mysql - 与表对象的内连接

Question

我想创建以下查询的内部联接

select listmybill.tid from listmybill  
inner join
Trainerdetails
on 
listmybill.tid=Trainerdetails.tid

这工作得很好，但我想在这个内部联接中创建这些表的对象，例如

select l.tid from listmybill  as l.listmybill
inner join
Trainerdetails as t.Trainerdetails
on 
l.tid=T.tid

但我收到语法错误的错误

Msg 102, Level 15, State 1, Line 1 Incorrect syntax near '.'.

如何创建这样的过程？

Answer 1

试试这个:

select l.tid 
from listmybill  as l
inner join Trainerdetails as t on l.tid=T.tid
