作為程式語言中的三大基本邏輯之一的迴圈，這次在我的專案開發中也用到了不少，但是有乙個問題不知道是不是蠻長時間沒有使用導致，要用到的時候，不能第一時間完整地寫出，也許是生疏了，也也許是之前為了方便都是從以前的筆記ctrl+v的緣故吧。
for i in (1...100) loop
//迴圈語句
end loo;
其實就相當於 for(int i=0;i<100;i++)
for k in (select ra2.levelno，rownum + 8 ordernum
from (select
distinct cl.levelno
from pdm_ylzj_crutoqualinspe c
--只選擇合併後的資料
inner
join pdm_ylzj_crutoqualsumsheetd sd on sd.pdm_ylzj_crutoqualinspeid =
c.pdm_ylzj_crutoqualinspeid

join pdm_ylzj_crutolevelstruc cl on cl.pdm_ylzj_crutoqualinspeid =
c.pdm_ylzj_crutosendinspeid

join pdm_ylzj_recrutoqualinspe fj on fj.inspectionno = c.inspectionno

and cl.leveltype = '2'
and c.provincesno = p_province
and instr(decode(p_yearno, '', c.yearno, p_yearno), c.yearno) > 0
order
by cl.levelno asc) ra2)

v_tmpdiff2ratio := f_getstrutslvlweightratio(p_cigatype, p_yearno, p_projtype, p_level, p_part,
p_grade, p_way, p_inspeuser, p_inspedatestart,
p_inspedateend, p_province, p_city, p_country,
p_isqualify, i.purchaselevel, k.levelno, '2');
v_upd2diff2sql := 'update dynatempdata dd set t' || k.ordernum || '=''' || v_tmpdiff2ratio ||
'''where dd.dynatempdataid=''' || v_row2guid || '''
and dd.conditionid=''' ||
p_conditionid || '''';
execute immediate v_upd2diff2sql;
end loop;
create
or replace procedure
p_cursor_employee
isemprows
employees%rowtype;
cursor emprows is
select * from employees;
begin
for emprows in emprows loop
dbms_output.put_line(emprows.employeeid||』,'||emprows.name||』,'||emprows%rowcount);
endloop;
end p_cursor_employee;
while i<100
loop
i :=i+2;
endloop;
create

number;
begin
i := 0;

exit when(i > 10);

endloop;
end;
當i>10 時退出迴圈，否則一直執行
