如何将Oracle数据库中的UTF-8格式数据转换为文本文件

如何将UTF-8格式的数据从Oracle数据库转换为文本文件,所有UTF-8字符都正确输出,例如中文字符.

我试图从启用了UTF-8的Oracle数据库假脱机数据并尝试将相同的数据假脱机到txt或cvs.而不是我得到的汉字????.

我知道这个问题早先被问过,但没有给出答案,因此再次重新提出这个问题.

批量程序：

sqlplus snprn/SpotProd_07@SPOTDEV_VM.WORLD @C:BatchJobSPOTReportspotreport.SQL

rem sqlplus snprn/SpotProd_07@lprodspot @C:BatchJobSPOTReportspotreportrecovery.SQL

rem copy Spot_Item_details*.* C:BatchJobSPOTReport /y
copy Spot_Item_details*.* C:BatchJobSPOTReport /y
rem xcopy Spot_Item_details*.* backup /y
rem del Spot_Item_details*.*

SQL代码：

SET HEADING ON
SET FEEDBACK    OFF
SET ECHO    OFF
SET LINESIZE    5000
SET PAGESIZE    0
SET TRIMS   ON
SET ARRAYSIZE   5


COLUMN extract_date NEW_VALUE _date
SELECT TO_CHAR(SYSDATE,'RRRRMMDD') extract_date 
FROM   DUAL;

SPOOL D:SPOT2BatchJobSPOTReportSpot_Item_details_daily_&_Date.txt

解决方法

正如您在以下示例中所看到的,查询输出的内容取决于客户端的NLS_LANG设置.

C:&;set NLS_LANG=.US7ASCII
C:&;sqlplus ???/???@xe

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 3 09:31:32 2010
> select chr(193) from dual;

C
-
?

> quit

C:&;set NLS_LANG=.AL32UTF8
C:&;sqlplus ???/???@xe

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 3 09:31:49 2010
> select chr(193) from dual;

C
-
┴

如果您的客户端是Windows,请尝试以上操作.如果它是unix(ish)平台,请尝试

export NLS_LANG=.AL32UTF8
