This will return only one row as ID is uniquethen I have a procedure that gets all the colors that are available for this model number and i use that data in a drop down list, it is like this

[Code]....

this can return multiple rows with different colors.Right now i am opening a connection getting the product data, consuming that to properties of a class, then to get the data from the Colors I open another connection run the procedure with the model parameter being the model returned from the first sproc and bind that to my ddl.I want to do this in one connection and just get two result sets back. So how do I set the parameter of the second procedure to be the model from the first?

DataSource Controls :: Combining Two Queries - Count For Each City As Whole

Feb 4, 2010

I know there has to be a way to do this but for some reason I keep getting it wrong. I have one query which pulls all of the cities from a zipcode database like so:

[Code]....

Then I have another which counts the records from a transactions table per city, like so:

[Code]....

Only the zipcode is stored in the transactions table, so the idea here is to get a list off all the distinct cities that reside in the state. Once I have the cities, I want a count for each city as a whole, so I need to go back in and get all of the zipcodes that make up one city, and then count the transactions for those zipcodes. It works using the first query above, looping through them and then executing the second for every pass. But shouldn't there be a way to do it all in one query?

DataSource Controls :: Accessing Specific Column In Database With Column ID With Table Adaptor

Jan 6, 2010

I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.

The current code:

[Code]....

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?

Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

DataSource Controls :: SqlDataSource With A Lot Of Parameters?

Sep 4, 2010

I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied

SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender

I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.

DataSource Controls :: Using Parameters For A Listview

Jun 4, 2010

I have webform with a listview control on it that uses 2 date values supplied by the user (via 2 text boxes) to dynamically set date range parameters for the datasource. The user enters two dates and clicks a button that runs the following code that sets the parameters:

[Code]....

This code works the first time the user clicks the button. But if they change the date values and try again, it only returns the result set from the first request. The parameters are not updated to the new values supplied by the user.

DataSource Controls :: Can Use If Else In Sqldatasource If Else Parameters

Oct 4, 2010

I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.

On my SqlDataSource my InsertCommand looks like this:

InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"

This works as expected: If the username is unique, the row is created.

If the username already exists, the row is not added.

The problem is, if the row already exists, the insert is rejected but the user is not notified.

So my question is, is there a way I can notify the user?

Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.

DataSource Controls :: Setting Parameters In ListView

Mar 17, 2010

I have a ListView that, among other things, in the EditItemTemplate, has a pair of related DropDownList controls, sort of a parent/child relationship. The selected value of the parent is used as a parameter for the SQL Datasource of the child. Outside of a control such as the ListView, this would be easy and I'd simply set up a ControlParameter for the SQL Datasource and life would be good. Within the DataList things are not quite so simple. My plan is to set the parameter of the child in the Selecting handler of its datasource. I have hard coded some values and this works the way I want it to. My problem is getting the "parent" value. I've got two theories on how to get this:

#1, I've tried instantiating the parent DropDownList but it is either not available at this point in the page life cycle or I just don't know the syntax to get at it from within the Selecting handler.

#2, I'm thinking I may have to grab the value from the underlying data for the ListViewRow that I am editing, but again, I do not know the object model well enough to get at those values.

Below is a code sample for option #1. As stated, setting the parameter works, but getting the value of the DropDownList does not.

[Code]....

Ive passed in '02/06/2010' as the date, in the database, the Startdate column has several values of '2010-06-02 13:08:50.503' so I guess its not being found because of the time part. Whats the best way to make sure that I retrieve the correct data ? Im not concerned about the time at all, I just need all rows for 02/06/2010.

DataSource Controls :: Using Table-valued Parameters?

May 19, 2010

This is my first attempt in using table valued parameters in my stored procedures. Please find the scripts down below. The idea is very simple. I'm trying to insert a new product into Products table and if the product has attributes, I'll insert them into ProductAttributes table which is where I use table-values parameters.

I was able to test the stored procedure manually. It's working fine. So the error must be in the C# code but there's not much to it.

Here's the DAL code in C# that calls the stored procedure:

[Code]....

Just in case you need it, here's what my Product object looks like:

[Code]....
And the ProductAttribute object is even simpler:

Here's the SQL scripts to create the tables, stored procedure and user defined table type:
