oracle常用知识随笔

1、创建表空间及用户赋权

create tablespace spaceone 
datafile '/dev/spaceone'
size 80m
extent management local
segment space management auto
/

extent management local
segment space management auto 用法：

（1）如果file 已经存在，并且在创建时指定了file size，那么就重用原文件，并应用新的size，如果没有指定file size，则保留原有的大小

（2）如果file 不存在，oracle 将忽略该参数

（3）如果Oracle 使用了已经存在的file，那么之前file里的数据将全部丢失

2、创建用户及赋权

set serveroutput on;
set feedback off;
set term off;
set linesize 200;
set define on;
clear screen;

declare
susername varchar2(100):=nvl('&1','report');
spassword varchar2(100):=nvl('&2','report');
v_count number;
i_l_9i number;
i_l_count integer;
i_l_countl integer;
str_l_key varchar2(300):='schema_name';
str_l_schema varchar2(300):=upper(susername);
i_l_count3 integer;
i_l_count4 integer;

begin
select count(1)
into v_count
from dba_users
where username=upper(susername)

if v_count > 0 then
execute immediate 'drop user'||susername||'cascade';

select count(*) into i_l_9i from v$version where banner like '%9.%';

select count(*) into i_l_count from user_tables t where t.table_name ='T_REPORT_SCHEMA';

if (i_l_9i=0) then
execute immediate 'grant select on v_$sga_dynamic_components to'||susername;
end if;

if (i_l_9i=0) then
execute immediate 'begin dbms_stats.delete_system_stats() end';
execute immediate 'begin dbms_stats.set_system_stats(upper(''CPUSPEEDNW''),1840) end'
end if;

if (i_l_count=0) then
execute immediate 'create table T_REPORT_SCHEMA(KEY varchar2(500) not null,
