SQL Server 2008 :: Extracting Data From Linked Server
Dec 17, 2010
I am using MS SQL 2008, and I am trying to extract data from a MySQL database. I am having trouble extracting the data I need.
In SQL Server management studio, I can see the linked server...I can browse the different databases on the server. I can see user and system tables in all of the databases.
When I try and query a linked table (select * from server.db.table) I get Invalid object name 'servername.databasename.tablename'.
When I try script the table.. right_click on the linked table, Script table as, Select to, New Query Editor window, I get an error '[servername].[databasename]..[tablename] contains no columns that can be selected or the current user does not have permissions on that object.'
This leads me to believe that it is a permissions problem, but if I have access to the MySQL database using MySQL and the same login/password) and can retrieve the data there, then I think my login credentials should be enough using MS SQL. I guess I think its odd that I could have enough credentials to get in and see table names, but not do a select against it.
I have the linked server connection created and works perfectly well. I mean I am able to see the tables while I am on my database.
how do I write a SQL statement to reference the linked server ?
I tried the following:
Select top 100 * from casmpogdbspr1.MPOG_Collations.dbo.AsaClass_Cleaned
Then I get the error message....
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI10" for linked server "casmpogdbspr1" does not contain the table ""MPOG_Collations"."dbo"."AsaClass_Cleaned"". The table either does not exist or the current user does not have permissions on that table.
I work in Healthcare IS for Company A, but Company B is hosting one of our EMR programs for us. This was done on purpose, so that whether a patient is seen at one or the other, their medical history is more complete. However, this puts all of the data that I need to get to on a server across town that I can only access via Sql Server Management Studio as a linked server.
Now, in some ways, the performance has been better than I expected, but sometimes it behaves very erratically. I am using OPENQUERY to handle all of the pulls, and am not joining to any local tables, in order to maximize efficiency.
Here is some of the code I run, and what happens:
SELECT * FROM OPENQUERY([linkedservername], ' SELECT * FROM Encounter_ItemChild
[Code] ....
***The above query was programmatically generated by taking the IDs from the second query, and packing as many into the IN condition as possible. Each statement could hold only about 900 IDs, so around 70 queries get built...however, each one returns the records in question in 1-2 seconds.
My main question is...if the second query pulls all IDs from Encounter in a few seconds, and that query is used in the first query's WHERE clause, why does it spin and spin, while manually throwing the IDs in instead runs almost instantly?
Using a 32-Bit SQL Server 2008 Express on my LOCAL PC. I downloaded the Advantage 8.1 OLE DB Provider and created a linked server to a REMOTE Advantage 8.1 database server. There is no data dictionary on the Advantage server.
Here is my linked server:
EXEC master.dbo.sp_addlinkedserver @server = N'1xx.1xx.xx.1xx', @srvproduct=N'Advantage', @provider=N'Advantage OLE DB Provider', @datasrc=N'1xx.1xx.xx.1xxeccET', @provstr=N'servertype=ads_local_server;tabletype=ads_cdx;'--tabletype=’ADS_ADT’ (this test works too) EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'1xx.1xx.xx.1xx',@useself=N'False',@locallogin=Null,@rmtuser='adssys',@rmtpassword=Null
Testing the link succeeds with above. Using “ads_REMOTE_server” instead of “ads_local_server” and the test fails. Here is my problem, using the following queries will not work. Perhaps it’s a permissions issue? When I specify my local credentials for the remote server in the linked server it still does not work.
SELECT * FROM OPENQUERY([1xx.1xx.xx.1xx], 'SELECT * FROM ActType')
OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx" returned message "Error 7200: AQE Error: State = HY000; NativeError = 5004; [Extended Systems][Advantage SQL][ASA] Error 5004: Either ACE could not find the specified file, or you do not have sufficient rights to access the file. Table name: ActType SELECT * FROM ActType". Msg 7321, Level 16, State 2, Line 2
An error occurred while preparing the query "SELECT * FROM ActType" for execution against OLE DB provider "Advantage OLE DB Provider" for linked server "1xx.1xx.xx.1xx".
A recent SharePoint upgrade has rendered several views obsolete. I am redefining them so that our upper level executive reports show valid data.(yes, I know that doing anything to sharepoint could cause MS to deny support, having said that, this is something I've inherited and need to fix, pronto) The old view was created like so:
USE [AHMC] GO /****** Object: View [dbo].[vwSurgicalVolumes] Script Date: 09/04/2015 09:28:03 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE VIEW [dbo].[vwSurgicalVolumes] AS SELECT
[code]....
As I said, this view is used in a report showing surgical minutes.SharePoint is now on a new server, which is linked differently (distributed?) I've used OPENQUERY to get my 'new' query to work;
SELECT * FROM OPENQUERY ([PORTALWEBDB], 'SELECT --AllLists AL.tp_ID AS ALtpID ,AL.tp_WebID as altpwebid ,AL.tp_Title AS ALTitle
[code]....
My data (ie surgical minutes, etc) seems to be in the XML column, AUD.tp_ColumnSet . So I need to parse it out and convert it to INT to maintain consistency with the previous view. How do I do this within the context of the view definition?Here is a representation of the new and old view data copied to excel :
can't format it to make it look decent. InHouseCases =2, InHouseMinutes=419, OutPatientCases =16, OutPatientMinutes=1230. This corresponds to the new data I can see in the XML column; 2.000000000000000e+000 is indeed 2 and 4.190000000000000e_002 is indeed 419.
I have two servers (lets call them sA and sB) connected from sA -> sB via a linked server (i.e. sA pulls data across from sB).
I'm building a temp table full of stock symbols on sA, and then I need to update some values on sA using content on sB. The tables on sB are very large (about 500m rows) so I don't want to pull even close to everything across the linked server. Ordinarily I'd do this by joining to the linked server table, but the target table needs to have nolock on it due to their high use.
update t set someValue = s.SomeValue from #myTab t inner join lnk_sB.xref.dbo.Symbols s with (nolock) on t.id = s.id
From reading around I gather that nolock doesn't work across linked servers. It was noted in another SSC article that you could use nolock by using an OPENQUERY, but then I can't join to my local temp table, and I end up pulling all .5B rows across the linked server.
Is there some way I can limit the content on sB by my temp table on sA but still use nolock?
Has anyone been able to solve the issue with setting up a package in EM, which connects to an Exchange(.edb) database and extracts the data into a SQL Server db. Previous message posts don't offer much insight. So far, all I have is using Access 2000, to connect & move the data, then extract from here. Thanks in advance for any help. BV
I have a form in Notes that is huge. I need to extract a part/field from that form into SQL SERVER. If I use NotesSQL Thru SQL DTSPackages, I am afraid it will run very long. Is there any other option on that?
Hey all, WE have a document management system where by Adminstrators can upload documents, once the document is uploaded the binary data is stored on in a folder on the web server. We used to stored the documents in the actaul db table, but we found that there were to many documents and it was using alot of space on db server. So my boss has decided we are now going to upload the binary data onto the web server. Currently we are donig this with new documents which have been added or documents which are gettinguploaded when reloading, but there are many documents in the db table which have not been updated and are still embedded in the db table. So i need to figure out how to go about copying the data storewd in the db table and storing it in web servers folder location. I've tried various things for a enitre day but im going round in circiles. MemoryStream mStream = new MemoryStream((Byte[])dtrResults["file"]); BinaryReader bReader = new BinaryReader(mStream); int intFileSize = (int)mStream.Length; Byte[] byteFile = (Byte[])dtrResults["file"]; i can get to this state but then how do i create a folder on the BinaryREader to then store the binary data of the file to the location. BinaryReader bReader2 = new BinaryReader(File.Open(strDocFolder + strSavedFileName, FileMode.Create)); int count2 = bReader2.Read(byteFile, 0, intFileSize); bReader2.Close();i've also tried this but when the file gets created in the folder there is no content. i do know that the file does contain content as ive tried this and downlaoding the file from that page acctually works string strContentTpe = WValue.WStr(dtrResults["contenttype"]); int intFileSize = VValue.VInt(dtrResults["filesize"]); / Byte[] byteFile = ((Byte[])dtrResults["file"]); //Downloads the data correctly Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("Content-Disposition", "attachment; filename="" + WValue.WStr(dtrResults["docfilename"]) + """); Response.AddHeader("Content-Length", WValue.WStr(intFileSize)); Response.ContentType = strContentTpe; Response.BinaryWrite(byteFile); I hope ive made some snese andthat someone can hlep me. Have a nice dayZal
I have a coworker who needs to extract data from Oracle into SQL Server 6.5 and Sybase as part of an interface that runs daily. How is the best way to do this?
I'm trying to extract some data from an XML column, into the demo below I would like to obtain the CommandText value but my attempts so far are in vain, I'm fairly sure its just a path issue in the .query command but I just can't seem to get it to work.
I am running an hotel application for all the bookings.
I would like to get all the data of all the guests that stayed in the hotel (name, stay duration and dates, payment, etc).However, the GUI would make me go over one booking at a time, which would take me forever.
The application has an SQL database locally on my computer.
Will I be able to use SQL server and extract all the guests data from the last year and export it into a file, e.g. A CSV file?
Below is the syntax I am using for creating Linked server from SQL Server i.e windows 2008 R2 standard to Postresql database running on Linux 32 bit Debian (Linux turtle 3.2.0-4-686-pae #1 SMP Debian 3.2.46-1+deb7u1 i686 GNU/Linux) and the version of Postresql is 8.3
/****** Object: LinkedServer [HGCDEV] Script Date: 09/15/2015 17:03:37 ******/ EXEC master.dbo.sp_addlinkedserver @server = N'HGCDEV', @srvproduct=N'', @provider=N'MSDASQL', @datasrc=N'172.16.20.159',@provstr=N'UID=web;PWD=dev123' /* For security reasons the linked server remote logins password is changed with ######## */ EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'HGCDEV',@useself=N'False',@locallogin=NULL,@rmtuser='web',@rmtpassword='dev123'
This the error I am getting " Cannot initializee the data source object of OLE DB provider "MSDASQL" for linked server "HGCDEV".
How to setup the linked server........... Below are the drivers installed on the SQL server
I am doing a project where I heed to extract data from a table in a sql server and then automatically create a bar chart with this data preferrably in PowerPoint (or excel). I was thinking myself that it may be done in vba/macro added to a button in powerpoint. If anyone knows how to do this i would be very grateful or if anyone know a useful website could they post it up.
We have oracle linked server created on one of the sql server 2008 standard , we are fetching data from oracle and updating some records in sql server . Previously its working fine but we are suddenly facing below issue.
Below error occurred during process .
OLE DB provider "OraOLEDB.Oracle" for linked server "<linkedservername>" returned message "". Msg 7346, Level 16, State 2, Line 1 Cannot get the data of the row from the OLE DB provider "OraOLEDB.Oracle" for linked server "<linked server name>".
I have an Excel sheet that is dynamically updated (through DDE) and I want to import this data to a table in SQL Server 2005. Using SQL Server Management Studio to configure an Excel data source as a linked server. (http://support.microsoft.com/kb/306397/EN-US/)
Following the first 5 steps should let me acces the table (but I cannot view the data in SQL Server 2005). However, I could not find how to export the data into an existing table. Does anyone know how or can give a pointer to document describing how to do this?
I am using Windows 2003 server and Sqlserver 2005 by the use of Linked server , I made a connection to Oracle 10g after that I am importing records from Oracle to sqlserver 2005. When I made tnsnames.ora in sql machine , it worked fine but when i am using tnsnames file from oracle server then i fiired importing procedure it returns below maintain error :
OLE DB provider "MSDAORA" for linked server "BI_ORACLE_LS" returned message "Unspecified error".
OLE DB provider "MSDAORA" for linked server "BI_ORACLE_LS" returned message "Oracle error occurred, but error message could not be retrieved from Oracle.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES" for OLE DB provider "MSDAORA" for linked server "BI_ORACLE_LS". The provider supports the interface, but returns a failure code when it is used.
I have a development and a production SQL server instance environment set up on 2 independent machines. Each machine is running Windows 2003 for an OS, while each server instance is version SQL Server 2005. On friday, I experienced difficulties querying one environment from the other through linked servers. I would get the error below: .
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "dev_server". The provider supports the interface, but returns a failure code when it is used
The linked servers had been previously set up and had been running without any issues. Dropping and recreating the linked servers did not help at all, and all attempts to google the error led to accounts of either SQL Server 2005-SQL Server 2000 procedures compatibility or 64 bit - 32 bit compatibily related errors. Neither of the two were relevant as both my environment have the same technology, both hardware and software.
Mysteriously, the linked server worked this morning without any issue at all. One co-worker suggests gremlins are at work, while another figures that my set up had 'checked out for the long weekend'. Unfortunately, neither explanation is plausible, so my quest to find out what could have gone wrong, and hopefully put preventitive measures in place for the future goes on. Does anybody have any idea what the issue could have been?
1) I can't get the 'copy database' function to work from SQL Server 2008 to SQL Server 2005. I connect ok. Everything goes to the last step and then it fails.2) I cant get a SQL server 2008 backup to restore on SQL SEerver 2005 either. The only way I know that works is to script the creation of all tables then export and import. This does work. How can I get the 'entire' database, structure and data, from 2008 to 2005? ThanksSQL newbie.
Production and development servers are on different domains and they do not trust each other. How do I import data from the table t1 from a database db1 in production and load it into table t1 inside database db1 in development?
I am task with identifying the source database name, id, and server name for each staging table that I create. I need to add this to a derived column on all staging tables created from merging same tables on different servers together.
When doing a Merge Join, there is no way to identify the source of data so I would like to see if data came from one database more than the other servers or if their are duplicates across servers.
The thing that bugs me about SSIS Data Flow task is there is no way to do an easy Execute SQL Task after I select my ADO.NET Source to get this information because my connection string is dynamic and there is no way of know which data source is being picked up at runtime.
For Example I have Products table on Server 1 and 2:
Server 2 has more Products and would like to join the two together to create a staging table.
Hi , On my Desktop i registered Production Server in Enterprise Manager on that Server if i go to SecurityLinked Servers There is another Server is already mapped, when i am trying to see the Tables under that one of the Linked Server i am getting the Error message saying that "Error 17 SQL Server does not exist or access denied"
if i went to Production Server location and if i try to see the tables i am able to see properly, no problems why i am not able to see from my Desk top i am using the sa user while mapping the Production Server on my DESKTOP using (ENTERPRISE MANAGER)
And i check the Client Network Utility in the Alias using Named Pipe only, i changed to TCP/IP still same problem What might the Problem how can i see the Tables in Linked Server from my DESKTOP
I need to create a function that replaces the data in a column with an 'X' based on the LEN of the data in the column. I created one that does a replacement, but it fills the column based on the max data length, and not the current length of the string or integer. An example of what I'm trying to accomplish.
Original data in a varchar(30) column: thisisavalue thisisanothervalue thisisanothervalueagain shortval
replaced with xxxxxxxxxx xxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx xxxxxxx
My current function is replacing the data like this: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
