java读取oracle的存储过程

java读取oracle的存储过程(转 邢红瑞's blog) java读取oracle的存储过程网上的例子不少，都太简单，没有一个返回参考游标的,返回记录集，自己写一个怕日后忘了。 oracle的PLSQL CREATE OR REPLACE package chapter_13 as TYPE rs IS REF CURSOR ; procedure founder(oFields out rs); end; CREATE OR REPLACE package body chapter_13 as PROCEDURE founder(oFields out rs) IS BEGIN open oFields for select * from person; END founder; end; java代码 package jdbc; import java.io.*; import java.sql.*; import java.text.*; import oracle.jdbc.OracleTypes; public class TestStoredProcedures { Connection conn; public TestStoredProcedures() { try { DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); conn = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:orcl", "jola", "jola"); } catch (SQLException e) { System.err.println(e.getMessage()); e.printStackTrace(); } } public static void main(String[] args) throws Exception { new TestStoredProcedures().process(); } public void process() throws SQLException { long start = 0; long end = 0; CallableStatement cstmt = null; try { start = System.currentTimeMillis(); // *** SQL92 escape syntax *** cstmt = conn.prepareCall( "{call chapter_13.founder(?)}"); cstmt.registerOutParameter(1, OracleTypes.CURSOR); ResultSet rs = null; cstmt.execute(); rs = (ResultSet)cstmt.getObject(1); while (rs.next()) { System.out.println(rs.getString("NAME")); } rs.close(); end = System.currentTimeMillis(); System.out.println("Average elapsed time = " + (end - start) / 8 + " milliseconds"); } catch (SQLException e) { System.err.println("SQL Error: " + e.getMessage()); } finally { if (cstmt != null) { try { cstmt.close(); } catch (SQLException ignore) {} } } } protected void finalize() throws Throwable { if (conn != null) { try { conn.close(); } catch (SQLException ignore) {} } super.finalize(); } }
