Hello, JDBC Type1(Oxygene) World!

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 Oxygene 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（Oxygene + JDBC Type1 + ODBC + Jet データベース）
namespace hello;
interface
uses
java.sql.*,
sun.jdbc.odbc.*;
type
Hello = class
public
class method Main(args: array of String);
end;
implementation
class method Hello.Main(args: array of String);
var
conn: Connection;
stmt: Statement;
rs: ResultSet;
begin
java.lang.Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn := DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=.\\hello.mdb", "", "");
stmt := conn.createStatement();
rs := stmt.executeQuery("SELECT 'Hello, JDBC Type1 World!' AS Message");
while rs.next() do begin
System.out.println( rs.getString(1) );
end;
rs.close();
stmt.Close();
conn.Close();
end;
end. |
namespace hello;
interface
uses
java.sql.*,
sun.jdbc.odbc.*;
type
Hello = class
public
class method Main(args: array of String);
end;
implementation
class method Hello.Main(args: array of String);

while rs.next() do begin
System.out.println( rs.getString(1) );
end;
rs.close();
stmt.Close();
conn.Close();
