查看t_tasks表中某日期的数据里 类型是order_view，状态是FINISH的内容，日期是输入参数。
CREATE OR REPLACE PROCEDURE put_task_id(sdate in date) IS taskid NUMBER(19); TYPE cur IS REF CURSOR; cur_01 cur; BEGIN DBMS_OUTPUT.ENABLE (buffer_size=>null);--设置缓冲区内存 OPEN cur_01 FOR SELECT t.id FROM t_tasks t WHERE t.type='order_view' AND t.status='FINISH' AND to_char(t.create_time)=sdate; LOOP FETCH cur_01 INTO taskid; EXIT WHEN cur_01%NOTFOUND; dbms_output.put_line(taskid); END LOOP; CLOSE cur_01; END; /调用存储过程
