查詢oracle的字符集
方法一
sql> select userenv(』language』) from dual;
userenv(』language』)
—————————————————-
american_america.we8iso8859p1

sql> select * from v$nls_parameters;
parameter value
—————————————————————- —————————————————————-
nls_language american
nls_territory america
nls_currency $
nls_iso_currency america
nls_numeric_characters .,
nls_calendar gregorian
nls_date_format dd-mon-rr
nls_date_language american
nls_characterset we8iso8859p1
nls_sort binary
nls_time_format hh.mi.ssxff am
nls_timestamp_format dd-mon-rr hh.mi.ssxff am
nls_time_tz_format hh.mi.ssxff am tzr
nls_timestamp_tz_format dd-mon-rr hh.mi.ssxff am tzr
nls_dual_currency $
nls_nchar_characterset al16utf16
nls_comp binary
nls_length_semantics byte
nls_nchar_conv_excp false
修改字符集
connect system/oracle10g as sysdba;
update props$ set value$=』utf8′ where name=』nls_characterset』;
shutdown immediate;
startup mount;
alter system enable restricted session ;
alter system set job_queue_processes=0;
alter system set aq_tm_processes=0;
alter database open;
alter database character set internal_use utf8;
alter database national character set internal_use utf8;
shutdown immediate;
startup;
