创建触发器

create or replace

TRIGGER "MYXNH".triger_transfer_id    before insert on t_transfer for each row    

begin        if :new.transfer_id is null then            select TRANSFER_SEQ.nextval into :new.transfer_id from dual;        

end if;    end;

 

create or replace

TRIGGER "MYXNH"."TRIGGER_JRNL_DETAL_ID" before insert on T_JRNL_DETAIL    for each row begin     if inserting then       if :NEW."ID" is null then        select JRNL_DETAL_SEQ.nextval into :NEW."ID" from dual;       end if;    end if; end;

　2. 导出一个完整数据库

　　exp system/manager file=c:\bible_db log=c:\dible_db full=y

　　3. 导出数据库定义而不导出数据

　　exp system/manager file=bible_db log=dible_db full=y rows=n

　　4. 导出一个或一组指定用户所属的全部表、索引和其他对象

　　exp system/manager file=seapark log=seapark owner=seapark

　　exp system/manager file=seapark log=seapark owner=(seapark,amy,amyc,harold)

 

 

 

 

 

 

1.设置页面显示总行数

 

show pagesize;   //首先查看目前的pagesize,默认是14

 

set pagesize 100; //将pagesize设置好100,则可以一次显示够多行记录了

 

2.设置行的宽度

 

show linesize;   //查看目前的linesize,默认是80

 

set linesize 100; //设置成100或者更宽都可以

查看连接客户端

 

 select t.MACHINE,t.OSUSER,t.PROGRAM,t.LOGON_TIME,t.USERNAME ,t.STATUS from v$session t  order by t.LOGON_TIME desc;

 

 select b.sql_text 

from v$session a,v$sqlarea b 

where a.sql_hashvalue=b.hash_value and a.sid=100

修改oracle 10g的字符集

Posted on 2006-10-16 in Oracle | 2 Comments ? Trackback URI

修改数据库字符集为：ZHS16GBK

查看服务器端字符集

SQL > select * from V$NLS_PARAMETERS

修改：

$sqlplus /nolog

SQL>conn / as sysdba?

若此时数据库服务器已启动，则先执行 SHUTDOWN IMMEDIATE 命

令关闭数据库服务器，然后执行以下命令:

SQL>shutdown immediate?

SQL>STARTUP MOUNT?

SQL>ALTER SYSTEM ENABLE RESTRICTED SESSION?

SQL>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0?

SQL>ALTER SYSTEM SET AQ_TM_PROCESSES=0?

SQL>ALTER DATABASE OPEN?

SQL>ALTER DATABASE CHARACTER SET ZHS16GBK?

*

ERROR at line 1:

ORA-12721: operation cannot execute when other sessions are active

若出现上面的错误，使用下面的办法进行修改，使用INTERNAL_USE可以跳过超集的检查：

SQL>ALTER DATABASE CHARACTER SET INTERNAL_USE ZHS16GBK?

SQL>SHUTDOWN IMMEDIATE?

SQL>STARTUP

 

 

 

 

 

 

 

select * from v$logfile;

 

select Tablespace_Name,Sum(bytes)/1024/1024 From Dba_Segments Group By Tabl espace_Name;

 

 

 

select * from v$log  可以看出日志文件的大小
