Java 调用Oracle存储过程

Java调用Oracle存储过程一：
先创建一张表，操作如下，我是从plsql里面创建的：

-- Create table
create table B_ID
(
  I_ID   VARCHAR2(200),
  I_NAME VARCHAR2(200)
)
tablespace USERS
  pctfree 10
  initrans 1
  maxtrans 255
  storage
  (
    initial 64
    minextents 1
    maxextents unlimited
  );

这上面实际就是建立两个字段就可以了，我是从plsql里面拷贝出来的语句：
下面建立存储过程：

create or replace procedure TESTA(PARA1 IN VARCHAR2,PARA2 IN VARCHAR2) is
begin
  INSERT INTO zhang.B_ID (I_ID,I_NAME) VALUES (PARA1, PARA2); 
end TESTA;

下面是Java调用代码：

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:orcl";
		Statement stmt = null;
		ResultSet rs = null;
		Connection conn = null;
		CallableStatement cstmt = null;

		try {
			Class.forName(driver);
			conn = DriverManager.getConnection(strUrl, "zhang", "zhang");
			CallableStatement proc = null;
			proc = conn.prepareCall("{ call zhang.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();
					}
					if (conn != null) {
						conn.close();
					}
				}
			} catch (SQLException ex1) {
			}
		}
	}
}

第二种：Java调用存储过程：
首先建立表：

-- Create table
create table TESTTB
(
  I_ID   VARCHAR2(300),
  I_NAME VARCHAR2(300)
)
tablespace USERS
  pctfree 10
  initrans 1
  maxtrans 255
  storage
  (
    initial 64
    minextents 1
    maxextents unlimited
  );

表里面需要，为I_ID插入100，I_NAME随便，我这里插入的是100kb，因为下面的java代码要根据I_ID=100来查找I_Name，最终在控制台输出的是：100kb，就说明你成功啦。

建立触发器：

create or replace procedure TESTB(PARA1 IN VARCHAR2,PARA2 OUT VARCHAR2) is
begin
  SELECT I_NAME INTO PARA2 FROM zhang.TESTTB WHERE I_ID= PARA1; 
end TESTB;

Java代码：

package com.hyq.src;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Types;

public class TestProcedureTWO {
	public TestProcedureTWO() {
	}

	public static void main(String[] args) {
		String driver = "oracle.jdbc.driver.OracleDriver";
		String strUrl = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";
		Statement stmt = null;
		ResultSet rs = null;
		Connection conn = null;
		try {
			Class.forName(driver);
			conn = DriverManager.getConnection(strUrl, "zhang", "zhang");
			CallableStatement proc = null;
			proc = conn.prepareCall("{ call zhang.TESTB(?,?) }");
			proc.setString(1, "100");
			proc.registerOutParameter(2, Types.VARCHAR);
			proc.execute();
			String testPrint = proc.getString(2);
			System.out.println("=testPrint=is=" + testPrint);
		} catch (SQLException ex2) {
			ex2.printStackTrace();
		} catch (Exception ex2) {
			ex2.printStackTrace();
		} finally {
			try {
				if (rs != null) {
					rs.close();
					if (stmt != null) {
						stmt.close();
					}
					if (conn != null) {
						conn.close();
					}
				}
			} catch (SQLException ex1) {
			}
		}
	}
}

第三种Java调用存储过程：
先建立包，我使用plsql来建立的包

CREATE OR REPLACE PACKAGE TESTPACKAGE AS
TYPE Test_CURSOR IS REF CURSOR;
end TESTPACKAGE;

下面建立触发器：

create or replace procedure TESTC(p_CURSOR out TESTPACKAGE.Test_CURSOR) is
begin
  OPEN p_CURSOR FOR SELECT * FROM ZHANG.TESTTB; 
end TESTC;

Java代用代码：

package com.hyq.src;

import java.sql.*;
import java.io.OutputStream;
import java.io.Writer;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import oracle.jdbc.driver.*;

public class TestProcedureTHREE {
	public TestProcedureTHREE() {
	}

	public static void main(String[] args) throws Exception {
		String driver = "oracle.jdbc.driver.OracleDriver";
		String strUrl = "jdbc:oracle:thin:@localhost:1521:orcl";
		Statement stmt = null;
		ResultSet rs = null;
		Connection conn = null;

		try {
			Class.forName(driver);
			conn = DriverManager.getConnection(strUrl, "zhang", "zhang");

			CallableStatement proc = null;
			proc = conn.prepareCall("{ call zhang.testc(?) }");
			proc.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);
			proc.execute();
			rs = (ResultSet) proc.getObject(1);

			while (rs.next()) {
				System.out.println("" + rs.getString(1) + "" + rs.getString(2)
						+ "");
			}
		} catch (SQLException ex2) {
			ex2.printStackTrace();
		} catch (Exception ex2) {
			ex2.printStackTrace();
		} finally {
			try {
				if (rs != null) {
					rs.close();
					if (stmt != null) {
						stmt.close();
					}
					if (conn != null) {
						conn.close();
					}
				}
			} catch (SQLException ex1) {
				ex1.printStackTrace();
			}
		}
	}
}
