Execute SQL with execute_sql helper inside your Rails apps. Directly in rails console.
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: :noneSample in controller:
class HomeController < ApplicationController
