哪個是將sql查詢的結果直接轉換爲圖表的X軸和Y軸的最佳方法

Question

我希望找到將sql查詢結果直接轉換爲X軸和Y軸的適當方法一個圖表，當你在聲明中有多個列。例如
SELECT city,country,count(*) FROM beer group by country having count(*) > 100 order by 2 desc我應該如何處理這個問題。

謝謝。

Answer 1

在你的情況，我想你只想把你的城市和國家列，將它們組合起來，就像這樣：

SELECT CONCAT(city , ', ', country) AS x_axis, COUNT(*) as y_axis 
FROM beer 
GROUP BY city, country 
HAVING COUNT(*) > 100 
ORDER BY country, city;
