SQLExecutor 是一个简单的 JDBC 框架，只需要一个jar包足以。支持 Oracle, mySQL, HSQL, 和 PostgreSQL 等数据库，可轻易扩展支持新的数据库。

示例代码：

public static void testSimpleSelectWithParams()  {      String sql = "SELECT * FROM JDBC_TEST                             WHERE TEST_ID < ? AND TEST_DT < ?";      ConnectionPool conPool = new ConnectionPool(1, driverName,                                   conURL, username, password);      SQLExecutor sqlExec = new SQLExecutor(conPool);      sqlExec.addParam(new Integer(8));                 //add int param with value = 8      sqlExec.addParam(Date.valueOf("2003-05-10"));                 //add date param with value 5/10/03      SQLResults res = sqlExec.runQueryCloseCon(sql);                 //runs the query, closes connection      System.out.println(res.toString());                 //display entire result set in tabular form  }
