Reorder My Rows
May 6, 2005Howdie y'all,
Im adding rows to my database like this:
GroupID = IdentityGroupUser = UserIdGroupColumn = 1 GroupPosition = Count (*) where UserId = UserId AND Column = 1
Int this way my table looks like this on a certain moment:
1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 13 ; 1 ; 1 ; 24 ; 1 ; 1 ; 3
But then i would, for example, like to delete the 3rd row and i like to renumber the last column so form this:1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 14 ; 1 ; 1 ; 3 <- this is my problem
to this:1 ; 1 ; 1 ; 02 ; 1 ; 1 ; 14 ; 1 ; 1 ; 2 <- here it is solved
Whats the simplest sql stored procedure to perform this reordering task???
Thanks,
Wes
SQL With AJAX Reorder List
Apr 6, 2008So far I'm able to populate an ajax control toolkit reorder list with an SQL table, but I can't get it to reorder through the database.The SQL table is something like this-int ListID, varchar Title, int SortingOrder (SortingOrder always goes 1-n, there are no duplicates and no gaps) When the user changes the position of an entry, I need the reorder list to update the SortingOrder of all the pages between the starting and ending place of the reordered entry. I already have that function written, ReorderListEntries (int OldSortingOrder, int NewSortingOrder), but how and where do I call it?Basically, when the user reorders the list, I need it to-1. get the old and new positions of the reordered entry.2. pass this information back to the server3. call ReorderListEntries (old,new)4. partial page refresh the listHelp with this one will be greatly appreciated.

How To Reorder/compact A Column's Values After A Delete?
Feb 27, 2008
The business operation is this:
The data is stored and accessed by Invoice Number and Line Number. If there are 4 lines, 1,2,3,4 and number 2 is deleted the users want lines 3 and 4 reordered to be 2 and 3.
The existing code does things the following way, but I have my suspicions about how bulletproof it is:
Existing Data:
123,1
123,2
123,3
123,4
Begin Transaction
Delete where InvoiceNumber = 123 and LineNumber = 2.
Update set LineNumber=2 where InvoiceNumber=123 and LineNumber=3
Update set LineNumber=3 where InvoiceNumber=123 and LineNumber=4
Commit Transaction
Is there a better way of doing this?
Thanks.

' The Definition Of Object [object Name] Has Changed Since It Was Compiled' Error When Altering A Trigger In 2005
Aug 17, 2007Hello 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!

When Using A Sqldataadapter In VS 2005 I Get The Following Error At Runtime. Object Reference Not Set To An Instance Of An Object
Dec 21, 2006Help! 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?

Predict Query Gives 'DMPluginWrapper; Object Reference Not Set To An Instance Of An Object' Error
Mar 17, 2008
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...

VS 2005 Error 'Object Reference Not Set To An Instance Of An Object' With Integration Services Project Create Failure
May 22, 2008
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,

Reporting Services Error - Object Reference Not Set To An Instance Of An Object
Jan 14, 2008Hello -
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!!!
Script Component Throws Object Reference Not Set To An Instance Of An Object
Dec 27, 2007Hello,
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?
Thanks in advance!
How I Can Use SqlDataReader?
Nov 29, 2007Hi..
Every time I want to read any record from data base I read it in dataset for example:SqlConnection con = new SqlConnection(@"Data Source=localhost ;Initial Catalog=university ;Integrated Security=True");
SqlCommand cmd = new SqlCommand("select [User_AuthorityID] from users where [UserID]='" + TextBox1.Text + "' and [UserPassword]='" + TextBox2.Text + "' ", con);SqlDataAdapter adp = new SqlDataAdapter();
adp.SelectCommand = cmd;DataSet ds = new DataSet();
adp.Fill(ds, "UserID");foreach (DataRow dr in ds.Tables["UserID"].Rows)
{
user_type = dr[0].ToString();
Session.Add("User_AuthorityID", user_type);
.........
Is there easier way to read data from data base?
How I can use SqlDataReader to do that?
Thanks..
SqlDataReader Within Another SqlDataReader - Can It Be Done?
Jun 1, 2008Hey All,
I have come across a situation with two tables, they are dynamic and the user can add and edit values in the tables so I need to build a dynamic display control. It is all based around an FAQ system I have built. The user can create new FAQ categories (that is one table) then create a new FAQ Question & Answer (that is the second table). The tables are linked by the category id. So now I am trying to display the FAQ section like so.
CATEGORY NAME
QuestionAnswerQuestionAnswerCATEGORY NAME
QuestionAnswerQuestionAnswerCATEGORY NAME
QuestionAnswerQuestionAnswer
So my idea was to run a loop within a loop. First loop the category name, then within the category name, loop a second time to grab all of the questions & answers within the category id captured from the first loops sql select statement, then proceed to loop the category name again and of course repeat the process until all loops are completed. However I am getting, and I kinda figured I would get an error about my SQLDataReader. Bellow is my code maybe some type of edit or different recommendation is needed. Any help will do, thanks!Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Using SqlDataReader
Jun 25, 2004i'm using c# and SqlDataReader to simply retrieve data from one column of a database. problem is it's an integer i'm trying to retrieve, and so i'm trying to put it into an int variable, and i get the error "CS0029: Cannot implicitly convert type 'object' to 'int'" . i've looked for an answer for about an hour and every example for the SqlDataReader that i can find deals with strings only or the examples are too complex for me to understand.
there must be an easy way to retrieve this data and put it into an integer! help...
my line of code that creates the error:
int intGuestNum = dtrSelectTotalSessions["online_numSessions"];
Object Reference Not Set To An Instance Of An Object. And Connection String
Feb 18, 2007Hi, 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:

SQL 2012 :: Get Object Type For Synonym Base Object?
Jun 17, 2014I need to get the object type (view, table ...etc) for a synonym base object inside a script. The only place where I see something related to this stored is in column "base_object_name" in sys.synonyms but there I can see only the same with format [database].[user/schema].[name]. After some testing playing with different users without specifying database/schema I think that maybe the object_id must be stored in a another place, my first idea was parent_object_id in sys.synonyms but it isn't stored there.
know if object_id for the base object is stored in any other place ?
Forms Authentication - Object Reference Not Set To An Instance Of An Object
Apr 12, 2007I 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:
ReportingService _rs = new ReportingService();
_rs.LogonUser("myUsername", "myPassword", "");
_rs.Url = "http://myServer/ReportServer/ReportService.asmx";
CatalogItem[] items = _rs.ListChildren("/", true);
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.
Any idea about where to go from here?
