2 个解决方案

#1

Not valid sql - Gas Consumption` is not contained in an aggregate function or the GROUP BY clause.

无效的sql - Gas Consumption`不包含在聚合函数或GROUP BY子句中。

Correct SQL query,

正确的SQL查询,

#2

Get rid of your order by clauses in your subqueries.

通过子查询中的子句删除您的订单。

Also, post what the syntax error says.

另外,发布语法错误说明的内容。
