Linked Server Problem When Querying
May 29, 2006
I have a linked SQL Server on another machine which is created using a stored procedure that executes the following:
EXEC sp_addlinkedserver @server = 'AchillesMixed', @srvproduct = ' ', @provider = 'SQLNCLI', @datasrc = 'ArchillesMixed', @catalog = 'DB_INTRANET'
The stored procedure executes successfully and I can also succesfully DROP the linked server. However when I try to query tables in linked databases using:
SELECT * FROM DB_INTRANET...Employees
I get the following error:
OLE DB provider "SQLNCLI" for linked server "DB_Intranet" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0 TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18452, Level 14, State 1, Line 0 Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
The logins are Windows Authentication and even if I use sp_addlinkedsrvlogin to map logins it still gives me the same error.
I have no problems linking and querying linked Access Databases but can't do it for the SQL Server DBs.
Does anyone have any suggestions please.

How do I specify the Catalogue while querying a linked server?
For exmaple, I have a remote SQL 2000 server as a linked server on my server. I will refer to it as "ServerRemote." I was given access to that server through my Active Directory Domain account and the catalogue 'master' was set as my default database.
Aside from having the admin change my default database, is there a way to query a linked server and specify the catalogue in the query?
Right now I use the following code to query the default catalogue for the linked server:
SELECT * FROM ServerRemote...ViewName
I've tried various queryies for a different catalogue but always get a table not found error:
SELECT * FROM ServerRemote..DatabaseName.ViewName
or
SELECT * FROM ServerRemote.DatabaseName..ViewName
or
SELECT * FROM ServerRemote.DatabaseName.ViewName
all return errors

I would like to query a linked server and join that database to my local database. I finally was able to get it to work and I got this query to work:
select * from openquery([hcda-storagesrvlaserfiche], 'select * from toc where parentid=358')
I would like to join one of my tables from my local database to the query. How can I do this? Thanks!

Creating a web application. Running a simple query "SELECT username FROM vwCustomer"
vwCustomer is a view built on top of an Access DB which is set up as a linked server. Within SQL Server that view responds immediately. But when I try to access it from an ASP page it takes over 20 seconds to respond.
Used the following to create the linked server:
EXEC sp_addlinkedserver 'DBName', 'Jet 4.0', 'Microsoft.Jet.OLEDB.4.0', 'c:databasesdatabase.mdb'
GO
EXEC sp_addlinkedsrvlogin 'DBName', FALSE, NULL, 'Admin', ''
GO
The view is simply(this works fine in SQL Server):
SELECT * FROM DBName.db.dbo.customer
The ASP page:
SELECT * FROM vwCustomer
Can anyone give me a hint as to where the bottleneck is? Or how I can figure that out using SQL Profiler or something?
Please help!

Guys ...
I have a SQL SERVER 2005 running on my local machine. My local machine is also configure for web applications through IIS.
There is a remote oracle db, which is maintained by another department. They gave us read only access but they discourage web access over their oracle database.
Even if you try to access it through web ... they come to know that certain logins are trying to access it through web ... How ... i dont know.
Now what i did is linked that oracle database with my SQL server 2005 and developed an ASP.NET application which is indirectly accessing oracle database though my SQL Server 2005.
Whenever a user visits my web application on the backend the authentication done on my sql server but the query runs on linked oracle server... as I open connection to my sql server 2005
do you guys think that Oracle database administrator can ever know that his oracle db is access through a web application. whereas they allow us to copy required data on our machines through SQL Server 2005?

I am using Linked Server in SQL Server 2008R2 connecting to a couple of Linked Servers.
I was able to connect Linked Servers, but I cannot point to a specific database in a Linked Server, also, I cannot rename Linked Server's name.
How to point the linked server to a specific database? How to rename the Linked Server?
The following is the code that I am using right now:
USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
@server = N'Machine123Instance456',
@srvproduct=N'SQL Server' ;
GO
EXEC sp_addlinkedsrvlogin 'Machine123Instance456', 'false', NULL, 'username', 'password'

Is there a way to bypass the syntax checking when adding a stored procedure via a script?
I have a script that has a LINKed server reference (see below) .
INSERT

ACTDMSLINKED does not exist at the time I need to add the stored procedure that references it.
PLEASE to not tell me to add the LINK and then run the script. This is not an option in this scenerio.

I've been digging for a while to try to find something, even had a consultant looking for me, but came up empty haned.
What I want to do is this:
I activated the Security Audit level for all logins. I want to be able to report last login date for every user from the log, and all login events for SA or any other defined super users.
Is it possible to Query the SQL Server Logs to report this information?
This is for proposed Sarbox Database Security settings.

I know that a heterogeneous query joining tables from two different servershas performance penalties but is the same true when joining tables from twodifferent databases on the same SQL Server 2000 instance?We are looking at setting up a Data Warehouse using DTS on a SQL Server boxand I'm wondering about the best way to logically set it up; i.e. one bighonking db or several dbs determined by some logical organization. With thelatter there will still be some queries that would need data from more thanone db and I'm wondering if that will have worse performance than if theywere all in one db.I thought that was the case in older versions of SS, but I couldn't findanything in 2000's BOL that indicated a problem with that.TIA

I am remotely logging onto a MS SQL 6.0 server using sp_addlinkedsrvlogin.
When I try to query against the table on this server I get the following error
message:
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' reported an error.
[OLE/DB provider returned message: The data source can not be used, because it DBMS version is less than 6.5.0.]
I know that 6.0 doesn't support OLEDB but shouldn't 7.0 be able to access this
using odbc. Do I need to do anything other than set up the dsn on odbc.
Any feedback on this would be great.
Cheers,

I have an xml document that (for this example) I've simplified to look like this:
<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'
xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882'
xmlns:rs='urn:schemas-microsoft-com:rowset'
xmlns:z='#RowsetSchema'>
<s:Schema id='RowsetSchema'>
[code]....
When I try querying the xml document in SQL, I get nothing back, unless I remove the schema information. I'm using this:
declare @x xml
select @x = P
from openrowset (bulk 'E:VehicleOption0514.xml', single_blob) as Products(P)
declare @hdoc int
exec sp_xml_preparedocument @hdoc output, @x

<BS>
<B Id="5" />
<B Id="3" />
<B Id="4" />
<B Id="6" />
<B Id="15" />
<B Id="7" />

When I insert this into a temp table, the order get mixed up.
SELECT I.value('@Id', 'INT') ProductId
INTO #ProductList
FROM @Products.nodes('/BS/B') AS T(I)
When I select out of #ProductList the order is random and different from the XML.

I am currently migrating our Intranet from SQL Server 7 to SQL Server2000 and have hit a problem with one of the applications. Theapplication in question executes the folloiwing query against thedatabase:select * from employee where emp_id = 760In SQL Server 7 this works without a problem, however, in SQL server2k the following error is returned:[Microsoft][ODBC SQL Server Driver][SQL Server]Syntax error convertingthe varchar value 'Con25' to a column of data type int.This is clearly because the column emp_id is a varchar, I understandthat this code has not exactly followed best practices but do not wantto have to trawl through the application and surround all instanceswith apostrophes.Is it possible to make SQL 2k act in the same way as SQL 7 or will Ihave to trawl through the code and correct the SQL statements.Thanks for any help.John

HI,
I'm trying to implement a site search. The only problem is that some of the pages have more than 8000 characters (like the press release pages) so I had to use the TEXT datatype (sql server 2000). I wrote a simple stored procedure to query the column, however it does not return any results. I'm assuming this is due to the fact that it is the TEXT datatype. ANY help would be GREATLY appreciated. Code below:
CREATE PROCEDURE sp_SiteSearch
@keyword text
AS
SELECT PageText
FROM tbl_Pages
WHERE PageText LIKE '%@keyword%'
GO

I have a table (we will cal DateTable) with several (20) columns, each being a date type. Another table's (Project) PK is referenced in the DateTable.
I am trying to write a query that will pull all dates for a specific project from the DateTable if they meet certain criteria(i.e. if the date is <= 7 days from now.
I started with a normal select statement selecting each column with a join to the project and then a where clause using
(DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()) OR (DateTable.ColumnName BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE())) ...
The rest of the columns(all with OR between them).
The problem with this is that because I am using OR once one of the dates meets the criteria it selects all the dates that are associated with the project. I ONLY want the dates that meet the criteria and don't care about the rest.
Obviously because I have all the columns in the select statement... So I need something like
Select ALL Columns
from DateTable d
Join Project p
where p.ProjectID = d.ProjectID AND only dates BETWEEN GETDATE() AND DATEADD(day, 7, GETDATE()))

I'm working on a query in which I need to get few nodes values from the XML data by using the value from SQL column (MessageContentType) in this query. I'm able to get the nodes value when i hard code the value in the query but the problem is MessageContentType will vary from some records in the table, due to that I'm not getting the corresponding node values. I have tried few ways to get this value dynamically but I'm missing something.
Sample Table Data
MessageContentType | BodySegment
xx:ADT_A03_26_GLO_DEF | <ns0:ADT_A03_26_GLO_DEF xmlns:ns0="http://microsoft.com/HealthCare/HL7/2X">.....
Current Query - HardCode Script
SELECT
ID,MsgContentType
BODYSEGMENT,
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /xx:ADT_A03_26_GLO_DEF[1]/colxx[1]/colxx[1]','varchar(300)') AS TimeSpan
FROM
s
When i tried the below line of script, I'm getting this error "[color=#FF0000]The argument 1 of the XMLdata type method "value" must be a string literal.[/color]"
Concat MsgContentType Column
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /'+MsgContentType+'[1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
To overcome that error i used sql column but I'm getting this error [color=#FF0000]XQuery [S.bodysegment.value()]: Syntax error near '[', expected a "node test"[/color].
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /[sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
I tried this line of script, i didn't get any error by timespan is coming as null, I do hope this script not pointing the correct node to traverse the sibling node.
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /*[local-name()=sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan

I created an Image for the Database in sqlserver 2000. When I am querying directly the database as "Select * from employee", it is returning the result set.
But, when I am querying Database image with same query. It is giving error
Server: Msg 208, Level 16, State 1, Line 1
Invalid object name 'Employee'
It is expecting the Database Owner. If I do query like "Select * from [Owner].employee", it is working fine.
My requirement is not use owner in queries, it should be simple query ("Select * from employee").
Can any one, help me out.
Thanks in advance.

I'm fairly new to SQL and am just setting up a Windows 8 app using an Azure SQL server. The issue I have is looking up a part number supersession and getting the latest number. One part number can have multiple supersessions (ie RTC5756 > STC8572 > STC3765 > STC9150 > STC9191 > SFP500160 ).The data I am supplied monthly has both the superseeded items and the supersession information in both columns and is not easy to decipher - for example:
Supersessions Table
----------------------
RTC5756 | STC9191
SFP500160 | STC9191
STC9191 | STC2951
STC3765 | STC9191
STC8572 | STC9191
STC9150 | STC9191
[code]...
The newest part number is kept in a separate table - called "source" - which in this instance is SFP500160. I need access to the latest part number but also to the part's previous numbers, due to the fact that some people may still be stocking them as an old part number and for them to search by. Is there an easy and efficient way of doing both a lookup for the supersessions and a join on the two tables to minimize the queries on the database?

I am setting up extended events more or less just fine, however I am a bit confused as to how to read and load them into a table for querying. In particular the offset part - is there a way to load just a given dates worth in?
I've got the files configured to be 20MB before rolling over, the XE is running all the time.
So if i load in the full file now, say that covers 2.5 days worth, when I load it again tomorrow to get the updated data I'm also reloading today, which is a waste?
I presume I am going about this wrong, but lack an example that really goes into detail of practicalities of loading this data.
