Retreive External data from SQL making connection to SQL server take a long time

Question

I have an Excel pivottable based on a view from SQL server. The view gets data from 2 databases on the sames server. I have the sames login for both databases and also the same rights (datareader, datawriter and owner). When running the view from within
the SQL Server management tool it goes quick. In Excel once the connection is made everything goes fast. Only making the connection takes a very long time. When I use a view with data from a single database then everything is fine and goes fast.
Example of the situation: I use the example view below in an excel pivot. This gives as result that the connection takes very long.
SQLServer A
View CustomerInfo which contains the following query.
Select * FROM databaseA.dbo.Customers as Customers
CROSS APPLY
SELECT *
FROM databaseB.dbo.Contacts as Contacts
Where Customers.Number = Contacts.CustomerNumber
) AS Contactdata
When I remove the CROSS APPLY part, the connection is made directly
We login to SQL with normal logon  (not windows security) The user has the same rights on both databases.
I hope the problem is clear. Does anyone have an idea of how I can solve this problem?

Answer 1

-1* ( prior dataid ) = parentid
is it multiplying -1 times the prior dataid ?that's exactly what it's doing
you need:
prior dataid = ABS(parentid);
not knowing you're data, and therefore assuming that dataid is always positive (since it doesn't have an ABS), and that parentid can be positive or negative, your criteria becomes
parentid = prior dataid (handles both are positive)
or parentid = negative of prior dataid (handles parentid is neg, dataid is pos)
since the "prior" must be right next to the column (dataid), I put parens around the whole thing, and then mult by -1
