用貨幣對SQL字符串列排序

我有一個SQL數據庫，它有一個字符串列。裏面的數據是數字，如..用貨幣對SQL字符串列排序

$12,000,394.09 
$56,874.94 
$110,339,384.11

這是字符串列，但我想它與最低的頂部進行排序。是否有可能做到這一點？現在我只試過簡單的..

SELECT * FROM sales ORDER BY saleamount DESC

任何幫助將是偉大的。由於

你用什麼Db引擎？ –

爲什麼不將列類型更改爲數字，並且不存儲貨幣或將其存儲在不同的列中 –

我正在使用Oracle SQL Developer。我正在使用Java來檢索內容。 – user2703946

你可以用regexp_replace做到這一點只保留數字字符和小數點，並to_number的結果轉換爲數字：

select * 
from sales 
order by to_number(regexp_replace(string_num_field, '[^0-9.]+', ''))

在sql小提琴看起來不錯，但它試圖運行它時會拋出大量錯誤文本。 – user2703946

「錯誤的大文本」是什麼意思？ –

我將錯誤添加到第一篇文章。 – user2703946

如果所有的字符串都相同墊 - 從一個貨幣符號，逗號分隔符（如適用）和兩位小數 - 那麼你可以使用以下命令：

order by length(saleamount) desc, 
     saleamount desc

如果你想最小的值，然後再：

order by length(saleamount) asc, 
     saleamount asc

這裏是沒有正則表達式的一個老式的解決方案：

select amt_usd 
     , to_number(translate(amt_usd, '1234567890.,$', '1234567890.')) amt 
from t23 
order by 2 
/

工作SQL Fiddle。

當然，如果用戶在列中輸入了£或其他內容，就會中斷。從這個角度來看，正則表達式更安全。
