Oracle学习-存储过程及调用

写了存储过程就必须会调用，不然用来干嘛勒

存储过程--查询用户姓名，年龄，月薪

create or replace procedure queryuserinfo(pid in number,pname out VARCHAR2,page out NUMBER,pmoney out VARCHAR2)
as
begin
select name,age,money into pname,page,pmoney from tb_user where id = pid;
end;

Oracle连接--JDBCUtil

package jdbc.utils;

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

public class JDBCUtils {
private static String driver = "oracle.jdbc.OracleDriver";
private static String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";
private static String user = "xhs";
private static String password = "123456";
// 注册数据库的驱动
static {
try {
Class.forName(driver);
} catch (ClassNotFoundException e) {
throw new ExceptionInInitializerError(e);
}
}

// 获取数据库连接
public static Connection getConn() {
try {
return DriverManager.getConnection(url, user, password);
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}

// 释放数据库资源
public static void release(Connection conn, Statement st, ResultSet rs) {
if (rs != null) {
try {
rs.close();
} catch (SQLException e) {
e.printStackTrace();
} finally {
rs = null;
}
}
if (st != null) {
try {
st.close();
} catch (SQLException e) {
e.printStackTrace();
} finally {
st = null;
}
}
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
} finally {
conn = null;
}
}
}
}

调用：

package jdbc.test;

import java.sql.CallableStatement;
import java.sql.Connection;

import org.junit.Test;

import jdbc.utils.JDBCUtils;
import oracle.jdbc.driver.OracleTypes;

public class testProcedure {
@Test
public void testUserProcedure(){
String sql = "{call queryuserinfo(?,?,?,?)}";
Connection conn=null;
CallableStatement call =null;
try {
conn=JDBCUtils.getConn();
call=conn.prepareCall(sql);
call.setInt(1, 25);
call.registerOutParameter(2, OracleTypes.VARCHAR);
call.registerOutParameter(3, OracleTypes.NUMBER);
call.registerOutParameter(4, OracleTypes.VARCHAR);
call.execute();
String name = call.getString(2);
String age = call.getString(3);
String money = call.getString(4);
System.out.println(name+"的年龄是"+age+"月薪是"+money);
} catch (Exception e) {
e.printStackTrace();
}finally{
JDBCUtils.release(conn, call, null);
}
}
}
