一、pl/sql developer 中文字段显示乱码
原因:因为数据库的编号格式和pl /sql developer的编码格式不统一造成的。
二、查看和修改oracle数据库字符集:
select userenv('language') from dual;
查询结果:
SIMPLIFIED CHINESE_CHINA.AL32UTF8
--修改oracle数据库字符集:(在SQL Plus中)
sql> conn / as sysdba;
sql> shutdown immediate;
database closed.
database dismounted.
oracle instance shut down.
sql> startup mount;
oracle instance started.
total system global area 135337420 bytes
fixed size 452044 bytes
variable size 109051904 bytes
database buffers 25165824 bytes
redo buffers 667648 bytes
database mounted.
sql> alter system enable restricted session;
system altered.
sql> alter system set job_queue_processes=0;
system altered.
sql> alter system set aq_tm_processes=0;
system altered.
sql> alter database open;
database altered.
sql> alter database character set internal_use JA16SJIS;
sql> shutdown immediate;
sql> startup;
三、修改pl/sql developer 的编码格式:
在windows中创 建一个名为“NLS_LANG”的系统环境变量,设置其值为“SIMPLIFIED CHINESE_CHINA.ZHS16GBK”,
然后重新启动 pl/sql developer,这样检索出来的中文内容就不会是乱码了。如果想转换为UTF8字符集,可以赋予“NLS_LANG”为 “AMERICAN_AMERICA.UTF8”,然后重新启动 pl/sql developer。其它字符集设置同上。
