oracle session NLS_LANGUAGE

以下代码可以加在程序包里面，用于修改当前session的语言参数。

--设置session语言    PROCEDURE p_Set_Nls_Language(Pi_Nls_Lang IN VARCHAR2 DEFAULT 'SIMPLIFIED CHINESE') IS    BEGIN        EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_LANGUAGE=' || Chr(39) ||                          Pi_Nls_Lang || Chr(39);    EXCEPTION        WHEN OTHERS THEN            EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_LANGUAGE=' || Chr(39) ||                              'SIMPLIFIED CHINESE' || Chr(39);    END p_Set_Nls_Language;

一般常用'SIMPLIFIED CHINESE' 和'AMERICAN'
