Web Forms :: Impact Of Command Timeout Property While Working With Command Class
Jun 3, 2013
I am working with odbcCommand class, in one case I got error that QueryTimeout Expired. Even though this SP is taking only 3-4 secs in DB to execute these specific values, When I set the CommandTimeout=0, then it worked fine.
1)Is it necessary to always use this property while working with Command Class.
2)If it is not suggested to use, but still if I use it then how it will impact the performance.
Below is my code sample.
OdbcConnection conObj;
OdbcCommand cmdObj;
OdbcDataAdapter daObj = new OdbcDataAdapter();
public DataTable GetIFAContractNoteData(string RecipientIDIFACN, DateTime BatchDateIFACN, int TransmittalReportIDIFACN) {
conObj = new OdbcConnection(GlobalVariables.strDsnName + ";" + GlobalVariables.strDsnDataBase + ";" + GlobalVariables.strDsnUserID + ";" + GlobalVariables.strDsnPassword);
My stored proc execution runs perfectly on local developement environment, but in QA environment it just returns an error after 5 min.s(My stored proc. takes arround 15 min.s to complete), when i run my Stored proc from query analyzer it runs perfectly in 15 min.s.
I tried to debug the code by pointing my local code to QA database, but that didn't give any error and ran perfectly. So i suspect there is something like commandtimeout happening in QA environment. Then i went on to check code at QA environment, it passes commandtimeout = 0 to the command object which means infinite.
What is the difference between connection timeout and command timeout?
In our application sometimes it is showing a timeout error. When we increased the command timeout value to 100(from default 30), its working. Is there any issue in increasing the command timeout value.
I want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
I was working with SSRS in windows application,when I got this error "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I have made the property of Dataset(.xsd) EnforceConstrints to False and error gone. Whether it will impact anywhere in the application in the future or it wont have any impact.
i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource(); sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString(); sq.SelectCommandType = SqlDataSourceCommandType.Text; sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1"; string result = sq.Select(some overload that's stopping me);
I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
I have been looking through the event viewer on our server and can see quite a few people with this error but I can't replicate this myself but it is causing issues for people viewing our website is there anyway I can "initialize" Command Text property?
UPDATE
So I have this query
datelistquery = "SELECT DISTINCT property_id, ' - Sleeps ' + cast(number_slept as varchar) as combsleeps, number_slept FROM openquery ("+Application("hpbDsrc")+",'SELECT property_id, number_slept FROM web_details WHERE part_full_flag = ''F'' AND location = ''"&Session("TenChosenLocCode")&"'' AND property_id = ''"&Session("passedPropId")&"'' AND pets_yn like ''"&Session("TenPets")&"'' AND number_slept >= ''"&Session("TenAdults")&"'' AND year_week = ''"&Session("TenHolStDateHP1")&"'' AND on_hold = ''NO'' AND booked = ''NO'' ') ORDER BY number_slept, property_id"
So should I put at the start sqlCommand.CommandText(datelistquery) = "Select Distinct...."
I have a gridview. Every time i click on the Edit command, it caused the Delete command fired. This gridview works fine on the test site, but it does not work on the live site.
I have this code that hides a column in a gridview. (The column houses another nested gridview).
[Code]....
The trouble is that if I click the select link on one row that action to hide is carried out on all rows. How can I set this up so that it only hides the row that is selected?
I'm a novice programmer and I have this situation: I have a nested Gridview, and I want to be able to DELETE the records in the nested Gridview. I have no problem inserting new records with the nested gridview, but it does not execute the DELETE Command on the SQL Datasource. I checked that the DATAKEYNAME on the nested gridview includes the the parameter that is used in the DELETE SQL Command on the SQL Datasource for that Gridview. But it seems to me that the parameter value is not being passed to the SQL Datasource by the nested gridview. Maybe I need to use a difference approach to execute this on a nested gridview compared to a regular gridview.
I have this code works perfectly in VB .NEt, not I am trying use the same code in ASP .NET and when it gets to this line, its doesn't move forward in the code to the line after

I have a GridView and a SqlDataSource, which I have set to automatically generate Delete/Insert/Update statements. I then just enabled Deleting on the GridView, and usually away I'd go. For some reason though, the row is not being deleted - the page is posting back but the row is still there. When Delete is clicked, RowDeleting does fire though. What possible causes could this be?
Edit: SELECT command: SELECT id, templatename, CASE WHEN type = 'W' THEN 'Weekly' WHEN type = 'M' THEN 'Monthly' WHEN type = 'Q' THEN 'Quarterly' WHEN type = 'S' THEN 'Six-monthly' WHEN type = 'A' THEN 'Anually' END AS TypeText, CASE WHEN invorcred = 'I' THEN 'Invoice' WHEN invorcred = 'C' THEN 'Credit' END AS 'InvOrCredText', nextinvdate, lastinvdate FROM InvoiceTemplates WHERE (sageaccount = @sageaccount)
I have a very simple and stupid problem but I'm unable to find a solution. I'm trying to create folders and files locally through my code, however I get a permission exception when I try to write in a folder in my application. Normally I'd run this on a remote server, and ask the system administrator for writing permission on this specific folder, but I need to run this locally for the moment.
If I navigate to the file in windows explorer, and right click the folder and click on Properties, I can see that it's set as Read Only. However when I try to disable this tickbox and click on Accept, nothing happens. It ignores me, and next time I open the Properties of this same folder, it's still marked as Read Only.
I've googled this and found a solution which implies using MS-DOS and a command named "attrib". This is not working for me either. I also read about adding an ASP.NET account on my PC and granting the right permissions to this, but I'm not sure how to do is.
ave never used ajax.... I'm currently putting together a little web app that basically calls a program on the server itself (a command line tool) and displays the output to the web page.When the command line tool is run from the command line, it outputs status messages as it does it's thing... as it is now, my page just displays all the output when it's done. What I would like to do is show each line of output on the web page as they happen, just like when run from the command line. I'm guessing ajax is what I need... can anyone point me in the right direction for this specific scenario (user clicks button, output streams to web page as it happens without full page post backs)... a good example would be how ping.exe displays it's output on the command line
