I have a table (Table1) with an autoincrement column (sql server 2005) and in my asp .net code (c#) the user can delete a row (record) in gridview (by clicking on delete link).
The problem is that every time if the user adds a new record in gridview the new row has a wrong number.
What I mean is:
Table1 has two columns: ID and Category
ID Category
1 test1
2 test2
3 test3 -> delete this row
Now insert a new row:
ID Category
1 test1
2 test2
4 test3 -> ID is 4, but it should be 3
This is killing me. I've searched the forums for hours and can't find the answer. My SQLDataSource is working fine except when I want to delete. I've allowed the delete function to be shown on the gridview. This is my SQLDataSource: <asp:SqlDataSource ID="IndexDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:IndexConnectionString %>" SelectCommand="SELECT * FROM [Index] WHERE (Type LIKE '%' + @SearchText2 + '%') OR (Product LIKE '%' + @SearchText2 + '%') OR (Version LIKE '%' + @SearchText2 + '%') OR (Binder LIKE '%' + @SearchText2 + '%') OR (Language LIKE '%' + @SearchText2 + '%') OR (CDName LIKE '%' + @SearchText2 + '%') OR (Details LIKE '%' + @SearchText2 + '%') OR (ISOLink LIKE '%' + @SearchText2 + '%')" DeleteCommand="DELETE FROM [Index] WHERE [ID] = @original_ID" UpdateCommand="UPDATE [Index] SET Type = @Type, Product = @Product , Version = @Version, Binder = @Binder, Language = @Language, CDName = @CDName, Details = @Details, ISOLink = @ISOLink WHERE ID = @ID"> <SelectParameters> <asp:ControlParameter Name="SearchText2" Type="String" ControlID="SearchText2" PropertyName="Text" ConvertEmptyStringToNull="False" /> </SelectParameters> <DeleteParameters> <asp:Parameter Name="original_ID" Type="Int32" /> </DeleteParameters> <UpdateParameters> <asp:Parameter Name="Type" /> <asp:Parameter Name="Product" /> <asp:Parameter Name="Version" /> <asp:Parameter Name="Binder" /> <asp:Parameter Name="Language" /> <asp:Parameter Name="CDName" /> <asp:Parameter Name="Details" /> <asp:Parameter Name="ISOLink" /> </UpdateParameters>
</asp:SqlDataSource> It doesn't give me an error if I click delete but it doesn't delete the record. I've tried changing the DeleteParameter to <asp:Parameter Name="ID" Type="Int32" /> but it gives me the error "Must declare the scaler variable of '@ID'"... I saw in this post http://forums.asp.net/p/1077738/1587043.aspx#1587043 that the answer was that "The variable you have declared in the definition of the proc is different from the variable you are using in the WHERE clause." when they are both the same. Thanks for any help.-Brandan
I've got an issue that when I update a record in the gridview it works fine. When I click the delete link to remove the record from the database, I get the following error, "System.FormatException: Input string was not in a correct format". Part of the Stack Trace refers to "String oldValuesParameterFormatString". This parameter is in my SqlDataSource. It was dynamically created when I originally created the SqlDataSource with VWD 2005 Express Edition. The delete function will work if I remove "OldValuesParameterFormatString="original_{0}" ProviderName="System.Data.SqlClient", and any reference to "original_" in the DeleteCommand the SqlDataSource. But if I do, the update function doesn't work. Anyway, here's the SqlDataSource: Any help would be greatly appreciated!!!!!

Hi all,Happy New Year!I've just install VS .NET 2005 and try to play with Gridviewwhen I configure the datasource for Gridview and click "Advance" in order to enable Update, Delete Select etc...the checkBox is not selectableCan someone pls show me how?Thanks in advance.
Hi guys! I have a simple windows form where a gridview is being populated by a database. I have checked the ability to update, insert delete. And everything is fine but when i want to delete a row it throws an exeption. The exeptions says: "Must declare the scalar variable "@id"."I haven't changed the delete, update and insert commands. They are as fallowsDeleteCommand="DELETE FROM [recepti] WHERE [id] = @id"InsertCommand="INSERT INTO [recepti] ([ime], [recepta], [snimka], [snimka2], [tip]) VALUES (@ime, @recepta, @snimka, @snimka2, @tip)" SelectCommand="SELECT * FROM [recepti]"UpdateCommand="UPDATE [recepti] SET [ime] = @ime, [recepta] = @recepta, [snimka] = @snimka, [snimka2] = @snimka2, [tip] = @tip WHERE [id] = @id" The id column is auto generated, unique, also it's a primery key.So any idea where is the problem?
The function that is supposed to delete a row, is not working. The function is called, and the windows is refreshed, but the row is not deleted.Can anyone see anything wrong with this code:public static void DeleteBlog(int original_BlogID) { string insertCommand = "DELETE FROM Blog WHERE BlogID = @BlogID"; SqlConnection myConnection = new SqlConnection(Blog.ConnectionString); SqlCommand command = new SqlCommand(insertCommand, myConnection); command.Parameters.Add(new SqlParameter("@BlogID", original_BlogID)); myConnection.Open(); command.ExecuteNonQuery(); myConnection.Close();}
I've not been able to test this yet in full VS2005 (MS is screwed up with orders for some reason. Has anyone heard this one. All orders for less than quantity=5 were being rejected). So, instead of waiting for it I installed VWD Express. Now, the project had been built in VWD express beta 2, so no big change there.Several gridview controls in the project had <Delete> enabled. Just <Delete> mind you. Nothing else for command buttons. They all worked fine with delete queries that use gridview.selectedvalue as the parameter. Every single one stopped working since I've converted from beta 2 to RTM!Here's what I determined. The delete will only work if the row in the grid is selected first!. Otherwise <selectedvalue> is null when you click on <Delete>.Is this a bug or what?I'd be happy to supply more details. I am certain others will report this, but I have yet to find a post here or in any blogs out there that reproduce this problem in the RTM of .NET 2.0
I have a SQLDataSource that gets it's data from a SQL 2000 database table. I have configured it to generate the Update/Delete commands, which look correct. I then have a GridView that is using this SqlDataSource to show the data with "Edit" & "Delete" buttons (the default ones from the GridView). My problem is that while all commands (Edit, Delete) work on my local server, they do NOT work on my live server. In my connection string, I specifiy a username and password like this:
<add name="Project_Management.My.MySettings.WebReportsConnectionString" connectionString="Data Source=Karlweb;Initial Catalog=WebReport;Persist Security Info=True;User ID=VbUser;Password=VbUser" providerName="System.Data.SqlClient" /> I have access to change the permissions on my production server, so I gave this "VbUser" every allow permission I could find and still I could not Edit or Delete records. What I mean by they "do not work" is that when I click the Edit button, the GridView switches to edit mode, but when I click Update, the changes are not written. When I click the Delete button, the page just refreshes and the record is not deleted. As this is working on my local server, I think the problem lies in some permission or configuration of the server. Does anyone have any suggestions of where I could look or what to change? Thank you!
Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!
i have a table for storing username and password. the following are the fields in table ID -int UserName-nvarchar(50) Password-nvarchar(50)

Hi All I am using SQL server Database in one of my table there is a column which is set to Identity=Yes i.e., The ID is increment by one on every insert and if the insertion failed then the id generated goes off then in the next generation it uses new id ..........EXfirst insertion id=1 then in the second insertion if while adding data to other rows if i get some error then the id 2 is not used and when i correct the error and insert it then id=3? can any one give me the solution for this and NextWhen i delete the datafrom the table see the ids are upto 20 and i delete all the records from the table after insertion of new record the id will be 21plese help me in this
This may sound quite easy for you, however I am a newbie in SQL.
So I have an identity field, which I wish to increment automatically every time I do an insert. However the starting integer has to be the MAX value from another table.
So for example I am doing an insert in a #temp table INSERT INTO #temp(name, surname) SELECT name, surname from table1
Now the personId of the #temp table has to start from the MAX of table2 Ie SELECT MAX(personId) from table2
The SELECT MAX(personId) from table2 can also be NULL, ie the first time I am inserting, so I also have to cater for this scenario.
Hi all, i am deleting rows of a table and reinserting new ones. This table has an auto increment primary key. what is the function used to set it to zero each time i delete the rows in order to rebegin counting from 1 when i refill the table. Thanks in advance...
I created a new table in sql server 2005. Primary key is autoincrement value of 1. But when I insert the row, it increments by 4. It goes like 1, 5, 9 etc..what could be the problem ?how can I correct it? Do I need to reseed it? Thanks!!
looking for necessary syntax to alter table id to autoincrement adding identity statement, not sure on syntax for seed an increment, or if it is possible at all.
I noticed in SQL ODBC API reference that SQLGetTypeInfo would return true for AUTO_INCREMENT if a smallint field is defined as autoincrement. Is there a simple way to set a field autoincrement thru the SQL Server`s front end?
I have 2 tables: 1. CommandCode( id AutoIncrement_integer, name string ) 2. FooCode( FooID integer, CommandCodeID integer)
I have the following stored procedure
PROCEDURE InsertRows( CodeName VARCHAR ) INSERT INTO CommandCode ( name ) VALUES (CodeName)
Now right here I need to INSERT INTO the "FooCode" table using the same ID that was just added to the CommandCode table. How can I retrieve the last inserted autoincrement value for "id" in the CommandTable without doing SELECT id FROM CommandCode WHERE name = CodeName
END PROCEDURE
Is there an easy way to do what I described above? If possible I want it to comply with SQL standards (e.g. no MS SQL specific code)
Hi all! Does anyone knows how to get if a column is autoincrement or not, using the DatabaseMetaData in java, or using de JTurbo driver for it? Is there any other way to figure this out? :confused:
I am creating a trigger in SQL Server that will activate when my Athelete table has something "Inserted"
So far it works except for the fact that it won't insert a null into the Equipment_ID field. I need it to autoincrement, or do the last number + 1...
CREATE TRIGGER TRG_NEW_EQUIPMENT1 ON ATHLETE AFTER INSERT AS BEGIN INSERT INTO Equipment Equipment_ID, Equipment_Model, Equipment_Year, Equipment_Brand, Equipment_Color, Equipment_Condition_Rating) VALUES ('Big Spin','2016','K2','Blue','5') END; GO
Hi,I'm enclosed a snippet of test code which highlights my problem. The Storedprocedure insertValue should insert text into the parent, then insert othertext into the child table but the 2 tables should auto increment in sync(i.e. so that they both end up with the same id numbers). I've tried takingthe auto increment out of the child table but then I don't know how to getthe right parent id into the child table.Any advice appreciated - this is my first database, so I'm just in thelearning process really. Code follows:CREATE TABLE Parent(id INTEGER DEFAULT AUTOINCREMENT,parenttext VARCHAR(16),PRIMARY KEY (id))!CREATE TABLE Child(childID INTEGER INTEGER DEFAULT AUTOINCREMENT,childtext VARCHAR(16),FOREIGN KEY (childid) REFERENCES Parent(id),PRIMARY KEY (childID))!CREATE PROCEDURE insertValues(in p VARCHAR(16), in c VARCHAR(16))BEGINinsert into parent (parenttext) values (p);insert into child (childtext) values (c);END!call insertValues('from parent', 'from child')!select * from parent, child where parent.id = child.childid!
I have a table in my sqlserver 2000 that has a field IDNO. i want thisfield to be my primary key. however i don't want this field to use theautoincrement feature. when i access this table from vb.net and try toadd a record this field is autoincrementing. how can i disable theautoincrement of this field yet serves this as my primary key?thanks in advance
What I need to achieve is - everytime that a new line is inserted into an orderlines table part of the primary key will be the OrderId and the OrderLineId should be auto-incremented from 1 for each OrderId in the OrderLines table.
I know i can do this manually in my program, but i'm just wondering if theres a way to achive this in SQL Server?
Hy! I am a beginner in SQLServer and I have to design a database with a lot of tables (30-50 tables). I have to choose a primary key for every table between an autoincrement and a GUID. If I choose autoincrement after an insert statement (from the client) I will have to go back to the server to get the value of the primary key which is a waste of time. On the other hand if I choose a GUID I can create the guid from the client and send him with the other values of the new row to the server and I have not to go back to the server. I am aware of the disk space of a guid field so which is the best for me: GUID or AUTOINCREMENT? Thank you!
