在做项目的过程中,经常需要调用数据库的存储过程,试着写了一下简单的例子,记录下。

存储过程(oracle):

    1) 无参存储过程

create or replace procedure firPro
  as 
  begin 
    dbms_output.put_line('Hello World!');
  end;

java调用:

public static void noPramPro()
    {
    	Connection con=DButil.getConnection(); 
    	try {
			CallableStatement stmt = con.prepareCall("{call firPro()}");
			stmt.execute();
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
    }

    2)有参存储过程:

create or replace procedure Ins_Pro
(stuNO in varchar,stuName in varchar,stuGender in varchar, 
stuAge in varchar,stuSeat in varchar, enrolldate in date,stuAddress in varchar,classNo in varchar)
as 
 begin 
   insert into student values(stuNO,stuName,stuGender,stuAge,stuSeat,enrolldate,stuAddress,classNo);
   commit;
  end;

java 调用:

public static void insertPro()
	{
		try {
			Connection con = DButil.getConnection();
			CallableStatement stmt = con.prepareCall("{call Ins_Pro(?,?,?,?,?,?,?,?)}");
			stmt.setString(1, "9");
			stmt.setString(2, "张三丰");
			stmt.setString(3, "男");
			stmt.setString(4, "90");
			stmt.setString(5, "55");
			stmt.setDate(6,  new Date(0));
			stmt.setString(7, "武当山");
			stmt.setString(8, "9");
			stmt.execute();
			
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}

     3)有输出的存储过程:

create or replace procedure selPro(stuNO in varchar,name out varchar,address out varchar)
as
  begin
   select stu_name,stu_address into name,address from student where stu_no = stuNO;
   end;

  java调用:

public static void selPro()
	{
		Connection con = DButil.getConnection();
		try {
			CallableStatement stmt = con.prepareCall("{call selPro(?,?,?)}");
			stmt.setString(1, "3");
			stmt.registerOutParameter(2, java.sql.Types.VARCHAR);
			stmt.registerOutParameter(3, java.sql.Types.VARCHAR);
			stmt.execute();
			String name =stmt.getString(2);
			String address = stmt.getString(3);
			System.out.println(name +"------"+address);
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}
