Invalid Object Name When Trying To Reference A Database
Mar 19, 2006
Hi There
Let me start by explaining what I am trying to achieve as there may be a better way to perform this. I have two databases and I want to refer to four tables - one in one database and three in the other in a sql select statement.
When I use the query builder in VWD I can only see tables for the database that is defined in the connection string - so therefore how do I add tables from another database? After reading a few posts I realized that all I have to do is use the syntax: database.owner.table (or [database].[owner].[table]). Unfortunately this didn't work and came up with the error "Invalid Object Name".
Assuming that I must have got the owner incorrect I used the Query Tool in SQL Server Express Edition and it worked perfectly! So my sql must be correct, but why will it not work inside VWD?
The two databases are named assessment and aspnetdb - the assessment database contains the table reviews and the aspnetdb database contains the tables TutorDetails, EmployerDetails and StudentDetails.
Here is the connection string and sql:
Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Assessment.mdf;Integrated Security=True;User Instance=True
SELECT Reviews.Programme, aspnetdb.dbo.TutorDetails.Tutor_DisplayName AS [Tutor Name],
aspnetdb.dbo.EmployerDetails.DisplayName AS [Employer Name], aspnetdb.dbo.StudentDetails.Student_DisplayName AS [Student Name]
FROM Reviews INNER JOIN
aspnetdb.dbo.StudentDetails ON Reviews.StudentID = aspnetdb.dbo.StudentDetails.Username INNER JOIN
aspnetdb.dbo.EmployerDetails ON Reviews.EmployerID = aspnetdb.dbo.EmployerDetails.UserName INNER JOIN
aspnetdb.dbo.TutorDetails ON Reviews.TutorID = aspnetdb.dbo.TutorDetails.UserName
WHERE (Reviews.ReviewID = 15)
Disregard the value of '15' in the WHERE statement as this was just put in to ensure I got some valid data back, this will be replaced with a variable eventually.
I know the sql statement works properly, I think the problem may be something to do with either the connection string - any ideas would be much appreciated.
Does any one has any clue for this error ? I did went through a lot of articles on this error but none helped . I am working in Visual studie 2005 and trying to upload image in sql database through a simple form. Here is the code

} } }

When I add a new item to project in VS2005: Project-->Add New Item --> Sql Database I got a error msg "object reference not set to an instance of an object" after click "Add" button. The SQL Server Express is running. How do I fix this problem?
I've got code that on my own machine (visual studio .net 2003 and iis and sql server all exist on this box) works great. I display my test page, which loads a dropdownlist on page_load. This works great on my own machine.
When I move the code to our dev environment. Web server and database servers on separate boxes. I get the error "Object reference not set to an instance of an object" when i try to open the connection to the database. I thought it had to do with permissions and I check all through sql server and everything looks great. I then thought it was the connection string. I still haven't ruled this out, but I wrote a quick vbscript app to attach to the database and try to pull a record. The vbscript worked fine. So, the code works fine on my computer, but not on the web server. The connection does work with vbscript, but through my asp.net web app I get the "object reference" error.
All code below...
ASP.NET webpage: private void Page_Load(object sender, System.EventArgs e) {
if( !IsPostBack ) { // Create a command object for the query string mySelectQuery = "select id from vw_abcd order by ID";
SqlCommand myCommand = new SqlCommand(mySelectQuery,sqlConnection1); sqlConnection1.Open();

I am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.

is there something which i did not install or what can be the error?
Hi all,I'm a complete newbie on ASP.Net.I want to get some data out of a SQLserver Database running on my system with SQL Server 2005 Express.

I setup the copy db as a schedule but it keeps failing which invalid object name which i think would suggest that the import table is not there?? even thought it is there I have checked the structure of the table which looks fine.
Does anyone have any ideas to get around this?? Or can I do some other checks?

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.

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.

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.
I am trying to execute this code feom Script task while excuting its giving me error that "Object reference not set to an instance of an object." The assemblies Iam referening in this code are there in GAC. Any idea abt this.
Thanks,
Public Sub Main()
Dim remoteUri As String
Dim fireAgain As Boolean
Dim uriVarName As String
Dim fileVarName As String
Dim httpConnection As Microsoft.SqlServer.Dts.Runtime.HttpClientConnection
Dim emptyBytes(0) As Byte
Dim SessionID As String
Dim CusAuth As CustomAuth
Try
' Determine the correct variables to read for URI and filename
uriVarName = "vsReportUri"
fileVarName = "vsReportDownloadFilename"
' create SessionID for use with HD Custom authentication
CusAuth = New CustomAuth(ASCIIEncoding.ASCII.GetBytes(Dts.Variables("in_vsBatchKey").Value.ToString()))
I'm getting this problem 'Object reference not set to an instance of an object.' whenever I try to review a report and I checked the log file and this is what it had

Some previous forums stated checking the webconfig file but the web config file look okay. Is there another way to fix this.
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?
I've ran into trouble while creating a rather simple transformation script component (one input, one output). The only thing it has to do is test the values coming from it's input rows and set the values of the output rows according to some rules; something like:
Code Block
Public Overrides Sub InputBrowser_ProcessInputRow(ByVal Row As InputBrowserBuffer)
If Row.UserAgent.Contains("MSIE") Then 'test input Row.BrowserName = "Internet Explorer" 'set output End If
End Sub
This raises an "Object reference not set to an instance of an object." exception. Commenting out the input (Row.UserAgent) solves the exception, but I actually do need to test the contents of the input row (and by leaving only the output manipulation, the script won't reach it's end, the components remain yellow). What can I do about this?
Hi, I am deploying my web through a web hosting services which provides SQL database support. I got following errors whenever I try to open my webpage,which never happen when I run my web on the local machine. I have my connection string configured in my web.config as below: <add name="ArtHouseConnection" connectionString="Server=serveripaddress; Integrated Security=True; Database=arteh3_database;User Id=username;Password=password;" providerName="System.Data.SqlClient"/> <add name="ASPNETDBConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/> This is the source code where error was generated: public static class ArtHouseConfiguration { //cache connection string private readonly static string dbConnectionString; //cache data provider name private readonly static string dbProviderName; private readonly static string siteName; //initialize constructor properties static ArtHouseConfiguration() { dbConnectionString = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ConnectionString; dbProviderName = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ProviderName; siteName = ConfigurationManager.AppSettings["SiteName"]; } and finally this is the error mg I got: Object reference not set to an instance of an object.

I have successfully implemented forms authentication, that means, I can access it from a web browser, get the login page, add my credentials and log on to Reporting Services.
But now I try to access reporting services Web service from a winforms app, doing something like this:
The first three lines works fine, but he last line (ListChildren) throws a "Object reference not set to an instance of an object" exception. I have enabled remote error and looked in the RS log files, but nowhere I can find where this null-pointer exception occured.
When I try and parse a simple execute of a stored procedure in the Execute SQL Task Editor, I get the error:
"Object reference not set to an instance of an object"
Now, I ONLY get this error on my laptop, so I'm assuming it might be an installation error. I've tried to do the exact same thing in other environments, and received no error. Here's what I'm doing:
1. I create a simple stored procedure on a SQL 2005 database. Here's what it does:
create proc usp_testsp
as
begin
select 'whatever' ;
end
2. I create a new SSIS package in BIS.
3. I create an ADO.NET connection to the above SQL 2005 database
4. I pull over an Execute SQL Task item from the toolbox to the Control Flow tab.
5. I choose the ADO.NET connectiontype, the connection I created in #2, SQLSourceType of Direct input, SQLStatement is: exec usp_testsp, IsQueryStoredProcedure set to True. And I try ResultSet as both Single row and None
When I try to Parse the Query, I get the above error. If I still try to run the task in the debugger, here's what I get with the ResultSet set to None:
Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "exec usp_testsp" failed with the following error: "Could not find stored procedure 'exec usp_testsp'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
And just so you know, I can execute the sp with no problems. And just to check, I granted execute to public on the sp.
And here's what I get with ResultSet set to Single row:
Error: 0xC00291E2 at Execute SQL Task, Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_SingleRow".
I only get this on my laptop. I have SQL Server 2005 SP2 Developer Edition on Windows XP Professional, SP2.
Does anyone see the error below before? I am using SSIS Execute SQL Task (ADO.NET) to update a table using a stored procedure. It works like this many times for me and all of a sudden, not sure what is changing in the environment, I kept getting this WARNING when I click on PARSE QUERY €śObject Reference Not Set to An Instance of an Object€? when I click on PARSE QUERY.
This is going against SQL SERVER 2005 SP2 x64 Enterprise.
Note that this task executes fine and the stored procedure updates data.
The stored procedure does the following. There are other stored procedures of different kinds and they all worked. But all of them give this error when I click on PARSE QUERY.

In visual studio 2005, I create a new Integration Services Project. It tries to create the first package by default "Package.dtsx". The "Package.dtsx[Design]" tab displays
Microsoft Visual Studio is unable to load this document
Object reference not set to an instance of an object
I try to create new SSIS package or edit an existing one (from tutorial), I get the same error in the SSIS graphical user interface tab.
I have a script task that worked FINE yesterday. Now when I run it, I get the following error:
[myTask [64]] Error: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper90 wrapper, Int32 inputID, IDTSBuffer90 pDTSBuffer, IntPtr bufferWirePacket)
Yesterday, literally I was banging my head to the wall, kept getting this error:
A Connection could not be established with the information provided. Hit OK to change your connection settings. Invalid object name 'sysdatabases'.
I uninstall and re-install back the reporting services couple times and I kept getting the same error. I have 2 instances of SQL Server on the same Server:
SQL Server 2000
SQL Server 2005 The 2 instances work side by side, I was wondering if this causing the error.
....not to me, anyway. And I have searched. I'm getting this in several places, and I'm sure there's something underlying the I just haven't cottoned on to yet. Please have a look at the following. The error appears in the "SqlTextSource.SelectCommand=" line. Debug shows SqlTextSource is null, but why? It's in the .aspx! Thanks very much. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="AddText.aspx.cs" Inherits="AddText" MasterPageFile="Admin.master" %> <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> <div> <asp:SqlDataSource ID="SqlTextSource" runat="server" ConnectionString= etc etc SelectCommand= DeleteCommand= InsertCommand= etc etc <DeleteParameters> <InsertParameters> etc etc </asp:SqlDataSource> </div></asp:Content> using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls; public partial class AddText : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { SqlTextSource.SelectCommand = "SELECT * FROM [text]"; }}
When I operate like this: "Select APP_DATA node -> Add New Item -> Sql Database ->create a new aspnet.mdf file .However ,I get a error dialogbox like this :: object reference not set to an instance of object .Can someone who know how to solve this problem help me ?Thanks a lot !
