I have two tables with one common field. The field is the primary key in one table, and just a plain field in another. When I delete a record in the table where the common field is the primary key, I want to automaticaly delete a record in the other table that has the same data in the common field.
What is the most effecient method of doign this..triggers?
how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.
i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.
there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.
.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?
i want to do it from programatically. i am using sql server 2005
i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.

I am trying to delete a record being displayed in a table on my ManageUser view using a sub-form, thus
<table cellpadding="2" cellspacing="0" border="1" summary="User Grid" style="text-align: left">
<tr style="background-color: #ABC3CB;">
<th align="center">User Name</th>
<th align="center">Approved</th>.....
but instead, it is returning directly to the Admin/ManagerUser view, thus displaying my original set of records again.
I have a table setup in the database for users who are basically going to create a classified listing. How can I setup a diagram that would easily create a table relationship with the Users table, so that it automatically inserts the users username when they submit a new ad? If so, how? I've tried adding a UserName row to my table and creating a relationship with the Users table "UserName" row, but it wasn't accepting the relationship when I tried to save the diagram...apparently because the UserName row in the Users table isn't a primary key?
Also, one this is setup, what's the best way to provide the user a way to see a list of their ads and have the ability to edit them?
I have 2 table Table A, Table B.
Table A - Parent Table
ID - Uniqueidentifier not null(PK)
Table B -Child Table
ID - uniqueidentifier null(FK, TableA)
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
The statement has been terminated.
The insert statement in asp.net is like so:
sqlcommand.parameter.add(New Sqlparameter("ID", Nothing))
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
I have two tables - Student and Advert.

What I want is their student Id to be input into the advert table when this new advert is created. How is this possible?

I have a form that when I click the delete button I want it to refresh the grid with that record removed from the grid. Does anyone know how to do this. Is this something handled in the code behind? Here is my code for the delete button on the design page:
[Code]....
I have a dropdown list, and can select names to delete from db table user.
Just want to add a confirmation dialogue window before deleting the record.
I am using a simple function at js to confirm. Isn't that enough to go to btnDelete_click() if true? I am using LINQ to SQL.
I tried:
(code behind)
protected void Page_Load (object
sender, EventArgs e)
{
if(!IsPostBack)
btnDelete.Attributes.Add("onclick","return check();");
}......
I want to confirm from the user before deleting a record. I want to show a message box to confirm operation... How I do that.. I used query to delete a record on button's click event..
