SQL Join excel vba

Question

我想在访问VBA中运行以下SQL查询，并且出现连接错误。

我似乎无法弄清楚问题所在。我确定有一些显而易见的东西我只是俯视。

SELECT a.LateDate, a.LateAgent, a.LateTime, b.PBXID, 
     (b.FirstName + ' ' + b.Surname) as FullName 
from tblLateLog a 
    INNER Join tblAgents b on a.LateAgent = FullName 

Answer 1

的ON子句中不能使用列别名：

SELECT a.LateDate, a.LateAgent, a.LateTime, b.PBXID, 
     (b.FirstName + ' ' + b.Surname) as FullName 
from tblLateLog a 
    INNER Join tblAgents b ON a.LateAgent = (b.FirstName + ' ' + b.Surname) 

Answer 2

您不能在查询的相同上下文中使用别名来进行连接。这样做，因为这：

SELECT a.LateDate, a.LateAgent, a.LateTime, b.PBXID, 
     (b.FirstName + ' ' + b.Surname) as FullName 
    FROM tblLateLog a 
    INNER Join tblAgents b on a.LateAgent = (b.FirstName + ' ' + b.Surname)
