I've connect some .DBF file to SQL server 7 with linked server option. My table have about 200.000 records. I've tried with ODBC and Jet 4.0 option (found in www.mssqlserver.com) but I've very slow response if I use a "where" in the select instance.
In fact I've the response after 10 seconds and during this seconds the processor go to 100%.
Does anyone found a most speed way to do this?
Thanks,

Please anybody help me.
Can't get oledb for odbc work.Need an explanation what to put in each field of linked server properties General tab to get connected. Have ODBC server DSN working fine with Crystal reports.
Did this:
exec sp_addlinkedserver @server = 'ODBC_TEST' ,
@srvproduct = 'dBase',
@provider = 'MSDASQL',
@datasrc = 'DB4_GBS'
GO
-- Adding linked server login:
EXEC sp_addlinkedsrvlogin 'ODBC_TEST', 'false', 'sqlLogin', 'sqlpassword', NULL
Getting error : datasource name not found and no default driver specified.
I also attempt to create OLEDB ODBCless link and can't do it because after that I have to change path in TEMP and TMP variables and restart db, but I cann ot restart the server.
:eek:
I am trying to create a linked server to some dbase 5 tables. I have read several other posts about using the OPENROWSET option and that does work however, I would like to be able to create a linked server for easier access.
End Goal: I am developing an ASP based app that needs to join a DB5 table to a SQL table.
Any help on the linked server properties in Enterprise Manager for dbase5 or on the proper sp_addlinkedserver function for dbase5 would be highly appreciated.

Hi,
I am trying to use linked tables to connect SQL Server 2000 to a legacy system using dbase III files. (I need real time read only access to these files)
I have created a linked table from SQL server to a folder on the C drive which contains the dbase III files, using an ODBC DSN which uses "Microsoft dbase driver (*.dbf)". DSN tested successfully using Excel. Linked server connection is then created using "Microsoft OLE DB Provider for ODBC drivers".
The dbase tables appear OK in Enterprise manager, but I cannot get a query to work in SQL Anayzer, using the 4-part name syntax.
My query is just :
SELECT * FROM LinkedTable...customers
Error message is "Invalid schema or catalog specified for provider 'MSDASQL'". Now I am pretty sure dbase files do not support any sort of schema / catalog set up, so I suspect SQL Server is looking for something it is not going to get.
One clue might be that in Enterprise manager, under the catalog column, I get the pathname to the dbase file, ie c:customers.dbf, which I cannot enter in the 4-part syntax.
Any suggestion welcome !!!
I need to push 40k rows daily to an Oracle database. I am on a Win2k Pro box with the 8.1 client and ADO 2.6 loaded. I've configured the linked server with the Oracle as well as the Microsoft provider and it takes over a minute to push just 24 rows, less than 100 bytes each, at it. Any suggestions?

View 2 Replies View RelatedHi i have a sql server instance on my system and it is linking into an oracle database on another server. When i run queries against this other server...it takes forever...
However, when i use access, and link the table and run the same query against the oracle database...it runs immediatly.
I am very confused as to why there would be such a performance difference and why sql server would run so slow.
I am wondering if it has something to do with the way i configured the linked server. there are several options that I didn't know what they meant.

Hello,
I have 2 servers (say MAINSRV e SECSRV) running SQL2000 Standard SP3 on Windows 2000 Advanced within a NT (!) domain and each server is linked to the other.
My problem is that if I run a query returning few dozens of rows like:
SELECT * FROM MAINSRV.DbName.dbo.TblName TBLA
WHERE Fieldx = 'anyval'
from a client connected to the SECSRV server, it takes something like 35 minutes to complete, while the same query completes in no time when run on clients connected to MAINSRV.
Even the simplest SELECT Count(*) FROM... takes more than one minute from SECSRV while completing in a fraction of second from MAINSRV.
I tried to change the linked server security options (SQL/Windows), but the remote query remains slow.
There are no locks active on the table, both the servers have almost no load (CPU less than 10%, when tested) and the query returns just a few KBytes, so communication overhead will not be the problem.
Any suggestions will be very appreciated, thank you!!!
Hello can some one explain this to me and give me some advice. I have sqlserver1 and sqlserver2 I have a linked server set up [ipaddress] on both servers. When I pass a variable to the stored proc or the query it takes up to 20 seconds to return 1 row but if I replace my varibles like email='sqlboy@coxnet' and firstname='ted' and lastname='clien' it returns the one row im looking for in about 2 seconds but if I pass email =@email ,fname=@fname,lname=@lname I get the 20 second thing. The query is a stored proc being called from an asp app. I get the same results when I run this in query analyzer.
Here is the query.

I am using two almost idential laptops, one with XP and one with Vista, the only differences is that the XP laptop has 1G of RAM and running Office XP and the Vista has 2G RAM and is running Office 2007.
I have a MS Access database that has linked tables to a SQL Server 2000 database. The performance of the Access database on Vista is 5-10 times slower on the Vista machine. Just flipping through records or opening forms can take 5 - 15 seconds on the Vista machine while the XP machine takes 1 sec or less.
What gives? I looked at the CPU performance and the network performance while the Access database was busy flipping through records, the network traffic was < 2% and the CPU would spike to 40% on one of the CPUs (dual core) but would remain under 5% most of the time.
I also previously had Office XP installed on the Vista machine and it had the same performance issue so bought and install Office 2007 on the Vista machine and it did not solve the problem.
It seems that Vista is doing something that is slowing down Access with linked tables. Is this a issue between Vista and using an ODBC connection to SQL Server?
Thanks in advance for any help on this
In an ASP, I have a dynamically created SQL statement that amounts to "SELECT * FROM Server1.myDB.dbo.myTable WHERE Col1 = 1" (Col1 is the table's primary key). It returns the data immediately when executed.
However, when the same record is updated with "UPDATE Server1.myDB.dbo.myTable SET Comments = 'blah blah blah' WHERE Col1 = 1", the page times out before the query can complete.
I watched the program in Profiler, and I saw on the update that sp_cursorfetch was being executed as an RPC once per each row in the table. In a table of 78000 records, the timeout occurs well before the last record is fetched, and the update bombs.
I can run the same statements in Query Analyzer from a linked server and have the same results. The execution plan shows that a Remote Query is occurring on the select that returns 1 row, and a Remote Scan is taking place on the update scanning 78000 rows (I guess this is where all the sp_cursorfetch calls are happening...?).
How can I prevent the Remote Scan? How can I prevent the execution of the RPC sp_cursorfetch for each row in the remote table?
Thank you!
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!
I previously posted re. this, but thought I'd try again with a summary offacts.I have an Access 2000 MDB with a SQL Server 7 back end. There is a view thatis linked to the database via ODBC and has been in place for several yearswithout any performance problems.Recently I added a couple of fields to the output of the view, and it becamevery slow when scrolling. When just opened in the database window, thelinked view takes about a second to scroll down one screen. When opened inthe form (in Continuous Form view), it takes about 2-3 seconds. It used toscroll just about instantaneously.I tried removing the few fields I added to restore the view to its previousform, but it had no effect. The view was still much slower than it had been.The total number of records returned from the view is about 1300, so it'snot a large number of records. The view has about 25 fields.I found that when I link the view in the MDB without specifying a uniqueindex, it scrolls very quickly -- almost instantaneously. But when I specifythe unique index, it is slow. Since the view needs to be edited, it needsthe unique index defined.As noted, it's been in place for years, with a unique index defined, yetwithout the slowness. Any ideas as to what might have caused this and whatmight be done would be appreciated. I've included the SQL for the viewbelow.Thanks,NeilSQL FOR MAIN VIEW:SELECT INVTRY.[Index], INVTRY.TITLE, INVTRY.AUTHILL1,INVTRY.attFirstEdition, INVTRY.attSigned,ISNULL(INVTRY.attSignedPD, ' ') SignedCond, INVTRY.YRPUB,INVTRY.PRICE, INVTRY.Web, INVTRY.Status,INVTRY.WebStatusPending, INVTRY.ActivateDate,INVTRY.DeactivateDate, INVTRY.WebAddedBatchID,INVTRY.AllowDuplicate, INVTRY.WebAction,INVTRY.WebActionPending, INVTRY.DateModified,INVTRY.DateWebActionApplied, INVTRY.JIT, INVTRY.MImage,INVTRY.HImage, INVTRY.AdCode,CASE WHEN INVTRY.WebAddedBatchID IS NOT NULLTHEN - 1 ELSE 0 END AS OnWebFROM vwInventory_Dupes INNER JOIN(WebStatus INNER JOIN(INVTRY INNER JOINtabStatus ON INVTRY.Status = tabStatus.Status) ONWebStatus.WebStatus = INVTRY.Web) ON(vwInventory_Dupes.YearPub = INVTRY.YRPUB) AND(vwInventory_Dupes.SignedCond = ISNULL(INVTRY.attSignedPD,' ')) AND (vwInventory_Dupes.Signed = INVTRY.attSigned) AND(vwInventory_Dupes.FirstEd = INVTRY.attFirstEdition) AND(vwInventory_Dupes.Author = INVTRY.AUTHILL1) AND(vwInventory_Dupes.TITLE = INVTRY.TITLE)WHERE (((tabStatus.ForWeb) = 1) AND ((WebStatus.IncludeDupe)= 1))SQL FOR vwInventory_Dupes:SELECT INVTRY.TITLE, INVTRY.AUTHILL1 Author,Cast(attFirstEdition AS tinyint) FirstEd,Cast(attSigned AS tinyint) Signed,ISNULL(INVTRY.attSignedPD, ' ') SignedCond,INVTRY.YRPUB YearPubFROM WebStatus INNER JOIN(INVTRY INNER JOINtabStatus ON INVTRY.Status = tabStatus.Status) ONWebStatus.WebStatus = INVTRY.WebWHERE (((tabStatus.ForWeb) = 1) AND ((WebStatus.IncludeDupe)= 1))GROUP BY INVTRY.TITLE, INVTRY.AUTHILL1,Cast(attFirstEdition AS tinyint), Cast(attSigned AS tinyint),ISNULL(INVTRY.attSignedPD, ' '), INVTRY.YRPUBHAVING (((COUNT(INVTRY.[INDEX])) > 1))

Hi,
I have used the backup tool in MS Access 2000.ADP many times
To make a nice backup of my adp Projects server objects(tables & data) that
I have in my MS SQL Sever 7.0 dBase. and then have successfully restored them back to the same computer that I have backed them up to. .
But now I need to transfer server SQL 7.0 DAT backup files over to two other types of computer setups..
I need to transfer these files and import or restore them onto another
computer that has MS Access 2000 and SQL 7.0 on a NT Server 4.0 platform and
also to a computer that has MS Access 2000 and MSDE on a win98 platform..
Have tried many different things but cannot seem to find a way to transfer or restore the SQL 7.0 DAT files to a different named dbase NT server with SQL 7.0 or to a win98 client with a named dbase on a MSDE file. the ADP client portion is just a simple file transfer but these SQL Server 7.0 DAT backup files... argh!
I am completely stumped even after trying many things and consulting the SQL
server manual.

The problem is when I try to include tables from the subfolders, the compiler send me a syntax error in the FROM Clausule
I Allready try this.
SELECT products.id, products.descri, condition.discount from products, clientscondition where products.line=condition.line
SELECT producst.id, products.descri, clientscondition.discount from products, clientscondition where products.line=condition.line
SELECT products.id, products.descri, condition.discount from products, condition in 'clients' where products.line=condition.line
SELECT producst.id, products.descri, clientscondition.discount from products, 'clients'.condition where products.line=condition.line
And many other different combinations. I would like to be helped if you know the correct syntax or a link where i can consult the syntax for VB.net and dbase with several folders
Another option a tried is having a query from 2 different datasources, but I don´t know how to make a reference to the 2 sqldatassources in a new one to be linked to the gridview

I am searching for a better way to move data from DBase3 files into SQL Server 2k. The Dbase file has approximately 2 million records and after applying a SELECT statement to retrieve the data I need to move, there are still over 600,000 records. To move this data I have used DTS (data pump) to transform the data- THIS IS UNBEARABLY SLOW. Next, I created an exe to transform the data to a flat file and then used BULK INSERT to copy the data. The exe is slow, but the BULK INSERT is fast. I have moved the source and destination to the local Server to increase performance, but with little imporvement.
My question:
Is there a better way to move large amounts of data from DBase3 files to SQL Server without waiting 38 hours to move 600,000 rows? Thanks for your help.
