SQL Server :: Passing Parameters For Select Query To Another Page
Dec 14, 2010
I have an asp.net site which includes a "search" page that queries an SQL table, then redirects the user to a "results" page where the results of the query are displayed. The parameters for the query are assembled into a string which is the SELECT statement. I've been asked to add additional functionality that requires a secondary search which takes place on the "results" page. How can I pass the parameters from the "search" page to the "results" page so that I can access those parameters in the code behind? Here's the first page code behind (I inherited most of this from another developer):
[Code]....
And the second page--it would be on line 51 that I would need to insert the parameters from the search above:
I've a requirement that I need to read an excel sheet programmatically using asp.net/C# and write the data obtained into a mysql table.The excel sheet contains something around 50 columns and 2000 records.I am able to read the data from the excel sheet and store it in a dataset.I am using the following code to write the data into mysql table.
for (int i = 1; i <= myDataSet1.Tables[0].Rows.Count - 1; i++) { MySqlCommand cmd = new MySqlCommand(); for (int j = 0; j <= myDataSet1.Tables[0].Columns.Count - 1; j++) { paramset[j] = myDataSet1.Tables[0].Rows[i][j].ToString(); cmd.Parameters.AddWithValue("val" + j, paramset[j]); } cmd.CommandText = "Insert into faqimport cmd.Connection=con; cmd.CommandType = CommandType.Text; int x=cmd.ExecuteNonQuery; }
When I try to run the above code I am getting 'Unknown column 'val0' in 'field list'' error.I understand that i am manually creating the parameters val0,val1,val2.....instead I am creating them dynamically using the integer 'j'.But I do not want to create around 50 parameters to insert data into the database table.
Also is there a way i can get the column datatypes from the excel sheet in order to create a new table in mysql with the columns in the excel sheet?
When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.
I am trying to show a Gridview that lists information in a database based on a query. The query takes a parameter of a string, how do you define what this parameter is. An example of the screen I am stuck at is:http://static.asp.net/asp.net/images/dataaccess/07fig08cs.pngAn example of the code i want to use is:parameter for my object data source select query = OBDS_Query_ParameterOBDS_Query_Parameter = str;
Sorry Im not sure how to explain it...For instance if I have a query that GetAllProducts(String userName); How do i pass or define what userName is when using the data gridview. I am using an Object DataSource and linking the data Gridview to that. I can do this without the object data source and strictly melodramatically like this:
I have a problem with SELECT COUNT query in ASP.net. I want to create CMS with articles which have categories (which have the option to be deleted). The problem is that I want to get the number of articles within the specified category so if there aren't any articles with the specified category I can proceed with the category deletion.I have the following code:
[Code]....
After I click the button "Obriši" (Delete) I receive the following error: "Must declare the scalar variable "@KategorijaID"." I understand that the problem is with parameter, but I don't know how to correct it to use it for both the "command" and "brisanje" SQLCommands.
I'm creating a webpage with serveral web controls to set search parameters for querying an SQL table. My plan is to use a TableAdapter to hold the query. If the user decides not to use one, several, or any of the web controls to filter their search, I want the SELECT to execute without complaining that it doesn't have parameter values. Should my SQL query look like
How do I do this? I want to search my database in listview form with the text from a textbox or an item from a drop down list which is on another page.
my company is hosting a reception for current / prospective clients, we have a list of invitees in a SQL database, using the following columns (ID, Name, Email, Company, Response). ID is a UID and Response is Int, others are varchar. by default, Response is '0'i want to generate an email that will invite each user in the database to the reception, and provide a link to pages on our website that will update the Response field to1 (attending) or 2 (not attending).
passing parameters from a datalist to another page.
this is how my app works:
i have a database ( access) a table with the following columns: id,title,desc,photo.
another table with the following columns: (startsin, endsin,price,tId)
on the first page (tourpack.aspx) i have a datalist, when user clicks on a button that is in the templateitem of the datalist, he will be transfered to another page called (showtour.aspx). what im trying to do is passing the ID parameter from the first page (table 1) to the second page (showtour.aspx) with the id number so he can see the specific details of that "tour" that are located In the second table.
how do I pass in parameters to the event args in the aspx page? or is that even possible? and how can I pass these parameters from my c# code to the javascript?
I have a web page that displays some data. When they click a submit button, I want to run a report. But I would like to pass the start year/month and end year/month values that the user already entered on the web page to the report. Here is what my url looks like when the report is displayed:
But my report displays the 2 textboxes for my StartYYMM and EndYYMM parameters as empty. What am I doing wrong? I did a google search and I saw something about using ReportServer instead of ReportManager. I notice at the top of the browser when I run my report, it reads "Report Manager - Windows Internet Explorer". Is this correct?

Now I am enabling Select in my GridView. I need to pass Entity_ID to another page and in this page I am showing more contents for this Entity_ID. How should I pick the Entity_ID value and pass it in as Query String? I have this code:
I am using following pivot query but not getting result as single row getting as 4 rows.
One more problem i am unable to pass dates as parameters to storeprocedure something like this
select [@date] .
SELECT 'Forecasted' AS HeadCount, [8/1/2010], [8/8/2010], [8/15/2010], [8/22/2010] FROM (SELECT * FROM TblEmpCount) AS SourceTable PIVOT ( SUM(EmpCount) FOR StartDate IN ([8/1/2010], [8/8/2010], [8/15/2010], [8/22/2010]) ) AS PivotTable;
I am getting result as 4 rows but i want result in single row like this
I'm having an aspx page with 2 frames, one is the header and the the other one is content frame which i'm trying to load it dynamically. Everything is fine. Let me explain my scenario
On the header frame i'm having 5 link buttons and when a link button is clicked i'm passing a hardcoded Page URL to the frames containing page and then trying to load that page in the content frame.
Below is my code, Everything as far as i know are in right place, but i cannot see the page in content frame..
Header.aspx.cs
[Code]....
Then checking frameURL querystring in default.aspx page load:
[Code]....
when the querystring is null, the SiteSummary.aspx page is getting loaded in content frame without any issue, but when there is a querystring value the page is not being loaded. Here is my Default.aspx page
i have been having trouble trying to find out what is wrong with my sql select query... i wanted to select a sessionID by comparing the tourID and dates. the dates datatype at the database is datetime and the value of itemSessionDate is in string. i tried to convert itemSessionDate to date and dateAndTime but it gave me mm/dd/yyyy while the date in my database is dd/mm/yyyy hh:mm:ss. so i thought i can try using the itemSessionDate string as it has the same value as the one return from the database. but it keeps on goin to the if not reader.hasRows and quit the statement
* 100 AS PERCENTAGE FROM support.SRFILE INNER JOIN BSFLBWF AS BSFLBWF_1 ON BSFLBWF_1.Incidentx = SRFILE.SRONUMBER WHERE (BSFLBWF_1.Closex IS NULL) AND (BSFLBWF_1.DedTypex = 'School' OR BSFLBWF_1.DedTypex = 'LAN-MLE') UNION ALL
The rest of the query continues as the above albeit selecting the same data from different tables and works fine.
The issue I have is that I want to Select some more data (another SELECT query) but with a different Where clause e.g. WHERE (BSFLBWF_1.KPIx NOT LIKE 'KPI%' OR BSFLBWF_1.KPIx NOT LIKE 'Proactive%') AND (BSFLBWF_1.Availabilityx LIKE '')
The problem is that this WHERE clause returns data which the above in bold has null values for (and thus doesnt work). Im still selecting the same data its just the WHERE Clause has changed. Is it possible to run such a query? If so, can it be done via a sub query?
I have an SQL 2005 db with a table named "industry_suppliers."
I've created a query to enable someone to search this table using 3 parameters.
The results need to be grouped by "product_description" (which is essentially a category). When displayed on an .aspx page, for example, the results need to look like this:
Apples
Acme Apple Company Bradbury Orchards Oranges A1 Citrus Company Belfast Growers, Inc Bradbury Orchards
Notice how "Bradbury Orchards" is repeated under both categories. This is the result I want, EXCEPT in cases where someone wants to filter the search results by category. Let's say someone wants to search just for apple suppliers. The problem I'm having is that any record that appears under apples will also get listed again under any other categories associated with that record. So, searching for apple suppliers, the results are this:
Apples Acme Apple Company Bradbury Orchards Oranges Bradbury Orchards
I'm having trouble figuring out how to revise my query to avoid this problem.
I have partitioned a table and it has been partitioned according to an account id. ie also rows that have accountid =1 will be in A partition and all rows that have accountid = 2 will be in B partition. so now if i execute a query with where condition accountid =1 sql server will search only in A partition. Suppose if i add another condition to it ie where accountid=1 and place="aaa" will this query search only A partition or the entire table?
I have stored procedure which selects records from an SQL table based on a bunch of user-input parameters.Just discovered that if a record in the table has null values in some of the columns (I haven't figured out which ones yet), then the SELECT is not returning the record (even if it satisfies all the parameters).The SELECT statement is supposed to allow for nulls, and I've been over it a bunch of times and am not sure what I'm doing wrong.Or do I need to get rid of all the null values in the SQL table, and prevent new ones from being introduced?
