RawSqlBuilder

This gem is to ease the pain of mass creating and updating object attributes in your database. It will adapt to different tables, columns, and column-types. Will dramatically speed up mass creates/updates.

• Raw Sql Rules:
  • Keys being assigned to can be without quotes or surrounded by double quotes
  • Double quotes are recommended to prevent a column name from being confused with an action. Ex: column name "order"
  • Values being assigned must be surrounded by single quotes
  • Hashes:
  • No exterior curly braces
  • A hash within the value of another hash must be surrounded by double quotes
  • Interior hash quotes must be escaped double quotes
  • Interior hash must use : not =>
  • Ex: '"main"=>"\"key\":\"value\""'

Installation

Add this line to your application's Gemfile:

gem 'raw_sql_builder'

And then execute:

$ bundle

Or install it yourself as:

$ gem install raw_sql_builder

Usage

Pass through a collection or array of objects to one of the methods below. Will also accept a single object.

• Creating:

  • Use the method 'new' to create new objects without saving them to the database.
  • Once all objects have attributes assigned, pass them through to mass_create or mass_create_or_update to be created.

• Updating:

  • Assign attributes to objects, I prefer using the method 'assign_attributes.'
  • Once all attributes are assigned for all objects pass them through to mass_update or mass_create_or_update for updating.

• Methods:

  • mass_create(objects)
  • This will only do a creation query and include objects that return true on 'new_record?'
  • Any existing objects that have updated attributes and were passed through will be ignored.
  • mass_update(objects)
  • Will only update existing objects and ignore new objects.
  • mass_create_or_update(objects)
  • Will separate new objects and updated objects, then run respective queries.
  • execute(query)
  • Will execute the query you pass through.
