Rails Execute SQL

Execute SQL with execute_sql helper inside your Rails apps. Directly in rails console.

Usage

Simply add this gem into your Gemfile.

And for example call directly in rails console:

execute_sql "select count(*) from users where age > 50"

# see below for additional options.

OR in your models, controllers, or other parts of app:

ExecuteSQL.run "select count(*) from users where age > 50"

# or with different mode
# default mode: :print

# return array of HashWithIndifferentAccess objects
# please remember that arrays can be manipulated with Enumerable methods, but this is *not* a chainable ARel relation
ExecuteSQL.run "select * from users where age > 50", mode: :array

# return array of User objects
ExecuteSQL.run "select * from users where age > 50", mode: :array, klass: User

# return single value
ExecuteSQL.run "select count(*) from users where age > 50", mode: :single

# return array of results
ExecuteSQL.run "select * from users where age > 50", mode: :raw

# just execute and return nil
ExecuteSQL.run "truncate table users", mode: :none

Sample in controller:

class HomeController < ApplicationController
  def index
    @users = ExecuteSql.run "select * from users", mode: :raw
  end
end
