JDBC Type1
JDBC（Java Database Connectivity）は、Java 用のデータベース接続 API である。実装方法によりType1～4の４つのタイプが存在する。
Type1 は JDBC と ODBC の API をマップさせたブリッジドライバである。
以下は JRuby による JDBC ライブラリの使用例となっている。
ソースコード（JRuby + JDBC Type1 + ODBC + Jet データベース）
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=hello.mdb", "", "")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close |
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=hello.mdb", "", "")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close
ソースコード（JRuby + JDBC Type1 + ODBC + ACE データベース）
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=.\hello.accdb", "", "")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close |
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=.\hello.accdb", "", "")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close
ソースコード（JRuby + JDBC Type1 + ODBC + SQL Server）
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={SQL Server};SERVER=(local)", "sa", "P@ssW0rd")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close |
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={SQL Server};SERVER=(local)", "sa", "P@ssW0rd")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close
ソースコード（JRuby + JDBC Type1 + ODBC + Oracle）
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Oracle in OraDb11g_home1};DBQ=ORCL", "scott", "tiger")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message FROM DUAL")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close |
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={Oracle in OraDb11g_home1};DBQ=ORCL", "scott", "tiger")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message FROM DUAL")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close
ソースコード（JRuby + JDBC Type1 + ODBC + MySQL）
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={MySQL ODBC 5.1 Driver};Server=localhost", "root", "P@ssW0rd")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
rs.close
stmt.close
conn.close |
require 'rubygems'
require 'java'
Java::sun.jdbc.odbc.JdbcOdbcDriver
conn = java.sql.DriverManager.get_connection("jdbc:odbc:Driver={MySQL ODBC 5.1 Driver};Server=localhost", "root", "P@ssW0rd")
stmt = conn.create_statement
rs = stmt.execute_query("SELECT 'Hello, JDBC Type1 World!' AS Message")
while (rs.next) do
puts rs.getString(1)
end
