Answer 1

关于所涉及的数据表没有任何信息并不容易！但是，如果名称有意义，您如何将月份转换为日期时间？如果它存在，试试这个：

SELECT communication.*, employeedetails.resourcename 
FROM communication, employeedetails 
WHERE employeedetails.employeenumber = communication.employeenumber and communication.project = employeedetails.projectname 
ORDER BY communication.day, communication.month, communication.year --due to style 5

即使我建议去寻找风格12

Answer 2

communication.month的数据类型可能是字符类型。如果这持有＆＃34; 1月＆＃34;对于1月等，那么SQL无法将该字符转换为日期时间。您需要附加一个字符串，以便SQL可以将其解析为日期时间例如ORDER BY CONVERT(datetime,communication.month + '01 2000',5)。

但是，首先将通讯日期存储为日期时间会更好......
