What is “Agente” that prevent me to upgrade?

Thank’s Michele.

it may change your opinion about blocks.

Sometimes getting the job done is not as good as getting the job done in a secure way.

In associating me with the ibm_db driver you are not far off. I initially developed the adapter for Rails using the ibm_db driver and I’m active in promoting and supporting DB2 and Ruby/Rails, since I’m part of the IBM DB2 team. Searching for ibm_db, you’ll find my name all over the place. However it is a different team that develops the driver from Sam Ruby’s initial contribution. The same team also takes care of the Python driver and is currently maintaining the ActiveRecord adapter.

It’s sad that PHP’s interface was taken, since it’s ugly. But beauty is in the eye of the beholder, or so they say.

Thanks for this article. I didn’t know how IBM’s driver looked like.

I’m glad there’s an alternative for Informix users.

Also, please note that I’m not the driver implementer, but you can forward your suggestions to opendev at us dot ibm dot com.

Any Ruby user will tell you that code above is not Ruby-ish, at all.

It lacks one of the most distinguishable and useful features of Ruby: blocks.

Iterations and resource management are easily written with blocks.

Maybe you can get some ideas from the following code, written with Ruby/Informix, that does the same as your second example, but with less clutter.

require 'informix'

Informix.connect("sample", "db2inst1", "mypassword") do |conn|
  sql = "SELECT * FROM EMPLOYEE"
  conn.cursor(sql) do |cur|
    cur.open
    cur.each_hash do |row|
      puts "#{row['FIRSTNME']} #{row['LASTNAME']}: #{row['EMPNO']}"
    end
  end
end

Informix resources are automatically freed when the block ends, for any reason (normal or abnormal).

I’ll try to write something about it in my blog soon.
