Question

我有这个使用SQL Server运行的经典ASP应用程序。我使用以下查询：

sql = "SELECT TOP 30 r.RMANumber, r.CompanyName, r.ContactName, r.Country, r.Phone, r.IssuanceDate, r.DateReceived, r.CreatedBy " & _
      "FROM rma r " & _
      "WHERE r.IssuanceDate >= '" & startDate & "' AND r.IssuanceDate <= '" & DateAdd("d", 1, CDate(endDate)) & "' AND r.RMAClosed = 'No' " & _
      "ORDER BY IssuanceDate DESC"

我想在其中添加INNER JOIN，但INNER JOIN会在不同的数据库中查找。我可以这样做：

sql = "SELECT TOP 30 r.RMANumber, r.CompanyName, r.ContactName, r.Country, r.Phone, r.IssuanceDate, r.DateReceived, r.CreatedBy " & _
     "FROM [database1].[dbo].[rma] r " & _
     "INNER JOIN [database2].[dbo].[users] u " & _

Answer 1

如果您的其他数据库位于另一台服务器中。输入服务器的IP地址，如下所示：

sql = "SELECT TOP 30 r.RMANumber, r.CompanyName, r.ContactName, r.Country, r.Phone, r.IssuanceDate, r.DateReceived, r.CreatedBy " & _
      "FROM [database1].[dbo].[rma] r " & _
      "INNER JOIN [ip address of other server here].[database2].[dbo].[users] u " & _

注意：确保您已连接并且可以访问其他数据库所在的服务器。
