DBD :: Oracle和utf8

我在Solaris上的oracle 10数据库中插入UTF8字符串时遇到了一些麻烦,在perl v5.8.4上使用了最新的DBD :: Oracle。

这是我的数据库设置

这是我的perl $ dbh-> ora_nls_parameters()

$VAR1 = {
          'NLS_LANGUAGE' => 'AMERICAN',
          'NLS_TIME_TZ_FORMAT' => 'HH.MI.SSXFF AM TZR',
          'NLS_SORT' => 'BINARY',
          'NLS_NUMERIC_CHARACTERS' => '.,',
          'NLS_TIME_FORMAT' => 'HH.MI.SSXFF AM',
          'NLS_ISO_CURRENCY' => 'AMERICA',
          'NLS_COMP' => 'BINARY',
          'NLS_CALENDAR' => 'GREGORIAN',
          'NLS_DATE_FORMAT' => 'DD-MON-RR',
          'NLS_DATE_LANGUAGE' => 'AMERICAN',
          'NLS_TIMESTAMP_FORMAT' => 'DD-MON-RR HH.MI.SSXFF AM',
          'NLS_TERRITORY' => 'AMERICA',
          'NLS_LENGTH_SEMANTICS' => 'CHAR',
          'NLS_NCHAR_CHARACTERSET' => 'AL16UTF16',
          'NLS_DUAL_CURRENCY' => '$',
          'NLS_TIMESTAMP_TZ_FORMAT' => 'DD-MON-RR HH.MI.SSXFF AM TZR',
          'NLS_NCHAR_CONV_EXCP' => 'FALSE',
          'NLS_CHARACTERSET' => 'UTF8',
          'NLS_CURRENCY' => '$'
        };

在我的剧本中我有:

use utf-8;
$ENV{NLS_LANG}='AMERICAN_AMERICA.UTF8';
..
$sth->bind_param(5, $myclobfield, {ora_type => ORA_CLOB, ora_csform => SQLCS_NCHAR});
..

字符串在

上打印出1
print Encode::is_utf8($myclobfield);

但是像òàè这样的字符没有正确插入数据库。 (我使用符合utf8标准的客户端测试,可以正确插入和读取它们)

有人能建议最好的方法吗? 感谢

经过几个小时的锤击,并且篡改了所有的DBA,我解决了它:

我错过了这个:

 $ENV{NLS_NCHAR}='AL32UTF16';

也要小心

utf8::encode($myclobfield);

如果您不确定它是UTF8

干杯 -G。

Unicode文字需要以'n'为前缀,如下所示:

从双重选择n'Language - Språk - Język';
