oracle DBMS_LOCK.SLEEP()的使用

一

、執行 ORACLE_HOME/rdbms/admin/dbmslock.sql 来创建 dbms_lock;

-在DBA身分下grant execute on dbms_lock to USERNAME;

-執行測試代碼

begin
dbms_output.put_line(to_char(sysdate,'yyyymmddhh24miss'));
dbms_lock.sleep(60);
dbms_output.put_line(to_char(sysdate,'yyyymmddhh24miss'));
end;

二

1/创建测试表

CREATE TABLE tbl_tt (ID NUMBER(4),addtime DATE);

2/开始测试

BEGIN
   FOR i IN 1 .. 10
   LOOP
      INSERT INTO tbl_tt
           VALUES (i, SYSDATE);

      COMMIT;
      DBMS_LOCK.sleep (5);
   END LOOP;
END;
/

3/查询数据

        ID ADDTIME
