在ORACLE存储过程中创建临时表

存储过程里不能直接使用DDL语句，所以只能使用动态SQL语句来执行

--ON COMMIT DELETE ROWS 说明临时表是事务指定，每次提交后ORACLE将截断表（删除全部行）
--ON COMMIT PRESERVE ROWS 说明临时表是会话指定，当中断会话时ORACLE将截断表。

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; ----使用动态SQL语句来执行删除表
str:='CREATE GLOBAL TEMPORARY TABLE SETT_DAILYTEST ( NACCOUNTID NUMBER not null, NSUBACCOUNTID NUMBER not null) ON COMMIT PRESERVE ROWS';
execute immediate str; ----使用动态SQL语句来执行新建表
str:='insert into SETT_DAILYTEST (select naccountid,nsubaccountid from sett_dailyaccountbalance)';
execute immediate str; ----使用动态SQL语句来执行插入数据
END temptest;

上面建立一个临时表的存储过程

下面是执行一些操作,向临时表写数据。

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('日期不能为空');
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 where dtdate = p_Date);
select
count(sd.naccountid) into v_count
from sett_cfsubaccount ss,sett_account sa,sett_dailytest sd

and rownum < 2;
COMMIT;
p_countNum := v_count;
dbms_output.put_line(p_countNum);
END IF;
END IF;
END PR_DAILYCHECK;
