Question

select Client.FirstName + ' ' + Client.LastName 'Client Name',Staff.FirstName + ' ' + Staff.LastName 'Staff Name' from Client
inner join Job on Job.ClientID = Client.ClientID
inner join Staff on Staff.StaffID = Job.StaffID
Order by Client.FirstName,Client.LastName,Staff.FirstName,Staff.Lastname desc

我必须使用SQL将Client和Staff FirstName / LastName组合到一个列表中。它们在不同的表中，我不确定如何做到。

Answer 1

在MySQL if ($decoded->date < strtotime('-2 weeks')) {中是附加的。改用CONCAT函数：

或使用跳过NULL的CONCAT_WS函数：

SELECT CONCAT(Client.FirstName, ' ', Client.LastName) AS `Client Name`
     , CONCAT(Staff.FirstName, ' ', Staff.LastName) AS `Staff Name`

将两个字段表合并为一个列列表
