DataSource Controls :: How To Select All Vendor Names From The Vendor Table
Jan 19, 2010
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 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 new to web forms programming, I have read a book on html and css and I understand enough to be dangerous. I have a form with with a main <div> and using a css style sheet and an ID I have it set to position: relative. Within that div I have a second <div> set to position: absolute. The I placed it where I wanted it and added a gridview. The GridView has a commandfied with a view button. When the button is clicked a panel appears below and display's form data. Note: the Panel is wrapped in an UpdatePanel Where the trigger is the command button in the grid above.
In the panel I have a <table> that is 4X10 I have it layed out where there is text to the left and the a label in the cell next to it. That seems to look ok. Here's a link to the html source [URL] What I cann't figure out is how to get the three vendor labels to be layed out in a horizontal line. I would like them to be displayed spaced apart. I could provide a layout via a pdf if anyone wanted to see it?
Our internal HR application is developed by the vendor, but I've been given a requirement to change the behaviour of a certain piece of functionality without their assistance (which I don't want to do, but am investigating...). The functionality in question is an .ashx page which does a number of database lookups, and is called via javascript functions on a web page. We want to add one further database lookup.
We have control over the javascript code, so that's not a problem, but the code for the .ashx page is held in a compiled assembly. I've found where it is, and looked into it using .Net Reflector. Reimplementing the methods involved wouldn't be difficult, if it were technically feasible.
Can I create a new assembly, paste the source taken using Reflector into it, make my modifications, add the DLL to the application, and then set up a new .ashx to refer to it?
The bits I'm worried about not being possible are:
The code refers to some vendor classes held in other assemblies; can I just add references to those assemblies in Visual Studio to allow it to compile, and then when it's compiled and put on the server it'll all work?
Will I have trouble getting the web application to accept the new DLL, given that generally this application is not something we make changes to ourselves?
EDIT:
Some clarification: I'm not actually planning to replace the vendor's DLL with one of my own, that does sound like going a bit too far. Instead, I would make a new DLL with just the one function in it I need (based on stuff taken from the existing DLL using Reflector). I'd need that code to reference other utility vendor code so that it can get at classes needed to access the framework. I'd make a brand new .ashx page to serve up the code in the new DLL.
Luckily after all this I'm off the hook, because my customer agrees that things aren't desperate enough for us to attempt all this!
I have an extranet site (asp.net), we want that if an employee click on the link, it will automatically get them in. But if an external user does it, they will be redirected to a login page.
is it possible? how to know if a request come from internal user (employee) or external user (vendor).
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 to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
I need to select a field value from a database table. If the value read is '1' then I need a 'Y' to display as output in the select statement. I haven't figured out how to do this yet and queries I tried that did not work.
select IsIata from Table_1 CASE WHEN (IsIata = '1') THEN 'Y' select IsIata CASE WHEN (IsIata = '1') THEN 'Y' from Table_1
I need to display the table name in the select statement. how?
exact question:
we have common columns in two tables. we are displaying the records by using
select column_name from table_name_1 union select column_name from table_name_2
But the requirement is, we need to display the source table_name along with the data. consider a,c are present in table_1 and b,d are present in table_2. we need the output in the following way
eg: column_name table_name a table_1 b table_2 c table_1 d table_2
I am using a CustomSiteMapProvider to draw the SiteMap from a MS SQL database table. If I select all the rows in the SiteMap, everything works correctly. I now want to select a subsite from the SiteMap and display it and this subsite's subsites only. I am using recursive SQL to do this. The code below works correctly except the root record, record number 286, is not included in the result:
[Code]....
How do I include the root record, record ID 286, in the result?
I have set up Linq to sql. I now need to fill a formview with a select that does a join across a few tables. Have not been able to find any example or tuts that go beyond the simple select. Any suggestions? Can this even be done?
I need to display a single field from an sqlserver table, do I need to use sqlDataSource ect. or is there a simpler way (like msaccess's LookUp) for single values.
I would like to Select all entries in the GalleryAlbums table, but Order them (DESC) by date values in a column (upload_date) on the GalleryPhotos table. Both tables have a column "album_id"
A little confused how I might write this statement.

I'm implementing a BLL layer and have a few questions. First, in my DAL, there is a contacts table, the select method is a sql query against a sql server 2000 database. The preview data returns everyting as expected. The query is
[Code]....
The BLL method is built like so
[Code]....
When using the BLL method to a gridview, the results of the subquery are not displayed. There are also other methods, each having a different where clause for ContactRole_ID and each is having the same issue of not displaying the subquery reult in the gridview. No error, but no data is displayed for the subquery either. Here is the templatefield of the gridview
[Code]....
Another item that is causing an error is in trying to update a record. Here is the DAL update method
[Code]....
And the BLL update method
[Code]....
The error says i have extra parameters, but have no clue where the extra parameters are being picked up. The error isObjectDataSource 'odsContacts' could not find a non-generic method 'UpdateContact' that has parameters: _ContactID, _Active, _ContactName, _Office, _VirtualOffice, _Pager, _Fax, _Home, _Cellular, _Email, _ContactRole_ID, Active, ContactRole_ID, ContactName, Office, Email, VirtualOffice, Pager, FAX, Home, Cellular.And the objectdatasource
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
