I've been having an issue with running an SQL select statement with a button. At the moment, my page has two buttons and allows both to run the gridview where my SQL data displays. In my asp page I have:
<asp:Button ID="btnGo1" Text="Search" runat="server" onClick="btnGo1_Click" />
In the C# code, I have methods for OnLoad and btnGo1_Click, but I'm pretty new to programming and don't know how to link the methods to the button I created.
i have a upload control that alllows users to upload files to the server. and a drop down list that shows the contents of the files in the folder.
And a button labeled execute.
The .txt i need them to upload will give insert queries that the server needs to run upon clicking the execute button.
What should i research in order to accomplish this task?
I am using MS-SQL & VB.Net
I have a SQL table that stores startdate and enddate. I want to run a query on that table every 10 minutes in order to check if the enddate is greater than today and if it is I would like to add a 1 to another column if it is not I would like to add a 0.
The below SQL query is running extremely slow. Im using this query on other tables and its processing about 5 rows per second. The below version is running 1 row every 10 seconds when @SQLNew is executed.
[Code]....
When doing a query e.g. "select ID from myTable order By SomeStringField" from SQL Developer my data the data are sorted correctly according to database settings:
Abc
abc
Bcd
bcd
But when using the System.Data.OracleClient namespace and a DbProviderFactory to create a DbCommand and use that to create a DbDataReader, the data is sorted case sensitive:
Abc
Bcd
abc
bcd
Is there some setting on the command which needs to be set? Can you even change the case sensitivity in the .net framwork, overriding the database settings?
I have a datasource (which is a query) that could run more than 30 secs. I want to show to a user an animated icon (I have it already) while the Gridview is waiting to return data.
I studied several tutorials and textbooks but all just "thoerectically" use a timer to simulate, without much application to real example above. How should I code it in the above real scenario ? In which event handler to put the code and what control (Update panel) to use and any sample code ?
I want to start a new thread to query a database while my web application continues running. I was under the impression that by using threads I can run the querying process independently while the normal web application page cycle carries on, but I could be wrong.
public class DbAsyncQuery
{
Dictionary<string, object> serviceResults = new Dictionary<string, object>();
public void UpdateBillingDB()
{
QueryAllServices();
foreach (KeyValuePair<string, object> p in serviceResults)
{
IEnumerable results = (IEnumerable)p.Value;
IEnumerable<object> sessions = results.Cast<object>();
DbUtil.MakeBillingDBEntry(sessions, p.Key);
}
}
public static string[] servicesToQuery = new string[] // Must go in config file ultimately
{
"xxx.x.xxx.xx"
};
public delegate void Worker();
private Thread worker;
public void InitializeThread(Worker wrk)
{
worker = new Thread(new ThreadStart(wrk));
worker.Start();
}
public void InitializeQuery()
{
Worker worker = QueryAllServices;
InitializeThread(worker);
}
private void QueryAllServices()
{
Dictionary<string, DateTime> lastEntries = DbUtil.GetLastEntries();
foreach (string ip in servicesToQuery)
{
string fullServicePath =
"http://" + ip + ":800/MyWebService.asmx";
//object[] lastEntry = new object[] { lastEntries[ip] };
object[] lastEntry = new object[] { new DateTime(2011, 1, 1, 0, 0, 0) };
object obj = WebServiceHandler.CallWebService
(fullServicePath, "MyWebService", "GetBillingDBEntries", lastEntry);
serviceResults.Add(ip, obj);
}
}
}
It seems to basically stall and wait to finish the query before loading the page (which can be thousands of rows, so it takes awhile). I put this in the following section of Global.asax:
protected void Application_Start(object sender, EventArgs e)
{
DbAsyncQuery query = new DbAsyncQuery();
query.UpdateBillingDB();
}
This is one of my first web pages, and I'm new to threading. I understand there is a difference between creating your own thread and using the ThreadPool. In this method, I am using my own thread, I think. Not sure if that's the best way. The querying process can be completely independent, and its only going to occur on scheduled intervals (every 8 hours or so). The user doesn't need to have up to the minute data, so it can take awhile. I just don't want the site to wait for it to finish, if that's possible.
I have one query which is not responding even after 4 minutes. But same query is when called from asp.net pages (though stored procedure), responds within 10 seconds. My Query:
[Code]....
I don't want to know the ways to optimize the query as I have already changed the query and now it responds within fraction of second. I just want to know that, why it was not reponding after 4 minutes in SQL Management Studio and responds in just 10 seconds when run from asp.net through stored procedure. I am using SQL 2008 Express with Advanced services and .NET 3.5.
I have a query which is returning records like below which returns a list of tasks with a corresponding task type. there is a task table (wh_task) and a task type table (wh_task_type). What i want to achieve is a count of all the tickets per ticket type. So at the end of the query i will have a total for Administration / Maintenance tasks (1) and a total for Routine Maintenance Tasks (3). ** and all the other types *
There are many different types of task type so I dont want to have to hard code it. Can count all the occurencies of the different ticket types.
Task Name
Task Type
Date Completed
SBS Server C drive running out of space
Administration / Maintenance

I can also get wh_task_type_id.

I am running a sql script which Inserts 500 rows and after each insert, it calls a stored procedure which diplays result in the results window. So after executing 100 rows, it throws an error that maximum number od results in the results pane has reached its limit but the query executes successfully. How can we disable the stored proc output to not display in the results pane. I do not have access to the stored procedure.
View 4 RepliesOne of my peer wrote a query based on multiple tables using joins. One of the table is in a different database The query was taking much time
1. Create an SP
2. Create a temp table and copy all records from the external db
3. Avoid using Left Join as much as possible and use Inner Join
4. Create and use indexes
5. Remove tables/columns that are not necessary
In this scenario, I would like to suggest to use Covering Index, but how can it be created for multiple tables and a temp table?
We need assistance with a portion of a major web application project scheduled to begin user testing within 10 days. The troublesome part of the code calls an external application when a button is clicked in Web page. When run from a command prompt or bat file, the external application, App.exe, runs perfectly producing the desired result. We created a test page and a small console application, Con.exe, to test the button code with a known quantity. The test application runs perfectly when the button in the Web page is clicked. However when we change the code to run App.exe instead of Con.exe, the App.exe code will not execute. We even tried creating a bat file to execute App.exe. Like the exe, the bat file executes from the command prompt or when double-clicked,but fails to run when called as a process from the button click event. Can anyone assist us?

View 8 RepliesI have a web service that runs a query (from C#) to get a dataset from sql server. I get the following time out error. Googling on this error says, you can set the timeout on command object. But I am not using command object to set the timeout. This is the code I am using to get the dataset.

I have a grid view with the delete option enabled. When the user clicks on delete, that entry in the database is deleted. However, each entry in my database corresponds to 2 images on the server. When that entry in the database is deleted, I also want to delete the images. (the images consist of the ID for that database entry plus "right.jpg", and "left.jpg") Is there a simple way to do this? My thoughts are that I need to run some additional code when the user clicks the delete button, but how can I trigger this code?
View 2 RepliesI am executing a long-running Oracle stored procedure from .NET. The procedure takes about three hours to run. Ideally, the user should be able to kick off the procedure, close the browser, and come back later to check the results.
The problem is that the connection to the Oracle procedure is lost after exactly an hour. As you would expect, the Oracle procedre runs to completion if it is executed from SQL Plus. Strangely enough, it will also run to completion if I run in debug mode on my local machine (I start two threads, one of which executes the procedure. I set a breakpoint on the second thread).
Here is my connection string:
data source= (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=serverx)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TestSID)))
Some relevant sections from web.config:
<sessionState mode="InProc" cookieless="false" timeout="3000" stateNetworkTimeout="72000"/>
<httpRuntime executionTimeout="18000" maxRequestLength="2097151" />
Any thoughts as to why the connection is being lost in exactly an hour, and what I can do to maintain the connection until the procedure finishes?
I have to start working in a project. this project is already done 80%. Now i have to do further work in this. i want to know on some button click what database operations are performed in our sql server.
View 3 RepliesI'm trying to figure how to on a submit button execute an sql file.
We have a job recruiting application, and for the subsidiaries companies they all have their own database setup for the jobs. At night the application has a consolidator script built in to pull all the jobs posted in those companies and load the posting into the parent companies website job listing. This listing will then point back to the Subsidiary website for the applicant to apply.
The issue with that script is the time it took to execute which is 20hrs to run as a scheduled task. We have created a more efficient script and would like to place a submit button in the admin panel for the HR recruiters to click which will automatically upload their updated job listings to the parent company.
So what would be the proper coding framework to use on the submit form to execute our new consolidator sql script?

I have a gridview set up with a button that when clicked I want it to send a unique value to a listview which is set to receive the value in a parameterized SQL query. I forgot how to set the button up in the GUI to take the unique value and put it in a query string and send it to url. I would like to use the GUI just to get more familiar with it. I know this is easy but I gortgot how.
View 5 RepliesI tried researching on this topic, but I could not find enough information. I could find a lot of posts which suiggest how to "update the gridview with buttons outside the gridview", but I could not find the one suiting to my requirements. I am using a mysql database.
So I have two ASP.NET calendars, one for start date and the other for the end date. When you click on start date calendar, the start date appears on the STARTDATETEXTBOX. When you click on the end date calendar, the end date appears on the ENDDATETEXTBOX.Both the dates appear in MM/DD/YY format.
I have a button, called GenerateReport, which generates a report. I also have a gridview. The gridview has a column,when_ordered, which is of the datatype DATETIME.
I would like to have a SQL query behind the button, which generates only those fields from the when_ordered table that are between the start date and the end date. Something like "SELECT * FROM tablename1 WHERE calendar1.SelectedDate < when_ordered && calendar2.selectedDate > when_ordered.
i put this in a grid so that only one of the rows would have the txt box in it, it works ok ie the txtbox only shows up for the row with 1005 as the ID, but for some reason the query string for each row for the last element in the row, ie an AddToCart image button i have at the end of each row in the grid is not coming out right, ie the query string is missing when the page posts back for all but the last row of the grid which coincidently is the row with the 1005 ID, (the rendered code is shown way down, i apologize for the length of it ) here is the problem line. NOTE when i take the code out of the gridview on row data bound event then the page post back fine and the query string is there, but when i put the code back in the row databound event for the grid then the query string vars and values do not get posted back.

View 4 Replies1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
