Inconsistent Linked Server Query Results
Feb 26, 2007
Hello,
I have a linked server named 'Charlie_File' to an Excel Workbook that I set up in SQLServer 2005 Management Studio. The workbook is on my local C drive. Sometimes, I get the results back that I expect when I run the following query;
SELECT * FROM OPENQUERY(Charlie_file, 'SELECT * FROM [Feb$]')
Sometimes, on subsequent runs of the above query, I get the following message;
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "Charlie_file" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "Charlie_file".
There seems to be about a minute or so of a delay before the query will run correctly on subsequent attempts. Is there a connection issue here where a connection blocks subsequent attempts to select the data within a specific time span?
Thank you for your help!

I am running SQL Server 7.0 on NT 4.0. I have created a simple query:
SELECT SUM(month1) As total_month1
FROM eac_manload
WHERE project_number = 8800
and dept IN (50,51,52,55,57,60,61,62,63,64,65,68,69)
I first time I run the query I get the correct result. Subsequent times that I run the query the result is 1 record with a Null value. The data has not changed. If I stop MSSQLSERVER and restart the service I get the correct result the first time and the Null value each time thereafter. Anybody out there with any idea of what is going on here? Any help will be appreciated!!

I have a problem retrieving data from a linked SQL Server 6.5 server in version 7. I have set-up the server as a linked server and most operations occur with no problem. With some tables, though, I get the following error when I attempt to query any column of data:
Server: Msg 7356, Level 16, State 1, Line 1
OLE DB provider 'SQLOLEDB' supplied inconsistent metadata for a column. Metadata information was changed at execution time.
This occurs consistently for a subset of tables. I cannot see any pattern to the configuration of these tables that would make them any different to those where a query succeeds.
Any ideas?
Regards

help...
i successfully linked the sybase database to sqlserver. at first i can select a record, after i execute the same statement the result become different. i was looking for answer in the web but i can't find one. can somebody help me...
i suspect that sqlserver cache the result.. so i try to create a view for sybase database table. when i select the view it gave me the complete result but when i rerun the statement again it became inconsistent.
is there a cache or something in sqlserver. if there is how can i clear it.. so i will always get the fresh copy of the result.

I have a lot of rows of hours, set up like this: 0745, 0800, 2200, 1145 and so on (varchar(5), for some reason).
These are converted into a smalldatetime like this:
CONVERT(smalldatetime, STUFF(timestarted, 3, 0, ':')) [this would give output like this - 1900-01-01 11:45:00]
This code has been in place for years...and we stick the date on later from another column.
But recently, it's started to fail for some rows, with "The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value".
My assumption is that new data being added in is junk. If I query for these values and just list them (rather than adding a column to convert them also) that's fine, of course. I've checked all the stuffed (but not yet converted - so 11:45 rather than 1145) output to see if it ISDATE(), and it is. There are no times with hours > 23 or minutes greater than 59 either.
If I add the CONVERT in, we see the error message. But here's the oddity, if I place all of the rows into a holding table, and retry the conversion, there is no error. It's this last bit that is puzzling me. Plus I can't see any errors in the hours data that would cause a conversion problem.
I've put the whole of this into a cursor to try to trap the error rows too, but all processes fine. Why would it fail if NOT in a cursor?

I am getting inconsistent results when BULK INSERTING data from a tab-delimited text file. As part of my testing, I run the same code on the same file again and again, and I get different results every time! I get this on SQL 2005 and SQL 2012 R2.
We have an application that imports data from a spreadsheet. The sheet contains section headers with account numbers and detail rows with transactions by date:
AAAA.1234 /* (account number)*/
1/1/2015 $150 First Transaction
1/3/2015 $24.233 Second Transaction
BBBB.5678
1/1/2015 $350 Third Transaction
1/3/2015 $24.233 Fourth Transaction
My Import program saves this spreadsheet at tab-delimited text, then I use BULK INSERT to bring the data into a generic table full of varchar(255) fields. There are about 90,000 rows in each day's data; after the BULK INSERT about half of them are removed for various reasons.
Next I add a RowID column to the table with the IDENTITY (1,1) property. This gives my raw data unique row numbers.
I then run a routine that converts and copies those records into another holding table that's a copy of the final destination table. That routine parses though the data, assigning the account number in the section header to each detail row. It ends up looking like this:
AAAA.1234 1/1/2015 $150 First Purchase
AAAA.1234 1/3/2015 $24.233 Second Purchase
BBBB.5678 1/1/2015 $350 Third Purchase
BBBB.5678 1/3/2015 $24.233 Fourth Purchase
My technique: I use a cursor to get the starting RowID for each Account Number: I then use the upper and lower RowIDs to do an INSERT into the final table. The query looks like this:
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericTable
WHERE RowHeader LIKE '____.____%'
Results look like this:
But every time I run the routine, I get different numbers!
Needless to say, my results are not accurate. I get inconsistent results EVERY TIME. Here is my code, with table, field and account names changed for business confidentiality.
TRUNCATE TABLE GenericImportTable;
ALTER TABLE GenericImportTable DROP COLUMN RowID;
BULK INSERT GenericImportTable FROM 'SERVERGeneralAppnameDataFile.2015.05.04.tab.txt'
WITH (FIELDTERMINATOR = ' ', ROWTERMINATOR = '', FIRSTROW = 6)
ALTER TABLE GenericImportTable ADD RowID int IDENTITY(1,1) NOT NULL
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericImportTable
WHERE RowHeader LIKE '____.____%'

Hi, have configured an ODBC linked server for an Adaptive Server Anywhere (ASA6.0) database.
I have to write a function (not a procedure) that receives a number (@Code) and returns 1 if it was found on a table in the linked server, or 0 if not. Looks very simple...
One problem, is that the queries on a linked-server must be made through the OPENQUERY statement, which doesen't support dynamic parameters. I've solved this making the whole query a string, and executing it, something like this:
SET @SQL='SELECT * FROM OPENQUERY(CAT_ASA, ''SELECT code FROM countries WHERE code=' + @Code + ''')'
EXEC sp_executesql @SQL
(CAT_ASA is the linked-server's name)
Then, i would use @@ROWCOUNT to determine if the code exists or not. But before this, a problem appears: sp_executesql is not allowed within a function (only extended procedures are allowed).
Does somebody know how to make what i want?? I prefer to avoid using temporary tables.
Thanks!

Hi,
I am building a report with a recursive hierarchy for drill-down purposes. The hierarchy is built by querying a SSAS OLAP cube and defining a details grouping for the table/matrix.
Every time I run the report one or more of the leaf members in the recursive hierarchy "jumps" up to the highest level. First I thought that this may be due to the fact that the leafs parents are not part of the returned dataset. However, the queries makes sense and the "offending" members does never contain any data (while the query should return only non empty members) which is why this is a very strange behavior. Furthermore, the "offending" member differs between different executions of the report, despite the fact that the parameters is exactly the same and the cube is untouched between executions.
I am actually pressing "View Report", waiting for the report to execute and when I press "View Report" again, the returned datasets seem to differ, yielding different "offending" members in the report.
When I run the queries individually in the Data-tab in BIDS, the returned datasets are always the same. Execution caching is turned off for the report.
Checking against SSRS's ExecutionLog, the RowCount for consecutive executions with the exact same parameters differ. For example, RowCount:
3094
3080
3079
3088
3087
Why does SSRS behave such inconsistently? Any tips or tricks?

I have a stored procedure (see below), in which I would like to check if the create an identity column and make it a primary key succeeded. I check @@error after the exec statement. This used to pick up an error if the table already had an identity column. It has stopped doing that. Why? And, if this is not the way to capture the error after the exec statement, how do I do it?

I'm testing some code to look up values from my database and update a specific field when certain conditions are met. I'm having trouble with some code that is giving me the results I expect when I submit one set of parameters, but is not finding anything in the database for another set, when I know the data exists.
Here's the code for my stored procedure, SP:
Code:
@flightid bigint,
@departuretime smalldatetime
SELECT flightid, flightno, departuretime, origincode, destinationcode
FROM flightschedules
WHERE flightid <> @flightid
AND departuretime = CONVERT(SMALLDATETIME, @departuretime, 120)
And here's the vbscript that calls it:
Code:
vOutboundID = 452
vReturnID = 453
'--- Get the flight details ---
strOrigin = "confirmflightdetails '" & vOutboundID & "';"
set rsOrigin = Server.CreateObject("ADODB.Recordset")
rsOrigin.Open strOrigin, objConn
response.write "origin " & rsOrigin("departuretime") & "<BR>"
strReturn = "confirmflightdetails '" & vReturnID & "';"
set rsReturn = Server.CreateObject("ADODB.Recordset")
rsReturn.Open strReturn, objConn
response.write "return " & rsReturn("departuretime") & "<BR>"
strGetOFID = "SP '" & vOutboundID & "', '" & rsOrigin("departuretime") & "';"
set rsOFID = Server.CreateObject("ADODB.Recordset")
rsOFID.Open strGetOFID, objConn
DO WHILE NOT rsOFID.EOF
response.write "OFNO " & rsOFID("flightno") & " " & rsOFID("flightid") & "<br>"
rsOFID.MoveNext
Loop
strGetRFID = "SP '" & vReturnID & "', '" & rsReturn("departuretime") & "';"
set rsRFID = Server.CreateObject("ADODB.Recordset")
rsRFID.Open strGetRFID, objConn
DO WHILE NOT rsRFID.EOF
response.write "RFNO " & rsRFID("flightno") & " " & rsRFID("flightid") & "<br>"
rsRFID.MoveNext
Loop
Here's the code for confirmflightdetails:
Code:
@flightid bigint
AS
SELECT flightid, flightno, departuretime
FROM flightschedules
WHERE flightid = @flightid
When confirmflightdetails is tested, I the proper results, as confirmed by the response.write statements:
4521092006-07-29 08:00:00
4531102006-07-29 12:05:00
I put the response.write statements and loops in so I could verify the functionality.
Here's what it produces:
out 452
ret 453
origin 7/29/2006 8:00:00 AM
return 7/29/2006 12:05:00 PM
OFNO 109 450
Here's what it should produce:
out 452
ret 453
origin 7/29/2006 8:00:00 AM
return 7/29/2006 12:05:00 PM
OFNO 109 450
RFNO 110 451
If I do this in query analyzer:
Code:
select flightid, flightno, departuretime
from flightschedules
where flightid > 449 and flightid < 454
this is what I get from the database:
flightid flightno departuretime origin destination
4521092006-07-29 08:00:00 A C
4501092006-07-29 08:00:00 A B
4531102006-07-29 12:05:00 C A
4511102006-07-29 13:15:00 B A
What I'm trying to do is look up the chosen flight, then find the flight with the matching origin/destination (the other flight leg) on the same day.
I can't figure out why it's working for one set of parameters and not for the other.
Thanks in advance for any help!

Firstly may I say that the sproc I am having problems with and the service that calls it is inherited technical debt from an unsupervised contractor. We are not able to go through a rewriting process at the moment so need to live with this if possible.
Background
We have a service written in c# that is processing packages of xml that contain up to 100 elements of goods consignment data. In amongst that element is an identifier for each consignment. This is nvarchar(22) in our table. I have not observed any IDs that are different in length in the XML element.
The service picks up these packages from MSMQ, extracts the data using XPATH and passes the ID into the SPROC in question. This searches for the ID in one of our tables and returns a bool to the service indicating whether it was found or not. If found then we add a new row to another table. If not found then it ignores and continues processing.
Observations
The service seems to be dealing with a top end of around 10 messages a minute... so a max of about 1000 calls to the SPROC per minute. Multi-threading has been used to process these packages but as I am assured, sprocs are threadsafe. It is completing the calls without issue but intermittently it will return FALSE. For these IDs I am observing that they exist on the table mostly (there are the odd exceptions where they are legitimately missing). e.g Yesterday I was watching the logs and on seeing a message saying that an ID had not been found I checked the database and could see that the ID had been entered a day earlier according to an Entered Timestamp.
So the Sproc...
USE [xxxxxxxxxx]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
[Code]....
So on occasions (about 0.33% of the time) it is failing to get a bit 1 setting in @bFound after the SELECT TOP(1).
The only suggestions I can make have been...
change @pIdentifier nvarchar(25) to nvarchar(22)
Trim any potential blanks from either side of both parts of the identifier comparison
Change the SELECT TOP(1) to an EXISTS
The only other thought is the two way parameter direction in the C# for the result OUTPUT. Not sure why he did it that way or what the purpose is.
I have been unable to replicate this using a test app and our test databases. Has observed selects failing to find even though the data is there, like this before?

I have a query that joins two large partitioned tables and depending on the values in the where clause, I can get dramatically different performance results.
The first query completed in around 7s and has 47,000 logical reads.
select mo.monitor_id,
mo.site_id,
mo.testtime,
sum(mo.NumBytes),
sum(mo.DNSTime),
sum(mo.ConnectTime),
sum(mo.FirstByteTime),
sum(mo.ContentTime),
sum(mo.RelocTime)
from monitor_raw mr(nolock), monitor_object mo(nolock)
where mr.monitor_id in (5339, 5341, 5342, 943842, 943866)
and mr.testtime between 'Oct 31 2007 3:00:00:000PM' and 'Nov 30 2007 3:00:00:000PM'
and mo.returncode = 200
and mr.site_id in (101,102,105,109,110,112,115,117,119,122,126,151,132,139,129,135,121,138,143,142,159,148,128,171,176,177,178,111,113,116,118,120,127,133,131,130,174,179,185,205,200,202,203,204,210,211,208,209,212,213,216,199,214,224,225,229,230,232,235,241,245,247,250,254,261,267,264,265,266,268,269)
and mr.escalationlevel = 0
and mr.monitor_id = mo.monitor_id
and mr.testtime = mo.testtime
and mr.site_id = mo.site_id group by mo.monitor_id, mo.site_id, mo.testtime
The second query takes 188s to complete and has 1.8m logical reads. The only difference between the two is the value of the monitor_ids in the where clause.
select mo.monitor_id,
mo.site_id,
mo.testtime,
sum(mo.NumBytes),
sum(mo.DNSTime),
sum(mo.ConnectTime),
sum(mo.FirstByteTime),
sum(mo.ContentTime),
sum(mo.RelocTime)
from monitor_raw mr(nolock), monitor_object mo(nolock)
where mr.monitor_id in (152682, 5339, 5341, 5342, 268080)
and mr.testtime between 'Oct 31 2007 3:00:00:000PM' and 'Nov 30 2007 3:00:00:000PM'
and mo.returncode = 200
and mr.site_id in (101,102,105,109,110,112,115,117,119,122,126,151,132,139,129,135,121,138,143,142,159,148,128,171,176,177,178,111,113,116,118,120,127,133,131,130,174,179,185,205,200,202,203,204,210,211,208,209,212,213,216,199,214,224,225,229,230,232,235,241,245,247,250,254,261,267,264,265,266,268,269)
and mr.escalationlevel = 0
and mr.monitor_id = mo.monitor_id
and mr.testtime = mo.testtime
and mr.site_id = mo.site_id group by mo.monitor_id, mo.site_id, mo.testtime
The two tables have clustered indexes on monitor_id, testtime and site_id. Comparing the execution plan, I can see why there is such a difference in performance. The second query performs a clustered index seek on the monitor_object table starting at the lowest monitor_id, testtime & site_id through the highest monitor_id, testtime & site_id. The first query performs a clustered index seek where the monitor_id, testtime and site_id equals the same values from the monitor_raw table.
My question is, how can I force the second query to use the same execution plan as the first so that I can get better performance?
One possible workaround that I could use is to execute five individual queries, one for each monitor_id and then union the results together but this would require significant code changes to my stored procs.
Thanks,
Tim

Greetings,
Facing a strange problem, but obviously not expected earlier on, I am trying to execute a stored procedure via ADO which refrences a linked server table and I get an error specifying
"
OLEDB provider SQLOLEDB does not contain table "<DatabaseName>"."<owner>"."<tableName>"
"
Has any one else encountered this problem before ?

hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!

Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist.
My current SQL statement is as follows.
SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))"
So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated.
Thanks,
James.

Hello,I have one simple query joining two tables with left outer join on 3fields and using MIN on two fields. These two tables have lot of dataabout 3 mil in total. I am trying to migrate db from MS Access to SQL2005. I get about 689000 rows in SQL Server, vs 863000 rows in MSAccess.SELECT T1.[MON], T1.[ANUM], T2.[ANUM], MIN ( T1.[OCD]), MIN(T1.[STATE]), T1.COUNTFROM T1 INNER JOIN T2 ON T1.MON = T2.MON AND T1.[OCD] = T2.[OCD] ANDT1.[STATE] = T2.[STATE]WHERE T1.[REASON] <'SOMETHING' AND T2.[REASON] <'SOMETHING'GROUP BY T1.[MON], T1.[ANUM], T2.[ANUM], T1.COUNTHAVING T1.[MON] <'-' AND T1.[ANUM] <'-'I have about 30 queries to migrate and I am sort of stuck. Does anyone have any idea ?JB

Greetings all,
I have successfully been able to use a SELECT query to see tables on a remote (Linked) server. Now, I want to be able to join those records with a WHERE clause to the same tables I have on my local database. The idea here is to be able to see current data on my local database(which is not current data), which resides in the remote database(which is current data). Here is what I have so far:
SELECT top 10 * from LinkServer.MC_Card.webuser.POS_TX
But, I'm not sure how to SELECT from two tables. Would I do a SELECT from the local database WHERE all records = records on the remote database?
Not sure how to do this. Is this what would be considered a Distributed Query? And how would I make this work with joins like the existing joins I have to the tables in my local database?
This is new territory for me. Sorry if this is such a newbie question.
Thanks,
Bruce

I'm using MS SQL Server Express and I've added a linked server. (I created the linked server by right mouse clicking on Server Objects, selecting SQL and entering the SQL2 as the name.) Now I'm trying to query a linked table. The following query works.
SELECT * FROM SQL2.PA.dbo.Counties
This one doesn't:
Select * from OPENQUERY(SQL2,"SELECT * FROM SQL2.PA.dbo.Counties")
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'SELECT * FROM SQL2.PA.dbo.Counties'.
Can you tell me why?

Hi guys I need some help connecting to a LINKED SERVER. I have setup the LINKED SERVER via Enterprise Manager. This is what I did. I know this is a difficult thing to explain so I will try my best and attempt to give you a good understanding of the scenario.
1. I have three servers named DEVUK, DEVUS and DEVASIA.
2. DEVUK I can connect to via my computer and contains a databases called GOD.
3. I went into DEVASIA server and went to Administrative Tools > New ODBC Connection and called it DEVASIAUK.
4. Setup everything in there and tested the connection which completed successfully.
5. I am now on my computer where I have connected to DEVASIA and gone into Server Objects > Linked Servers.
6. I created a new LINKED SERVER and under GENERAL TAB have stated DEVASIAUK and Provider as SQL Server.
7. Security I have used NT_AUTHORITYand option BE MADE USING THE LOGINS CURRENT SECURITY CONTEXT.
I have the SQL Command: SELECT * FROM DEVASIAUK ... tblLocalTable
Am I doing this right? Or am I missing something here? I am new to Linked Servers but it shows it is executing a query but then it says Login Failed.
Appreciate any help, thanks, Onam

Hello folks!
I have written a query that I need to save results of. Is there some statement that I can place at the top of my query (like we can do in Oracle through spool command) to specify the directoryfilename to save query results to? Eventually I need to schedule this to run daily via a DTS package.
Please let me know if you've come across this before?
Thanks so much!

I have a relatively simple SQL Server 2000 database which I amquerying from a VB.NET application. The query is very simple, such asSELECT * FROM tblSystems. Let's say there are 10 records in the tabletblSystems. I expect to get 10 records from this query, and sometimesdo. But for some reason, I start getting 0 records from my app. If Irun the same query in SQL Server's Query Analyzer, it works fine. IfI reboot my machine, then it seems to work fine for a while, thenstarts giving me bad results again. I am running my app on the samemachine as SQL Server, although I can connect to my database remotelythrough my app, and I get the same results either way. Anyone seenanything like this? Was this fixed in a service pack (I'm using SP1,and don't want to install a newer one unless it's a known fix)?Thanks,Andrew

I'm seeing some change in behavior for a query in SQL Server 2005 (compared to behavior in SQL Server 2000). The query is as follows:
------------
create table #projects (projectid int) insert into #projects select projectid from tblprojects where istemplate = 0 and projecttemplateid = 365
Select distinct tblProjects.ProjectID
from tblProjects WITH (NOLOCK)
inner join #projects on #projects.projectid = tblprojects.projectid
Inner join tblMilestones WITH (NOLOCK) ON tblProjects.ProjectID = tblMilestones.ProjectID
and tblProjects.projectID in (
select projectid
from tblMilestones
where (parent = 683691 AND PrimaryDate between '4/15/2006' and '4/22/2006' )
and enabled = 1 )
------------
This is dynamic SQL generated by the application when a user requests a report with variable parameters. It works fine in SQL Server 2000. It outputs 47 records which is correct.
In SQL Server 2005, for some reason, the DISTINCT keyword is behaving as a TOP operator and outputs just 1 record. (Results of Showplan Text at the end of this post).
If I modify the query even the slightest bit by:
1) Changing "where (parent = 683691 AND PrimaryDate between '4/15/2006' and '4/22/2006' )
and enabled = 1 )"
To " where (parent = 683691 AND PrimaryDate between '4/15/2006' and '4/22/2006' ) )
and enabled = 1 "
2) Changing " Select distinct tblProjects.ProjectID"
To " Select distinct tblProjects.ProjectID+''"
3) Removing the Distinct keyword, storing into a Temp table, then performing a distinct on the temp table
4) Adding: OPTION (FORCE ORDER)
5) OR completely fixing the query (remove redundant loops, etc)
...it works fine (outputs 47 records). It also works if I created new tables (eg. tMilestones instead of tblMilestones) and inserted about 10 records into each and ran the query referencing these new tables.
I reindexed the tables, updated stats, updated usage, ran DBCC FREEPROCCACHE, changed MaxDOP settings...nothing makes the query behave the way it does in SQL Server 2000 without modifying the query/adding the query hint.
Have you come across this? Any ideas on what might be causing the "TOP" operation. (Somewhat resembles the bug mentioned in this article: http://www.kbalertz.com/Feedback_910392.aspx - but this was apparently fixed POST-SQL Server 2000 SP4 - so has it not made it into SQL Server 2005 yet?).
I will appreciate any new insights you might have on this issue.
Thanks much,
Smitha

Is there a way to set four part reference used in distributed query to a short
name in local server, so for each query you do not have to type the LONG four
part ref. repeatedly to linked server objects ?
Thanks a lot.

I need to query a linked server (which is Oracle) with some parameters. When I try to use a four part SQL statement, it does not work. But when I try to use OPEENQUERY statement, it works just fine. Problem comes when I need to send some parameters with the OPENQUERY'S 'query' part.
For example, the following statement works just fine:
SELECT *
FROM OPENQUERY(OracleLinked, "SELECT ACCOUNTNUMBER, POSTINGDATE FROM ORA_SERVER.FINANCEENTRY WHERE DATEOFENTRY BETWEEN '2000.01.01' AND '2000.01.31'")
But If I try to use:
DECLARE @DynamicSQL VARCHAR(1000),
@StartDate VARCHAR(10),
@EndDate VARCHAR(10)
SET @StartDate = '2000.01.01'
SET @EndDate = '2000.01.31'
SELECT @DynamicSQL = "SELECT ACCOUNTNUMBER, POSTINGDATE FROM ORA_SERVER.FINANCEENTRY WHERE DATEOFENTRY BETWEEN '" + @StartDate + "' AND '" + @EndDate + "'"
--SELECT @DynamicSQL
SELECT *
FROM OPENQUERY(OracleLinked, @DynamicSQL)
it does not work.
Well, I did some research and found out that OPENQUERY does not accept variables for its arguments. See the link below:(http://msdn.microsoft.com/library/psdk/sql/ts_oa-oz_5xix.htm)
Then is there any way I can accomplish what I want to on the Remote server?
Thanks in advance for your help.

Hi,
I am now facing a problem related to the linked server. I created the connection between server A and B as linked servers. When I execute the following SQL statement on server A,
select * from B.database1.dbo.tableA where id ='12345'
I can get the results within couple of seconds. But the similar query would take several minutes if I switch the server name in the query from B to A and
run it on server B! The tables on server A and B actually have the same sizes and the same indexes.
Do you have any clues and suggestions on this issue?
Thanks in advance.

I have created a linked server using an ODBC connection to an Access database. The command I used for this was:
EXEC sp_addlinkedserver
@server = 'Testaccess',
@srvproduct = '',
@provider = 'MSDASQL',
@datasrc = 'test'
GO
where 'Testaccess' is the name of the linked server and 'test' is the name of the ODBC connection. [The ODBC connection stores the name of the Access datbase.]
I can run sp_tables_ex and view the table_schem, table_cat etc etc
BUT when I try to run a query on the linked server, I get the following message:
"7312 - Invalid use of schema and/or catalog for OLE DB provider '%ls'. A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog and/or schema."
I am attempting/using the following command specifying the linked server name.database name.owner.table name in the FROM clause:
select a.*
from testaccess.testdb.dbo.temptable a
Any ideas what I am doing wrong??
thanks
Jan
