I need to display something like "Results x-y of z." The problem is, I can't figure out how to get the right value for z.
I am using SqlDataAdapter and Fill()ing a DataSet with subset x through y of the result set. How can I get the right value for z?
Hi,
I got a weird problem. I've created a sp that takes in the query analyzer 7 seconds to run. When i put in my code dataAdapter.Fill(dataSet.Tables(0)) it takes forever to finish!!
What's going on?
Any thoughts highly appreciated.

I'm working in a ASP.NET 2.0 application with a SQL Server 2000 database on the back end. I have a strongly typed dataset in the application that calls a stored procedure for the select. I'm having trouble filling the dataset at runtime though.
I am trying to use a character string query because I setup different columns to be pulled from a table each time and in a different order so my T-SQL looks like this:
set @FullQuery = 'Select ' + @FieldsinOrder + ' from tblExample'exec (@FullQuery)
This works fine in query analyzer. The results return and display correctly. However, when I run the application, the dataset does not get filled. It is like the results do not output to the application.
If I change the query to be a normal select it works. For example:
select * from tblEmample
That works fine. What is it about a select query setup as a character string and then executed that ASP.NET doesn't like?
hi,
i want to execute a finctionX() based on the returned resultset of SQLDataSource. For example, if the SELECT command returns nothing based on a specific search criteria then I want to execute functionX(). Currently, I have a string that displays "No Result" in the GridView in such case.
How to catch the resultset of SQLDataSource?

I'm using Report builder 3.0 to create a report. In the design, datatset query i have a sql to calculate difference between two dates (date1-date2) as processing time. I have this (processing time ) ONLY in my ORDER by clause and when i execute the statement it does exactly what i was looking for , however when i run the report the sort order is not delivered. I checked each column tablix properties and the sorting order is set for Processing Time.

View 2 Replies View RelatedI'm trying without success to do a select command against the dataadapter and then fill a dataset. I'm using VS 2008, and I've set my project to the 2.0 framework. What is wrong is I get an empty dataset (The count on the dataset = 0. )with the code below. The database is connecting fine, so I assume it's something to do with the commandtext. The database is SQL CE 3.5.
Any ideas would be appreciated.

View 1 Replies View Relatedthis may seem like a real newbie question, but I got no clue how to solve this problem. When I was working in Visual Studio 2003, whatever I wanted to fill a dataset with data, I was using a SqlDataAdapter that I created like this adapTest.Fill(dsTest); But now, I cant seem to find the sqldataadapter anywhere, I can just create (on the visual interface of one of my page of my aspx project) dataset, but cant find anywhere a adapter to put an SQL instruction into...maybe theres a new way to do this in Visual Studio 2005 that I dont know about. Im not sure if I was clear enough, but what I want in the end is to be able to use my dataset like that dsTest.Tables.Rows[0]["a column"].ToString()by filling the dataset with data like I was able to do in VS2003. Thanks for taking the time to read this.
View 3 Replies View Related Hello,
I have been reading about how you shouldn't build dynamic SQL statements (see TextBox1.Text in line 3) and should use parameters instead, but I haven't yet found how to create a SELECT statement with a parameter that fills a dataset. If anyone can show me the correct way of doing this I would appreciate it so I can add it to my code snippets for proper coding practices. Thanks in advance for any assistance.
string strConnectionString = ConfigurationManager.ConnectionStrings["sqlConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(strConnectionString);
-> string sqlSelect = "select * from customers where city = " + "'" + TextBox1.Text + "'";
SqlDataAdapter da = new SqlDataAdapter(sqlSelect, myConnection);
DataSet ds = new DataSet();
myConnection.Open();
da.Fill(ds, "myDataset");
myConnection.Close();

I have an off the wall situation that occurs when I try to fill a dataset that has already been filled with data. The issue with the DataSet in and of itself was a mistake I made and is not relevant to this forum.
What would appear to be relevant though, is the fact that after the exception was caught, I could not longer query data from the SQL Express database that was included in my project. In other words, when I tried to view the data in the IDE by selecting "Show Table Data," I received a message telling me that the query was running and eventually it timed out.
To fix the problem in my application, I obviously eliminated the bad code. But to be able to query the database again, I had to physically restart my computer (yes, I probably could have restarted the service, I know).
So my question is, has anyone run into this phenomenon before? If so, is there a way to prevent it other than the obvious, which is to clear the DataTables in my DataSet before filling them?
It's not that big a deal, but it is kind of a pain in the rear to have to restart everything because of a stupid coding mistake on the client side while I'm developing an app.
This is the first time I've tried creating an "execute sql task" with a "full result set".
I've read in the documentation that I must set the resultname to 0, which is done, and that the variable must be of type object. Also done.
[Execute SQL Task] Error: Executing the query "select * from blah" failed with the following error: "The SelectCommand property has not been initialized before calling 'Fill'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Has anyone else had success with a full result set?
Thanks,

Hi there !
Thanks for taking the time to read this thread.
I don't know whether anyone has this problem, but I am definitely not using the right keywords to search for a thread.
My situation is this...
I have a dataset that has values to fill cells to multiple tables in a report.
However, I only want to select specific data from the dataset to fill textboxes and others.
I cannot change the stored procedure, but the sample of the data is shown below:-
Row Stat Val
0 dtRpt1 02/01/2005
1 Value1 1
2 Value2 2000
3 dtMailSent 02/28/2005
4 Value3 0
5 Value4 5
6 Value5 658
I know it looks weird, but the row really represents which "row" or textbox is it to fill with the Val. The Stat Column is just a way to make sure that I am filling the right values.
so my new report would have multiple tables to denote different categories.
In my first table, I tried putting the cells as follows:-
(expressions are highlighted in italics and bold)
TextBox1 =IIF(Fields!Row.Value =0, Fields!Val.Value,"")
Table1
Column1
DetailRow1 =IIF(Fields!Row.Value =1, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =2, Fields!Val.Value,"")
Table2
Column1
DetailRow1 =IIF(Fields!Row.Value =3, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =4, Fields!Val.Value,"")
DetailRow3 =IIF(Fields!Row.Value =5, Fields!Val.Value,"")
DetailRow4 =IIF(Fields!Row.Value =6, Fields!Val.Value,"")
I only expect this report to print out one page holding the previous values.
However, it ended up printing like this
----------------------------------------------------------
Table1
Column1
DetailRow1 1
DetailRow2
Column1
DetailRow1
DetailRow2 2000
Table2
Column1
DetailRow1 02/28/2005
DetailRow2
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2 0
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3 5
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3
DetailRow4 658
------------------------------------------------------
I tried putting it into the headerrows instead of DetailRows, and it ended up printing the last value.
Is there anyway to do this ? print all the values out in one table ? I tried using textboxes, but I think I got my expression wrong.
Is this the correct expression ?
=IIF((Fields!Row.Value,"Dataset") =1, (Fields!Val.value, "Dataset"), "")
and it give me an error
The value expression for the textbox €˜textbox5€™ contains an error: [BC30455] Argument not specified for parameter 'FalsePart' of 'Public Function IIf(Expression As Boolean, TruePart As Object, FalsePart As Object) As Object'.
Appreciate any advice or suggestion for this scenario !
Thanks!

Hi all...I've set the DataSourceMode = SqlDataSourceMode.DataSet, and did a .Type return and found that it is actually returning a DataView. A component I am trying to avoid rewriting....requires a dataset that loops through the table, does some cool formatting to a datagrid and then rebinds.Here's the code that I'm trying to send the dataset to....maybe there's just a couple of changes that could make it work with a DataView? int i = 0; string prevsub = ""; while (i <= ds.Tables[0].Rows.Count - 1) { DataRow dr = ds.Tables[0].Rows[i]; string sub = dr["SubHeading"].ToString(); if (sub != prevsub) { prevsub = sub; DataRow newrow = ds.Tables[0].NewRow(); newrow["Title"] = "SubHeading"; newrow[columnName] = dr[columnName]; ds.Tables[0].Rows.InsertAt(newrow, i); i++; } i++; }
View 2 Replies View RelatedHi,
Running into a quirk with creating a new dataset in RS 2005.
The dataset is based on a SQL proc, which I can identify and execute in the Data tab page and see the correct results when matched against the same params in SQL Studio.
However, the DataSets window only lists a single field call "ID" under my available fields listing, even though I can see all the correct fields in the pane right next to.
The structure of the sProc is similar to many that I have create reports on previously.
Any suggestions would be helpful....

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC.
Tables I have are structured as follows:
SHOWS
showID
showTitle
SHOWACCESS
showID
remoteID
VIDEOS
videoDate
showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle,
(SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID)
FROM shows, showAccess
WHERE shows.showID = showAccess.showID
AND showAccess.remoteID=21
ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate.
Can anyone shed some light on where I am going wrong?
thanks

I work for a federal government client who restricts us to using virtual machines for dev work. Now the VM team has gotten MUCH more aggressive with "right-sizing" (which always means down-sizing) our virtual machines. I have a Dev server with 8 GB RAM and I need that much when developing, but I don't develop all the time. So I want it to look like it needs all that RAM before they bust me down to 1 GB, which they will do.How can I get SQL Server to use up all the memory I've allocated to it? Is there a relatively easy query to do this?

I hope I am not asking about something that has been done before, but Ihave searched and cannot find an answer. What I am trying to do is torun a query, and then perform some logic on the rowcount and thenpossibly display the result of the query. I know it can be done withADO, but I need to do it in Query Analyzer. The query looks like this:select Varfrom DBwhere SomeCriteriaif @@Rowcount = 0select 'n/a'else if @@Rowcount = 1select -- this is the part where I need to redisplay the resultfrom the above queryelse if @@Rowcount > 1-- do something elseThe reason that I want to do it without re-running the query is that Iwant to minimize impact on the DB, and the reason that I can't useanother program is that I do not have a develpment environment where Ineed to run the queries. I would select the data into a temp table, butagain, I am concerned about impacting the DB. Any suggestions would begreatly appreciated. I am really hoping there is something as simple as@@resultset, or something to that effect.

I am working on a school project and have come up against a bit of a sticking point. I am supposed to be creating a very basic OMS, the teacher themselves have said they do not know how to do this (in previous years it has all be done via Access) but apparently I am a lucky one to be doing it in SQL this year.
So I have 2 tables for products in the system
products
+-----------+------------+
|productid |productname |
|Int |varchar(50) |
+-----------+------------+
productdetail
+---------+----------+------------+------+------+
|detailId |productid |description |price |stock |
|Int |Int |Text |Money |Int |
| |FK_From_ | | | |
| |productid_| | | |
| |products | | | |
+---------+----------+------------+------+------+
One of the user requirements of the OMS is to fill a data grid with product name and the product details which I have the query for or rather I have created a view for, which is then queried from a stored procedure.
CREATE VIEW [dbo].[v_stock]
AS SELECT tab_products.productname, tab_productdetails.description, tab_productdetails.image, tab_productdetails.price, tab_productdetails.stock
FROM tab_productdetails INNER JOIN
tab_products ON tab_productdetails.productid = tab_products.productid
The problem I am having is then returning the data from this query into a data grid, I think the reason is because when I attached the stored procedure to a table and then call that procedure via the table adapter there is a mismatch of the schema - specifically the table it is attached to does not contain the column "productName".
I am thinking I need to create a temporary table to fill the data grid with - however, I am not sure how I would create a temporary table.
Is there something I am missing or not done correctly. As far as I can tell the queries work as when I preview them they produce the expected results.
