Oracle 中統計時間間隔的方法

1. using DBMS_UTILITY.GET_TIME

s_date pls_ineteger;

ln_interval pls_integer :=0;

 

s_date := DBMS_UTILITY.GET_TIME;

--do something

ln_interval := ln_interval + (DBMS_UTILITY.GET_TIME-s_date);

--some other things

--ouput interval

DBMS_OUTPUT.PUT_LINE('time=: ' || ln_interval/100 || ' sec');

 

2. using systimestamp

s_date timestamp;

temp varchar2(1000);

 

s_date:=systimestamp;

--do something

temp := systimestamp-s_date;

DBMS_OUTPUT.PUT_LINE('time=: ' || temp);
