如何修改此PHP查詢以添加數據庫值'timestamp'？

Question

我使用下面的查詢另一個＃1用戶幫助我，這是完全新的給我：

"SELECT CONCAT(u1.firstname,' ',u1.lastname) as sender,CONCAT(u2.firstname,' 
',u2.lastname) as receiver, t.points as points FROM transactions t INNER JOIN users u1 ON 
u1.id=t.sender_id INNER JOIN users u2 ON u2.id=t.receiver_id ORDER BY date DESC limit 5" 

它的正常工作，但我意識到我沒有得到來自數據庫的整個價值'timestamp' 。如何將timestamp添加到查詢中，以便在結果中回顯它？

'timestamp'存儲在transactions表中。

謝謝。

Answer 1

你只是需要在查詢中添加t.timestamp。

"SELECT CONCAT(u1.firstname,' ',u1.lastname) as sender,CONCAT(u2.firstname,' 
',u2.lastname) as receiver, t.points as points, t.timestamp FROM transactions t INNER JOIN users u1 ON 
u1.id=t.sender_id INNER JOIN users u2 ON u2.id=t.receiver_id ORDER BY date DESC limit 5" 

Answer 2

使用

"SELECT CONCAT(u1.firstname,' ',u1.lastname) as sender,CONCAT(u2.firstname,' ',u2.lastname) as receiver, t.points as points, t.timestamp as timestamp FROM transactions t INNER JOIN users u1 ON u1.id=t.sender_id INNER JOIN users u2 ON u2.id=t.receiver_id ORDER BY date DESC limit 5"
