在ORACLE存储过程中创建临时表

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

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。

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

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('′?è?μ?2?êy′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_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

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'))
