DataSource Controls :: Row Count Shows 1 Record But There Is No Record In Database Table
Jun 24, 2010
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?
<asp:SqlDataSource ID="totalcount" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT COUNT ([CID]) FROM [WWAMembers] WHERE([CID] IS NOT NULL)"></asp:SqlDataSource>
how do I get the totals displayed with label or other control?
I am creating an album using the following stored procedure, which returns the primary key for the newly created record:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[fpa_sp_albums_update_insert] @album_id int, @album_name nvarchar (50), @album_descr nvarchar(250), @album_img_cover_id_FK int, @album_creation_date date AS If @album_id > 0 UPDATE [fpa_albums] SET album_name=@album_name, album_descr= @album_descr, album_img_cover_id_FK = @album_img_cover_id_FK, album_creation_date = @album_creation_date Where ((album_id = @album_id)) Else INSERT INTO [fpa_albums] ( album_name, album_descr, album_img_cover_id_FK, album_creation_date) VALUES ( @album_name, @album_descr, @album_img_cover_id_FK, @album_creation_date) Return SCOPE_IDENTITY();
I execute the above stored procedure using the SQLHELPER. The VB.NET code for the page is as follows:
[Code]....
However, the createdAlbumID always shows -1 instead of the id for the newly created album.
sometimes learning asp.net feels so heavy handed compared to some of the general purpose scripting languages like php. for examples, all i want to do is create a sql connection that pulls a row count and displays that number. I don't need a grid, list, detail page, etc., nothing this heavy... a simply query that will display a simple bit of text. for the life of me I can't figure out how to do it. Using these controls, I'm not in the code behind with the query, so I wouldn't attach this to a label (or would i), and there's nothing i see in the toolbox that does what i want. Perhaps i'm too accustomed to php but it feels like with asp.net, major things are simple, and simple things are hard.
I'm not sure if I'm using the correct SQL for what I need. Well, I know that I am not because I'm not getting the results that I expect.
I have a table of products and it has a productID field and a setID field.
Products can be grouped together by making the groupID the same for the both of them.
I have only @productID parameter. My goal is to get a list of products minus this product and any other product that it is grouped with (ie..setID is the same).
Here is the query that I wrote because it has worked when excluding products from another table. I used the explicit GUID and still nothing.
I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
I want to retrieve the data from the last record of a table. For eg: I have sorted the data in my table and want the value from the last record? How can I do that?
Is there a way to check that "saving" data to a table was successful and then do something after that?
I would like to duplicate a table record but not all the columns.For example, Select from "TableA" Where recordid='1' AND insert into "TableA" All values except "col2" , "col3". I hope you got the idea. Could you please advise me what is the cleanest approach to get this done.
I have been able to successfully read a row of data from an SQL table using two column parameters. Now I would like to update this row with new information. Is this possible since the reader does not specify which row was read with the 'reader.Read();' command?
i Am using Special character while insert in the database. When i user single Quotes('), it shows an error that "Unclosed quotation mark after the character string" How can i over come this issue. But i want to insert the special characters"
I have 3 pages, one to add a category, one to edit the category, and one to delete the category. The add and edit work fine. The delete is not working for some reason. I click the link on my site to delete it, and I'm just staring at the green bar in my browser taking a long time. The add and edit don't take long at all to perform their function. I'm thinking this is a connection string issue, but I don't see how it can be the case. It relies on web.config for it just like the other pages. Following is the delete page code behind and also delete cascade from the business logic area. After the page refreshes, I'm not getting any diagnostics or error messages which I have in the code. Doesn't this have to mean a db connection issue?
I'm a beginner in programming and also to asp.net. I am trying to insert a row into an sql database using vb.net but I keep getting an error whenever I try to execute the code. I have read other post but I do not understand the solutions or how to place them within my code. Here is my stored procedure and vb.net code.
Is there anyone know the reason why that there duplicate data in the database most of the time the information is same like name,description.but the unique id is different and the date time is got different millisecond.I confirmed that there r no loop condition on the code.

copying some data from an existing remote database(SQL2005) to an existing local database.First - I have very little experience in this area. I'm using Visual Web Developer 2008 (VB). Currently if I want to update some data in the local database I do something like this:
Dim conn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("CCCdbConnectionString").ConnectionString) Dim cmd As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand("UPDATE [Orders] Set [OrderStatus]
I want to retrive thousands of record from the database. Please tell me the the most efficient way to do this. I am using sql server. I want to bind A gridview with these records please let me know the most efficient way to do this so that the loading time for the page is reduced
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.
when i want insert a record i see an error like this Can't perform Create, Update, or Delete operations on 'Table(MainMenuLink)' because it has no primary key. with this codes:
MyLinqDataClassesDataContext db = new MyLinqDataClassesDataContext(); MainMenuLink li = new MainMenuLink { Link = "www.tprogrammer.com", LinkSubject = "subject" }; db.MainMenuLinks.InsertOnSubmit(li); [code]....
