Invalid Attempt To Read When No Data Is Present Using SQLdatareader
Jul 2, 2004
I'm trying to determine if the record is NULL/empty or is valid from the datareader.
objReader = strCMD.ExecuteReader
objReader.Read()
if objReader.IsDBNull(0) = true then...
If NULL/Empty, display no records found. If records are found, display "1 or more records have been found". I keep getting the error "Invalid attempt to read when no data is present". I'm not sure what I am doing wrong here.
I'm writing my first .net app in VB.net. I can connect to my database, but get the following error when I try to set a label value. (My code is listed below) What am I missing? Exception Details: System.InvalidOperationException: Invalid attempt to read when no data is present.Source Error:

My query actually returns rows but when I run, I get this error "Invalid attempt to read when no data is present". It says that the datareader does not return any rows. Please help. Thanks in advance Sangita
I have a stored procedure that inserts a record, and then either returns an error or, when successful, returns the entire row. This is a method I use on sites I have developed in other languages when inserting or updating data; I am new to c#.
With C# I have a datareader executing the sp, and the insert works fine, however I get the error "Invalid attempt to read when no data is present." when I try to read the data that should be coming back. I have researched and updated my code so that I no longer get the error, but I still cannot get the data back. I trap the sp in profiler, ran it in anaylzer, and it works fine - data is returned. But in the code, it does not see the data.
I have modified the return results so now I just have the ID coming back and that works fine. But I would rather just return the entire row. Can this be done, and if so, how?
I am getting this error even though there should be data present. When I test the SQL statement in query analyzer, it returns 1 row. <%@ Import Namespace="System.Data.SqlClient" %><%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="Blog" %> <script runat="server">Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Dim strConnection As String = System.Configuration.ConfigurationManager.ConnectionStrings("currentConnection").ToString 'currentConnection is defined in web.config and works when used in other pages on the siteDim dbConn As SqlConnection = New SqlConnection(strConnection) dbConn.Open() Dim strSelectCommandFirstEntry As String = "SELECT MAX(blogEntryId) as maxID FROM site_Blog"Dim cmdFirstEntry As SqlCommand = New SqlCommand(strSelectCommandFirstEntry, dbConn)Dim rdrFirstEntryData As SqlDataReader = cmdFirstEntry.ExecuteReader()Dim strFirstEntryData As Int32 = rdrFirstEntryData(0) 'error occurs here, i have also tried rdrFirstEntryData("maxID") with same errorrdrFirstEntryData.Close()dbConn.Close() </script> When debugging this code and stopping on this line: Dim strFirstEntryData As Int32 = rdrFirstEntryData(0) rdrFirstEntryData has the following values:hasRows = True, FieldCount=1, Item=In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. and when i click the refresh button...Item = Overload resolution failed because no accessible 'Item' accepts this number of arguments. I suspect that the note for "Item" is my clue to the source of the problem, but I don't know what it means. Please, help.
An application I developed normally works great, but it seems that when processing a certian record (and none of the others so far), SQL Server throws this error: "Invalid length parameter passed to the substring function."

The SqlDataReader (orderReader) doesn't blow up or anything until I call .Read() (and, as mentioned, this problem only occurs for one order). What could be happening here?

I was going to post a long message but I found the problem. Yet I do not know how to correct it efficiently.I have a request to my DB using that kind of code : With SQL_Commande valiSqlConnection(True) ' Configure SQL_Commande. .Connection = SQL_Connection .CommandText = "_Fonctions_valiUtilInfo" .CommandType = Data.CommandType.StoredProcedure .Parameters.Clear() Dim SQL_Lecteur As SqlDataReader = SQL_Commande.ExecuteReader If SQL_Lecteur.Read And Not IsDBNull(SQL_Lecteur(0)) Then Return SQL_Lecteur(0) Else Return Nothing valiSqlConnection(False, SQL_Lecteur) End WithMy problem is that I need use a function within the "With" section, and that function calls a request on the DB then closes the query, and when it gets back at executing the remaining part of the code, it stop saying that the query is closed and cannot be excuted anymore. How can I nest a query within an other one without having this problem?
I am getting this exception sporadically in a certain block of code (it usually works): "System.InvalidOperationException: Invalid attempt to MetaData when reader is closed"The code is below:
Since installing Reporting Services on my machine, I have been getting an error whenever I try to execute a reader.read line.
When I ran the same exact code on another machine using someone else's credentials who did not have Reporting Services it ran fine. When I tried to run it on someone else's machine who did not have Reporting Services using my own credentials, I got the same error. Also, when the person who's pc and credentials worked fine on his machine ran the same code back on my machine using his own credentials, he got the same error. When another person who also had Reporting Services tried to run it on his own pc, he got the error as well.
When the reader is first executed (MyDataReader = sSql.ExecuteReader) these were the property values: depth = 0 fieldcount = 5 hasrows = true isclosed = false Item = In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. recordsaffected = -1 (even though there are records) VisibleFieldCount = 5
When the reader is loaded into a table (MyTable.Load(MyDataReader)) then the property values changed to:
Depth = {"Invalid attempt to Depth when reader is closed."} FieldCount = {"Invalid attempt to Depth when reader is closed."} HasRows = {"Invalid attempt to Depth when reader is closed."} IsClosed= True Item = In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. RecordsAffect = -1 VisibleFieldCount = {"Invalid attempt to Depth when reader is closed."}
And when I execute the the following code:
dtReader = MyTable.CreateDataReader()
While (dtReader.Read()) I get this error: "DataTableReader is Invalid for Current DataTable"
Since the code works with someone else's credentials on a machine that does not have SSRS, and the same problem happens for me regardless of what machine I am on as long as I am using my own credentials what could be causing my problem?

OK, I'm using VS2003 and I'm having trouble. The page works perfectly when I created it with WebMatrix but I want to learn more about creating code behind pages and this page doesn't work. I think it has some things to do with Query builder but I can't seem to get change outside "please register". I have the table populated and it is not coming back with "login successful" or "password wrong" when I've entered correct information. Enclosed is what I've done in VS2003. Can you see where my error is? Any help would be greatly appreciated. Thanks again.

How do I tell when there is no more data to read in a SQLDataReader? For example, I have an open datareader that I pass into a function that MIGHT still have a valid row in it when it returns from the function. How do I tell? I can't do a read() because then that current record will go away. I need to be able to tell if there is a current record without doing another read. TIA,
Hello. I have been challanged to build an application that keeps track of inventory and dates of every item that needs inspection on regular intervals. The original application was a .NET windows application and i have been tasked to "port" and improve it to a .NET C# web application. The original database was in access and i have imported everyting to SQL and all the data is in a single table. So far the table is relatively small so i decided to keep the current database design. What i need to do is to select all the items that are comming up for inspection in the comming months and present them. Each item has a uniqe article number (artnr) with the item name, category and location of the item. The location is the part i would like each items to be presented by. Basicly i would like to retrive artnr, name, type and present x number of gridviews or a sorted presentation where each item is shown inside each gw/whatever by location. I also considered moving all locations to it's own table and connect it with a PK/FK to the prinmary article table but i dont know if this will help me or not. Basicly i have no idea how i would present the items by location where each gridview/somethign else is it's own location. I could really use som help with how i can retrive and present the data so it is showed in the above manner.
(Sorry this was posted to VWD2005 Express by mistake) I have created a simple project using ASP.NET 2.0 which enables a user to login. I created the login user using the Web Administration Tool in Visual Studio 2005. I created everything locally and it worked. Locally I have 2 databases. One containing normal data (which my site uses to populate a GridView control) and the other being ASPNETDB.MDF - which contains membership (login user) data. These 2 databases sit in the App_Data folder which is in the root of the project. I have a remote database which is hosted in a shared environment. This is just the one database and it appears to have all tables in the one database (membership tables and normal tables - such as the one I use to populate my GridView control). I uploaded the website and using the Database Publishing Wizard I uploaded the database data to the shared host. I also changed the connection string to point to my remote database. If I visit the website the GridView is populating correctly (pulling data from the remote database) but when I try to login it crashes. The error is "Access denied creating App_Data sub directory". The membership login details for the user I created are in the remote database as I have compared the data in it to the data in my ASPNETDB.MDF local database. If I launch from within Visual Studio 2005 then it allows me to login perfectly well. Please does anybody know why it won't let me login when I access it via the website? Many thanks for any help, Graham
hi can anyone help me out, i have one issue that is how i have to check while adding new user details to database table weather that user name is exist in that table or not. for my application i'm using oracle database and C#.Net. table is g_users and columns are: Name Null? Type ----------------------------------------- -------- ---------------------------- USERID NOT NULL VARCHAR2(5) NAME VARCHAR2(20) EMPID VARCHAR2(5) USERNAME NOT NULL VARCHAR2(30) MOBILE NUMBER(12) EMAILID VARCHAR2(20) DOMAIN NOT NULL VARCHAR2(30) i need to check from c# programming before inserting a new row into table weather username is already exists are not. how to check this one?
Could somebody please help me to stop sending scheduled report when no data is present in the report? Actually I have a daily report which is sent to the client and in a week, two or three days, data will not be there and thus it delivers blank report to the client.
So how can I stop sending blank mails to the client?
I was hoping I could get this to work, so far I can access all the data from the database, but I also want to update it. I placed a button, updateBttn_Click event to update the database.It's not updating though and I am not gettting any errors. Could you please look at the update query in the update button and see if I have it right. Also, I think it might be because I have the first retrieval of the database tables set to ExecuteReader(). Do I need to redo this and use ExecuteNonQuery somewhere else?Thanks in advance. 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;using System.Data.SqlClient;public partial class userpage : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { usrnmeLbl.Text = PreviousPage.CurrentUser; hiddenpassLbl.Text = PreviousPage.CurrentPass; //Define database connection SqlConnection conn = new SqlConnection( "Server=localhost\SqlExpress;Database=MyDB;" + "Integrated Security=True"); //Create command //SqlCommand comm = new SqlCommand("SELECT UserName, Password, UserID FROM UsersTable WHERE UserName = '" + usrnmeLbl.Text + "'", conn); //SqlCommand comm = new SqlCommand("SELECT Father FROM FamHistTable WHERE UserID IN (SELECT UserID, UserName, Password FROM UsersTable WHERE UserName = '" + usrnmeLbl.Text + "')", conn); //SqlCommand comm = new SqlCommand("SELECT FamHistTable.Father FROM FamHistTable INNER JOIN UsersTable ON FamHistTable.UserID = UsersTable.UserID WHERE UsersTable.UserID = '" + usrnmeLbl.Text + "'", conn); SqlCommand comm = new SqlCommand("SELECT * FROM FatherHistTable, MotherHistTable, UsersTable WHERE UsersTable.UserName = '" + usrnmeLbl.Text + "'", conn); //Open connection conn.Open(); //Execute the command SqlDataReader reader = comm.ExecuteReader(); //Read and display the data while (reader.Read()) { string usr = reader["username"].ToString(); usr = usr.TrimEnd(); string pss = reader["password"].ToString(); pss = pss.TrimEnd(); if (usrnmeLbl.Text == usr) { if (hiddenpassLbl.Text == pss) { readDB_Lbl.Text += reader["username"] + "<br />"; //readDB_Lbl.Text += "Your User ID is: " + reader["UserID"] + "<br />"; readDB_Lbl.Text += "Your Father's name is: " + reader["Father"] + "<br />"; readDB_Lbl.Text += "Your Mother's name is: " + reader["Mother"] + "<br />"; } else { readDB_Lbl.Text = "User and Password mismatch."; } } } reader.Close(); conn.Close(); } } protected void updateBttn_Click(object sender, EventArgs e) { SqlCommand comm = new SqlCommand("UPDATE FatherHistTable SET " + "'famUpdteDDL.SelectedItem.Value'" + " = " + "'addPrsnTxtBx.Text'" + "WHERE UserName = " + "'usrnmeLbl.Text'"); }}
I am trying to transfer the data from flat file to sql server.When I am running the package on local server(network server) it works fine.But when I use it to transfer the data to online server it starts and shows 2771 rows transfered and remains on that only, dosent stop or give a error. When i stop the execution I get the following errors:

Was reported to me that reports were running but data was not being displayed. After checknig the Config manager I found that if I went to the reportserver url then clicked on a report it would diplay he correct data. But when trying it on the normal website it would not display anything. Â
Hi there I have a dataset based on a view (the view contains an union all select). In the Data-Tab in BIDS i can execute the query, set all parameters and get the desired results. In the report though, I am getting no values.
My year-parameters are used as row-descriptions and based on that I calculate the year-values in the data region. I don't know what the problem is... should I post the rdl-file?
create table #datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) ); insert into #datatable exec ('select * from datatable where id = 1') select * from #datatable
I still want to retrieve the data and present it in the software's presentation layer but I still want to remove the temp table in order to reduce performance issue etc.
If I paste the code DROP
TABLE #datatable after insert into #datatable exec ('select * from datatable where id = 1')
Does it gonna work to present the data in the presentation layer after removing the temp table?
The goal is to retrieve the data from a stored procedure and present it in the software's presentation layer and I still need to remove the temptable after using it because I will use the SP many time in production phase.
I have a requirement wherein PDF files are being rendered from an .rdl (report definition language), through the use of a SSRS scheduler automatically. The generated PDF file is further emailed to a mailing list, through the same scheduler. However, there are situations where the PDF is generated as an empty file (under certain specified circumstances) [through the automatic scheduler run]. In this situation, it is required not to email the PDF at all. I would appreciate an input which lets me know how to prevent the generation of the PDF file, when there are no records in the dataset that binds to the .rdl.Alternatively, is there any indicator via which the scheduler can be alerted NOT to pick up files 0 KB in size?

Hello Everyone,A have a Managed Stored Procedure ([Microsoft.SqlServer.SqlProcedure]). In it I would like to call a UserDefinedFunction:public static SqlInt32 IsGetSqlInt32Null(SqlDataReader dr, Int32 index) { if(dr.GetSqlValue(index) == null) return SqlInt32.Null; else return dr.GetSqlInt32(index) }I than allways get the following ErrorMessage:Column, parameter, or variable #1: Cannot find data type SqlDatareader.Is it not possibel to pass the SqlDatareader to a SqlFunction, do the reading there and return the result.My original Problem is, that datareader.GetSqlInt32(3) throws an error in case there is Null in the DB. I thought SqlInt32 would allow Null.Would appreciate any kind of help! Thanks

I am attempting to deploy a sample report (SQL 2005 Workgroup w/SP2) and I am receiving the subject error message when I attempt to view the report on the web server. We are using SQL Server 2005 Workgroup Edition connecting to an Oracle database.
Is this a limitiation of this version? In report designer, I am able to select Oracle as a connection type. If I try to create a data source at the server, "Microsoft SQL Server" is the only option available. If I look at the ReportServer config file, I see many other data connection types available. Did I miss a step, or is this a Workgroup Edition limitation (it's not documented as a limitation that I am able to find)?
