Writing a SQL Query in Active Record?

Hi,

I am using the following code snippet for connecting to SQL Server
through Active Record:

require ‘rubygems’
require ‘active_record’

ActiveRecord::Base.establish_connection(
:adapter => “sqlserver”,
:host => “xxx.xxx.xxx.xxx,8080”
:username => “username”
:password => “password”
:database => “xyz_1008”
)

Now, I want to execute a query in this sql server after getting
successfully connected but am not aware how to do so. Can anyone give an
example as to how we write the query say (“Select * from Name”) after
establishing the above connection successfully?

Thanks,
Anukul

Look for #find, or #find_by_sql.

Hi,

Thanks for the reply.

I am not using rails. Want to run the query only using Active Record on
Ruby (Scite Editor)

Can you give any prototype as to how I can proceed writing a simple
“SELECT” query after establishing the connection with the sql server db?

Thanks,
Anukul

Yes, that is what ActiveRecord’s #find and #find_by_sql methods do.

Rails uses ActiveRecord, but ActiveRecord works without using Rails
itself.

class Table < ActiveRecord::Base; end

select = Table.find :all

What’s ActiveRecord for if you just want to use SQL?

The normal ActiveRecord way is to create a Class and let it do that.
