CsvToSqlite3 is a gem that aims to work as a executable like rake or bundler, it servs as a Sqlite3 database generator from csv files. It is used to create and insert all data from one or more csv files to the same Sqlite3 database.
The ideia comes from a specific cenario when I needed to run complex sql queries on a huge database, and once I was afraid to run it directly in prolduction and it impacts in the operation I chose to run simples selects (select * from some_table when created_at > some_date) from each table used on my query, export to csv files than create a specific ruby script that create a sqlite3 database and run the inserts, thereby i can run any havy query on my local computer without generate any impact in the operation.
Once this cenario is quite common I decided to rewrite the script to work with any csv file exported from any table.
Installed with gem:
$ gem install csv_to_sqlite3
Once the gem is installed it is aviable the command "csv_to_sqlite", to generate a new database you need to run on terminal "csv_to_sqlite path/to/file.csv'". It will create a file named data.sqlite3 and create a table with name equal to file name, case the table already exists it will only insert all data from this file.
$ csv_to_sqlite stores.csv
By running the command above it will be generated a database data.sqlite3 with a table named stores with all data included.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
