Derived Tables Are UPDATABLE Or NOT ????
Sep 28, 2007
Hi,
In the SQL92 Specifications i read the foloowingf statement...
"All base tables are updatable. Derived tables are either updatable or read-only. The operations of insert, update, and delete are
permitted for updatable tables, subject to constraining Access
Rules. The operations of insert, update, and delete are not allowed
for read-only tables."
But i am concentrating on the below line from the above written lines,
"Derived tables are either updatable or read-only."
I want to ask that is derived tables are updatable or not??? if yes then how,???i tried the following querry but its not working...
Code Block
Update (select * from test1) AS de SET id=0
????

Has anyone seen this error? It comes up when my app executes a select statement via linked server (from MSSQL 2000 to 2005) the second time it runs. It's basically a timed poll of tables in the remote database. It works once but the second time it executes I get the error from the remote db, it's just a select but I guess the cursor is still open so it can't run again. After the exception the select will run again, once and it just repeats. I have researched it a little and it looks like it mostly has to do with the isolation level of the transaction. Unfortunately based on the componet being used to access the database I don't beleive I have the ability to use transact SQL to call the isolation level (s) listed.
Here's the weird part though, at another site the same scenario is running fine. Same primary and remote db versions of MSSQL as well as the application and it runs fine. I guess my question is what type of setup parameters that may be defined in MSSQL 2005 for the remote database might make it behave in this manner in one instance and not the other? TIA in advance for any thoughts/assistance.

I got an error as follows:
Derived table 'A' is not updatable because a column of the derived table is derived or constant.
when I tried to run this query:
update A set MonthsUnbilled =99999888
FROM (select MonthsUnbilled from dbo.vw_MasterView
WHERE (RecordID =8377396)) A
This is a simplified query in order to pinpoint the culprit. I know I don't need to use a derived table if the real query is this simple.
Thanks in advance!

Hello,We are researching whether the following scenario would be possible:In an upcoming application release, we have to move some tables (Logtables, look up tables, and a couple of secure tables) from database Ato database B.Rather than wait and do everything all at once, and have no roll-backplan should it fail, we'd like to create database B now, and startmoving those tables one by one over to it.To ensure compatibility with the existing code-base, we'd like todetermine whether we can use updatable views to allow the current codeto continue to run against the existing DB.Essentially, we would do this:Given a table named LogTable In database A, we'd copy all ofLogTable's data to database B. (We'd look at the transaction log tocopy any changes made on rows modified after copying started.)Then, we'd turn off the site for a few moments, and:In database A, we'd rename LogTable to LogTable-Old, and create a viewcalled LogTable which points to DatabaseB.dbo.LogTable.When we turn the site back on, updates and selects to LogTable wouldphysically pull from database B from now on.I have already verified that performing selects and updates against aview that refers to another physical database actually does work inSQL 2K5.My question is are there any pitfalls or things we should be aware ofthat anyone else has experienced trying to do something like this?Does it sound feasible?Thank you,Josh

Hi
This is for Sql Server 2000.
I get the following error :
View or function 'PS_EMPLOYMENT' is not updatable because the modification affects multiple base tables.
Sql is as follows:
INSERT INTO PS_EMPLOYMENT(EMPLID,EMPL_RCD,PER_ORG,BENEFIT_RCD_NBR,HOME_HOST_CLASS,OWN_5PERCENT_CO,
SECURITY_CLEARANCE,NEE_PROVIDER_ID,POSITION_PHONE,BUSINESS_TITLE,REPORTS_TO,
SUPERVISOR_ID)
VALUES('000004', 0, ' ', 0, 'M', 'N', ' ', ' ', ' ', ' ', ' ', ' ')
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Searching the KB i only found links to SP1 and SP3, the server is already at SP3.
BOL says the following:
SQL Server 6.x :
Updatable views were restricted to modifications that affected only one table
SQL Server 2000:
Updatable views can modify more than one table involved in the view. The DELETE, INSERT, and UPDATE statements can reference a view as long as SQL Server can translate the user's update request unambiguously to updates in the base tables referenced in the view's definition.
So why can this view not be updated in SS2000 SP3 ?
Here is a copy of the view defintion:
ALTER VIEW PS_EMPLOYMENT
(EMPLID, EMPL_RCD, PER_ORG, BENEFIT_RCD_NBR, HOME_HOST_CLASS, LAST_DATE_WORKED, HIRE_DT, REHIRE_DT,

LAST_VERIFICATN_DT, EXPECTED_RETURN_DT, LAST_INCREASE_DT, OWN_5PERCENT_CO, PROBATION_DT,

I have read that I need to add an instead of trigger. I have no idea how to do this. I am basicaly trying to update at the moment but will also need to insert later.
From the code in VWD2008 I only get the error when i include this info here: When i press update and these below are included in the update statement then i get the error.

We are planning to upgrade. We are using Sql 2008R2 now. Which is the better option migrating to SQL 2012 or migrating to 2014?I am thinking 2014 has memory optimized tables and updatable column stored index. So it is better option.

View or function 'MutualFund' is not updatable because the modification affects multiple base tables.
I get the above error when i try to delete rows from a view.
i tried the following code with a table. it works perfectly. i want the same behaviour for a view.
can anyone help.
Delete MutualFund
from MutualFund inner join MutualFund_history
on MutualFund.SecurityID= MutualFund_history.SecurityIDwhere MutualFund.MorningstarCategoryID=MutualFund_history.MorningstarCategoryID and
MutualFund.MorningstarAssetClassID= MutualFund_history.MorningstarAssetClassID and
MutualFund_history.insertdt =(Select MAX(DsegLastUpdated) from Timestamp_History(nolock))
"MutualFund" is a view.
if it were a table, the above works well. but how can i simulate the same effect for a view.
any help will be greatly appreciated.
thanks

Hi. We have to create an export from our system to be imported into another system. To get the data out we need to create some SQl but we're struggling a bit.
I presently have the following code
SELECT ProSolution.dbo.StudentDetail.RefNo, ProSolution.dbo.StudentDetail.FirstForename, ProSolution.dbo.StudentDetail.Surname,
ProSolution.dbo.StudentDetail.MobileTel, ProSolution.dbo.StudentDetail.RestrictedUseIndicatorID, ProSolution.dbo.Enrolment.CompletionStatusID,
ProSolution.dbo.Offering.Code
FROM ProSolution.dbo.StudentDetail INNER JOIN
ProSolution.dbo.Enrolment ON ProSolution.dbo.StudentDetail.StudentDetailID = ProSolution.dbo.Enrolment.StudentDetailID INNER JOIN
ProSolution.dbo.Offering ON ProSolution.dbo.Enrolment.OfferingID = ProSolution.dbo.Offering.OfferingID
WHERE (ProSolution.dbo.StudentDetail.AcademicYearID = '06/07') AND (ProSolution.dbo.StudentDetail.RestrictedUseIndicatorID = '9') AND
(ProSolution.dbo.Enrolment.CompletionStatusID = '1')
The above code returns the data one line per course but we need it to be one line per student with all their courses on one line too, like follows.

This is kind of what I'm trying to do in my MS SQL 2000 query. ShouldI be able to reference s1.col1 inside the 2nd derived table?I'm getting 'Invalid column name col1' and it's coming from the 2ndderived table (I've commented out other refs to just it to check).Maybe I need to use a temp table instead.SELECT s1.col1,(SELECT * FROM(SELECT COUNT(zzz) AS SomeTotalFROM tab1WHERE s1.col1 = zzz)) AS RowCount) /* error here */FROM(SELECT col1 FROM table) AS s1Thank you!

Hi!I want to return a derived table along with 4 simple tables in a storedprocedure as follows:Input parameter: @FtNum (==Order Number, selects one Order and allassociated data)Table 1: OrdersTable 2: ItemsTable 3: InstancesTable 4: StockDetailsDerived Table: for each Item that requires stock items, 1st columnshould receive the ItemNo (from Items), subsequent columns should receive thedetails from StockDetails via the common key field 'StockCode'.I have so far used a 'Fetch' cursor to find all occurrences of a StockCodewithin the Items table, but have been unable to figure out how to first addthe ItemNo into the temporary table.Code is as follows:... build #tmp_StockDECLARE stock_cursor CURSOR FORSELECT StockCode, ItemNoFROM ItemsWHERE FtNum = @FtNumORDER BY ItemNoOPEN stock_cursorFETCH NEXT FROM stock_cursorINTO @StockCode, @ItemNoWHILE @@FETCH_STATUS = 0BEGININSERT INTO #tmp_Stock-- wish to insert ItemNo = @ItemNo here --SELECT *FROM ControlledStockWHERE StockCode = @StockCodeFETCH NEXT FROM stock_cursorINTO @Stockcode, @ItemNoENDOf course there may be a much simpler way to do this!Your help would be greatly appreciated either way.--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200510/1

Hello.So the scenario is a little complicated.I am joining two tables.Table 1 is derived; it has one row; it has a column based from newid()Table 2 joins to table 1 and reuses the newid() value from table 1 in table 2's rowsBecause there is only one row in Table 1, the value of newid() REPEATS in Table 2The bug is that the NewId() value from Table1 is REGENERATED with every Table 2 record.I created a blog about this because it takes a code sample to demonstrate:http://jerrytech.blogspot.com/2008/04/sql-2005-tsql-bug-with-newid-in-derived.html
Have a nice day;

Two point to discuss
1) Temp table, variable table and derived tables,
they all seem same to me. Is there any big difference among them.
Also, if I do have the tables avaiable, so now I don't think I have to create any of the temerory tables,
since I can use the
WITh mystatement ( )
Select * from mystatmment
I think if I have to use any of the temperory tables , only time when I have to just create some tables to test some values on in it rather then using the real table in the database.
2) And not only that I use the CTE for that but for any sub query whereever apply, i would like to forget about the IN, Exit or = in the correlated queries but would use whereever I can use the "Joins"
I would like other point of view on that.
Thanks

create multiple INNER JOIN on derived tables as I have written below or use a #temp table for all derived tables and use them into JOIN. This below query is also very hard to understand what is going on .
CREATE TABLE #Temp
(
NumPlayers INT,
ModuleID INT,
ClientId INT,
ASF_Version VARCHAR(10),
ASF_VersionHead INT

Relative SQL newbie here......this is probably easy, but....Lets say I have a table (MainTable) that stores a list of input table names,a primary key (PKey), and a field called "Configured" for each one. Each ofthese input tables also contain a field called "Configured", which is set totrue or false in another process based on an OrderNumber. (So an order'sinputs are stored in several input tables, and the MainTable is a summarytable that shows which input tables have been configured for any givenOrderNumber).What I need to do is open each input table, and look for a record containinga specific OrderNumber and where Configured=true. If a record is found, Ineed to update the Configured field for that table in the MainTable, andthen move on to the next sub-table.The way I'm doing it now is with simple SQL and loops. Here is the basiccode (ASP):*****************************************OrderNumber = "562613" ' the current order that is being processed' reset all configured flagssql = "UPDATE MainTable SET Configured = 0"conn.execute sql, , &H00000080' get list of all tablenamessql = "SELECT InputTableName, PKey FROM MainTable WHERE InputTableName <>'---'"set rsTableNames = conn.execute(sql)while not rsTableNames.eof' test each input table for configured flagsql = "SELECT Configured FROM " & rsTableNames("InputTableName")& _" WHERE Configured = 1 AND OrderNumber = '" & OrderNumber &"'"set rs = conn.execute(sql)If Not rs.EOF Then' update the main tablesql = "UPDATE MainTable SET Configured = 1 WHERE PKey='" &rsTableNames("PrimaryKey") & "'"conn.execute sql, , &H00000080end ifset rs = nothingrsTableNames.movenextwend*****************************************There has to be a faster way.. I think.... maybe something that could bewritten as a stored procedure? I use a similar technique in a couple ofother places and it's a bit of a performance hit, especially as the numberof input tables grows.TIA!Calan

I am using derived tables to Page data on the SQL Server side.I used this link as my mentor for doing paging on the SQLServerhttp://msdn2.microsoft.com/en-us/library/ms979197.aspxI wanted to use USER PAGING, thus I used the following code:CREATE PROCEDURE UserPaging(@currentPage int = 1, @pageSize int =1000)ASDECLARE @Out int, @rowsToRetrieve int, @SQLSTRING nvarchar(1000)SET @rowsToRetrieve = (@pageSize * @currentPage)SET NOCOUNT ONSET @SQLSTRING = N'selectCustomerID,CompanyName,ContactName,ContactTitle from( SELECT TOP '+ CAST(@pageSize as varchar(10)) +'CustomerId,CompanyName,ContactName,ContactTitle from( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM Customers as T1ORDER BY contactname) AS T2 ORDER BY contactname DESC ) AS T3)As T4 ORDER BY contactname ASC'EXEC(@SQLSTRING)RETURNGOWhen I use this. Assume that the Total records returned by the SQLquery is 1198.Thus when I am on Page1 the above Stored Proc (SP) willreturn the first 1000 records.This works absolutely fine.Now I am on Page2, now I need to retrieve only the remaining 198records.But if I use the above SP, it will return the last 1000records.So to tweak this I used the following logic to set the@pagesize variable:Declare @PageCount intselect @PageCount = @TotalRows/@PageSizeif @currentPage @PageCount SET @PageSize = @TotalRows%@PageSizeSince I am on Page2 the above logic will set the PageSize to 198 andnot 1000.But when I use this logic, it takes forever for the SP toreturn the 198 records in a resultset.However if the TotalRows were = 1800, and thus the PageSize=800 orgreater, this SP returns the resultset quickly enough.Thus to get over this problem I had to use the other logic i.e. usingApplication Paging (i.e. first storing the entire result set into aTemp table, then retrieving only the required records for the PAGE)Can anyone suggest what is wrong with my user paging logic?????TIA...

( Please see the thread BELOW)I have a question on this, if someone can help me with that it will begreat.In my SQL query that selects data from table, I have a where clausewhich states :where PermitID like @WorkTypeorder by WorkStart DESC@WorkType is a input parameter to the Stored proc and its value is'01%'When I use the above where clause, all the Sorts in the ESTIMATED QueryExecution plan show me a COST of 28%.However if I change the query manually to say:where PermitID like '01%'order by WorkStart DESCThe COST of the Sort (in ESTIMATED Query Execution plan) reduces to 2%and at the beginning of the PLAN, there is a Bookmark Lookup whichincludes the above where clause.Whereas with the FIRST example , the BookMark Lookup in the beginningdoesn't show that where condition.Can anyone help me better understand this anomaly?TIA=====================================I am using derived tables to Page data on the SQL Server side.I used this link as my mentor for doing paging on the SQLServerhttp://msdn2.microsoft.com/en-us/library/ms979197.aspxI wanted to use USER PAGING, thus I used the following code:CREATE PROCEDURE UserPaging(@currentPage int = 1, @pageSize int =1000)ASDECLARE @Out int, @rowsToRetrieve int, @SQLSTRING nvarchar(1000)SET @rowsToRetrieve = (@pageSize * @currentPage)SET NOCOUNT ONSET @SQLSTRING = N'selectCustomerID,CompanyName,ContactName,ContactTitle from( SELECT TOP '+ CAST(@pageSize as varchar(10)) +'CustomerId,CompanyName,ContactName,ContactTitle from( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM( SELECT TOP ' + CAST(@rowsToRetrieve as varchar(10)) +'CustomerID,CompanyName,ContactName,ContactTitle FROM Customers as T1ORDER BY contactname) AS T2 ORDER BY contactname DESC ) AS T3)As T4 ORDER BY contactname ASC'EXEC(@SQLSTRING)RETURNGOWhen I use this. Assume that the Total records returned by the SQLquery is 1198.Thus when I am on Page1 the above Stored Proc (SP) willreturn the first 1000 records.This works absolutely fine.Now I am on Page2, now I need to retrieve only the remaining 198records.But if I use the above SP, it will return the last 1000records.So to tweak this I used the following logic to set the@pagesize variable:Declare @PageCount intselect @PageCount = @TotalRows/@PageSizeif @currentPage @PageCount SET @PageSize = @TotalRows%@PageSizeSince I am on Page2 the above logic will set the PageSize to 198 andnot 1000.But when I use this logic, it takes forever for the SP toreturn the 198 records in a resultset.However if the TotalRows were = 1800, and thus the PageSize=800 orgreater, this SP returns the resultset quickly enough.Thus to get over this problem I had to use the other logic i.e. usingApplication Paging (i.e. first storing the entire result set into aTemp table, then retrieving only the required records for the PAGE)Can anyone suggest what is wrong with my user paging logic?????TIA...

The data I am pulling is correct I just cant figure out how to order by the last 8 numbers that is my NUMBER column. I tried adding FOR XML AUTO to my last line in my query: From AP_DETAIL_REG where AP_BATCH_ID = 1212 and NUMBER is not null order by NUMBER FOR XML AUTO) as Temp(DATA) where DATA is not null
but no change same error.
Output:
1234567890000043321092513 00050020
Select DATA from(
select '12345678'+
left( '0', 10-len(cast ( CONVERT(int,( INV_AMT *100)) as varchar))) +
cast (CONVERT(int,(INV_AMT*100)) as varchar) +
left('0',2-len(CAST (MONTH(DATE) as varchar(2))))+
CAST (MONTH(DATE) as varchar(2)) +
left('0',2-len(CAST (day(CHECK_DATE) as varchar(2)))) +
CAST (day(DATE) as varchar(2))+right(cast
(year(DATE)

I have a fairly complicated data import that needs to be done, but the table structures of the two databases don't match up too neatly. I thought I'd be clever, and create a view in the target database, and import into that view -- only to find out (after reading the manual) that multi-table views are not updatable and cannot be used with BULK INSERT or bcp.
I'm not a database pro, I'm a programmer thrust into this role. Needless to say, I'm a bit of a newbie on these things!
Anyway, the view's code:
<pre>
CREATE VIEW dbo.RJ2_V_Client_Import
AS
SELECT Clients. IDENTITYCOL, Clients.CompanyName,
Clients.Address1, Clients.Address2, Clients.StateID,
Clients.City, Clients.Zip, Clients.CountryID, Clients.PhoneMain,
Clients.PhoneFax, Clients.WebAddress,
Clients.ParentCompany, Clients.DivisionDepartment,
People.NameFirst, People.NameLast,
People.AddressPrimary1, People.AddressPrimary2,
People.CityPrimary, People.StatePrimaryID,
People.ZipPrimary, People.CountryPrimaryID,
People.PhoneWork, People.PhoneWorkExtension,
Clients.EnteredDate, Clients.UserLevelID, Clients.Revenue,
Clients.NumberOfContractors, Clients.SICCode,
Clients.Industry, Clients.ReceptionistName
FROM Clients INNER JOIN
People ON Clients.BillingPersonID = People.PID
</pre>
The reason there is a "People" table is because several (SEVERAL) tables in this database contain records for people, and we felt that this was a better design because of it.
The data we're trying to import contains records for billing contacts, which are the People.* fields referenced. It's extremely important that we get this data in the system.
Since BULK INSERT is out, are there any workarounds? There's got to be some kind of non-manual solution, since I know other people have to do imports that start as one table and end up in two ...
For this particular set, I could do it manually -- only two records are affected. BUT, for future sets, I can't do it manually -- literally thousands of records will be affected, and I just don't have the time (or inclination) to do the entry ... Plus, think of the potential error rate!
Thanks in advance
John

I am trying to update the current row of a cursor that I have declared from Query Analyzer and I keep getting an error message saying the cursor is Read only. This doesn't make sense because BOL says that cursor's are updatable by default. Anyone had this problem?
Ex: This is the statement I am using to update the current row in the cursor:
UPDATE TableName SET Field1 = 'D'
WHERE CURRENT OF CursorName

I have created a view ('Data_test') based on Table1 and Table2 joined in the following manner:
Table1.PrimaryKey <-----> Table2.ForeignKey /* same as Primary Key */
When trying to insert data into the tables through the view, I get the following error:
Server: Msg 4405, Level 16, State 2, Line 1
View 'Data_test' is not updatable because the FROM clause names multiple tables.
Any ideas of how to make the view updatable?

Hi all,
I have a problem with "Updatable Subscriptions" under concurrent transactions on both pub and sub effecting same data. At high level of concurrency it Subscriber starts giving error msg "Rows do not match between Publisher and Subscriber. Run the Distribution Agent to refresh rows at the Subscriber.".Please tell me any way arround for this.

I have been trying to set up replication with updateable subscriptions. I first followed the tutorial on MSDN and set up basic transactional replication. This all worked fine. I then tried, using that tutorial as a basis, to set up replication with updatable subscriptions.
On the Agent Security page you are asked for a Snapshot Agent, a Log Reader Agent and a Queue Reader Agent. I assigned these to the following accounts, which I created and added as logins, PUBLISHERSERVER
epl_snapshot, PUBLISHERSERVER
epl_logreader and PUBLISHERSERVER
epl_queuereader.
I then tried to set up a subscriber on SUBSCRIBERSERVER. Under the publication I add new subscriber, select the publisher, add SUBSCRIBERSERVER as the new SQL server Subscriber. In the Distribution Agent Security page of the wizard it asks for process account, which will be run when synchronizing the subscription. I entered PUBLISHERSERVER
epl_distribution here and selected the other two default options of connecting to the distributor and subscriber by impersonating the process account. I then took the default options for the next few screens and finally get to:
Login for updateable subscriptions. This offers the option of a login or using a linked server. I have tried various logins here, initially trying the €˜sa€™ login and password. This produced the error: The user is not associated with a trusted SQL Server connection. The servers are set up for mixed mode operation. I then tried PUBLISHERSERVER
epl_distribution and subsequently every other account I had created on PUBLISHERSERVER. All of these failed. I tried linking the servers, but this also failed. How exactly do you set up subscriber with the ability to login to the publisher? I have spent days trying to set this up, and am as you can gather new to this technology, any help would be greatly appreciated.

Hello, There are 2 questions that I interested in:Q1: We are planning to scale out SQL Server 2005 with Transactional Replication and use the following topology:NodeA: PublisherNodeB: Publishing Subscriber of NodeANodeC: Subscriber of NodeBIf it is necessary to allow update on NodeC, is it possible to set NodeC as an updatable subscriber? BOL states that Updatable Subscriptions do not support republishing data. But I'm not sure whether it is applicable to these case. Please advice.Q2:In SQL Server 2005 BOL, in claim that "Standard transactional replication assumes read-only Subscribers and is
hierarchical in structure: typically a single Publisher publishes data
to one or more Subscribers. Standard transactional replication also
supports a republishing hierarchy: updates are delivered from a
Publisher to a set of republishing Subscribers, who in turn deliver
updates to a final set of leaf-node Subscribers. Updating
subscriptions offer the ability for Subscribers to push changes back to
the Publisher, but the arrangement is still hierarchical because
changes follow the hierarchical structure when moving between
Subscribers and Publishers. ..." in the topic "Peer-to-Peer Transactional Replication" Could somebody describe how Subscribers push back changes to Publisher in hierarchical structure? Could Republisher setup in the "hierarchical" structure or topology as a middle-node (Not a leaf node nor root node)?Thanks a lot.Terence

Hi all,
I am planning replication around a large SQL Database Server; 3 databases need to be replicated for reporting purposes.
My plan was to use Transaction Replication, as the Reporting database will be mostly read-only. However, we must add a whole bunch of additional, historical data to some of the tables of the reporting database that does not exist in the Publisher. I understand that changes can be made to subscriptions in Transaction Replication scenarios, ideally when the changes are few and far between. (Merge replication is excessive for our purposes.)
I don't want the additional historical data to be propagated back to the publisher. Is it possible that data is written to a subscriber in a Transactional Replication scenario without writing these updates to the Publisher? Given the nature of the data, there will not be conflicts between the historical data and the new changes applied from the publisher.
Any help would be much appreciated!
Thanks,
Faraz

Hi. I receive the SQLException:
[Microsoft][SQLServer 2000 Driver for JDBC]Can not update, the specified column is not writable.
when I attempt to call updateString() on a RecordSet column. I have set the Statement object on which I execute the query to obtain the RecordSet to be scrollable and updatable.
My goal is to replace the ID value contained in a particular column of each row with a longer text string that includes the ID value. If I can't alter the column values via the RecordSet, can I write SQL as part of the query to generate the text string?
Thank you.

Hi All,
I have a problem replicating data from Subscriber to Publisher.
I configured Queued updatable subscriptions in transactional replication. Publisher is on SQL Server Standard edition and Subscriber is on SQL Server Express edition, both on Windows XP.
When I insert/update data in publisher, the data is replicated to subscriber. If I insert/update data on subscriber the data is not replicated. When I see the replication monitor for errors, it shows an error "Cannot load a DLL xprepl.dll or one of its resources".
Could any one give me a solution or please tell me if I missing something?
Thanks you all,
Ravi.
