I am having problem to insert the record into database from sqldatasource control. my code is listed below, and i can't find anything why it cause the exception...
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"
ConnectionString="<%$ ConnectionStrings:WebsiteDataConnection %>"
SelectCommand="SELECT * FROM [ServiceAgents]"
InsertCommand="INSERT INTO ServiceAgents VALUES(@Ser_STATE, @Ser_CITY, @Ser_AGENT, @Ser_PHONE, @Ser_EQUIPMENT)">
And in the code i just called: SqlDataSource1.Insert(); Then the page gives me the exception like:
Cannot insert the value NULL into column 'STATE', table 'WebsiteData.dbo.ServiceAgents'; column does not allow nulls. INSERT fails. The statement has been terminated.
But i actually input all the required text in the textbox.... Any idea guys?
hi i have an sqldatasource which has an insert command - a stored procedue is used.I have a text box with a button next to it . it is not in a datagrid.on the onclick event I would like to pass the value of the text box to the sqldatasource insert parameter ( it only expects this one parameter , and use the sqldatasource to do the insert basically doing a manual insert using the sqldatasource.does anyone know if this is possible thanks
I apologise if i have not posted this in the correct Topic before i start. But was uncertain where to post this query. This is my first project in ASP.NET, MS Visual Web Developer 2005 Express and SQL Server 2005 Express. I have relatively little experience, so please bare with me. I have managed to create a form that inserts data into a table and then inserts the Automatically Created Primary Key(as a foreign key) in another table. I have done this by inserting what is highlighted in red in the code of my InsertCommand below (Please scroll across to the end of the code):-InsertCommand="INSERT INTO [PrinterModel] ([Model], [PrinterMakeID], [CartridgeCode], [PartCode], [Duplex], [NIC], [Wireless], [Parallel], [USB], [Colour], [PrinterTypeID]) VALUES (@Model, @PrinterMakeID, @CartridgeCode, @PartCode, @Duplex, @NIC, @Wireless, @Parallel, @USB, @Colour, @PrinterTypeID) INSERT INTO [Model] ([PrinterModelID],[TypeID]) VALUES (@@IDENTITY, 3)" Can you see any problems that may arise from using this method. This project is an Asset Management System and will be used by no more than a handful of users. My Concern is the use of the @@IDENTITY (As it only stores the last Key used). Should I be using it here? If there is more than one user inserting into tables (Chances of this happening are very low), will the correct Primary key be insert to the table in the above code?Thank you for your comments.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 and SQL 2005 with VB as the code behindi am using INSERT command like this Dim test As New SqlDataSource() test.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString1").ToString() test.InsertCommandType = SqlDataSourceCommandType.Text test.InsertCommand = "INSERT INTO try (roll,name, age, email) VALUES (@roll,@name, @age, @email) " test.InsertParameters.Add("roll", TextBox1.Text) test.InsertParameters.Add("name", TextBox2.Text) test.InsertParameters.Add("age", TextBox3.Text) test.InsertParameters.Add("email", TextBox4.Text) test.Insert() i am using UPDATE command like this Dim test As New SqlDataSource() test.ConnectionString = ConfigurationManager.ConnectionStrings("DatabaseConnectionString").ToString() test.UpdateCommandType = SqlDataSourceCommandType.Text test.UpdateCommand = "UPDATE try SET name = '" + myname + "' , age = '" + myage + "' , email = '" + myemail + "' WHERE roll 123 " test.Update()but i have to use the SELECT command like this which is completely different from INSERT and UPDATE commands Dim tblData As New Data.DataTable() Dim conn As New Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True") Dim Command As New Data.SqlClient.SqlCommand("SELECT * FROM try WHERE age = '100' ", conn) Dim da As New Data.SqlClient.SqlDataAdapter(Command) da.Fill(tblData) conn.Close() TextBox4.Text = tblData.Rows(1).Item("name").ToString() TextBox5.Text = tblData.Rows(1).Item("age").ToString() TextBox6.Text = tblData.Rows(1).Item("email").ToString() for INSERT and UPDATE commands defining the command,commandtype and connectionstring is samebut for the SELECT command it is completely different. why ?can i define the command,commandtype and connectionstring for SELECT command similar to INSERT and UPDATE ?if its possible how to do ?please help me
I am using <asp:SqlDataSource ID and for the Select Command, the following, where the WHERE clause ... for an exact match (=) works correctly: SelectCommand="SELECT [PatientID], [MedRecord] , [Accession], [FirstName], [LastName], [Address1] FROM [ClinicalPatient] WHERE (LastName = @LastName) ORDER BY [LastName]DESC"> I would like to do a "LIKE" search where the LastName Parameter is matched using "LIKE". In this situation how would the syntax be written.... I tried: LastName LIKE '%" & LastName & "%'" But I get an error???? Any suggestions, please... Thanks !!
I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!
i need to dyanamically generate my SQL commands so to do that i am generating sqldatasource commands programmatically rather declaratively. SELECT commands seems to work fine but DELETE isnt doing anything, here is my code:
SqlDataSource sdsConsultant = new SqlDataSource(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { loadDataSet(); //it just loads dataset used by formview initializeSDS(); }
//SELECT sdsConsultant.SelectCommand = "SELECT * FROM Consultants WHERE (id=@id)"; QueryStringParameter id = new QueryStringParameter("id", "id"); sdsConsultant.SelectParameters.Add(id);
//DELETE sdsConsultant.DeleteCommand = "DELETE * FROM Consultants WHERE (id=@id2)"; QueryStringParameter id2 = new QueryStringParameter("id2", "id"); sdsConsultant.DeleteParameters.Add(id2);
hello everybody, i have a question to ask, suppose i have a sqldatasource, can i use it in a method??this is my case, i need to make a new method to count the rows in a datagrid, so i will have to read the sqldatasource. the problem is, how to retrieve it?? usually i use the built in sqldatasource_selected to count the rows.... is there any other way??
My compiler says that the line in bold below is illegal. The error msg I'm getting is: No overload for method 'select' takes '0' arguments. How can I correct this error and execute a SELECT? protected void Button1_Click(object sender, EventArgs e) { SqlDataSource2.Select (); } protected void SqlDataSource2_Selected(object sender, SqlDataSourceStatusEventArgs e) {string strReadyFirstName = e.Command.Parameters["@FirstName"].Value.ToString();string strReadyLastName = e.Command.Parameters["@LastName"].Value.ToString(); } <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT [User_ID], [User_Name], [FirstName], [LastName], [Company_Name], [Department_Name] FROM [CompanyDepartment] WHERE ([User_Name] = @User_Name)" OnSelected="SqlDataSource2_Selected"> <selectparameters> <asp:sessionparameter DefaultValue="TheirUserName" Name="User_Name" SessionField="TheirUserName" Type="String" /> </selectparameters> </asp:SqlDataSource>
I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TESTDrivercommunication %>"
I have an SQLDataSource. The SQL is SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records. e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False What am I doing wrong??? Thanks Craig
I am trying to implement an "advanced search" feature on my ASP.NET 2.0 web form. I have a GridView control and a SqlDataSource. The SqlDataSource control successfully retrieves data when the SelectCommand attribute is set in the aspx page. I need to make it so when a user clicks on a button, it can take a value from a text box and use it in the WHERE clause. I have tried setting the SelectCommand programmatically and then DataBinding but it never accepts the new SelectCommand. What can I do to fix this?
Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select). Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command. How do I get the link button to trigger the update command? Thanks, Mark
Hello, I'm new to the forum and new to SQL, ASP.NET, etc. I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve. I have tried Googling it and came up empty. I have a database in SQL Express 2005 and my website will be accessing several tables within the database. I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set. The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine. The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks
Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!
Is there any way I can use a variable from my code behind file in the UpdateCommand of a sqlDataSource? I have tried <%$ strUserGuid %>and<% strUserGuid %> any help appreciated.Thanks Dave
I have a gridview with a sqlDataSource with the SelectCommand as "SELECT Movie.Title, Movie.Category, Movie.ReleaseDate, ItemForSale.Quantity, ItemForSale.HasUnLimitedQuantity FROM ItemForSale INNER JOIN Movie ON ItemForSale.ID = Movie.ID"
what kinda 'UpdateCommand' do I set so that ItemForSale is also updated from the grid? I tried two update statements seperated with a semicolon but that wouldn't work, any suggestions...
HiI'm using a simple SqlDataSource to connect to a stored proc to delete a number of rows from different tables.In my SQL im using: DECLARE @table1Count int
DELETE FROM Table1 WHERE id = @new_id
SET @table1Count=@@rowcount
SELECT @table1Count I'm then using an input box and linking it to the delete control parameter. Then on a button click event i'm running SqlDataSource1.Delete() which all works fine. But how do i get the @table1Count back into my aspx page? Thanks
Hello all, Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
Hi, Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is: <asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource> This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get) HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query: blogID, title, description, tags, dateAdded, noOfComments 1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0 Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!
On my site users can register using ASP Membership Create user Wizard control. I am also using the wizard control to design a simple question and answer form that logged in users have access to. it has 2 questions including a text box for Q1 and dropdown list for Q2. I have a table in my database called "Players" which has 3 Columns UserId Primary Key of type Unique Identifyer PlayerName Type String PlayerGenre Type Sting
On completing the wizard and clicking the finish button, I want the data to be inserted into the SQl express Players table. I am having problems getting this to work and keep getting exceptions. Be very helpful if somebody could check the code and advise where the problem is??
To match the answers to the user I get the UserId and insert this into the database to.protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e) { SqlDataSource DataSource = (SqlDataSource)Wizard1.FindControl("InsertArtist1"); MembershipUser myUser = Membership.GetUser(this.User.Identity.Name); Guid UserId = (Guid)myUser.ProviderUserKey;String Gender = ((DropDownList)Wizard1.FindControl("PlayerGenre")).SelectedValue; DataSource.InsertParameters.Add("UserId", UserId.ToString());DataSource.InsertParameters.Add("PlayerGenre", Gender.ToString()); DataSource.Insert();
Hi,I am trying to insert data using data from a datalist on the page. To do this, I use the following coding: command.CommandText = "INSERT INTO Messages (sendername,recievername,message,Date,subject) VALUES (@sendername,@recievername,@message,@date,@subject)"; command.Parameters.AddWithValue("@sendername", System.Web.HttpContext.Current.User.Identity.Name); command.Parameters.AddWithValue("@recievername", SqlDataSource2 ); command.Parameters.AddWithValue("@message", TextBox2.Text); command.Parameters.AddWithValue("@subject", TextBox3.Text); command.Parameters.AddWithValue("@date", DateTime.Now.ToString()); command.ExecuteNonQuery(); SqlDataSource is the datasource for the other datalist- will this work?Thanks,Jon
Hi. I'm testing GridView and SqlDataSource controls and I'm using this http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.sqldatasource.insert.aspxI have problems with inserting new items into the db. As I understood from the code in that example, I need to create InsertParamaters and name it just like the one in the insert query. <asp:SqlDataSource ID="Sql1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT * FROM [Clients]" DeleteCommand="DELETE FROM [Clients] WHERE [ID] = @ID" InsertCommand="INSERT INTO [Clients] ([Name]) VALUES (@Name)" UpdateCommand="UPDATE [Clients] SET [Name] = @Name WHERE [ID] = @ID"> <DeleteParameters> <asp:Parameter Name="ID" Type="Int32" /> </DeleteParameters> <InsertParameters> <asp:ControlParameter Name="Name" ControlID="newClientTB" /> </InsertParameters> <UpdateParameters> <asp:Parameter Name="Name" Type="String" /> <asp:Parameter Name="ID" Type="Int32" /> </UpdateParameters> <InsertParameters> <asp:Parameter Name="Name" Type="String" /> </InsertParameters> </asp:SqlDataSource> and I get the following error when run:The variable name '@Name' has already been declared. Variable names must be unique within a query batch or stored procedure. Any help?
Coming from an asp world, I am totally lost on this one. I have two tables. tblUsers and tblUserInfo I have a gridview that gives me the list of users and when selected, it gives me the detailsview of the the record. However, When I need to add a new user, I am trying to add that user into tblUsers (which happens with no problems), and then add a record, using the same user number (UserID) has the key or ID for the tblUserInfo. So basicly, when I create a new user in tblUsers I want to create a record in tblUserInfo with the same userid. In ASP, this takes me minutes... I have been trying to figure this out for weeks. vs2005, sql express. Thanks.
Hello there, I made a page to add these fields (name, description, price, end_date) into a SQL database. I'm using ASP.NET 2.0 with C#, my database is SQL 2005. I did it without DetailsView or FormView, it consists of TextBoxes and a Calendar. Anyways, i wrote this code for Button1, which is the button that adds the data. protected void Button1_Click(object sender, EventArgs e) { SqlDataSource sql = LoginView1.FindControl("SqlDataSource1") as SqlDataSource; sql.Insert(); Response.Redirect("home.aspx"); } The parameters and insert statments and commands are written from the SqlDataSource Insert Query wizard. But I keep getting this error when trying to click Button1. Object must implement IConvertible. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidCastException: Object must implement IConvertible.Source Error:

Hi, I have some problem with inserting data into two separate table which are connected via foreign key like in this example:Students (id_s, name, id_subject)Subjects (id_subject, name)So the point is to add a new student and subject for that chosen student. You have to make two inserts right? but how to pass the primary key to the table with foreign key? The form consists of three texbox: name, name_of_subject. Both id_s and id_subject are increment automatically. Any idea how to do it? I would be very grateful for the working code.Thanks in advance and best regards,N.
Hey forum, the .NET form controls make it extremely easy to manage database data, control + SQLdatasource et voilĂ , its there. i have a web form, and a SQLdatasource with an insert query with parameters (works perfectly, only the Date picker Lite textbox ID as parameter wont register, but i have a thread runnin on their forums for that). when i open the Query builder and execute the query it works! woot! but now, how can i make it execute on a button press? i tried with several commands, like SQLdatasource1.execute, and several other commands i searched (can post later, not behind my test environment with my tools/webpage at the moment). so what is the command to let the SQLdatasource execute it's query? it's all i need to know to make several forms, please ghelp me! :) gr. michael
Hi all, I have few insertions statements in one datasource insert command, which i use for my user creation process adding new billing info shipping info and so on. I've put this code in createuserwizard usercreated step with a try catch code. On the insertion if it doesnt work it deletes the user account. Well lets say the first insertion went trough with out any problems, but the second one got blocked or didnt work length or any wierd on controled issue. I was thinking of putting begin transaction end transaction statements in front and end of the statements but this can prevent the insert not to return error, which will prevent try catch to fire? Basicly the idea is to do all insertions with the user creation, and if one goes down all the others gets reversed. (if possible single sqldatasource, just to make the code look clean)
SqlDataSource UpdateCommand plus Insert I have a SqlDataSource with an UpdateCommand but besides that i need also an Insert command triggered on the same update command. That´s because i need to update a record and at the same time include a log of that update in another database. Thanks
