Oracle11g 合并和修剪功能

我正在尝试执行下面的脚本

CREATE VIEW JOES.WEBSKULOOKUPVIEW (

                         WPROD.H1SCNS = WPSTYLE.H2SCNS AND  
                        WPSTYLE.H2SCNS = WPSKU.H3SCNS AND

                        ESKU.SKUID = SKUSIZE.SKUID AND SKUACTIVESTATUS NOT IN ('P', 'D') ;

它抛出如下所述的错误

(COALESCE(TRIM(FIRSTSIZE.SHORTSCALEVALUE) , '') || COALESCE(TRIM(', ' || SECSIZE.SHORTSCALEVALUE), '')) AS "SIZE",
                                                                                    *
ERROR at line 20:
ORA-12704: character set mismatch

但这就是合并和修剪的语法

那么我应该做哪些可能的更改来解决这个问题。

看起来像是重复的，谢谢，我以前没有检查过这篇文章。现在很好用
