查询两个表

我需要数匹配在GID的查询两个表

Dim iSubscriptionCount 

SQLCommand = "SELECT COUNT(*) AS Counter FROM Directories.GID, ClientSubscriptons.DirectoryGID FROM Directories, ClientSubscriptons WHERE Directories.GID = ClientSubscriptons.DirectoryGID;" 
      rsTemp.Open SQLCommand, objConn, adOpenStatic, adLockReadOnly 
      iSubscriptionCount = rsTemp("Counter") 
      rsTemp.Close 
      if iSubscriptionCount <= 0 then 
          %><a href="AddDirectory.asp?PGID=<% = rsDirectory("GID") %>"><% = GetIcon("Add", "Add Sub Directory", 25, True) %></a><%

将记录数我需要计算的匹配在GID的

你的问题不是很清楚......如果你只是想算你必须执行JOIN这样

SELECT COUNT(*) AS Counter FROM 
Directories join ClientSubscriptons 
on Directories.GID = ClientSubscriptons.DirectoryGID

的特许经营部分是完全隐藏目录和客户端订阅之间的比赛.. 。你要同时匹配表上franchiseGID？如果您的查询应该是这样的

SELECT COUNT(*) AS Counter FROM 
Directories join ClientSubscriptons 
on Directories.GID = ClientSubscriptons.DirectoryGID 
and Directories.FranchiseGID = ClientSubscriptons.FranchiseGID

对于你需要更加清晰，请

的记录数你有2个从条款.. 。 SQL后应当读...

SELECT COUNT(*) AS Counter, Directories.GID, ClientSubscriptions.DirectoryGID 
    FROM Directories, ClientSubscriptions 
    WHERE Directories.GID = ClientSubscriptions.DirectoryGID

您可能还需要一个

GROUP BY Directories.GID, ClientSubscriptions.DirectoryGID;

的Clie更准确的答案ntSubscriptons拼写错误。这可能是问题。 – IAmTimCorey 2011-05-05 15:34:10

我不太了解Visual Basic吗？但是你在同一个句子中有两个'FROM'。不会

SELECT COUNT(*) AS Counter 
FROM Directories, ClientSubscriptons 
WHERE Directories.GID = ClientSubscriptons.DirectoryGID

解决问题？
