Query From Interbase Using Linked Servers

May 8, 2007

created a linked server. But i can't query the table.
i tried different combinations but they dont work.

LS: dccs_danville
DB: intdccs_dv.gdb
table:tblload

select top 10 * from dccs_danville.INTDCCS_DV.gdb.tblload
select top 10 * from dccs_danville.INTDCCS_DV.dbo.tblload
select top 10 * from dccs_danville.INTDCCS_DV...tblload
select top 10 * from dccs_danville.INTDCCS_DV.tblload
select top 10 * from dccs_danville...tblload
select top 10 * from dccs_danville.INTDCCS_DV.tblload

also tried EXEC sp_tables_ex 'dccs_danville'
tblload is able to be queried.

anyone know what is wrong?

OPEN QUERY: - LINKED SERVERS

Jan 11, 2000

I have successfully connected to a sybase 11 database and have successfully run a couple of open query statements against this database, I have now placed this open query in a stored procedure and it works well, but when I want to pass parameter variables has part of my open query it does not like it. It asks me to declare the variable which is a parameter of the stored procedure. Is there any way I can pass in a variable value has part of my query

************************************************** *********************8
CREATE PROCEDURE qse_check_label_projectid
@projectid char(18)
AS

Select * from openquery(MRTEST32,'SELECT
Project_id
FROM
DBO.MRT_PROJECT
WHERE
Project_id = @PROJECTID ')
************************************************** ***************************
Please I believe there should be a way to pass a value through this open query function!

After SQL 2005 SP2, Query To Apartment Linked Servers Fails

Mar 6, 2007

We have a linked server that is an Apartment model OLE DB Provider. It works fine on SQL 2005 SP1. After applying SP2, we get the following msg when running a query against the linked server. I cannot find anything in the SP2 doc that indicates a change of behavior for linked servers. Any ideas ?

Bill

Msg 7308, Level 16, State 1, Line 1

OLE DB provider 'DBAmp.DBAmp' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.

View Performance, Linked Servers, Query Specifiying Uniqueidentifier

Jul 20, 2005

Greetings,I have 3 servers all running SQL Server 2000 - 8.00.818. Lets callthem parent, child1, and child 2.On parent, I create a view called item as follows:CREATE view Item asselect * from child1.dbchild1.dbo.Item union allselect * from child2.DBChild2.dbo.ItemOn child1 and child2, I have a table "item" with a column named "id"datatype uniqueidentifier (and many other columns). There is anon-clustered index created over column "id".When I connect to the parent server and select from the viewSelect id, col1, col2, �. From item where id =�280A33E0-5B61-4194-B242-0E184C46BB59'The query is distributed to the children "correctly" (meaning itexecutes entirely (including the where clause) on the children serverand one row is returned to the parent).However, when I select based on a list of idsSelect id, col1, col2, �. From item where id in(�280A33E0-5B61-4194-B242-0E184C46BB59',�376FA839-B48A-4599-BC67-25C6820FE105')the plan shows that the entire contents of both children item tables(millions of rows each) are pulled from the children to the parent,and THEN the where criteria is applied.Oddly enough, if I put the list of id's I want into a temp tableselect * from #bv1id------------------------------------280A33E0-5B61-4194-B242-0E184C46BB59376FA839-B48A-4599-BC67-25C6820FE105and thenSelect id, col1, col2, �. From item where id in (select * from #bv1)the query executes with the where criteria applied on the childrendatabases saving millions of rows being copied back to the parentserver.So, I have a hack that works (using the temp table) for this case, butI really don't understand the root cause. After reading online books,in a way I am confused why ANY of the processing is done on thechildren servers. I quote:================================================Remote Query ExecutionSQL Server attempts to delegate as much of the evaluation of adistributed query to the SQL Command Provider as possible. An SQLquery that accesses only the remote tables stored in the provider'sdata source is extracted from the original distributed query andexecuted against the provider. This reduces the number of rowsreturned from the provider and allows the provider to use its indexesin evaluating the query.Considerations that affect how much of the original distributed querygets delegated to the SQL Command Provider include:�The dialect level supported by the SQL Command ProviderSQL Server delegates operations only if they are supported by thespecific dialect level. The dialect levels from highest to lowest are:SQL Server, SQL-92 Entry level, ODBC core, and Jet. The higher thedialect level, the more operations SQL Server can delegate to theprovider.Note The SQL Server dialect level is used when the providercorresponds to a SQL Server linked server.Each dialect level is a superset of the lower levels. Therefore, if anoperation is delegated to a particular level, then Queries involvingthe following are never delegated to a provider and are always it isalso delegated to all higher levels.evaluated locally:�bit�uniqueidentifier================================================This suggests to me that any query having where criteria applied to adatatype uniqueidentifier will have the where criteria applied AFTERdata is returned from the linked server.Any ideas on the root problem, and a better solution to get the queryand all the where criteria applied on the remoted linked server?Thanks,Bernie

Possible To Query Linked Servers WITH OUT Distributed Transaction Coordinator Enabled?

Jan 24, 2008

Is it possible to query linked servers without the Distributed Transaction Coordinator service enabled or allowing network access?

Is that ONLY for transactions? What if I just wanted to read the data and nothing else?
