oracle中使用ddl语言
在ORACLE存储过程中创建临时表
Java代码
create or replace procedure select_look
as
str varchar2(100);
begin
str:='select * from emp';
execute immediate str;
end;
在ORACLE存储过程中创建临时表
2007年11月15日 星期四 14:27
Java代码
create procedure pro
as
str varchar2(100);
begin
str:='CREATE GLOBAL TEMPORARY TABLE TABLENAME (
COL1 VARCHAR2(10),
COL2 NUMBER
) ON COMMIT PRESERVE ROWS' ;
execute immediate str; --使用动态SQL语句来执行
end;
/
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。
Java代码
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; ----使用动态SQL语句来执行
str:='insert into SETT_DAILYTEST (select naccountid,nsubaccountid from sett_dailyaccountbalance)';
execute immediate str;
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
Java代码
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('???????????í?ó');
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
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;
END IF;
END PR_DAILYCHECK;
oracel 日期函数
Java代码
to_date(substr(ildgl,2,6),'rrDDD')
insert into scott.f42111 values('mike',600,to_date('2009-04-17 10:17:00','yyyy-mm-dd hh24:mi:ss'))
