SELECT SUM(amount) as order 
FROM VendorTransaction 
WHERE order_id = 7496 
AND payment_mode = 'order'
ORDER BY id DESC

  

错误：SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中出错;查看与您的MySQL服务器版本对应的手册，以便使用接近＆＃39;顺序的正确语法   FROM VendorTransaction

Answer 1

订单是另一个保留字更改

SELECT SUM(amount) as my_order 
FROM VendorTransaction 
WHERE order_id = 7496 
AND payment_mode = 'order'
ORDER BY id DESC

或使用背景

SELECT SUM(amount) as `order`
FROM VendorTransaction 
WHERE order_id = 7496 
AND payment_mode = 'order'
ORDER BY id DESC

Answer 2

使用它： 选择SUM（金额）作为＆＃39; order＆＃39; FROM VendorTransaction WHERE order_id = 7496 AND payment_mode =＆＃39; order＆＃39; ORDER BY id DESC
