Comments on: Stored Procedures and Rails – Part 1 http://nasir.wordpress.com/2007/12/03/stored-procedures-and-rails/ on ruby, rails and other stuff Sat, 23 Mar 2013 10:48:21 +0000 hourly 1 http://wordpress.com/ By: Kai http://nasir.wordpress.com/2007/12/03/stored-procedures-and-rails/#comment-1475 Thu, 03 Jan 2013 14:13:01 +0000 http://nasir.wordpress.com/2007/12/03/stored-procedures-and-rails/#comment-1475 This was a very helpful post for me. However, when calling complex stored procedures with several result sets, I get strangely structured arrays/hashes and incomplete results with the method “connection.select_all”. I solved this problem by using “ActiveRecord::Base.execute_procedure”, as suggested on the official github site for the sql server adapter:

Basically you need to reconnect “ActiveRecord::Base.connection.reconnect!”

as somehow mysql just drops the connection. I am not sure why.

I tried to add the code on an existing model. It just does not work.

However, any further call to the same stored procedure returns a “Commands out of sync” error.

I need to call a postgre stored procedure i did program some time ago, so I copied the code you suggets before.
I created the class DbStoredProcedure

2. why do you think it is not working,

When I call any method of the class it does not return anything or show any error, simply nothing happens

3. which db you are using, and

Postgres

4. any other information or errors, etc.

I am totally “new” using Ruby on Rails
I think I need a functional example, to understand better.

Can I have an example please?.

It is a really great to be able to find some solution when there is no core solution.

Anyway, for RoR to be able to be an enterprise class programming language and framework using stored procedures and views in an database should be part of core.
I’m not sure if there are RoR developers that are aware that procedures are best way to implement database logic, except for maybe some trivial models. That’s why I believe using stored procedures should be supported by core ActiveRecord and defined per each available datrabase adapter to support different usages. One ExecProc! should do it…
Also did anyone notice availability explicit of START TRANSACTION END TRANSACTION implementations? These are like crucial for any serious developement.
