java 调用 oracle 存储过程

java 调用 oracle 存储过程三个实例（看前知识，需要存储过程，jdbc相关一点点）

1.插入，无返回值

oracle 的 procedure 为

create or replace procedure add_project(proid      varchar2,
                                        proversion number,
                                        proname    varchar2,
                                        customID varchar2 default null) is
begin
  insert into T_LPROMIS_XMGL_GBBXMXX pro
    (xmid, xmbbh, xmmc,pro.khid)
  values
    (proid, proversion, proname,customID);
end;

 

2.查询，有一个out varchar的返回值

oracle 的 procedure 为

create or replace procedure query_project
(proname in varchar2, proid out varchar2)
is 
begin
  select pro.xmid into proid from T_LPROMIS_XMGL_GBBXMXX pro
where pro.xmmc = proname;
end;

 

3.查询，有一个out ref cursor的返回值

oracle 的 procedure 为

create or replace package query_project_pck
as 
type pro_ref_cursor_type is ref cursor;
type pro_table is table of varchar(100);
type pro_record is record(name varchar(100),id varchar(100));
procedure pro_procedure(name varchar,id varchar);
end query_project_pck; -- define package

create or replace procedure query_pro(pro_result out query_project_pck.pro_ref_cursor_type) is
begin
  open pro_result for
    select pro.xmid, pro.xmmc,pro.updatetime from T_LPROMIS_XMGL_GBBXMXX pro return pro_record_type;
end; --create procedure using ref cursor

 

以上为oracle数据库

下面就是jdbc call procedure 了，上代码：

public static void test() throws ClassNotFoundException, SQLException{
		System.out.println("=====Test.test=====");
		Class.forName("oracle.jdbc.driver.OracleDriver");
		Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.32.227:1521:orcl","use","password");
		//Connection conn = new Conn().getConnection();
		CallableStatement cstmt = null;
		ResultSet rs = null;
		try{
			
			// 过程调用，无返回值
			cstmt = conn.prepareCall("call add_project(?,?,?)");
			cstmt.setString(1,"testproject1");
			cstmt.setInt(2, 0);
			cstmt.setString(3, "super man project");
			cstmt.execute();
			cstmt.setString(1, "testproject2");
			cstmt.setInt(2, 0);
			cstmt.setString(3, "a worker project");
			cstmt.execute();
			cstmt.setString(1, "testproject3");
			cstmt.setInt(2, 0);
			cstmt.setString(3, "a user project");
			cstmt.execute();
			System.out.println("插入成功");
			
			cstmt = conn.prepareCall("call query_project(?,?)");
			cstmt.registerOutParameter(2,Types.VARCHAR);
			cstmt.setString(1, "项目");
			cstmt.execute();
			System.out.println(cstmt.getString(2));
			cstmt = conn.prepareCall("call query_pro(?)");
			cstmt.registerOutParameter(1, OracleTypes.CURSOR);
			cstmt.execute();
			rs = (ResultSet) cstmt.getObject(1);
			while(rs.next())
			{
				
				System.out.println("id= "+rs.getString(1));
				System.out.println("name="+rs.getString(2));
				System.out.println("msg="+rs.getString(3));
			}
			
			if(!rs.isClosed())
				rs.close();
			cstmt.close();
			conn.close();
		}catch(Exception e){
			System.out.println("=====Test.test=====\n操作失败");
			e.printStackTrace();
		}
	}
