用java调用oracle存储过程总结

声明：
以下的例子不一定正确，只是为了演示大概的流程。
一：无返回值的存储过程
存储过程为：
CREATE OR REPLACE PROCEDURE TESTA(PARA1 IN VARCHAR2,PARA2 IN VARCHAR2)  AS
BEGIN
   INSERT INTO HYQ.B_ID (I_ID,I_NAME) VALUES (PARA1, PARA2);
END TESTA;
然后呢，在java里调用时就用下面的代码：
package com.hyq.src;
 
import java.sql.*;
import java.sql.ResultSet;
 
public class TestProcedureOne {
  public TestProcedureOne() {
  }
  public static void main(String[] args ){
    String driver = "oracle.jdbc.driver.OracleDriver";
    String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521: hyq ";
    Statement stmt = null;
    ResultSet rs = null;
    Connection conn = null;
    CallableStatement cstmt = null;
 
    try {
      Class.forName(driver);
      conn =  DriverManager.getConnection(strUrl, " hyq ", " hyq ");
      CallableStatement proc = null;
      proc = conn.prepareCall("{ call HYQ.TESTA(?,?) }");
      proc.setString(1, "100");
      proc.setString(2, "TestOne");
      proc.execute();
    }
    catch (SQLException ex2) {
      ex2.printStackTrace();
    }
    catch (Exception ex2) {
      ex2.printStackTrace();
    }
    finally{
      try {
        if(rs != null){
          rs.close();
          if(stmt!=null){
            stmt.close();
