<code>SELECT ea.id, ea.name, ea.capital_balance, ea.total_balance, ea.available_balance, ea.cashable_balance, ea.market_value as old_market_value, mv.market_value, ea.total_balance + mv.market_value as total_value, ea.brokerage_rate, ea.state, ea.description, ea.created_at FROM external_accounts ea, ( SELECT c.external_account_id, SUM(c.amount) AS market_value FROM ( SELECT a.external_account_id, a.total_count * b.price AS amount FROM main_inventories a JOIN stocks b ON a.stock_code = b.code ) AS c GROUP BY c.external_account_id ) AS mv WHERE ea.id = mv.external_account_id </code>
Mainly because I don’t know how to write the sub-Select section. The reason why I have to write it in one sql is because it involves sorting.

Associate the table relationships. In the query, the algorithm operations in the query can be completed by PHP. You can take a look at this
<code>Laravel的关联,可以使用分组,返回字段和聚合函数 </code>
