptionally longer than I would expect with properly tuned indexes. I just restarted the mysql server after 31 days uptime and every query is now substantially faster and the whole site renders 3-4 times faster. Would there be anything that jumps out at you as to why this may have been? Improper settings on my.cnf perhaps? Any ideas as to what I can start looking at to try and pinpoint why? thanks

• mysql circular dependency in foreign key constraints

  - by Flavius

  Given the schema: What I need is having every user_identities.belongs_to reference an users.id. At the same time, every users has a primary_identity as shown in the picture. However when I try to add this reference with ON DELETE NO ACTION ON UPDATE NO ACTION, MySQL says #1452 - Cannot add or update a child row: a foreign key constraint fails (yap.#sql-a3b_1bf, CONSTRAINT #sql-a3b_1bf_ibfk_1 FOREIGN KEY (belongs_to) REFERENCES users (id) ON DELETE NO ACTION ON UPDATE NO ACTION) I suspect this is due to the circular dependency, but how could I solve it (and maintain referential integrity)?
