在ORACLE存儲(chǔ)過(guò)程中創(chuàng)建臨時(shí)表

存儲(chǔ)過(guò)程里不能直接使用DDL語(yǔ)句，所以只能使用動(dòng)態(tài)SQL語(yǔ)句來(lái)執(zhí)行

--ON COMMIT DELETE ROWS 說(shuō)明臨時(shí)表是事務(wù)指定，每次提交后ORACLE將截?cái)啾恚▌h除全部行）
--ON COMMIT PRESERVE ROWS 說(shuō)明臨時(shí)表是會(huì)話指定，當(dāng)中斷會(huì)話時(shí)ORACLE將截?cái)啾怼?/p>

CREATE OR REPLACE PROCEDURE temptest
(p_searchDate IN DATE)
IS
v_count INT;
str varchar2(300);
BEGIN
v_count := 0;
str:='drop table SETT_DAILYTEST';
execute immediate str;
str:='CREATE GLOBAL TEMPORARY TABLE SETT_DAILYTEST (
NACCOUNTID NUMBER not null,
NSUBACCOUNTID NUMBER not null)
ON COMMIT PRESERVE ROWS';
execute immediate str; ----使用動(dòng)態(tài)SQL語(yǔ)句來(lái)執(zhí)行
str:='insert into SETT_DAILYTEST (select naccountid,nsubaccountid from sett_dailyaccountbalance)';
execute immediate str;
END temptest;

上面建立一個(gè)臨時(shí)表的存儲(chǔ)過(guò)程

下面是執(zhí)行一些操作,向臨時(shí)表寫數(shù)據(jù)。

CREATE OR REPLACE PROCEDURE PR_DAILYCHECK
(
p_Date IN DATE,
p_Office IN INTEGER,
p_Currency IN INTEGER,
P_Check IN INTEGER,
p_countNum OUT INTEGER)
IS
v_count INT;
BEGIN
v_count := 0;
IF p_Date IS NULL THEN
dbms_output.put_line('日期不能為空');
ELSE
IF P_Check = 1 THEN
insert into SETT_DAILYTEST (select naccountid,nsubaccountid from sett_dailyaccountbalance
where dtdate = p_Date);
select
count(sd.naccountid) into v_count
from sett_subaccount ss,sett_account sa,sett_dailytest sd
where sd.naccountid = sa.id and sd.nsubaccountid = ss.id and sa.id = ss.naccountid
AND sa.nofficeid = p_Office AND sa.ncurrencyid = p_Currency
and rownum < 2;
COMMIT;
p_countNum := v_count;
dbms_output.put_line(p_countNum);
END IF;
IF P_Check = 2 THEN
insert into SETT_DAILYTEST (select naccountid,nsubaccountid from sett_dailyaccountbalance

select
