查找大多數行的範圍MYSQL

Question

我有一個表格可以保存價格。這背後的想法是讓用戶建議他們認爲合理的價格。因此，例如，可以說我有一個表名tbl_Prices：

| id |price | 
|1 |1200 | 
|2 |50000 | 
|3 |50000 | 
|4 |45000 | 
|5 |506980| 
|6 |2000 | 

從表中我們可以看到，與大多數行範圍50000 to 506980。 所以我希望拿出一個查詢來找到這個範圍。我看了一下this answer。這是相當不錯的，但由於某些原因，我不能增加偏移，我可以勉強明白髮生了什麼，它產生：

|from_price|to_price|count| 
|499999 | 500003 |2 | 
|499998 | 500002 |2 | 
|499997 | 500001 |2 | 
|499996 | 500000 |2 | 
|500000 | 500004 |2 | 
|499996 | 450000 |1 |

我必須弄明白的解決方案，找出全部按範圍定義見下文：

SELECT 
CASE WHEN accountid BETWEEN 0 AND 216 THEN '0 to 216' 
WHEN accountid BETWEEN 217 and 319 THEN '217 to 319' 
WHEN accountid BETWEEN 320 and 429 THEN '320 to 429' 
WHEN accountid BETWEEN 430 and 539 THEN '430 to 539' 
WHEN accountid BETWEEN 540 and 649 THEN '540 to 649' 
WHEN accountid BETWEEN 650 and 759 THEN '650 to 759' 
WHEN accountid >= 860 THEN '860 +' END AS accountgroup, count(accountid) AS total 
FROM account 
GROUP BY accountgroup; 

輸出爲如下：

希望這將有助於。謝謝。
