I have been working with this database for some time. Here is the situation...
I inherited a MS SQL database that has hundreds of tables with similar data. For instance:
FordTampa_customer is a table,
ChevyAtlanta_customer is a table, etc....
All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...
So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.
All right, on to the real point of my post...
Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.
I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:
[Code]....
I am not sure how to take those names from the table and do another select based on that list of names.
I have a SQL Datasource populating a Drop Down List with Company Names. The Select Statement the Datasource uses selects Company ID and Company Name.When a company is selected from the list, there is a button on the page to continue processing with the selected company. On the press of the button, I want to set a session variable for the Company ID of the Company selected. This Company ID is obviously held in the Datasouce. Any idea how I get at the Company ID.My code will look like the following:Session.AddsessCompanyID", ????????????)where ?????????? represents the source of the Company ID.

I have 3 drop down boxes, created using the HTML select tag. On page load, the first box has a few names. Now, when I click on one of the names in the first box, some more names should appear in the second and when I click on a name in the second box, some more names should appear in the third box. How can I achieve this using AJAX? I have to use ASP.Net and MS SQL Server only. I'm a complete noob to AJAX and I've been educating myself about it, but nothing's working out. I've been looking for the code for close to a week. I looked up w3schools.com, but when I tried that code, it didn't work. Please help me out and please tell me step by step, the things required in order to make it work, and what goes where. I have a deadline that is fast approaching and am at my wit's end trying to make it work.

I have a stored procedure which returns a table. The stored proc is called via a linq datacontext.
It works fine and I get the table back however I really want to also get the title relating to each particular cell returned.
The stored procedure call is like:
var table = DataContext.GetTable().ToList();
So I get a List<GetTable>. The data is fine I just want the column names as well.

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?
i have a small app. the database has two tables. Category(CategoryId, Category), Quote(Id, CategoryId, Quote) these two tables are related via FK (CategoryId). In my page i have a simple drop down list, button and lable. user selects a value from drop down list like 'politics', 'comedy', 'famous' etc and then they hit the generate quote which should fetch a quote from the quotes table by passing a value like 'politics'.
however, i need to pass an int value (ID) from my drop down since that is the value which will fetch corresponding quote using my SP but (1) how do i pass a drop down value's ID and (2) is the SP below correctly done?
SP code:
ALTER PROCEDURE [dbo].[GetQuote] (@CategoryId VARCHAR(2))

This may or may not be possible but I'm trying my best to find out, I'm a complete novice when it comes to ASP.At the moment I have drafted a basic html page. This page contains a drop down list and several tables all hidden by javascript and then displayed based on the drop down selection (onchange event)I'm trying to convert this into an asp page so that I can dynamically populate the drop down from a table (this will be a list of names)and then based on the drop down selection (onchange does not necessarily have to be used, could maybe use a submit button) will populate a table below the input box with all the information for that name, in many cases this would be multiple rows.
View 3 Repliesis it possible for reorder list to to allow user to drag n drop via column cell.
For example,
Column1 | Column2
------------------------------
Value1 |Value5
Value2 |Value6
Value3 |Value7
Value4 |Value8
Value 1 was drag n drop to the position of Value5. And Value5 ,Value6,Value7,Value8 position are reorder like Reorderlist in row.
Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.
So my drop down list looks like;

And then I have setup a datasource (even though I may get rid of it to bind in the code behind file)

I have a datagrid that populates correctly and a drop down list.
I have a table with (below) and it popluates a drop down and works properly.
UploadFile -- UploadFileTypeID
-Select 0
Images 1
Spreadsheets 2
Documents 3
Inside the datagrid sort command I want an IF statement. But the IF statement I have now doesn't recoginze whats inside the SQL table ( == "Images").
I have this...
[Code]....
From my understanding this if (ddl_Upload.SelectedValue == .... Is only recognized if I would have listed -Select, Images etc as List Items for the drop down???
I know there is a way to get all the column name from a table, but that is not what I want
I want to get only a few column name from the table, is there a way to do this?
Let say, table A has three columns that is A1, A2 and A3, I only want A1 and A2 column names, again, can this be done?
BY the way, I am using SQL Server 2005 with asp.net application.
