Browser Updateable Recordsets ?
Mar 26, 2000
I think it whould be simpler to explain what I am trying to accomplish.
I wish to pull a query to return multiple records from a SQL 7.0 database.
The query is a customers standing order.
I wish to make edits to multiple records then return those records for update.
The HTML pages that I have seen all seem to display tables on a singular record format.
Is it possible to display records in a 'Table' format and allow it to be updated.
Can any one answer this or direct me to a site with the relevent info.
Thanks Stuart

Hello-
I have a view that used to be updateable (except for a few fields, but that is fine). When I use the results of a CASE statement as one of the field values, the entire view is not updateable. The view is pasted below. Does anyone know how to keep my view updateable and, somehow, add this new field? Thank you.

I could have swore I posted this earlier today, but it must not have went through...anyway here goes again.
Is there any way to tell if a view is updateable (updates the underlying table(s))?
Thanks,
Van

I have a view that combines several tables, and lastly one column that is determined by a subquery.
i.e.
CREATE VIEW [View]
AS
SELECT
[TableA].*,
[TableB].*,
(SELECT TOP 1 [Column] FROM [TableC] ORDER BY [Column2])
AS [SpecialColumn]
FROM [TableA] INNER JOIN [TableB]
ON [TableA].[ColumnID] = [TableB].[ColumnID]
I have made INSTEAD OF UPDATE and INSTEAD OF INSERT triggers for this view that will then allow you to modify [View], and it will handle everything, adding/modifying the data in the three [TableX] tables accordingly.
In SQL Management Studio, the following code works fine, and is what is expected...
UPDATE [View] SET [SpecialColumn] = 1 WHERE [ColumnID] = @DesiredID
This will call my instead of trigger and update my special column accordingly exactly how I want it to.
Now, the problem lies in the application layer running on top of the database and how it accesses the view. Any call from the application to update [SpecialColumn] returns an OleDB error stating that [SpecialColumn] can not be modified. I assume that sql server is identifying the column as some sort of a derived column that normally wouldn't be able to be updated, and OleDB is restricting the column to just read only. Is there some way to override that in my view to say that the column is not read-only? Is this an OleDB restriction that can't be handled in the database/view itself?
I've also tried creating a stored procedure that called the exact same
UPDATE [View]
SET [SpecialColumn] = @param2
WHERE [ColumnID] = @param1
and it also works within management studio, but still gives a similar OleDB error about how the stored procedure attempts to update a derived column that can not be modified.
I have a solution where my stored procedure calls the exact same code as the instead of triggers to update the underlying tables of the view manually, however, I'm not asking for a solution like this to my problem, because this works fine, I simply am not happy having to do band-aid workarounds and am wondering if this is a common problem in front-ends and whether it can be handled on the database layer.

I am hoping to create an updatable view from two tables joined on twofields. I have two questions;1. How can I enforce a one to one relation in sql server 2005 based on twofields? Do I need to create one explicitly under relations? Do I cerate anindex on both fields? Is there a step by step process I can look at tocreate one-one relations?2. Is a view updateable if there is a where clause on one of the fields inthe join/relation?Thank again.Regards

How do I make a view non updateable? I want to create a view so that Iwill not be able to update, insert or delete the view so that basetable is not affected (except dropping the view itself). Thanks.

I've been experiencing conflicts in my replication system that I can't seem to get my head around. The following is the scenario:
3 sqlservers, all running sql server 2005. Server B is the publisher and Server A and Server C (64 bit) are subscribers. The Queue Reader Agent runs on the publisher. I set up transactional repl with updateable subscriptions with the default conflict resolution policy of 'Publisher wins'.
There are 2 kinds of processes: 1. Nightly batch updates and 2. Daytime updates by real clients. The Nightly batch updates runs an on the publisher, which is B. Batch updates are massive updates and running it on the publisher makes sense and it works like a charm. Online updates are made on the subscriber 'C'. This subscriber is set to Queued update mode, and everyday I see a significant number of transactions that are detected as conflicts and the Publisher wins. As a result the changes made on Server C are getting lost. I have verified that no user/client is logged into Server B to do any updates. Users complain that their updates are lost. This is the most puzzling and frustrating bit. I don't see how a conflict can happen if nobody is updating data on the Publisher during the day. SQL Updates on Server C are getting rolled back on a conflict detection because the "Publisher wins", and SQL Inserts on server C are getting deleted because they don't exist on the publisher. Now, how can a insert done on the subscriber be marked as a conflict. There is no row on the publisher to compare the unique guid with, how can it be a conflict?
And the Queue Reader Agent crashes every 3-4 days. No useful information except it creates a dump file for which users have no tools to read it.
Has anyone seen this behavior ? Or is there a known bug in the QueueReader Agent?
My users are losing faith in the replication system and so am I.
Thanks for your time,
-chiraj.

Hello,
We have two updateable subscribers and a publisher using transactional replication. The distributor is located on publisher. Currenetly all 3 sites are SQL 2000 SP3. We plan to upgrade all sites to sp4 with minimum downtime (if possible zero). Is it possible to upgrade publisher/distributor first and subscribers after few days?
Thanks,

We have a database set up for transactional replication with an updateable subscription. When we add log shipping to the publication database (sending the logs to a separate server) the publication and subscription entry show up in Management Studio's replication folder on the log ship target server (although the definitions are correct).
Is this configuration legitimate? Can I add log shipping to the subscription database as well?
Thanks... Liston

I am using RMO to synchronize an updateable transactional pull subscription from Sql Express SP2 to Sql Server 2005 64-bit Standard Edition. The data propogates from the server to the client, but changed data on the client does not replicate to the server. Any ideas?
Thanks!

why should one use Recordsets and not SQL itself in database work. Isn't the latter muvch faster, more portable, and needs to be learnt only once?

When I include a field from my SQL Server database, which has it's Allow Nulls value checked, in the data source of any type of control with it's Enable Editing property check, I then can not edit the record! If I remove the Allow Nulls field I can then edit it! What am I missing here?

Replication Type: Transactional With Updateable Subscriptions
SQL Server Version: SQL Server 2005 Enterprise Edition
Publisher, Subscriber1 and Subscriber2 all on same SQL Server
Problem: I am trying to set up a transactional replication with two updateable subscriptions. All three databases are a carbon copy of each other. Every table to be replicated contains an identity key column. I've been asked to create the replication without assigning separate identity ranges for the publisher and the updateable subscriptions. In other words they want a continous ID range. Can this be done without managing identity ranges programatically outside of SQL Server itself?
Example:
Publisher inserts into table test1 in database1. This creates ID 100 for the record. ID 100 replicates to Subscriber1 (database2) and Subscriber2 (database3).
Subscriber1 and 2 identity seeds are then incremented to ID 100. So far, all three databases have the same identity seed in table test1. Subscriber1 inserts into table test1 in database2. This creates ID 101 for the record. ID 101 is replicated to Subscriber2 (database3) and to the publisher (database1).
Subscriber2 identity seed is then incremented to ID 101. However, the Publisher retains it's original identity seed of 100.
Insert into Publisher table test1 will fail since it will try to insert the identity seed of 101 which is taken.
I have tried identity range management Automatic and Manual. Both seem to have some limitations in managing identity seeds unless different identity ranges are assigned for publisher and subscriber.
Can someone recommend a solution to this problem? Can this be done natively in SQL Server 2005 replication. Or can some recommend another approach to make this work?

I have used the Access 2003 Upsize Wizard to create SQLServer Tables, all worked fine except I cannot Update the tables from Access.
The idea being to use Access Forms as the front end to an SQLserver back end as the Access database is quite complex and filled with macros and queries, not one of mine.
I can update the table in SQLServer but the connected tables at the Access end are read only. Why?
Kind regards,
Johnv

Hi,
is there any update on the subject?
Jet has it for ages.
I want to use Scrollable/Updateable Cursors & OLEDB Rowsets opened via Select query.
Last time I have heard that MSFT is planning to add this in the future.
Is there a beta version that I can try?

Hi all,
I've written a query which needs to return different records depending on its argument.
I've used an IF statment to test which of the three SELECT statments should be returned. However, when I try to access the data from VBA in Access I find that the recordset is empty, whereas the query returns thr correct data if I run it in the SQL environment. WHy is this? More importantly, how do I make it return records?
Code:
ALTER PROC [dbo].[spFilteredContractListByUser]
@UserID varchar(7) --The user's 'T' number
AS
PRINT 'User ID is' + @UserID
--Get this user's filter type from tbl
DECLARE @FilterType int
SELECT @FilterType = FilterID
FROM tblFindContractUserFilter
WHERE UserID = @UserID
-- Standard filter
-- Returning all queries matching the username
IF @FilterType = 1
BEGIN
SELECT DISTINCT [Acc No], Business, Type, [Log Date], [Logged By], [Ack. Date], [Ack. By], [Late?]
FROM qryQueriesWorkList
WHERE (suser_sname = @UserID)
END
ELSE IF @FilterType = 2
-- Return only queries acknowledged by @UserID
BEGIN
SELECT DISTINCT q.[Acc No], q.Business, q.Type, q.[Log Date], q.[Logged By], q.[Ack. Date], q.[Ack. By], q.[Late?]
FROM qryQueriesWorkList q
WHERE (q.[Ack. By] = dbo.getEmployeeName(@UserID))
END
ELSE IF @FilterType = 3
-- Return all the queries which have not been acknowledged
BEGIN
SELECT DISTINCT q.[Acc No], q.Business, q.Type, q.[Log Date], q.[Logged By], q.[Ack. Date], q.[Ack. By], q.[Late?]
FROM qryQueriesWorkList q
WHERE (q.[Ack. By] IS NULL)
END
The VBA code is:
Code:
rst.Open ("EXEC spFilteredContractListByUser '" & Me.cmbUserFilter.Value & "'")
Me.cmbUserFilter.Value contains the argument.
Thanks all
Dave

I need to decrease the amount of time it takes to return a set of data of the following format:
State[Provided vai user intput]->All Counties in State->All Cities in County->All Zones in City[usually < 50 or 75 per city]
current behavior:
1. currently user selects state all counties are returned from db
2. foreach county cities are returned
3. foreach city streets are returned
4. objects hydrated with data & display drawn
As you can see this gets expensive. I know there has to be a better way to do this. Any suggestions? We use sql server/c#.net.

Greetings,
I'm having SSIS block right now and thought I'd see if anyone had a simple solution to this.
What I have is SSN data coming in from several different tables, which needs to be inserted into a SurrogateSSN table which just uses an Identity field for the surrogate.
I normally build a seperate package for each detination table, so in each package that has SSN data in the source, I need to insert into the SurrogateSSN table (then I can use the surrogate values later in my package).
What I'm looking for is a simple solution if possible (preferrable using existing non-script tasks, or very short script), where I can pass in the SSN. Is there way to create a package that will accept a recordset (of SSN's) for this insert, that I can call from several different packages, and pass in the recordset of SSN's?
Thanks for your ideas

We have many users with a mobile application running SQL Mobile and using merge replication to get data back to the SQL 2008 R2 database. This has worked very well for many years.
We now have a requirement to have this data reported on using Reporting Services. This is where it gets messy.
Due to a limitation of Report Builder(see this blog) we cannot provide access to users for creating their own reports. The report database is remote from the host and there is no VPN.
We hit upon the idea of creating an almost identical publication but the articles as read-only. It was only after this was done that we started having trouble with our existing mobile users.
It seems that a published article is EITHER Bi-directional OR Read-only even if they are in separate publications.
I then thought of using Transactional Publication but this too is blocked on creation with "automatic identity range support is useful only for publications that allow updating subscribers"(Merge and Transactional publication are mutually exclusive)
So in the final analysis is there a way for me to have merge replication AND some other form of SQL replication/data transfer that can have the same data transmitted readonly to a separate full SQL server database?

Hello,
I have a SP1 that is calling another SP2,
SP2 is using select and returning records
So in SP1 I get 3 different record sets
(as I can see it on Query Analyzer - one after the other)
When I'm trying using the ASP page I get this error:
"Item cannot be found in the collection corresponding to the requested name or ordinal."
How can I access the last recordset ?

Hello Folks,
Using just SQL (within SQL Server 2000), I'm looking to output 2 (or more) recordsets from a one-to-many join between table all on one row. Help! Can someone please show me how to do this if it can be done.

Here's a question you'll never quit hearing: is there a convenient way to page through large recordsets in SQL Server 2000?
I'm writing some software which, for all intents and purposes, works like a messageboard: users can create threads, leave replies, and so on.
I have about a half million records in a few of my tables, and some of my queries return 1000s of results. I'd prefer not to return 1000s of records all at once, so I don't want to page my records in code; I'd rather page them in SQL Server. Naturally, I want to page replies. However, I don't know of a convenient way to page records in SQL Server 2000.

Hey,I've got an Classic ASP app pulling some records out of a DB, whichworked fine when it was Access. When we upped to SQL Server, all of asudden, when the Recordsets came back, all the dates were empty, eventhough the data was showing up in the DB.About a year ago (only code asp apps once and a while), I rememberseeing this and finding something that just had something to do with theorder in which something was being referenced, but I just can't for thelife of me remember what it was.The Dates are set as datetime, length of 8.Anyone know why this happens and a solution?many thanks,rob

Hello all,
I'm writing some stored procedures that first do an Insert or an Update, and then also do a Select to return a Recordset back to an ADO client. However an Insert or Update causes a closed recordset to be produced in ADO. I can skip over the closed recordset with the NextRecordset method.
So the question is, is there any way of stopping the closed recordset being returned? I don't want to have to call the NextRecordset method from ADO as this would mean that the client would need to know about the implementation of the stored procedure.
Has anyone got any ideas on how to get round this?
Thanks

Can anyone help with this problem.
I am doing some mods to an existing db web app in asp. I am providing a facility to copy a subset of related records in a few tables. I am using one recordset to read in the selected records and then copying the data into another recordset creating a new record in the same table. I have to then pick up the @@IDENTITY of the new record so that I can update linked records in other tables.
The @@IDENTITY value returned is null unless I close the selection recordset.
I have created a simplified version of the code to demonstrate this.
The underlying table is called 'test' and it has 2 fields, 'test_id', integer, identity and 'test_desc' varchar(50)
ASP Code
<%
dim objConn, objRS1, objRS2, objRS3
sub OpenDatabase()
'open database object here instead of in page
Set objConn = Server.CreateObject("ADODB.Connection")
'Connect object to database through global.asa application variable
objConn.Open = Application("test_ConnectionString")
'Create recordset object to use
Set objRS1 = Server.CreateObject("ADODB.Recordset")
Set objRS2 = Server.CreateObject("ADODB.Recordset")
end sub
sub CloseDatabase
Set objRS1 = Nothing
Set objRS2 = Nothing
objConn.Close
Set objConn = Nothing
end sub
function UnNull(numval)
if isnull(numval) then
UnNull="NULL"
else
UnNull=cstr(numval)
end if
end function
OpenDatabase
strSQLQuery = "select * from test where test_id in (1,2) order by test_id"
objRS1.Open strSQLQuery, objConn, 1, 3
do while not objRS1.eof
objRS2.Open "test", objConn, 1, 3
objRS2.AddNew
old_test_id = objRS1("test_id")
objRS2("test_desc") = objRS1("test_desc")
objRS2.Update
objRS2.Close
' *1 objRS1.Close
strSQLQuery = "select @@IDENTITY as new_id"
objRS2.Open strSQLQuery, objConn
new_test_id=objRS2("new_id")
objRS2.close
response.write("Old ID = " & UnNull(old_test_id) & ", New ID = " & UnNull(new_test_id))
response.write("<p>")
' *2 response.end
objRS1.movenext
loop
objRS1.close
CloseDatabase
%>
Output
Old ID = 1, New ID = NULL
Old ID = 2, New ID = NULL
If I unrem the lines *1 and *2 then the output is
Old ID = 1, New ID = 11
I realise that there are other ways of doing this but this is only a simplified example whereas the actual application is far more complicated.
Thanks is advance
Kennedy
