what is the best way to push records using linked server. below is my query on Source server
insert into LSDestserver.DB.dbo.tablename
select * from #temp order by abc desc
I initially thought to pull records from Source server to LSDestserver but its a temp table. I don't know whether it is possible or not. Is there any other way we can achieve this in optimal way.
I wonder if it possible to move data from tables on a linked server to a "normal database"?
Name linked server: Covas
Name table on linked server: tblCountries
Name field: cntCountryName
Name "normal" database: CovasCopy
Name "normal" table: Countries (or dbo.Countries)
Name "normal" field: Country
This is just a test setup. I figure that if I get this working the rest will be easier.
My current query:
select * from openquery(COVAS,'
INSERT INTO CovasCopy.dbo.Countries(Country)
SELECT cntCountryName FROM db_covas.tblCountries;')
I have an Oracle 9i server. To access the data in Oracle, I setup an ODBC connection to it and am able to return data from it using WinSQL (a general ODBC database client). The SQL statement is simply "SELECT * FROM COLOR" and all 133 records returned properly.
I need to copy the data from the Oracle server to SQL Express, therefore I set up linked server (by Microsoft ODBC provider) using the same ODBC connection as described above.
The problem is: only 32 records returned.
May I ask if there is any problem to this linked server setup?
Thanks.
I am currently trying to optimize an ETL process that pulls around 150 tables from a OLAP-esque system through a linked server. It's the AllScripts Touchworks EMR database, if that makes a difference. I am having a difficult time fitting an incremental load into a reasonable window of time. For instance, one table, which has around 40 columns, and a total of about 50 million rows, takes around an hour just to pull one day's worth of records when filtering on a single datetime field. The query is:
SELECT *
FROM OPENQUERY([linkedserver],
'
SELECT *
FROM Works.dbo.Visit
WHERE StartDttm BETWEEN ''2014-12-23'' AND ''2014-12-24''
'
)
Which, in the end, returns only about 30k records. However, in trying different approaches, I decided to test out bcp using the following code:
bcp Works.dbo.Visit out f:etlvisit.dat -n -S linkedserver.this extracted the entire table to flat file, but it only took about 15 minutes....add on another 3-4 to load that into the database on my end. Now, my ability to see what's happening on the remote server's end is very limited, but I know that the server has much higher specs than mine. They have 96GB memory vs. my 32GB, twice the cores I've got, etc. So how is this running faster by pulling the entire table over?
I figured that even in the worst case scenario of a full table scan, picking 30k rows out of the table that match a single criteria would certainly run faster than bringing the whole thing over. This isn't isolated to a single table, either. I finished running a test of the incremental extract/load vs. full extract/load via bcp (200GB of data). The incremental takes about 7 hours, bcp takes about 2 hours.
Hi,I used sp_addlinkedserver to link to a remote server through ODBC.When I execute select count(*) from LinkSrv.SI.DBO.SIHeader in SQL QueryAnalyzer. It returns 13705 records. But when I execute select * fromLinkSrv.SI.DBO.SIHeader. It only return 885 records. If I specify somecolumns, select ODCOMP, ODPONO, ODVDCD from LinkSrv.SI.DBO.SIHeader.It returns more records, 1213 records.I guess there is something limit the return storage, but I can notfind it.Any suggestion will be appreciated. Thank you

I have a system where people can apply for registration and also a registration fee is involved. The screen where the application is captured has a couple of inserts into different tables. Each of these tables have triggers on them to transfer data to a linked server and they work fine. Today I just added another trigger on a different table but also part of this same save process. Now I am getting the following error:
Microsoft OLE DB Provider for SQL Server error '80004005'

I do not know this error and think it might be time-out.
I have created a linked server that point to a firebird database, everything is fine, I can query the database with something like
Select * from MYLINKEDSERVER...MYTABLE
Now , can i use tablediff utility with this linked server. If yes, any example ..
I would say also that performance is not very important to me. this would be used at the end of the day to make some sort of replication by generating a sql script with datadiff, and run it on a local sql server database and a web based SQL database. The replication is not an option since i am using a shared web hosting and replication is disabled on it .
I have a SQL Server 2012 instance set up with a linked server to an Oracle Database. I need to build a stored procedure (single NVARCHAR(6) parameter in: @accountID) which executes a select statement against the Oracle DB.
Everything's working fine when testing with 'EXEC (''<oraclecodeblock>'') at LINKEDSERVERNAME' if I hard code the value of @accountID in <oraclecodeblock> but when I encapsulate it all within sp_executesql and attempt to parameterize @accountID it's throwing ORA-01722 'invalid number' errors on the Oracle DB. The parameterized value is NVARCHAR as are the account numbers.
Working:
DECLARE @accountID VARCHAR(6);
SET @accountID = '10842';
DECLARE @sql NVARCHAR(MAX);
SET @sql = N'EXEC (''SELECT * from A.Accounts WHERE ID = ''''10842'''';'') AT LINKEDSERVER';

i didn't figure out how to add a firebird linked server via ODBC
my system :
win 7 pro 64
SQL server 2012 express 64
firebird 2.5.3 64
Official ODBC drivers 64
i have created the odbc source without problem, and checked that in visual studio and ssms import data wizard , both show me the data from firebird database but when i try to create a linked server , i have something like this message (the image is from the web)
Used linked-server during logon trigger? is it possible? i know we can access tables, SPs, etc with in that server, if i want to check something in other server during logon trigger, can i do it?
View 0 Replies View RelatedHow do you name sql linked-servers in your company ?
we have many legacy systems (random naming), but mostly newer systems follow this pattern
<ENVIRONMENT><APPLICATION><FUNCTION><VIRTUAL><NUMBER>
e.g.
PRD-FAX-DB-V01, TST-PAY-WEB-P02 etc.
We have link-servers all over the place. The ideal naming convention should satisfy following:
- developers should not have to modify code when deploying between environments DEV->TEST->PROD. This rules out using actual server name as linked-name.
- the name should easily identify actual server without much mental translation. This rules out relevant but generic names like FAXSERVER or PAYSERVER
- also, if the name could state that it is a linked-server e.g starting with LINK_, it works when reading the code.
So, I was thinking the link-name should simply remove the environment :
e.g LINK_FAX_DB_V01
that way, on DEV box, the underlying sql data source could point to the dev server, while on test, it could point to test server etc. without having to change code, and also knowing which server it's pointing to by just adding a TST or PRD in front-of it.
I've got an OLEDB DB2 linked server to a db2/AS400 instance and selecting from a table on the server has never caused problems before. One of the columns is a large text field. If I select all the columns but the large text field, it returns as normal, but including the large text field now, I get:
"Transport error: shared memory provider error: 0 - no process is on the other end of the pipe"
The largest entry in the text field is about 5k characters, and there don't appear to be any strange characters.
As a database developer, I have so many databases that I "own" scattered across various servers that it''s getting difficult to remember where all of my databases reside. It doesn't work that the DBAs have taken to some very hard to remember server naming conventions.
I was going to create aliases via the configuration manager, but it turns out the DBAs overwrite my entries each night with THEIR aliases and they won't add any for my use.
So I decided to simply add some records to my host file so that instead of having to connect to "SERVER-AD_DADF-DAFDASS" I can just use "CustomerA".
This solution seems to work until I tried to access a linked server. If I connect to the main server via it's actual name, I can hit the remote/linked server with no issue. However, if I connect to the main server using it's alias, connection to the remote/linked server fails with: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
The linked server is set up to use current security context and I'm not logging into the alias any differently that I do when using the actual server name.
Is there any way to find out the password for the remote login of the Linked server

I have a situation that I need to add a field to a table over linked server. The specifications of this is dynamic and it is being done in TQL / Stored procedures and this can not change. My code is generating the statement just fine and if I copy paste it to a new SSMS window and execute it WORKS.. The problem is I need to dynamically generate the statement (I am doing that just fine, I THINK). THEN I need to execute the statement IN THE SPROC, this part is not working.
Here is the code:
SET @AlterSQL = @DestinationServerName + '.[' + @DestinationDBName +'].' + @DestinationSchemaName + '.sp_executesql N'' ALTER TABLE '
+ @DestinationTableName + ' ADD ' + @TempColumn + ' int' + CHAR(39)
The above Creates this when I expose it via a PRINT statement:
addb15.[FSParallel].dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int'
After I create the statement I use:
EXEC @AlterSQL
And this returns the following error:

I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.
Sample Data:
CREATE TABLE #t (LoanID VARCHAR(5), BorrowerName VARCHAR(20), BorrowerOrder INT);
GO
INSERT INTO #t VALUES
('::E', 'John Smith', 0)
, ('::E', 'Jane Smith', 1)
, ('::E', 'Rob Jackson', 2)
, ('AF_CF', 'Sloan Burton', 1)

I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.
Attempt with CTE:
--With CTE
;WITH cte AS
(SELECT
Borrower1 = BorrowerName
, Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder)
, RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)
[code]...
Is there a better, cleaner way to do this? Or is the CTE the best way to go?
I have a 3rd party dashboard application that I can only use SQL authenticated logins to connect to the database.

When I login as a Windows auth user, I can successfully run the above query.
I noticed within the linked server's security definition that I cannot specify a windows auth user as the mapped Remote User or as the Remote login
I've tried creating a Credential object with the identity of the windows user and assign that object to the sql auth user but to no avail. I still get the same error

I have idea on SMK, DMK and symmetric and asymmetric keys. I have also idea on TDE. But Is there any way to encrypt all the records of all the columns of a table in a database? actually I need to encrypt the database. Someone .... thinks that when someone will write select query he will get the encrypted records. As per as I am concerned it is not possible. I can encrypt the specific column using symmetric or other keys...
Is there any software or any tool which will provide encrypted records of database?
With this query i get only the records i need, but i would like to output in this way
1 - 20
21 - 30
31 - 40
of course in the real environment the ID are not consecutive, this is just one example of data.
declare @temp table (ID int)
declare @i int = 1
while(@i<1000) begin
insert into @temp values (@i)
set @i=@i+1
end
select ID from (
select ID, row_number() over (order by ID)
as rn
from @temp
) q where (rn % 20=0) OR (rn % 20=1)
In Oracle when i create any procedure i define parameter datatype linked to under lying table.
For ex
create procedure testprocedure
(param1 customer.name%type,
param2 customer.salary%type )
Here i have defined param1 and param2 with datatype of name and salary of customer table respectively.
This way i do not need to worry about modifying param1 and param2 datatypes when datatypes of name & salary of customer table changes in future.
How can i accomplish this in SQL server.
I have a series of records based on empid where I want to identify the empid that may have discrepancies listed. I have some empids that are listed more than once and have different DOB's. In the example I am trying to Create a DOB_ERROR column and either say yes if the DOB doesn't match the other records in the file with the same empid.
SELECT
Empid,
DOB,
CASE WHEN DOB = DOB THEN 'No' ELSE 'Yes' END AS DOB_ERROR,

I have 2 tables with this schema
CREATE TABLE tableValues(

I want to update tableToUpdate in batches of 5000 per batch and set the lastenecryptionDT to null based on the the join to the tableValues using the column ENCRYPTIONID, and also output updated rows into another table. Incase I would need to do a rollback.
I have 5 columns in my database. 1 column is coming like a dynamic.
I want to convert records from rows to columns. Currently I have a data like this.
Race AgeRange Amount
W 17-20 500
W 21-30 400
W 31-40 200
A 17-20 100
H 41-50 250
H 51-60 290
So age range is not fixed and it can be any and I have one separate relational table for age range where it's coming from. Now I want to convert it into columns like
Race 17-20 21-30 31-40 41-50 51-60
W 500 400 200 0 0
A 100 0 0 0 0
H 0 0 0 250 290
How to fetch records which throws error?

* Here I have no clue in which column it is
* also dont know which row causes it
I have two tables that can be created with sample data using the DDL at the bottom of this post. What I'm looking to do is update the QtyReceived column in tblPurchaseOrderLineDetail from the Qty column in tblReceivedItems. However, the tricky part that I can't figure out is splitting these quantities out over multiple lines. I should only be allowed to receive up to the QtyOrdered column in tblPurchaseOrderLineDetail.
For a specific example from the sample data we'll look at PurchaseOrderDetailID 28526. From the tblReceivedItems, there are three records with quantities of 48, 48, and 20. From the tblPurchaseOrderLineDetail there are three records of QtyOrdered of 55, 45, and 20. What I would like to happen is fulfill the records in the tblPurchaseOrderLineDetail sequentially (essentially in order of ExpectedDate). So, the QtyReceived would be 55, 45, and 16 for the corresponding records. If there is already a quantity in the QtyReceived column, but it's less than the QtyOrdered column, the quantity needs to be added to the column (not overwritten).
DDL To CREATE Sample Tables and Data:
CREATE TABLE [dbo].[tblReceivedItems](
[ID] [int] IDENTITY(1,1) NOT NULL,
[PurchaseOrderDetailID] [int] NULL,
[Qty] [int] NULL)
SET IDENTITY_INSERT [dbo].[tblReceivedItems] ON
INSERT [dbo].[tblReceivedItems] ([ID], [PurchaseOrderDetailID], [Qty]) VALUES (1, 28191, 48)
