1064 - 您的SQL语法出错;查看与您的MySQL服务器版本相对应的手册，以获得正确的语法，在第3行的'account_ LIMIT 0,30'的total_assets顺序附近使用

Answer 1

删除AS total_assets

SELECT account_name ,sum(total_balance) from transaction 
where account_name IN('cash','a/r','supplies','prepaid','land','gold')
ORDER BY account_name

Answer 2

你的别名错误。

SELECT account_name ,sum(total_balance) from transaction 
where account_name IN('cash','a/r','supplies','prepaid','land','gold')
AS total_assets
ORDER BY account_name

应该是

SELECT account_name ,sum(total_balance) AS total_assets
from transaction 
where account_name IN('cash','a/r','supplies','prepaid','land','gold')
ORDER BY account_name

Answer 3

将as total_assets移到select子句中。这用于定义列别名：

select account_name, sum(total_balance) as total_assets
from transaction 
where account_name in ('cash', 'a/r', 'supplies', 'prepaid', 'land', 'gold')
order by account_name;
