C# With ADO 2.8: Receiving Current Recordset Does Not Support Updating
Nov 17, 2006
Hi All,
I was using VB6 to access a MS SQL Server database. The code worked and works fine. I then decided to migrate the code to C#.Net 2005 using ADO 2.8 (not ADO.Net). Doing that yields with the same exact code the error message, "Current Recordset does not support updating".
I did a whole bunch of Google searches and didn't see anything useful. Mainly the advice from Microsoft and others is to make sure the mode on the connection string is set to "ReadWrite", as the default is "Read Only" and to make sure to set the lock type to either optimistic or pessimistic. Still others said that the code should set the CursorLocation property of the recordset.
I can safely say that I have been setting the mode to "Read/Write" since the start and have played around with the lock type, cursor location, and open method. Nothing works on C#, BUT VB6 is so totally happy with everything.
The provider works fine, as VB6 works fine, and the lock type is also fine, so therefore the built in suggestions do not apply.
My code is:
// Connection string template. Filled in properly in real code.
strConnect = "Server={0};Database={1};"
// Set the connection properties.
this.SQLConnection.ConnectionString = strConnect;
this.SQLConnection.Provider = "SQLOLEDB";
this.SQLConnection.Mode = adModeReadWrite;
// Open the connection.
this.SQLConnection.Open(strConnect, strUserName, strPassword, -1);
=================
// Create the ADO objects needed.
dbRSAdd = new Recordset();
// Open the recordset.
dbRSAdd.Open(strTable, dbCatalog.ActiveConnection, CursorTypeEnum.adOpenDynamic, LockTypeEnum.adLockOptimistic, (int)CommandTypeEnum.adCmdTable);
// Cycle through each record to add.
dbRS.MoveFirst();
for (lRecord = 0; lRecord < dbRS.RecordCount; lRecord++)
{
// Add a new record.
dbRS.AddNew(System.Reflection.Missing.Value, System.Reflection.Missing.Value);
...
}
// NOTE: The code crashes with the call to 'AddNew'.
I get the following error when trying to delete a recordset from an SQL Server DB:
ADODB.Recordset error '800a0cb3' <o:p></o:p> Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype. <o:p></o:p> /sqlwishlist/Database2_interface/wishlists1/editor/deletionverified.asp, line 33
The code is:
<BASEFONT FACE="Comic Sans MS" COLOR="DarkBlue"> <HTML> <HEAD> <TITLE>WISHLIST RECORD DELETION VERIFICATION</TITLE>
'Use the ADO connection that Access uses Set cn = CurrentProject.AccessConnection
'Create an instance of the ADO Recordset class, and 'set its properties Set rs = New ADODB.Recordset With rs Set .ActiveConnection = cn .Source = RecSourceFloater .LockType = adLockOptimistic .CursorType = adOpenKeyset .CursorLocation = adUseServer .Open End With
'Set the form's Recordset property to the ADO recordset Set WeekDay.Form.Recordset = rs
Set rs = Nothing Set cn = Nothing
End Function
When I edit the form I noticed that I could not go back to a recently added record because it was not available, so I concluded that I had to force an update, which I do in the before update event of my form, as follows;
'Update the underlying recordset Me.Recordset.Update
It works great on my test server here, but when I instal it on the SQL Server 2000 - I get an error 'EOF' or 'BOF' is true......... so it fails
What properties to you set to make a SQL 2005 recordset updatable?In Access, it'sRecordset.editRecordset!FieldName=SomeValueRecordset.updateAny help is appreciated.
I'm updating an ADO recordset inside VB6... We just moved the database from SQL Server 2000 to SS2205....
The following code has worked a long-time now when it tries to update the record with SS2205 on the back-end I get a run-time error '3219' Operation is not allowed in this context...
Here is the Open statement...
SampleRecordset.Open "Select * from samplereleased_view", SampleConnection, adOpenDynamic, adLockOptimistic, adCmdText
I am getting an error (number -2147217887, error message "ODBC--call failed.") when I try to execute an rst.Update. I have an MS Access 2013 application using an ODBC connection to SQL Server 2008 r2. I am using a query to update a table. It is a simple Select query with no joins. I have checked to make sure the table can be updated.
I was not sure if there were any special permissions that I need to set to allow a linked table to be updated in MS Access this way?
updating a recordset contained in an System.Object variable during runtime.
I am trying to execute multiple file actions (plus parsing those files into a set of staging tables) at separate locations in parallel. I know I can do this in C# but I have a business requirement to use SSIS for all ETL operations.
Any one site can have 0 to many of 1 to 3 files. I would like to run multiple sites at the same time, so when all files of all types are completed at that site then go on to the next site in the list. I know I can do a single site at a time in a foreach loop but if I can run lets say 3-5 sites concurrently then I should be able to save execution time.
My thought is to have a recordset of the sites, when any 1 of the 3 (or more) "control flows" is open, update the recordset to let it know that site being actioned, when that site is complete, update the recordset that the site is completed, and so on.Or am I running in the wrong direction?
After I watch a video for how to create MS SQL Replication, I configure distribution and create the publication. The problem comes from subscription. If I create a "PUSH" subscription, it works fine. However, when I create a "PULL" subscription, I got the following error. Where I should look for solution for this error.
I know this is prolly an old one but I would certainly appreciate some assistance =)
environment:
SERVER (IIS6, .NET2.0, SQL2005)
CLIENT (WIN2000,IE6,VBScript)
I have an aspx that is invoking ado on the clientside. I read somewhere that javascript does not support connecting to SQL clientside. I may be wrong. In any case I am using VBScript on the client.
I am using something like this to invoke the script
I posted this in the MS Access group, but no luck.------------------------------------------I've got another stored procedure in the same app that returns multiplerecordsets and the code works.But now I've written another SP and the code traps out with the 3251 message.The SP is writing two recordsets.When I run the SP in Query Analyzer, both recordsets appear.But when I step through the code, when the first RS should be there, it's"Closed" and nothing I've tried will make it open.Provider=SQLOLEDB.1 (which works on the other screen...)Seems like I've been here before, but I can't remember what the problem was.--PeteCresswell
I have a company that sells fruit and vegetables to the catering industry. I take orders in the evening for the next day, and buy my fruit and vegetables from wholesale market to deliver to my customers on the next day. I have sage simply accounting. I have to enter invoices day before I print them, so I can get a list of items i should buy next day (and also sort them into different routes) My question is, is there a way to update all the prices on the active invoices (i.e. not printed or posted) for the previous day, after I enter new prices for the fruit and vegetables??? I need this as at the moment I hava to go into individual invoices and enter the products and quantities again.
Reader Community I've just started hosting my newly created Microsoft Visual Web Developer 2005 Express Edition web site. Unfortunately the Login group membership functions will not function correctly. Having contacted the web service hosting provider, They replied: "We do not support SQL express2005. The only way to use the extra functions of ASP.NET2 such as group membership is if it is using an SQL 2000 database to connect to. " Is it possible to design web sites with Microsoft Visual Web Developer 2005 Express Edition that store membership details on an SQL 2000 database? I've just paid £88 approx. $140 for a years subscription, have I chosen the wrong web service hosting provider? Should I have designed the web site with a better web site design software tool that also makes designing membership login functionality easy, just as Microsoft Visual Web developer 2005 express edition? Look forward to all comments? Regards
I've this query SELECT t1.ID, t1.Date, t1.Time, t1.VALUE FROM RESULT WHERE t1.Date>=CONVERT(VARCHAR(10),DATEADD(d,-7,GETDATE()),101) AND t1.Date<CONVERT(VARCHAR(10), GETDATE(), 101)
Let's say, current date is 8 AUG 2005 and current time is 2045 So, i will get ID | Date (this is datetime) | Time (this is integer) | Value -------------------------------------------------- 204 | 8/1/2005| 2359 | 90 205 | 8/1/2005| 2250 | 99 206 | 8/1/2005| 1950 | 88 ... ... 207 | 8/7/2005| 1845 | 77 208 | 8/7/2005| 2255 | 77 209 | 8/7/2005| 2140 | 77
Can someone can show me to filter data between t1.Date>=CONVERT(VARCHAR(10),DATEADD(d,-7,GETDATE()),101) AND TIME>=CurrentTime t1.Date<CONVERT(VARCHAR(10), GETDATE(), 101) AND TIME<=CurrentTime
If current date is 8 AUG 2005 and current time is 2045, so the result shown as follow
ID | Date (this is datetime) | Time (this is integer) | Value -------------------------------------------------- 204 | 8/1/2005| 2359 | 90 205 | 8/1/2005| 2250 | 99 ... ... 207 | 8/7/2005| 1845 | 77
I only have this query, SELECT t1.ID, t1.Date, t1.Time, t1.VALUE FROM RESULT WHERE t1.Date>=CONVERT(VARCHAR(10),DATEADD(d,-7,GETDATE()),101) AND t1.Date<CONVERT(VARCHAR(10), GETDATE(), 101)
I am writing an SQL stored procedure that returns a dataset as well as a return value. When I execute the stored proc, all seems to work, except the return value comes back as null.
Code:
// Create Instance of Connection and Command Object SqlConnection connection = new SqlConnection(ApplicationConfig.ConnectionString); SqlCommand command = new SqlCommand("SoundLeaf_GetPagedProductsByCategory", connection);
// Mark the Command as a SPROC command.CommandType = CommandType.StoredProcedure;
// Add Parameters to SPROC SqlParameter parameterID = new SqlParameter("@CategoryID", SqlDbType.Int); parameterID.Value = categoryID; command.Parameters.Add(parameterID);
SqlParameter parameterPageIndex = new SqlParameter("@PageIndex", SqlDbType.Int); parameterPageIndex.Value = pageIndex; command.Parameters.Add(parameterPageIndex);
SqlParameter parameterRowCount = new SqlParameter("@RowCount", SqlDbType.Int); parameterRowCount.Value = rowCount; command.Parameters.Add(parameterRowCount);
SqlParameter parameterPageCount = new SqlParameter("@PageCount", SqlDbType.Int); parameterPageCount.Direction = ParameterDirection.Output; command.Parameters.Add(parameterPageCount);
CREATE PROCEDURE GetPagedProductsByCategory] ( @CategoryId int = 0, @PageIndex int = 1, @RowCount int = 10, @PageCount int OUTPUT ) AS Declare @TotalRows int, @StartPosition int
Declare @PK int DECLARE @tmpTable TABLE ( PK int NOT NULL PRIMARY KEY )
DECLARE PagingCursor CURSOR DYNAMIC READ_ONLY FOR select a.ProductId from products a, categoryProducts b where b.categoryid = @CategoryID and b.productid = a.productid Order By a.productid
Open PagingCursor Fetch Relative @StartPosition From PagingCursor Into @PK
while (@RowCount <> 0) And (@@Fetch_Status = 0) begin Insert Into @tmpTable (PK) Values (@PK)
Fetch Next From PagingCursor Into @PK Set @RowCount = @RowCount - 1 end
Close PagingCursor Deallocate PagingCursor
Select Products.* From Products Join @tmpTable temp ON Products.ProductID = temp.PK Order By Products.ProductID
SELECT @PageCount = COUNT(*) / @RowCount FROM Products // value is never returned
I have a scenario whereby I will have 200+ clients putting messages onto a service broker queue. This message will go through a pipes and filters based messaging system, and ultimately the message will pop out the other end.
Here's the question: what is a good way of making sure the same client gets the response to the message he received. Is there anyway I can selectively receive messages from a queue, i.e., pass a correlation id in with the message, and then filter messages based on that id.
Or if someone knows a better way to do it altogether i'd really appreciate it.
Is it possible to receive from a queue by a conversation handle? In the documentation there is an example that show you how to do it. Yet, if you "read" the whole document it says that the conversation handle can not be an expression.
The WHERE clause of the RECEIVE statement may only contain search conditions that use conversation_handle or conversation_group_id. The search condition may not contain any of the other columns in the queue. The conversation_handle or conversation_group_id may not be an expression.
Here is what I'm trying to do:
;RECEIVE TOP(1) @MsgBody = CAST(message_body as XML)
FROM ProcessingLetters
WHERE conversation_handle = @Conversation_Handle
It doesn't seem to matter if I use RECEIVE or SELECT. It will return nothing.
I've even tried this:
where cast(Conversation_Handle as varchar(100)) = cast(@Conversation_Handle as varchar(100))
Why am I doing this? I've put something into the queue to let me know that something is processing. When it is done I want to pull it out and end the conversation.
So is the WHERE conversation_handle = @Conversation_Handle supposed to work?
I am right now looking at the new functionality in SSIS to cover some of the ways we can streamline proceses in the company. I know that SSIS has SendMail tasks, however I was wondering if there is any functionality for going out and receiving mail and parsing those messages in? Would this have to be done as custom code within SSIS and if so can anyone direct me to what would be needed to do so? Thanks.
hi friends, i want to store an image in DB. but most of my friends told that, to store an image in web server then store tat location in a DB and access it anywhere. this is for asp.net in C#-code behind. how to do this? i've a table with a text field. then .......? waiting for ur reply............ note: i need coding. not by using controls. pls...
I created a new column and modified my businesslogic file and the stored procedure. My program uses the SQL helpder class to execute the stored procedure which inserts the article into the database. All of the other previous columns are getting written to, however the new column I created is getting NULL when I open the database to inspect. Why does this happen? I made sure the db column name matches exactly with the params elsewhere.Did I miss something? It's not throwing an error anymore. it's not taking the data I enter into the form and putting it into the db column.
Is there a way for me to set up CDC so that all the processing (SQL Agent, etc) happens on the machine receiving the data? I'd like to move as much of the processing as possible to the destination.
I have just had SQL Server 2005 installed on my machine. I did have SQL Server 2000 on my machine previously and can still access parts of 2000.
In 2005 I do not have the option schema option under security for any of the databases; therefore, I tried creating the schema manually as you will see below.
In 2005 I execute the following
CREATE SCHEMA TEST GO
The message returned is "COMMAND COMPLETED SUCCESSFULLY"
I, then, execute the following
CREATE TABLE TEST.SalesPeople
(
SalesPersonId INT,
SalesPersonName VARCHAR(50)
)
GO
The message returned is
Msg 2760, Level 16, State 1, Line 1
Specified owner name 'TEST' either does not exist or you do not have permission to use it.
Can you give me the correct syntax on how to create the schema manually? Do you know why this is not showing up under security for the databases?
I've done a bit of work with the External Activator but I think it may be a bit overkill for what I need to do (which is RECEIVE messages from a single queue and process them with managed code). I've tried creating a Service Broker Interface service that retrieves messages from this queue, but I notice that if I set the timeout to -1 to watch for messages indefinitely, the Service never completes the OnStart code.
I notice if I change the service's timeout to something greater than 0, the message is retrieved, but this defeats the purpose of using a Windows Service app, which I want to continuously monitor the queue. I noticed the External Activator spawns a thread to start monitoring an EventNotification queue, which I can bypass since I want to monitor the notification's target queue.
Rushi, can you point me in the right direction to create a Windows Service that constantly monitors a queue? Also, I'd like the ability to monitor multiple databases (the queue name would be the same) as well, so if that is not feasible from a Windows Service please let me know.
Also, am I sacrificing scalability by NOT using the External Activator and switching to a Windows Service (I believe the External Activator will spawn multiple instances of the processing executable)?
Can someone post some code that shows a Stored Procedure receiving a cursor that it can process - lets say a group of order detail records are received that must be saved along with the single Order header record.
And, in another example, a SP returns a result set to the calling program. - For example, a particular sale receipt is pulled up on the screen and the order detail is needed.
I have a table that records sales leads and I need to calculate the total number of leads per user and the total amount owed, then then show only the users who have recieved 3 leads. The UserID is an integer.
Here is what i have:
SELECT * FROM ( SELECT DISTINCT UserID, (SELECT COUNT(*) FROM LeadMatches WHERE (UserID = L.UserID)) AS TotalLeads, (SELECT SUM(Price) FROM LeadMatches WHERE (UserID = L.UserID)) AS TotalAmount FROM LeadMatches AS L ) WHERE TotalLeads = 3
This should work but it produced the following result:
UserID | TotalLeads | TotalAmount --------------------------------------------------------------- <Unsupported Data Type> | 3 | 75.00 <Unsupported Data Type> | 2 | 50.00
I have no idea why the result produceing <Unsupported Data Type> for the UserID and have been unable to find a way around as of yet. Any help would be appreciated.
I am doing my first SSB application where two different servers send messages to each other. The logic was all previously tested on a single server between two databases and it worked OK.
The problem I am having is that when the message is received at the target server (I see this in profiler), the stored procedure associated with the queue does not fire.
I see an acknowledgment fire back to the initiator, but it is like the target server does nothing with the initial message.
Any ideas on how I can further troubleshoot this? FWIW, I used the setup tool provided by RemusResanu to set up the routes and service bindings.
While attempting to configure DTC on a Windows xp Pro, SP 2 machine I receive the error message [DTC was installed by the SQL Server. Please reinstall!] Where do I find this installation file to complete the requested task -- any help would be awesome -- I have tried down loading hotfixes, and security updates that mention fixing problems with DTC -- but alas they did not fix my error ;-)
I have an app receiving messages from SQL Service Broker when data is updated. (Messages are located at http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlnotificationinfo.aspx )
When I run this app against a remote SQL Server, I receive the message "Updated" which I expect.
But when I run the same app against the local machine SQL Server, I receive the message "Options".
Does anyone know if there are SQL Server options that must be set to certain values? I can't seem to find anything that troubleshoots this message... either from a SQLServer- or a .NET standpoint.
I am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
I am attempting to Insert multiple rows in a table by passing DataTable to a Stored Proc. My code is the same as the examples on the net, however when I execute the code I receive the Subquery returned more than 1 value error.
I first created up a User-Defined Table Type
My stored proc is as follows:
ALTER PROCEDURE [KCC].[Insert_MaterialJobMtl] @MtlTblMaterialType READONLY AS BEGIN Set NOCOUNT ON;
