修改oracle編碼格式

文章參照：https://www.jb51.net/article/53078.htm

1.查看oracle當前編碼格式：

   
   
  
  
          
 
           
 
            
 
             
 
            
 
            
 
             
 
              SELECT * 
              FROM V$NLS_PARAMETERS 
              WHERE PARAMETER = 
              'NLS_CHARACTERSET' ; 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             
 
              SELECT USERENV( 
              'language') 
              FROM DUAL; 
             
 
            
 
          
  
  
 
 
         

   NLS_CHARACTERSET    AL32UTF8   

   SIMPLIFIED CHINESE_CHINA.AL32UTF8 

2.以sysdba身份登錄

3.關閉數據庫 shutdown immediate;

4.以mount打來數據庫，startup mount

5.設置session

   
   
  
  
          
 
           
 
            
 
             
 
            
 
            
 
             

               SQL> 
              ALTER 
              SYSTEM 
              ENABLE 
              RESTRICTED 
              SESSION; 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               SQL> 
              ALTER 
              SYSTEM 
              SET JOB_QUEUE_PROCESSES= 
              0; 
             
 
            
 
           
 
            
 
             
 
            
 
            
 
             

               SQL> 
              ALTER 
              SYSTEM 
              SET AQ_TM_PROCESSES= 
              0; 
             
 
            
 
          
  
  
 
 
         

6.啟動數據庫

alter database open;

7.修改字符集

ALTER DATABASE CHARACTER SET ZHS16GBK;

提示我們的字符集：新字符集必須為舊字符集的超集:

ALTER DATABASE character set INTERNAL_USE ZHS16GBK;

8.關閉，重新啟動

shutdown immediate;

startup
