SQL Join excel vba

Question

我想在訪問VBA中運行以下SQL查詢，並且出現連接錯誤。

我似乎無法弄清楚問題所在。我確定有一些顯而易見的東西我只是俯視。

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子句中不能使用列別名：

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

您不能在查詢的相同上下文中使用別名來進行連接。這樣做，因爲這：

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)
