What Does Object Was Open Error Mean?
Feb 14, 2005
Hi, I am accessing an MSDE Database from within a C# program. When calling the OleDbConnection.Open() method, I get the following error:
Exception: System.Data.OleDb.OleDbException
Message: Object was open.
at System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr)
at System.Data.OleDb.OleDbConnection.InitializeProvider()
at System.Data.OleDb.OleDbConnection.Open()
Now I do not know what this means, since the Connection isn't open. And I do not know why this occurs. I am accessing the same database (but other tables) in the same program several times in the same way and do not get this error.
Any ideas?

I Can't reproduce the error if I run the package stand-alone.
I'm using the same lookup call (same table, etc.) in 2 packages that are running in parallel (called by a parent package).
[LKP_UnderwriterId [72283]] Error: An OLE DB error has occurred. Error code: 0x80040E05. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80040E05 Description: "Object was open.".
Anyone seen this one?

When I open up my existing SSIS project, I always get this error. Does anyone know what was wrong ?
TITLE: Microsoft Visual Studio
------------------------------
Unable to cast COM object of type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.PackageNeutralClass' to interface type 'Microsoft.SqlServer.Dts.Runtime.IObjectWithSite'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{FC4801A3-2BA9-11CF-A229-00AA003D7352}' failed due to the following error: The application called an interface that was marshalled for a different thread.

I am getting an error 'Object was open' when executing a stored procedure with larger am amounts of data. This procedure runs from a VB 6.00 application on SQL 2005. When running the script in SQL there is no problem
rs.Open cmd, Options:=adCmdStoredProc
IMPORTANT: This error ONLY happens with large amount of data. The threshold level is about 250000 rows of data. If more than that amount of data is retreived the error occurs. If less then there is no problem.
Any suggestion would be greatfull
Thanks

Hello group!I use MS Visual C++ 6.0, ADO, MS SQL Server 2000.When I attempt to open my database I meet with a following problem:when I try to get a bookmark of the current record in a Recordsetobject a following run-time error occurs: Unhandled exception intestdb.exe(KERNEL32.DLL):0xE06D7363: Microsoft C++ Exception.I created my database by 3 SQL commands:create database testdbcreate table testtable(i int)insert into testtable values(0)The error occurs in the following code snippet:#import "D:Program FilesCommon FilesSystemADOmsado15.dll" no_namespace rename("EOF", "EndOfFile")int main(){CoInitialize(NULL);bstr_t strCnn("Provider=sqloledb;Data Source=;""Initial Catalog=testdb;Trusted_Connection=YES;");const char* tablename = "testtable";_RecordsetPtr recs;recs.CreateInstance(__uuidof(Recordset) );recs -> Open(tablename, strCnn, adOpenStatic,adLockOptimistic,adCmdTable);_variant_t bm = recs -> Bookmark; // the error occurs hererecs -> Close();CoUninitialize();}During the debugging this code I met that the error depended on a typeof locking.

By the way this error doesn'toccur whenI open Pubs database with any type of locking. What is a cause of thiserror?Thank you.

Hello All
Not sure if this is the right forum to post this question to, so if it's not, please accept my apologies.
I'm working in SQL Server 2005 with a database that was migrated to 2005 from SQL Server 2000. I have to alter a trigger on a table for some functionality changes, and when I modify the trigger and then access it through the application the database is working with, I receive this error:
There was a error in the [stored procedure name] procedure. Error Number: -2147217900 Error Description: [Microsoft][ODBC SQL Server Driver][SQL Server]The definition of object '[trigger name]' has changed since it was compiled.
[stored procedure name] and [trigger name] are where the actual names appear in the message.
I've tried running sp_recompile on the trigger, stored procedure, and table that are associated with this, and nothing works. I have dropped the trigger, which allows the save process to complete (but doesn't perform the required functionality, of course), and then re-created the trigger, but the error message still comes up. The compatibility level for the database is SQL Server 2000 (80) (as it was migrated from SQL Server 2000 as I mentioned above).
Has anyone seen this, and if so, how can I fix it?
Thanks in advance for your help!

Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below. I have dropped a sqlconnection, sqldataadapter and a strongly-typed dataset from the toolbox onto the component designer for my page and written my code. It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object." The error occurs at the first line where the sqldataadapter is mentioned. I have shufflled the code and the error still occurs at first mention of the dataadapter. I have set parameters to a simple string such as "myemail." It hasn't helped. I have used the "Dim" statement as "Dim DaAuthorLogin as System.Data.SqlClient.SqlDataadapter and Dim DaAuthorLogin as New ......) at the start of the private sub generated by the event requiring the data. Nothing helps. Here is my simple code to select data from a sqlserver 2000 database. Why do I continue to get this error?

Hi,
I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:
Executing the query ...
Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader
COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object..
Execution complete
I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file)
So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.
As I said it is not a very descriptive message but I hope I have hit a general issue.
Thanks...

Just installed VS 2005 & SQLServer 2005 clients on my workstation. When trying to create a new Integration Services Project and start work in the designer receive the MICROSOFT VISUAL STUDIO 'Object reference not set to an instance of an object.' dialog box with message "Creating project 'Integration Services project1'...project creation failed."
Previously I had SQLServer 2000 client with the little VS tool that came with it installed. Uninstalled these prior to installing the 2005 tools (VS and SQLServer).
I'm not finding any information on corrective action for this error.
Any one have this problem and found the solution?
Thanks,

Hello -
For the life of me I cannot figure out why i'm getting the "Object Refence Not Set To an Instance of An Object" error after I try and create a Report Services project in Business Intelligence Studio. I've followed all of the steps in similar posts such as checking the ReportServer/web.config file but everything checks out.
Does anyone have any other ideas as to how I can get rid of this annoying error and start creating some reports?
Thanks!!!

There are certain errors that does not come during compilation and it shows during execution because of late-binding concept implemented in SQL Server from 7.0 version.
The problem is when Tables are not there, SPs are created. And there is no option where we can set like 'Validate object resolution during compilation"
There are lot of SPs that are in invalid status because the tables are really not there and SP needs to be modified to reflect the correct table name. In Oracle, if I have to find the list of objects that are in invalid state (because of object resolution problems), it was possible. How do I do it in SQL?
I need a listing of all objects in my database that is in invalid state. Searched in NET but there seems to be no supporting tool also that lists invalid objects.
Pl let me know whether there exists a way by which I can get to know the invalid object lists in my SQL 2005 database

Looking at the below code you can see that I have a separate Connection for each Insert Statement.'OPEN CONNECTION TO ESOSQL
MyConnection = New SqlConnection("......")
MyConnection.Open()

MyCheck.CommandType = CommandType.Text
MyDataReader = MyCheck.ExecuteReader
If MyDataReader.HasRows Then
MyConnection1 = New SqlConnection("...")
MyConnection1.Open()
MyInsert = New SqlCommand("INSERT INTO ARREST_INDEX (ARRESTNO, NOTES) VALUES ('" & Session("uid") & "','" & tx_notes.Text & "')", MyConnection1)

MyConnection2.Close()

Else
div1.Style.Add("display", "block")

I am developing a web service that uses a sql data connection.
The sql database is on a server, and the development version of my web service is on my pc.
I can connect/access the data accross my network when I run the service on my PC, but as soon as I put the web service onto the server(with the sql) it displays, the service wont function - error: 40 - could not open a connection....
I presume that sql is configured correctly as I am recieving data back when I request it accross the network. I dont understand why it wont work when I have the service on the server with the sql?
Any help will be appreciated.

Hello everyone:
I am developing a PDA application, everything is fine for me, but when I try to open Sdf DataBase (was generated by the Wizard ADS ), it gives me the following error pda:
Unable to load a DLL SQl Server Compact. Reinstall SQL Server Compact. [DLL name = sqlcese35.sys.dll]
I commented that i reset the hardware pda several times and I have reinstalled these files:
sqlce.dev.ES.wce5.armv4i.CAB
sqlce.repl.wce5.armv4i.CAB
sqlce.wce5.armv4i.CAB
They are located at:
C:Program FilesMicrosoft SQL Server Compact Editionv3.5Deviceswce500armv4i
They say that my PDA have Windows Mobile 6.0, i development in Visual Studio 2005 C#, and the processor is a Marvell in uan IPAQ 114 Classic, my doubts are several:
-- Is this the whole package for this processor?
-- How to i konw that the package it is up to each type of processor?
-- If this package ... What should I do to correct the mistake?
Best regards and thanks in advance.

Hi there,
I have written a program that loads a package (SomePackage.dtsx) from the physical drive and executes that. The package does nothing but imports data from a csv file to the Sql server 2005. But I can see that the package is failing continuously. I meant the package.Execute() method is returning a DTSExecResult.Failure. I investigated the Package.Errors property that contains the error collection and found that there are two DTSError objects into the collection.
The first one€™s description says that
Cannot open the datafile "D:SOME.csv".
And the later one€™s is
component "SOURCE FLAT FILE COMPONENT" (1) failed the pre-execute phase and returned error code 0xC020200E.
But the most interesting thing is if I execute the package through the Execute package Utility (double clicking onto the SomePackage.dtsx file) ships with Sql server 2005 then it executes fine and works as expected. I have checked the permission of the csv file and it has everyone€™s full access.
Can anyone help me on this?
I will appreciate all kind of suggestions.
Thanks
Moim

TITLE: Connect to Server

ADDITIONAL INFORMATION:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

So, Please help me to solve this problem.
