SQL Server :: Timeout When Calling SqlDataAdapter.Fill (DataSet)?
Sep 13, 2010
This issue has stumped me for a while. Hopefully someone here can give me some insight.
When my site runs the following code it works just fine 99% of the time.
[Code]....
The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.
When I run the exact same query in the Management Studio query window it takes 1 second.
what I can do to get the same performance from .Net as I am getting from Management Studio?
I am VB.Net Windows Application Developer Now i am going an ASP.Net Application. So, the Problem is that in Windows Application i Code this Project like given Below Actually i am Using SQL Server as DataBase and Store Procedure as Query.Becuase i had tried to control the ASP.Net Data Grid with Loop and i Failed to Control it with this method
Private Sub btn_Ok_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles btn_Ok.Click Fill_dataset("Sel_MovNames", "Tbl_MovNames", Convert.toint32(cmb_MovID.SelectedValue)) [code]...
I am trying to use a SqlDataAdapter to fill a DataTable, which I use as a data source to a DataGrid. The query is fine, at least when I run it manually in SSMSE. When I do the fill operation, the table gets the right columns, but no rows. The most frustrating part of this is that the code is identical (with a different query) on a different page. I cannot post the query, but my initialization code looks like this:
SqlCommand areaDAC = new SqlCommand (areaQuery, connection); areaDAC.Parameters.Add (new SqlParameter ("@param", System.Data.SqlDbType.NVarChar, 50)); m_areaDataAdapter = new SqlDataAdapter (areaDAC);
At this point, table has the right number of columns and no rows. I know the parameters are being added correctly, I know that data exists for the given query.
I am not clear when do I want to use a webservice over a sqlDataAdapter for dataRetrieval. I want to populate a repeater control which I have been doing from a dataTable that I fill from a sqlDataAdapter. Is there criteria when I would want to use a webservice to fill my dataTable?
I have a theoretical question.i have a function in DAL that does a select sql query. and these are my questions:
I was told that it's not appropriate to pass datasets between layers. so how should i pass the results? which value should i return to the BLLBAL (i thought of a List<>).? and to the presentation layer.
currently my implemention is like that:
SqlCommand cmd = new SqlCommand("getRequestById", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@requestId", rId)); SqlDataAdapter datAdp = new SqlDataAdapter(cmd); DataSet ds = new DataSet(); datAdp.Fill(ds,"getRequestById"); List<String> rs = new List<string>(); for (int i=0; i<11; i++) { rs.Add((Convert.ToString(ds.Tables[0].Rows[0].ItemArray.GetValue(i)))); } return (rs);
is it better to create xsd file in VS2010 with only fill (all other implemtation i'll do on my own) property.
I added New Item, DataSet, over that i added tableadapter with stored procedure. i declared that it will do only the fill property(without returning the data). i want to implement all the other properties by demand in my way.
i wrote in the dal test.getRequestById1DataTable dt1 = new test.getRequestById1DataTable() how can i get the data and pass it between the layers?
i run this and i want to fill textbox txtFname with data - but it dont do nothing
using (Conn = new SqlConnection(Conect)) { Conn.Open(); SQL = "SELECT * FROM MEN where id = '" + txtBAR.Text.Trim() + "'"; dsView = new DataSet(); adp = new SqlDataAdapter(SQL, Conn); adp.Fill(dsView, "MEN"); adp.Dispose(); txtFname.Text = dsView.Tables[0].Rows[3][0].ToString(); txtFname.DataBind(); Conn.Close(); }
I have an intranet application that is calling a webservice (code below). The webservice calls a stored procedure in q sql server 2005 that again does an openquery on a db2 (AS400) machine. The stored procedure is returning a temp table. On the call to the webservice I am getting a time out. At this point if time out the web service is still running and I can also see the query is in the program stack on the db2 machine. The query itself can take up to 20-30 minutes as it is reading 3 mill+ records. If I call the web service directly I get the result returned.
Code: Dim getOrderDetail As New localhost.OrderDetail myDataTable = getOrderDetail.GetOrderDetailRecords_DataTable(myUserId)
I have excel file.I want to fill dataset from that excel file & Have to fill the database. I m able to read the excel file,but there is one problem with column whose datatype is Date.
[Code]....
I have attached the excel file (Pic1).
In Pic2,I have attached the snapshot of dataset that is filled.
I want to develop some reports using RDLC and for that i am trying to make a DATASET using a sqlserver stored procedure which is based on dynamic SQL. and ends the procedure like this.
[Code]....
As you can see at the end its executing a sql at the end so my dataset is not coming up with the columns this procedure is returning.. populate these dynamic columns in dataset so i can build a report based on it.
I have several stored procedures in my database, some of them have params, some have no params. I tried to fill a business object by calling the stored procedures, but failed so far. How could I do that dynamically? Later, I want to use this object as a datasource for a report...but thats the next step. The important facts are:
different stored procs return different amount of columns stored procs can have params, but its not required
then use the following code, there is nothing to see after running. is it need to add field object into crytsl report corresponding to the field in data set. But i do not know how to add in this situation which is not connected through crystal report.
Lets say for example i fill a dropdownlist with the articles, and the selectedValue is the Articles.Id . I want to get for example, the Title of an article, that has ID=2, for example and fill a textbox with that data.
to get limited records using this method? i.e. by filling dataset using adapter and providing min and max record limit?I wish to do custom pagination using this method.
Well I Am Working On A Client Project Who Was Earlier Using A Software Developed On Foxpro database And Now I Am Developing Advanced Reporting Based On Same Data Of Existing Database
I Am Prohibited To Create New Database, I Have To Use Existing Database Now Problem is That There Is A Report Which Require data from multiple database
database are related Like This
Database (a) 1 Column is Common in Common In Database (b)
database(b) 1 column is common in database (c)
like that
what i am doing is that, I First Filled A Dataset With Required Value Then I loped This Dataset Row For Value On Which I Have To Get Data From Another Database Again I Stored new data in another dataset and After Looping, I Merged It With Previous One.
I am using a Strored procedure which inserts data in to global temporary table and returns the result sets to Client. when i execute procedure from SQL Plus its working.where whene dataadapter.fill command is executed Invalid ROWID exception Is thrown.
Should i use dataset in code behind or SqlDataSource on the form designer to fill or bind a DropDownList in my asp.net page I am currently using SqlDatasource on the form and i bind the control to MySqlDatasource because i find it is very easy and to much faster but somebody told me to use dataset from code behind because of security and performance
when my website allow user many connectionstring by text to connect database anh retrieve data. But when user define very may wrong connectionstring. So Method in DAL dataset.Fill() takes a longtime to throw exception.So mywebsite will be die.
I want to method dataset.Fill() throws exception immediately when a connectionstring wrong. How can i do that?
I'm new with programming. I have a GridView that have the specific user data. When the user log in I retrieve the data for that specific user. All I need is; How do I make the gridview get the data of the logged user using a datatable that has a query. Just bind it with the datatable.This is some code that other programmer made, I continue his work.
