1. 先创建一个FUNCTION
CREATE OR REPLACE FUNCTION GET_TIMEOUT_PROGRAM(i_customerNo IN TK_CUST_PROG_D.CUSTOM_NO%TYPE, i_programId IN TK_CUST_PROG_D.Prog_Id%TYPE, i_timeout IN TK_CUST_PROG_D.PROG_TIMEOUT%TYPE) RETURN number AS PRAGMA AUTONOMOUS_TRANSACTION; v_doresult NUMBER := 1; v_station SMALL_PROGRAM_STATUS.Station%TYPE; v_programId SMALL_PROGRAM_STATUS.Program_Id%TYPE; v_lastActiveTime date; v_spanMinutes NUMBER; BEGIN BEGIN SELECT Station, PROGRAM_ID, Last_Active_Time, floor(to_number(sysdate - LAST_ACTIVE_TIME) * 24 * 60) INTO v_station, v_programId, v_lastActiveTime, v_spanMinutes from SMALL_PROGRAM_STATUS WHERE STATION = i_customerNo AND PROGRAM_ID = i_programId AND floor(to_number(sysdate - LAST_ACTIVE_TIME) * 24 * 60) > i_timeout; EXCEPTION WHEN NO_DATA_FOUND THEN return 0; when TOO_MANY_ROWS then DBMS_OUTPUT.PUT_LINE('More than one record.'); END; merge into SMALL_PROGRAM_TASK t1 using (select i_customerNo as station, i_programId as program_id, 'N' send_flag from dual) t2 on (t1.station = t2.station and t1.program_id = t2.program_id and t1.send_flag = t2.send_flag) when matched then update set t1.last_active_time = v_lastActiveTime, t1.program_timeout = i_timeout, t1.expired_time = v_spanMinutes, t1.modify_date = sysdate() when not matched then insert (job_no, station, program_id, last_active_time, send_flag, program_timeout, create_date, expired_time) values (sys_guid(), v_station, v_programId, v_lastActiveTime, 'N', i_timeout, sysdate(), v_spanMinutes); commit; DBMS_OUTPUT.PUT_LINE('v_doresult=' || v_doresult); DBMS_OUTPUT.PUT_LINE('v_station=' || v_station); DBMS_OUTPUT.PUT_LINE('v_spanMinutes=' || v_spanMinutes); RETURN v_doresult; END;
2. 创建procedure
CREATE OR REPLACE PROCEDURE get_expired_program AS v_timeout TK_CUST_PROG_D.PROG_TIMEOUT%TYPE; v_customerNo TK_CUST_PROG_D.CUSTOM_NO%TYPE; v_programId TK_CUST_PROG_D.Prog_Id%TYPE; v_doresult number; v_records_sum number := 0; CURSOR c_cursor IS SELECT CUSTOM_NO,Prog_Id,PROG_TIMEOUT FROM TK_CUST_PROG_D WHERE MONITOR_PROGRAM='Y'; BEGIN OPEN c_cursor; LOOP FETCH c_cursor INTO v_customerNo,v_programId,v_timeout; EXIT WHEN c_cursor%NOTFOUND; begin select GET_TIMEOUT_PROGRAM(v_customerNo,v_programId,v_timeout) into v_doresult from dual; v_records_sum := v_doresult; end; END LOOP; dbms_output.put_line('records_num: "' || v_records_sum || '"'); CLOSE c_cursor; END;
3.创建调用定时排程调用这个Procedure,每五分钟调用一次procedure
begin sys.dbms_scheduler.create_job(job_name => 'PLOEC.GET_EXPIRED_PROGRAM_TASK', job_type => 'STORED_PROCEDURE', job_action => 'get_expired_program', start_date => to_date('06-03-2017 00:00:00', 'dd-mm-yyyy hh24:mi:ss'), repeat_interval => 'Freq=Minutely;Interval=5', end_date => to_date('07-03-2049 00:00:00', 'dd-mm-yyyy hh24:mi:ss'), job_class => 'DBMS_JOB$', enabled => true, auto_drop => false, comments => '每五分鐘掃呼叫get_expired_program一次'); end; /
Function或者Procedure在compile时候出错,可以通过以下SQL查看errors detail
show errors function GET_TIMEOUT_PROGRAM; show errors procedure get_expired_program;
Call Procedure
exec get_expired_program;
Test Function
declare outNumber number; begin select GET_TIMEOUT_PROGRAM('TPE','P0001',90) into outNumber from dual; dbms_output.put_line('outNumber: "' || outNumber || '"'); end;
