Unable To Make Changes To Disconnected Recordset
May 16, 2007
Its been almost 10 years since I have had to do work with good-old RecordSet objects...
I am filling a RecordSet with data returned from a SQL server via a stored procedure. I then set the ActiveConnection property to Nothing in order to disconnect it so I can make changes to it.
But when I try to set the value on a given row I get back a "Multiple-step operation generated errors. Check each status value" error message. My understanding is that this is indicative of trying to use the wrong datatype. I have verified that the type is correct (I am dealing with integers) so I am at a loss for what the problem could be.
Here is my code:
Set rsPackages = CreateObject("ADODB.RecordSet")
rsPackages.CursorLocation = adUseClient
rsPackages.LockType = adLockBatchOptimistic
rsPackages.Open "EXECUTE stp_FetchPackageData", myConn
rsPackages.ActiveConnection = Nothing
Response.Write("Value: " & rsPackages("TotalCount")) ' returns 0
Response.Write("Data Type : " & rsPackages.Fields("TotalCount").Type) ' returns 3 = adInteger
rsPackages("TotalCount") = 1 ' throws multi-step error
Oddly enough, when I look at the Attribute property of the field I get back a value of 112. When you break it down I think that value indicates the row value is read-only? (Could that be my problem? Just a really bad/unhelpful error message?) But if I try to change it I get back a message saying cannot be done since RecordSet is already open.
Thanks,
Jason

Hi ...
This is a C++ / ADO / SQL question. Maybe not the right forum but I am guessing there are some programmers out there ...
I am trying to use ADO disconnected recordset to insert data into a sql table. I am using AddNew(vField, vValue) with UpdateBatch(). The code below does not throw any exceptions ... but does not add data to the table.
Any comments are appreciated,
Thanks,
Chris

Hello, Code below returns the following error:
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done
<%
Const adLockBatchOptimistic = 4
Const adUseClient = 3
strDataBase = "somedb.mdb"
set cnTraining = server.CreateObject("ADODB.Connection")
cnnstr="Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;Data Source=" & server.mappath(strDataBase) & ";Persist Security Info=False"
cnTraining.Mode = 3
cnTraining.Open cnnstr
set rsSearch = Server.CreateObject("ADODB.Recordset")
rsSearch.CursorLocation = adUseClient
rsSearch.LockType = adLockBatchOptimistic
sSql = "some sql stmt" 'this works fine on its own
rsSearch.Open sSql, cnTraining
set rsSearch.ActiveConnection = nothing
cnTraining.Close
set cnTraining = nothing
%>
My goal is to get a disconnected recordset. The problem here occurs when i try to use the adUseClient value (3) for the CursorLocation. If I don't use a 3 in the CursorLocation it works fine. Hoewever i'm almost certain i have to use the 3 in order to disconnect the recordset. Any ideas? Is my connection string not set up properly to get a disconnected recordset?

I have an update query in an OLE DB Destination (access mode: SQL Command) that updates a table with an INNER JOIN from another table in another database. I'm getting the error, "No disconnected recordset available for the specified SQL statement". Does this have to do with the SQL query trying to access the other database? How can I get around this error?

Good Morning, I've been searching through all the tutorials and questions, have tried many things. I am still getting "[SqlException (0x80131904): An error has occurred while establishing a connection to the server.

I read through the post at http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx but as I'm new to SqlServer I do not know how to check on the first three items.
I'm getting extremely frustrated, and would just like the login portion of this website to start working before my boot ends up through the computer. Please help, lol, thank you.

We're constructing a three-tier application. We want the middle tier to
extract a recordset from the database, disconnect from the database,
then pass the recordset to the front tier. After changes have been made
by the front tier, it will pass the recordset back to the middle tier,
which will reconnect, and update the database.
The problem:
Using stored procedures, the recordset is no longer available
once the connection has been closed. Is there any way, using stored
procedures, to be able to keep the recordset available after the
connection has been closed, either by preserving it, copying it, or
otherwise?

Hello,
I'm having a problem with two mirrored databases, using SQL Server 2005 SP2, that autmatically failed over last night for unknown reasons. I was trying to fail them back over to the primary SQL server because it says the mirror is disconnected and out of sync. Other databases failed over too, but I was able to fail those back over without a problem. It's just these two. I removed the mirror from the secondary server thinking that this would allow me to restore the database back on the primary server, but that didn't help.
These two databases show a status of (Principal, Disconnected / In Recovery) and I still cannot do anything with the two databases on the primary server. When I try to pull up the properties for them, I get the following error:
"Database <Name> is enabled for Database Mirroring, but neither the partner nor the witness server instances are available: the database cannot be opened.(Microsoft SQL Server, Error: 955)"
I cannot delete, detach, Alter or do anything with the databases. If I could just delete them that would be fine so I can just do a restore, but I can't seem to do anything.
Does anyone know what I can do to resolve this problem.
Thanks in advance!
-Jay

I have a .Net database application that we've successfully deployed in a connected environment. Now we have a client that has the need to store data on a central SQL Server and publish that data out to tablet PC's that will be able to disconnect from the central SQL Server. At some point those tablet PC's will come back in and connect to the central server via VPN and will need to push their changes back to the server. Some fundamental questions:
1) Am I correct in assuming that replication is the best way to accomplish this?
If so,
2) Which replication type sounds appropriate to the above scenario?
3) Am I correct in assuming that the tablet PC's will need some version of SQL Server to support editing of the data in the disconnected state?
My perhaps incorrect first take on this was that we could use a licensed SQL Server on the central server and SQL Server Express as a replication subscriber on the tablet PC's.
Any guidance greatly appreciated!

Hi
While a database upgrade schema changes were being made the Mirror became disconnected will this recover itself when it reconnects or will it be the case that we will have to copy the db files to the Mirror and set it up from scratch.
It was set up as a synchronise mirror

Hi All,
I'd like to throw this idea 'out there' to see if I'm missing something I'll later regret.
I'm looking to resolve a scalability issue within our point-of-sale program. Currently the PK on transactional tables (sales and orders) is created by the application layer using a 'MAX(PKCol) + 1' mechanism. Obviously this requires that all users of the system, whether they're local or remote, have current data at any time they wish to insert. It's this limitation I'd like to remove. Most sites are using MS SQL Server 2000. No sites use anything specific to a later version.
By having a PK that can be generated independently of a 'master' database we can overcome this issue. The PK values will need to be unique within a 'group' of shops and able to be generated by a program operating at any level. From 'head office' which manages a number of shops, to the server at a given shop and even the register / till itself should be able to create ID's while disconnected from the server (using a local database).
It seems there's three main ways to accomplish this:
- Identities,
- MachineID, CurrentPK composite.
- GUID's
Identities: I've ruled out identities as I believe the administration overhead of dealing with them makes them impractical (there may be several hundred registers and therefore as many ranges to be set up within a group).
MachineID, CurrentPK composite: The MachineID references a Machine table which has an entry for each ethernet MAC address which connects to the database. The reason I chose to store the MAC in another table rather than simply using it as column is that I'm fetching it from sysprocesses.net_address(nchar(12)) and believe it's computationally cheaper to use an int than a text column. This mechanism means that we can still expose the PK to the user in some cases (eg: InvoiceNumber printed on a receipt). When the local database is not up to date (usually due to network problems) there will be cases where the CurrentPK will be duplicated but kept unique since it's coupled with the new MachineID. The big drawback to this method is that all current code will need to be revised to deal with the composite keys (this will be a significant amount of development).
GUIDs: Ugly to look at and time-consuming to type. They're not something which you'd expose to a user unmodified so realistically this means altering existing code to use a new 'user friendly' number where the PK is currently exposed to them. The use of GUIDs rule-out the use of clustered indecies on tables they're the PK for lest most inserts cause a page split. The splits would also necessitate more frequent index defrags / rebuilds. Using a non-clustered index incurs a penalty Vs a non-fragmented clustered one (doesn't it?) so while this avoids page-splits it comes at a cost.
After all that I think the best solution is to use GUIDs with a non-clustered index for each of the PK's. While it might not be the fastest of the options (slower reads/joins Vs composite PK) it will be significantly faster to develop while maintaining acceptable performance.
Thoughts?

We have mirroring set up on SQL 2005(SP2) on windows server 2003 servers for 6 production servers to DR servers. It is high performance mode(asynchonous). We are using fully qualified server names with default 5022 port. Prod and DR are using same domain service account.
We had network outage for about 30 minutes last weekend and after that network was restored back to normal. Also few SQL 2000 servers have logshipping and it automatically started syncing up after network was restored. However mirroring didn't start automatically. Partners were in disconnected state and endpoints were stopped. For one database, log grew to 40 GB using most of the disk space.
Then we maually had to run
ALTER ENDPOINT Mirroring STATE = STARTED
and then it started syncing up.
Now the question is why it doesn't start syncing up automatically after network is back to normal and recognize the partner?
Is there anyway we can setup timeout or any parameter like that to specify how many times or how long partners try to connect with no luck and then give up?

We're using ADO disconnected recordsets. On SQL 2000, we could update these on the client (without propagating the changes to the server) even if the underlying view or table was non-updatable.
When running our apps against SQL 2005 (using the same client-side environment), we can no longer change any attributes of those disconnected recordsets, that connect to a non-updatable database object (the rest of the app runs fine, we can update all updatable database objects through disconnected recordsets) . Does SQL 2005 respond to such calls differently from SQL 2000, so that ADO recordsets are built in a new way (which makes them read-only in our setting)?
Thanks for any suggestions.

What is the most efficient standalone .NET class that can hold a single disconnected record? The class must also retain column names, but other schema is not relevant (.NET data type is sufficient).If I understand System.Data.Common.DbDataRecord, it provides an interface on a DbDataReader, and has no storage of its own.I'm familiar with DataSet, is that the only .NET-standard class to do this? Thank you,Shannon

I am having trouble setting up my Pull Subscription and I am new to replication.
I have several servers hosting a databased website that will be the same, except for user input and traffic. Quite simply, I need to copy most tables, SPs and data from network to network. I can't use FTP/Web synch ... as I mentioned the networks do not touch eachother or the internet.
On server Web1, it was easy to create a Publication called Pub via the wizard for my database: TheDB. Then on Web1, again, I added a Subscription to the Publication, indicating my second server, Web2, and the same database name: TheDB (I have already backed up and restored TheDB to all my servers). Here's one of the sp's I ran on Web1:
use [TheDB]
exec sp_addsubscription @publication = N'Pub', @subscriber = N'Web2'', @destination_db = N'TheDB', @sync_type = N'Automatic', @subscription_type = N'pull', @update_mode = N'read only'
GO
This is where I feel stuck. Using the wizard on Web2 doesn't allow me to see Web1. So I tried the following on Web2:
use [TheDB]
exec sp_addpullsubscription @publisher = N'Web1', @publication = N'Pub', @publisher_db = N'TheDB', @independent_agent = N'True', @subscription_type = N'pull', @description = N'', @update_mode = N'read only', @immediate_sync = 1
exec sp_addpullsubscription_agent @publisher = N'Web1', @publisher_db = N'TheDB', @publication = N'Pub', @distributor = N'Web1', @distributor_security_mode = 1, @distributor_login = N'', @distributor_password = null, @enabled_for_syncmgr = N'False', @frequency_type = 1, @frequency_interval = 0, @frequency_relative_interval = 0, @frequency_recurrence_factor = 0, @frequency_subday = 0, @frequency_subday_interval = 0, @active_start_time_of_day = 0, @active_end_time_of_day = 0, @active_start_date = 0, @active_end_date = 19950101, @alt_snapshot_folder = N'', @working_directory = N'', @use_ftp = N'True', @job_login = null, @job_password = null, @publication_type = 0
GO
I copied the snapshot folder, ie. 20070709134423, onto CD and moved it into Web2's default replication folder, but I always receive: cannot connect to Distibutor. I've tried using an Alias, as well, but don't understand exactly how I should point that either. I checked the publication's PAL and my Web2 user has rights and is an owner of the Web2 TheDB database.
Any help is appreciated.

I setup an availability Group. (Only 2 servers - Primary And secondary) -- 21 , 22
I also define an listener . IP .. 23
1- In First step I connected To Listener (23) And in a while I inserted A record to a table .
While 1=1
insert into Tbl_T1(f1,f2) Values (1,2)
2- in second, I Stop the primary .
- I expected this while whitout disconnect, continue.
3- The while code stopped whit this message :
Msg 64, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)
4- I execute again the script, And it worked in new primary.
My questions :
1- is the listener disconnected between switched primary and secondary ? OR have we data loss between switching?
2- I did some huge update on Primary that fill the Log fiel space. And in last Update I got this error :
Msg 9002, Level 17, State 2, Line 27
The transaction log for database 'Your_DB' is full due to 'LOG_BACKUP'.
Is this (Fill All space) a reason to switch primary? Or not ?

After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
Thanks,

Hi,
I am trying to cycle through a table and trigger an event based on some critera. I am not sure how to do it. I am a classic VBA guy, so I might be way off:
Dim myConnection As SqlConnection
Dim myCommand As SqlCommand
myConnection = New SqlConnection("MY SQL DATA SOURCE")
myConnection.Open()
myCommand = New SqlCommand("SELECT * FROM history", myConnection)
Dim dr = myCommand.ExecuteReader()
Dim i As Integer = 1
While dr.read()
i = i + 1
' HOW DO I CYCLE THROUGH THE ROWS AND ASK IF A FIELD EQUALS A VALUE
' field name = "Tail"
If dr(i) = ? Then
MsgBox("ok")
End If
End While
dr.Close()
myConnection.Close()

In VB to move a recordset, we used .MoveNext. How about in SQL?
How can I compare two fields in SQL?

hi
I have 3 tables:Article,Source and File.
Each article can have multiple filenames.
The fields of table Article are:ArticleID,SourceID,ArticleDate,ArticleCategory
The fields of table Source are:SourceID,SourceName
the fields of Table File:ID,ArticleID,Filename
Select*from Article inner join Source on Article.SourceID=source.SourceID order by ArticleDate
I obtain a number of recordsets from the above query.
Then for each recordset(Rs1),Let's say for the first recordset
Rs1.MoveFirst
I want to apply this query:
Rs2.Open"Select SourceName,ArticleDate,File.Filename from [RS1] inner Join File on Article.ArticleID=File.ArticleID
I want from the above query to have the Filenames corresponding to each Article because in my VB
form I have 2 command buttons:one gives me the article's definition(Date,Source)
and the other gives me the Filename of the current recordset(Article)
The above SQL syntax is it correct?

Here's my SQL Statement (I'm using MS SQL 2000):
SELECT TOP 2 MenuComments, MenuDate, MenuID, MenuIsActive, MenuName
FROM Menu
ORDER BY MenuDate DESC
This orders the data correctly, but the problem is, I need ONLY the SECOND row, not the top row. Also, because I am sorting for menus entered into the system, I cannot use a variable based on real dates (in other words, I can't use the server clock to help filter the results).
Any and all help would be GREATLY appreciated -- I've been banging my head against this one all day!

Hi,
I am using classic ASP.
Records are grouped together by a GroupUnique number. Some groups are small with about 10 records, othere are larger at about 160.
For each record, I have about 50 columns of data that I need to display on a webpage. Because the 50 columns don't easily fit on the one page, I create two tables, each displaying 26 columns, the first columnn being an ID column. Due to the size of groups, sometimes the tables are very large - and when they get too big it overloads the server.
I think the main problem is the two tables. I use two recordsets (one of them is shown below - although instead of a SELECT * I do in fact name the columns needed for each table). I have to use two because the Recordsets don't like me using the ID column again - once it is used it is gone.
Is there a better way to store all of this information so that I can just use the one recordset? Possibly in an array? Is there a more efficient way of getting the data?
<%
Dim Recordset4__MMColParam1
Recordset4__MMColParam1 = "1"
If (Scramble.Fields.Item("GU").Value <> "") Then
Recordset4__MMColParam1 = Scramble.Fields.Item("GU").Value
End If
%>
<%
Dim Recordset4
Dim Recordset4_numRows
Set Recordset4 = Server.CreateObject("ADODB.Recordset")
Recordset4.ActiveConnection = conn
Recordset4.Source = "SELECT * FROM Table1 WHERE GroupUnique = " + Replace(Recordset4__MMColParam1, "'", "''") + ""
Recordset4.CursorType = 0
Recordset4.CursorLocation = 2
Recordset4.LockType = 1
Recordset4.Open()
Recordset4_numRows = 0
%>
<%
Dim Repeat4__numRows
Dim Repeat4__index
Repeat4__numRows = -1
Repeat4__index = 0
Recordset4_numRows = Recordset4_numRows + Repeat4__numRows
%>

Hi guys,
my first post. So please don't kill me!
I am having some problems. I'm pretty new to sql and really dont know how to achieve more than the basic selects etc.,
My problem is that I have a recordset on one page http://www.photoghetto.com/photo-images/animals.asp that returns the results of all the images in one category. In this case it's animals and wildlife.
The user can click on any image and go to a page that shows a larger detail version of the image. http://www.photoghetto.com/photo-images/animals-photo-detail.asp
What I do is post the ProductID number to this page so that the selected thumb is shown. So for exmaple for the image of the wild cat it is http://www.photoghetto.com/photo-images/animals-photo-detail.asp?ProductID=6
My problem is that on the animals-photo-detail.asp the user has to be able to "scroll" through all the images from the category.
I.e should be able to hit the previous image button and see the stallion image, or the next button to see the butterfly etc., and thus scroll through all the images on this age if he/ she wishes to.
I understand the principles of having a results page and then being able to click on one of the results and getting a detail page. Such as I have it here. With the http://www.photoghetto.com/photo-images/animals.asp as a results page listing all the results of the category, and then when the user clicks on one of the results, goes to a detail page, for example, http://www.photoghetto.com/photo-images/animals-photo-detail.asp?ProductID=6.
My problem is that what I need is the recordset from the listing page to function on the detail page so that the user can scroll through the results in the same order that they were on the results page.
I have searched now for a couple of days online and every tutorial I find shows the same structure. Results Page > Detail Page.
The sql i am using on the detail page is simply,
<%
Dim photos_rs__MMColParam
photos_rs__MMColParam = "1"
If (Request.QueryString("ProductID") <> "") Then
photos_rs__MMColParam = Request.QueryString("ProductID")
End If
%>
<%
Dim photos_rs
Dim photos_rs_numRows
Set photos_rs = Server.CreateObject("ADODB.Recordset")
photos_rs.ActiveConnection = MM_photo_STRING
photos_rs.Source = "SELECT * FROM PHOTOCOLLECTIONS WHERE ProductID = " + Replace(photos_rs__MMColParam, "'", "''") + ""
photos_rs.CursorType = 0
photos_rs.CursorLocation = 2
photos_rs.LockType = 3
photos_rs.Open()
photos_rs_numRows = 0
%>
So I understand why it will only display the one result since thats the detail page.
Is it possible to be able to scroll through the results using the previous and next buttons as I have setup in the display on the http://www.photoghetto.com/photo-images/animals-photo-detail.asp page. For example, http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=6.
Since the resutls are gathered from across the database its not possible to have a href tage that does a <<< http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=(6 -1) or a >>> http://www.photoghetto.com/photo-images/animals-photo-detail.asp=ProductID=(6+1).
I guess it has to be something with a recordset index but does anyone know how to do it? And does anyone have the ability to help me do it?
My boss is kicking my butt now to get this thing online at some point today, and I'm turning to you guys for help if possible.
I'm sorry if this is a stupid question. I've really ran out of ideas.
