Houses Sequel’s JDBC support when running on JRuby.
Contains procs keyed on subadapter type that extend the given database object so it supports the correct database type.
The types to check for 0 scale to transform :decimal types to :integer.
Used to identify a jndi connection and to extract the jndi resource name.
Attempt to load the JDBC driver class, which should be specified as a string containing the driver class name (which JRuby should autoload). Note that the string is evaled, so this method is not safe to call with untrusted input. Raise a Sequel::AdapterNotFound if evaluating the class name raises a NameError.
# File lib/sequel/adapters/jdbc.rb, line 53 def self.load_driver(drv, gem=nil) load_gem(gem) if gem eval drv rescue NameError raise Sequel::AdapterNotFound, "#{drv} not loaded#{", try installing jdbc-#{gem.to_s.downcase} gem" if gem}" end
Allow loading the necessary JDBC support via a gem.
# File lib/sequel/adapters/jdbc.rb, line 35 def self.load_gem(name) begin require "jdbc/#{name.to_s.downcase}" rescue LoadError # jdbc gem not used, hopefully the user has the .jar in their CLASSPATH else if defined?(::Jdbc) && ( ::Jdbc.const_defined?(name) rescue nil ) jdbc_module = ::Jdbc.const_get(name) # e.g. Jdbc::SQLite3 jdbc_module.load_driver if jdbc_module.respond_to?(:load_driver) end end end
