我编写了以下代码来根据用户 NLS_LANGUAGE 变量获取日期。我正在 Oracle Fusion 内置的 BI Publisher 中编写此代码，但我怀疑它是否重要。我已经看到它适用于美国人、西班牙人等，但同样不适用于法语或巴西葡萄牙语。该start_time字段的类型为TIMESTAMP。当我硬编码巴西葡萄牙语而不是动态代码时，它适用于 tr.start_time。但是当我使用动态代码时，就会出现这个问题。此外，如果我用 sysdate 替换 tr.start_time，那么它也可以工作。我收到以下错误：
ORA-01877 string too long for the internal buffer
请让我知道我哪里出错了。
WITH nls AS (
SELECT 'NLS_DATE_LANGUAGE = '''||value||'''' value
FROM v$nls_parameters
WHERE parameter = 'NLS_LANGUAGE')
SELECT TO_CHAR(tr.start_time,'Day,DD Mon YYYY',nls.value) date_from
FROM table_list
我也试过：
WITH nls AS
(SELECT value
FROM v$nls_parameters
WHERE parameter = 'NLS_LANGUAGE')
select
TO_CHAR(tr.start_time,'Day,DD Mon YYYY','NLS_DATE_LANGUAGE='''||nls.value||'''') date_from
FROM table_list
下面的代码也不起作用：
SELECT TO_CHAR(systimestamp ,'Day,DD Mon YYYY', 'NLS_DATE_LANGUAGE = '''||value||'''') date_from FROM v$nls_parameters WHERE parameter = 'NLS_LANGUAGE'
以下两个代码工作正常：
TO_CHAR(tr.start_time,'Day,DD Mon YYYY', 'NLS_DATE_LANGUAGE = '''||'BRAZILIAN PORTUGUESE'||'''')
TO_CHAR(sysdate,'Day,DD Mon YYYY', 'NLS_DATE_LANGUAGE = '''||nls.value||'''')
完整代码如下：
WITH nls AS
(SELECT value FROM v$nls_parameters WHERE parameter = 'NLS_LANGUAGE'
)
