Mysql group by 和表一中一列的總和

Question

目前我正在運行一個 sql 腳本，該腳本通過以下查詢從兩個表（cc_transactions 和 cc_transaction_status）給出結果：

SELECT cc_transactions.transAmount as amt
FROM cc_transactions 
INNER JOIN cc_transaction_status ON cc_transactions.id = cc_transaction_status.transaction_id 
WHERE account_id = '11E5F26C8164C3BABF85F8B156B0DBF5'
GROUP BY cc_transactions.id 
HAVING MAX(cc_transaction_status.sortOrder) = 0

結果是

amt     
200.0000
300.0000
1000.0000

我希望結果是

amt     
1500.0000

任何人都可以看看這個。

Answer 1

SELECT SUM(Amount.amt) from (
      SELECT cc_transactions.transAmount as amt
      FROM cc_transactions 
      INNER JOIN cc_transaction_status ON cc_transactions.id = cc_transaction_status.transaction_id 
      WHERE account_id = '11E5F26C8164C3BABF85F8B156B0DBF5'
      GROUP BY cc_transactions.id 
      HAVING MAX(cc_transaction_status.sortOrder) = 0
) as Amount;

如果您的查詢運行成功，那么它會給出 sum....
