This module allows Ruby programs to interface with the SQLite3 database engine (www.sqlite.org). You must have the SQLite engine installed in order to build this module.
Note that this module is only compatible with SQLite 3.6.16 or newer.
require "sqlite3" # Open a database db = SQLite3::Database.new "test.db" # Create a table rows = db.execute <<-SQL create table numbers ( name varchar(30), val int ); SQL # Execute a few inserts { "one" => 1, "two" => 2, }.each do |pair| db.execute "insert into numbers values ( ?, ? )", pair end # Find a few rows db.execute( "select * from numbers" ) do |row| p row end # Create another table with multiple columns db.execute <<-SQL create table students ( name varchar(50), email varchar(50), grade varchar(5), blog varchar(50) ); SQL # Execute inserts with parameter markers db.execute("INSERT INTO students (name, email, grade, blog) VALUES (?, ?, ?, ?)", ["Jane", "[email protected]", "A", "http://blog.janedoe.com"]) db.execute( "select * from students" ) do |row| p row end
Install SQLite3, enabling the option SQLITE_ENABLE_COLUMN_METADATA (see www.sqlite.org/compile.html for details).
Then do the following:
ruby setup.rb config ruby setup.rb setup ruby setup.rb install
Alternatively, you can download and install the RubyGem package for SQLite3/Ruby (you must have RubyGems and SQLite3 installed, first):
gem install sqlite3
If you have sqlite3 installed in a non-standard location, you can specify the location of the include and lib files by doing:
gem install sqlite3 -- --with-sqlite3-include=/opt/local/include \ --with-sqlite3-lib=/opt/local/lib
The best place to get help is from the sqlite3-ruby mailing list which can be found here:
* http://groups.google.com/group/sqlite3-ruby
Uh oh. After contacting the mailing list, you’ve found that you’ve actually discovered a bug. You can file the bug at the github issues page which can be found here:

For help figuring out the SQLite3/Ruby interface, check out the SYNOPSIS as well as the RDoc. It includes examples of usage. If you have any questions that you feel should be addressed in the FAQ, please send them to the mailing list
