多币种 REGEXP_SUBSTR Oracle11g
第一次在这里发布问题，所以我希望我不要把它弄得太糟糕。
我创建了一个查询，可以提取各种客户订单详细信息，包括收费价格、产品标价和大单，即通过提醒电子邮件发送给客户的价格。
使用 REGEXP_SUBSTR，我可以匹配电子邮件 HTML 内容中各种货币的所有价格，但我遇到了某些缺少逗号或句点的价格货币缩写组合的输出问题：即 123 kr、999 Pesos 或 1 050 Kč。
如何使上述情况与其他价格格式的输出相匹配？
我从 Gary 的回答中汲取了很多“灵感”：Regex currency validation。

- 1.4">€25,99
- 1.4">£15.99
- 1.4"> 123 克朗
- 1.4"> 1234 英尺

输出

- 20.00
- 20.00
- 25.99
- 15.99
- 123 克朗
- 1234 英尺
- 999 比索
最后三个示例不应有空格和/或数字后面的任何字母。
如何从输出中删除它们但保留数字？
我意识到这可能是由于我拥有多个捕获组，所以我看到了三个潜在的解决方案：
- 改进正则表达式以消除组的过度使用（我不够熟练，无法弄清楚这一点）......
- 以某种方式编写导致所需输出的正则表达式非捕获组。我很遗憾地了解到 (?:) 根本行不通。
- 利用 SQL 函数参数从 REGEXP_SUBSTR 中选择子表达式。但是，这似乎不允许输出中有多个子表达式。
SQL
SELECT
REPLACE(REPLACE(REGEXP_SUBSTR(nnc.MESSAGE, '(NT\$|SAR)\s(\d{2,5})|\d{1,4}([.,]\d{3})*([\s.,]\d{2,3}|[^\W]\d+(\d{1,4})*\s(kr|zł|Pesos|Kč|Ft|บาท|SAR|₪))'),',','.'),' ','') AS EMAIL_PRICE_SENT
FROM tablename
WHERE clause;
这是带有几个嵌套 REPLACE 函数的完整语句，用于将输出格式化为系统格式。
- 请参阅此处的正则表达式：Regex 101 Link。
我知道这是错误的语言，因此它不会提供 100% 准确的测试，但我发现它在针对数据库运行之前非常有帮助。我总是乐于接受更好的工具建议！
我在这方面花费的时间比我引以为豪的要多，因此我们将不胜感激任何帮助。
谢谢，尼克
