Module: ArJdbc::Abstract::Core

Included in:
ActiveRecord::ConnectionAdapters::JdbcAdapter, ActiveRecord::ConnectionAdapters::PostgreSQLAdapter, ActiveRecord::ConnectionAdapters::SQLite3Adapter
Defined in:
lib/arjdbc/abstract/core.rb

Overview

This is minimum amount of code needed from base JDBC Adapter class to make common adapters work. This replaces using jdbc/adapter as a base class for all adapters.

    spec = @config.key?(:adapter_spec) ? @config[:adapter_spec] :
               ( @config[:adapter_spec] = adapter_spec(@config) ) # due resolving visitor
    extend spec if spec

#jdbc_connection(unwrap = nil) ⇒ Java::JavaSql::Connection

Retrieve the raw java.sql.Connection object. The unwrap parameter is useful if an attempt to unwrap a pooled (JNDI) connection should be made - to really return the 'native' JDBC object.

Parameters:

  • unwrap (true, false) (defaults to: nil) —

    whether to unwrap the connection object

Returns:

  • (Java::JavaSql::Connection) —

    the JDBC connection
