Mysql 如何在sql中修复此语法错误？

1064-您的SQL语法有错误；检查与您的MySQL服务器版本对应的手册，以了解第3行的“按帐户排序的总资产数量\u名称限制0,30”附近使用的正确语法

作为总资产删除

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

你的别名放错地方了

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

应该是

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

---

将

作为总资产

移动到

选择

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

我想你需要给

sum（总余额）命名为总资产

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;
