DataSource Controls :: Take Names From The Table And Do Another Select Based On That List Of Names?
Jun 1, 2010
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 am trying to populate table column names into a dropdown list . how can I query using Linq to SQL to just get the list of few Column names ? in a method in DAL which I can use to load in my UI page !!
I have a table that has three fields that hold the ID for vendors.They are vendor1, vendor2, and vendor3.These link to my vendor table on the ID.I want to select all three vendor names from the vendor table. when i do the following, it returns nothing
i seem to have a problem with my gridview, i have a gridview with a list of names, this gridview is assign to a datasource and the datasource already has a select statement to display a list of names to my gridview, and i have a search dialog which i use to filter data to be displayed on my gridview, my problem iS after filtering , when a user select a certain row the gridview refreshes and display the initial data(it binds again the use the default setted select query). On my search i use
to filter the grid according to my search criteria, which is the one i have assigned its select to the string varieble filterQuery.
That works fine, and dispaly only d data i setted my search to retrieve, bt my problem is when a user select a row on d gridview , d gridview is repopulated with d initial data(Use initially datasource select statment). How to make d grid to stick to d select statement that i setted on my search and not letting it to go back to the initial setted select.
populating the dropdownlist with column name. I have a gridview that has 7 columns . I want to have a textbox search and dropdownfield where user can select column name and type a word in search box and click search so that text for that column name is being search and displayed in grid. how I can fetch just column names from DB and search ?
I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.
The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.
I would like to do this in the web.config so we could add/remove columns without having to redeploy.
For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.
I have a mssql table of names. This table contains names from A thru Z. However, I want to be able to display names by their beginning alphabet...Like first Display names A thru CThen Display Names D thru F and ..so on....and so forth....thru ZI using asp.net and have a grid view with paging enabled.....
I am writting a custom class with which I manipulate the data for my website. I was wondering if there is a way to connect to a database and retreive the column names for a given table with out sellecting any data in the table.
Currently I am using an sql select and connection string to create an SqlComman object. Then I use the command object to create a SqlDataAdapter object which I use to fill a DataSet. At the end of all that I am able to retrieve the column names but I have select data and retreived data.
I need to get two fields from a database table (retrieved using linq-to-sql), one field is a datetime (and is a fixed field) and the other is always a decimal, but the field can be different.
The table holds currency data which is processed twice a day and in different currencies so could have fields such as AM_USD, PM_USD, AM_EUR etc. And I need to get data such as a list of the date against PM_USD or the date against AM_EUR.
I would like to be able to call the data using a lambda expression for example (this is a stripped out example):
data = TableData.Select(x=>new {x.DateTimeAdded, x.[**field name as string**]});
I have been trying to write a function to do this, and am failing dismally.
Is there a good way to change the aspnet_Users, aspnet_Membership, aspnet_Applications and other table names which are generated by the ASPNET SQL Server registration tool -
[URL]
and change the reference to them in web.config or machine.config without breaking the default login, profiles and roles functionality that is provided by those tables?
Here is what I am basically trying to accomplish I want to upload images to the server separated into categories and save the file path into the database. I have found plenty of documentation on saving to a file and the file path to a database. But, I haven't found anything that will allow me to seperate the images into categoies.
I have made three tables in the database
[code]....
What I am trying to do is create a gallery for our clients to browse and download different vesions of posters and ad cards.
I have a Webform with a large number of user controls on it, they were auto generated as part of a formview.
I would like a way (Add in etc) to print a list of all of the names of the controls for me to use for the code, rather than having to go through and write them all down.
does anyone know of an add in or an easy way to do this in VS2010..?
