我有问题：

#1066 - 不唯一的表/别名：'clients'

SELECT request.*, 
       clients.ClientName AS ToClient, 
       clients.ClientName AS FromClient, 
       drivers.DriName, requesttype.ReqTName 
FROM request
    INNER JOIN clients ON clients.ClientID = request.ReqToClient
    INNER JOIN clients ON clients.ClientID = request.ReqFromClient
    INNER JOIN drivers ON drivers.DriID = request.DriID
    INNER JOIN requesttype ON requesttype.ReqTID = request.ReqTID
