MySQL：運行窗口查詢時出錯

Question

我正在嘗試執行 WINDOW 查詢，如下所示：

SELECT 
DATE(ts),
oi, 
avg(oi) OVER(PARTITION BY DATE(ts) )  
FROM bybit_oi_1d_BTCUSD

它給出了以下錯誤：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(PARTITION BY DATE(ts) )  
FROM bybit_oi_1d_BTCUSD LIMIT 0, 25' at line 4

Answer 1

在 MySQL 8+ 或 MariaDB 10.2 之前沒有 Window 功能
