LinkedServer And Pass Through Kind Of Security
Sep 14, 2006
Hi,
I am not expert on SQL server, i need to be able to access different server from withing sproc,
1. Is Linked Server is the best aproach.
2. If yes then how i set it up that it take all authenticated users of this server to remote, i tried with impersonate but it gives error that NT authority dont hae access etc etc (when i try run a sql that accesses remote server)
3. The reason i need to access remote server is ... one of the that table in my db (logTable) is getting to big it is 10 times the size of rest of the db altogether so i though i move it out not just from same db actully put it on a seprate server. so that all the tasks about main db would become easy etc.
any idea help

Hi Everybody,
I have 2 servers one has SQL 7.0 running on NT4.0 and another has SQL 2000 running on W2K Server. I have established a linked server for SQL 2000 from SQL 7.0.
I don't have any problem of creating linked servers for sql 2000 from sql 7.0. I am also able to create linked server logins to access the sql2000 tables. Even I am able to see the tables on the Databases.
EXEC sp_addlinkedserver 'SQL2K', '','SQLOLEDB','GENOMESQL2000'
sp_addlinkedsrvlogin @rmtsrvname = 'sql2k' ,@useself = 'false' ,@locallogin = 'genomeACCT1',@rmtuser = 'test2k',@rmtpassword = 'test2k'
exec sp_tables_ex N'sql2k' (Upto this I don't have any problem)
When I tried to execute a particular table from the database, I am getting the following error.
Select * From sql2k.northwind.test2k.payroll
Error:
******
Server: Msg 7314, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' does not contain table '"master"."test2k"."ven"'.
Can anybody give suggestions to solve this problem.
tks in advance,
Vasu

I added a Linked Server, like this:
EXEC sp_addlinkedserver
@server = 'ServidorPrincipal',
@srvproduct = 'SQLEXPRESS',
@provider = 'SQLNCLI',
@datasrc = 'TIC-IISQLEXPRESS',
@catalog = 'BDPrincipal'
GO
But now I can't do a selection:
SELECT * FROM ServidorPrincipal.BDPrincipal.dbo.tblCADENA;
Because it sends this message:
Server: Msg 7356, Level 16, State 1, Line 1
OLE DB provider 'SQLNCLI' supplied inconsistent metadata for a column. Metadata information was changed at execution time.
OLE DB error trace [Non-interface error: Column 'ID_CADENA' (compile-time ordinal 1) of object '"BDPrincipal"."dbo"."tblCADENA"' was reported to have changed. The exact nature of the change is unknown].
The linked Server is called "ServidorPrincipal".
The database is: BDPrincipal.
And the table is dbo.tblCADENA.
"changed at execution time" ¿What does it mean?
What is happening here?

Hi all,
I'm trying to change the datasource of a SQL Server LinkedServer using SMO
I've got the relevant linkedserver as an object, changed the DataSource property, and selected it again to confirm the change.
However, the change is lost as soon as the object is destroyed.
Looking at BoL I think I need to be using alter() method of the linkedserver class but I just get an error
Alter failed for LinkedServer '<servername>'.
any ideas how I should be using this class to do what I want?
I can post my script (PowerShell) if it would help.
Thanks, Robin.

I'm copying almost all contents of one table from one server/db to another. In relation to speed, what is the difference of using SSIS vs a linked server and sp? I'm going to do the benchmarks, but I'm curious about behind the scenes kinda stuff, theoretically which one if any should be faster and why?

Hello All,
I created two database instances in the same MS SQL SERVER 2005 named hafeez and local. I created a linked server from hafeez database to local named HTOL
I created a dummy table in local database named samplocal.
Now i am able to list the records using the linked server, for this i used the following query.
SELECT * FROM OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL');
Now the problem is, i am not able to insert the rows into the samplocal table using linkedserver. I am using the following query to insert the rows and getting the following errro.
INSERT INTO OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL') VALUES('tertertetttwertw');
Msg 7356, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI" for linked server "HTOL" supplied inconsistent metadata for a column. The column "nameandval" (compile-time ordinal 1) of object "SELECT nameandval FROM SAMPLOCAL" was reported to have a "Incomplete schema-error logic." of 0 at compile time and 0 at run time.
Is the above query correct? or shall i miss anything?
Please guide me.
Thanks in Advance
Hafeez Shaik.

Hi,
We currently have an application that primarily sits on SQL server and needs to access some legacy data in a DB2 database. The solution we are using is to use a linked server between the two servers. The problem with this is that complex queries occasionally cause the driver to fetch a complete table and filter that table locally. I wondered whether service broker (which I have never used) could allow me to access the DB2 database using MQSeries and thus speed up the application as our ODBC calls have low priority on our mainframe.
Thanks and sorry if this sounds a stupid use of service broker.

When running a query with a table from another SQL7 Server that is linked, if only 1 table from each server is specified, the query runs fast and returns only the data rows needed from the linked server. When another table is added on to query (on the server running the query) the query processor tries to run a remote query and return over 400,000 rows over the network. Any suggestions?

After running the following OpenQuery...
UPDATE OPENQUERY(LINKEDSERVER, 'SELECT START_ORDER_NO FROM "OECTLFIL" WHERE "FILE_KEY" = 1')
SET START_ORDER_NO = 0
----The START_ORDER_NO field contains a 48
SET START_ORDER_NO = 1~9
----The START_ORDER_NO field contains 49~57 respectively.
SET START_ORDER_NO = 10
---The START_ORDER_NO field contains 12337
SET START_ORDER_NO = 11
---The START_ORDER_NO field contains 12593
SET START_ORDER_NO = 12
---The START_ORDER_NO field contains 12849
incrementing by 256 as I increase the value passed...
ASCII 48-57 are the characters 0-9. The string '10' consists of the two bytes with the values 49 (0x31) and 48 (0x30). It is being viewed in reverse byte order as the value 0x3031 which equals 12337 (48*256 + 49).
The LinkedServer is Pervasive SQL 2000i using 'OLE DB Provider for ODBC'
The START_ORDER_NO field is a Numeric(8,0)
I'm thinking some kind of Unicode, or translation or code page issue, but I haven't had any luck yet.
I'm not sure how difficult this is, I don't think I'm a neophyte but I'm feeling like one...

I'm not looking for details or code, just general direction I should go. Here is my goal:
I have a SQL stored procedure that returns data which I will need to add spaces to, then end up with a space delimited text file.
This txt file will then be needed to be saved and emailed.
Also, I would like to be able to schedule this in the Task Scheduler for once a month execution.
Is this all just one big crazy idea?
Thanks for any help.

In the company that I work there are two offices, one is outside the city and the other is in the city. They are connected trough a DS0 using frame relay. The thing is that the comunication is very slow (the SQL server is in the city) and we want to add a new server at the office outside the city and we want at the end of the day replicate the data between the two servers so every server has the actual data. We didn't use primary keys, instead of that we used identities (autoincremental value administered by the server). What kind of replication should I use and why? (I'm new with SQL Server). There are 3 kinds: Snapshot, Transactional and Merge.

Hi,
I have a problem in a Stored Procedure SQL query im writing, basically what I want is something that works like this
WHERE intField IN (@strCommaSepList_Of_Integers)
First I tried this:
SELECT idComp_Clie_Bran_User, strComp_Clie_Bran_User_FirstName, strComp_Clie_Bran_User_Surname
FROM dbo.tblComp_Clie_Bran_Users
WHERE (fk_idCompany = @fk_idCompany) AND (fk_idComp_Client = @fk_idComp_Client) AND (fk_idComp_UserGroup IN (@strListUserGroupsAllowed))
But if I passed a 25,26 value to the last paramenet is gave an error saying:
Syntax error converting the varchar value '25,36' to a cllumn of data type int.
How can I get this to work??
If for example I manually put the WHERE IN values it works, ike this I mean:
SELECT idComp_Clie_Bran_User, strComp_Clie_Bran_User_FirstName, strComp_Clie_Bran_User_Surname
FROM dbo.tblComp_Clie_Bran_Users
WHERE (fk_idCompany = @fk_idCompany) AND (fk_idComp_Client = @fk_idComp_Client) AND (fk_idComp_UserGroup IN (25, 36))
But thats no use as I have to pass the list of values dynamically...
Please help!!

Here's a basic overview of my Table
ID identity int
ParentID int
Name varchar
Now, the root level items will have a ParentID of NULL, and the child nodes will have it's parent's ID in it's ParentID column (a simple self-referencing relationship).
However, when I select it, I would like to Order by ID, but then have all it's children right after it. For example, if this is the unsorted view:
Code:
ID ParentID Name
----------------------
1 <NULL> Test
2 1 Test Child 1
3 <NULL> Test 2
4 1 Test Child 2
5 3 Test 2 Child 1
I would like the sorted to look like:
Code:
ID ParentID Name
----------------------
1 <NULL> Test
2 1 Test Child 1
4 1 Test Child 2
3 <NULL> Test 2
5 3 Test 2 Child 1
Is this possible with my current structure? If not, how could I change it?

Hey all!
This may sound like a weird one but i couldn't think of a better audience to ask!
If you are a SQL Server DBA (or were, or aspire to be, or play one on T.V., etc.) and the CIO of your 2.something billion $ a year company has offered you an 1 hour forum to sit down and ask him anything you want with the pretense of getting a straight answer, what would you ask?
I know this offers an excellent opportunity to cut up a bit...and do so if you must (keeping us entertained around here is important too!)...but i'm looking for work related, SQL related, direction, strategy, etc, etc type stuff.
Not: 'Whats it like to drive a $250k 'benz to work everyday?' OR 'Can i have .5% of your $2,000,000 bonus this year?'
While i genuinely have those questions in my mind...i'm not looking to waste his $5,000 an hour ass's time - and I only have 1 hour to chew his ear off.
What do ya'll think?

Hi all,
Just can't figure this out. I'll try not to give a long-winded explanation (I hope), let's say this is the table, for example:
[Table1]
RowNumber | Value
1 | 4
2 | 6
3 | 3
4 |10
5 | 6
6 | 5
7 | 8
8 | 8
9 | 2
10 | 6
I want to write a query that creates a column whose values are similar to (ROW_NUMBER -1), and resets each time a value is present.
Using the above example, 6 will be the test value. So, I want to know how many rows it takes till 6 is repeated.
Output would be:
RowNumber | Value | Spread
1 | 4 | 1
2 | 6 | 0
3 | 3 | 1
4 |10 | 2
5 | 6 | 0
6 | 5 | 1
7 | 8 | 2
8 | 8 | 3
9 | 2 | 4
10 | 6 | 0
I think PARTITION BY can be used somewhere, with the ORDER BY on the [RowNumber] - but I'm just not sure on which ranking function to use, and how to reset the Ranking on the number 6 (above example).
Any help would be appreciated. This has been a mind-teaser for me, and I give
Thanks,
Denvas

I am gonig into interview for a junior developer position. The role involves a lot of SQL based work. Training is on the job, and they know I am new to this, but they want to know what I can do with SQL server by wednesday, and obviosuly I stand a better chance if I can do a reasonable amount by then.I am assuming I can practise with offline databases, so I would like to do that. Also I was wondering if there were any simple example databases I can load up.
I have downloaded and installed the software, and would like to know how to connect and create a test database.
There will be a small test in the interview and the questions are:
1. SQL Management and Data Extraction
For this task you will need to be familiar with database tables, data types and constraints. There will be some administration work using SQL Management Studio along with some T-SQL queries. You will need to show use of the SELECT, INSERT, UPDATE and DELETE statements. If you do not have SQL Server, you can download the express edition for free at the following URL. http://msdn2.microsoft.com/en-us/express/bb410791.aspx
2. XSLT
For this task I will be asking you to produce some HTML output displaying the data from an XML file. The concept is similar to ASP.
3. Database Design
You will be given a scenario for a company that requires some database software for the smooth running of their organisation. You will need to plan and design a data structure to accommodate these requirements. You will be allowed to spend as much time on this part of the test as you wish. Key information here is going to be database normalization.
These questions dont make a whole lot of sense to be at the moment, so would appreciate a breakdown in simpler terms.
This job will be a fantastic opportunity for me to get into development, and would appreaciate any help that you guys have to offer, thanks in advance.

Was able to solve my connection issues with my local (test) machine. However, now I've got a much bigger issue on my intranet machine (W2K Server that acts as a domain controller).
When I use essentially the same set up for connecting as I did for the other machine (adjusted for machine name, etc), I get the following message:
Login failed for user '[username]'. The user is not associated with a trusted SQL Server connection.
I went into the SQL Server Express Config, and discovered under "SQL Server 2005 Services>SQL Server(SQLEXPRESS)>Properties" that this service is set up to login as the Local System built-in account. When I try to change this to Network Service, I get the following popup error message:
Cannot perform this operation on built-in accounts. [0x8007055b]
1) This happens regardless of wheter I stop the service and try to reset, apply and restart, or simply try to change it while it's running
2) I can find nothing on the error code above anywhere on the Web (Google came up EMPTY).
Anyone have any ideas about this one?

Hi,
I have a query which gives me the following results:
lLedgerCode sGLCode bDebit TotalSum sGLDesc
61 6843000701 0 600ALPS Holding
33 8345000701 0 1116ALPS Premium Due
56 1000000701 0 1116Regular Premium Income
63 6836000701 1 516ALPS Group Holding
61 6843000701 1 600ALPS Holding
30 6842000701 1 600ALPS Policy Clearing
33 8345000701 1 1116ALPS Premium Due
The Column bDebit has either value '0' or value '1' in it ('0' being debit - positive amount, and '1' - credit, negative amount).
I would like it to show the net amount for each account. Therefore in plain English I would like to take all GLCodes that are the same (eg 6843000701) and sum all amounts that have debit value of '0' and subtract all amounts that have debit value '1'. Therefore I would only see '6843000701' code once, and the amount would be '0' becase 600 - 600 = 0.
The current query is:
SELECT dbo.tbGLTransactions.lLedgerCode, dbo.tbGLTransactions.sGLCode, dbo.tbGLTransactions.bDebit, SUM(curAmount)As TotalSum, dbo.tbLedgerCode.sGLDesc
FROM dbo.tbGLTransactions
INNER JOIN dbo.tbLedgerCode
on dbo.tbGLTransactions.lLedgerCode = dbo.tbLedgerCode.lLedgerCode
WHERE dbo.tbGLTransactions.lGLExtractRun = '452'
Group By dbo.tbGLTransactions.lLedgerCode, dbo.tbGLTransactions.sGLCode, dbo.tbGLTransactions.bDebit, dbo.tbLedgerCode.sGLDesc
Order By dbo.tbGLTransactions.bDebit, dbo.tbLedgerCode.sGLDesc
Is someone able to help me as to how i need to modify this query to get the desired result?
Thanks!
