I have a SQL Data Source that displays records after going through the Query Builder and select "Test Query" yet when I save it, go back to the design mode and select View in Browser I get nothing but a blank screen.
View 3 RepliesI'm encountering a strange problem. Here is the scenario. I have built a query that accepts a parameter (WHERE LIKE clause).
I've tested this within the query builder and it returns exactly the number I would expect.
I then go back to my webpage and add the following controls:
Dropdown
Gridview
the user to make a selection from the dropdown. Postback on the dropdown is enabled so the page reloads and the Gridview displays the filtered results (via an objectdatasource). I've set the parameter to the dropdown control.
The trouble is when I run the page I make the selection in the dropdown no results are displayed. Even though the text displayed in the dropdown control is exactly the same as I inputted into the query builder when testing it.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.
I have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.

Can anyone offer any thoughts on how I should construct the query to perform this?
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 need to write a query as follows which will be bound to a grid

I'm using Visual Studio 2008 Query Builder and am trying to pass a value to a parameter that uses the IN OPERATOR.Here is my sql from qb:
SELECT COURSE_TITLE, INSTR_NAME, ADMIN_UNIT
FROM vwHRIC_EC_ContractSummary
WHERE (ADMIN_UNIT IN (@ADMIN_UNIT))
The trouble I am having is that if the parameter @ADMIN_UNIT contains more than one value such as (8X, CV) that the query doesn't return any data. If I run the same query with only one value such as (8X) it works fine.I have tried different formats like (8X, CV), ('8X', 'CV'), (8X; CV) but none have worked.I ran this same query in SQL Server Management Studio and and it returns data no problem but can't get it to work in Query Builder for my aspx application.Does anyone have any experience with this problem and how did you correct it?
I am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?
I have a gridview that has a sqldatasource for it's data and it works well. I also have four dropdown lists that I need to have filter the data in the grid if they have a value selected. Here's my query:
[Code]....
What I need is if a user selects an Asset_Tag from a dropdown list the gridview should requery with the Asset_Tag as a parameter so only that record gets called up. Is there a way to do this in the selected indexchanged event? The same would hold true for the other DDLs. It seems like if I assigne the datasourse programmatically I lose the builtin sorting ability which isn't acceptible for this application.
i use this query as my sql query :
SELECT TOP 5 * FROM MyTableName WHERE ID=@ID ORDER BY NEWID()
As you may know it gets 5 records by random. I use it with dataset and bind the listview to this dataset and in ItemDataBound i want to do some programming (like making some controls visible or invisible) i need itemindex.
but the question is : how can i get the itemindex of a listview when sql query selects records randomly?
i create view in sql server and execute a select query using AND operator on it using vb.net and bind data with gridview...but i am not getting result in grid
View 3 RepliesI am writing a linq query to select a blogpost,
[code]....
The blogpost i am testing got 3 tags attached to it. The table structure is:
(table)BlogPost -> (table)BlogPostTags <- (table)Tags
So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.
When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
How can I SELECT second if first SELECT returns nothing?

I need to know how can I select a gridview row based on a query string data. In my case, the query string will contain the id that exist in the Table related to that grid. Is there a way to do this from the code behind? In other words, if I click a link with that specific query string, can I open the page and tell my grid to select a specific row based on the table row id?

My issue is that I am pulled three tables together using the Query Builder and I only want to show data where a specific date is greater than todays date. Here is what i have so far:

Where it says '2010-09-01 00:00:00' I want that to be the todays date.
Is this possible?
I have two tables. One table containing 1 master record and the other table containing multiple records per 1 master record. I want to only display in a gridview (or whatever is best) the master record AND its assocated detail records IF certain fields in the detail records are there. I have been trying to figure out how to do this but I am still a bit of a newbie and I don't how I can do this.
