I want to write a sql to delete the currrent select parent and well as all child record, how can I do that?
I have a table that needs sorting by its hierarchial structure of parent-child.
An example of my table is below
ID Name Parent ID Sort Order 1 iPhone Dev 0 1 2 iPhone Lounge 0 2 3 Web Development 0 3 17 Javascript 3 1 24 CSS 3 2 25 prototypes 17 1
As you can see above, my table structure follows this pattern
[Code]....
My overall aim is to have the sql order the table for me, and by using this new "depth" column, I will be able to indent by categories in the menu on the front end, you have probably seen this before, but all the tutorials I have read dont really explain it very well, or assume you are sql savvy.
ID Code Name 1 abc a 2 abc Null 3 def b 4 def Null 5 xyz Null 6 xyz Null
I nned to get all record from the code table and against each code I have to get all the rows from the details table, if some code have value their need value and if not then Null
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
I am just getting started with entity framework with asp.net 3.5 using VS 2008
There are two tables, Categories & Subcategories:
Category table: CID, CategoryName Sub Category table: SID, CID, SubCategoryName I would like to get SID, CID, CategoryName, SubCategoryName in the gridview. Just as we write a select statement i.eSelect a.sid, b.cid, b.categoryname, b.subcategoryname from subcategories a inner join categories b on a.cid=b.cid & put the same in a gridview.
I was trying for the whole day & couldnt get atleast one url that would teach how to do it.
Is there a way to create a contact form that takes the name. address and other info for the master record; Then, somehow, on the same page, allow the user to enter multiple contact info as chid records (i.e. phone, email, etc.)
All this using the Objec DataSource or SQL DataSource (which ever is easy) and doesn't require writing too much code.
I'm a having a problem in passing the value of a variable from child package to the parent package in SSIS. either using configurations or using scripting (c# or vb.net)..
I have one table named 'dbo.ac_Products' Within this table there is a column named 'ProductId' There is also another table named 'dbo.ac_CatalogNodes' Within this table there is a column named 'CatalogNodeId' and a column named 'CatalogNodeType'
I need to delete all the rows from 'dbo.ac_Products' and 'dbo.ac_CatalogNodes' where 'ProductId' = 'CatalogNodeId' and 'CatalogNodeType' = 1
In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.
I have a parent page with two data controls. I want to be able to open a child window, do something on it, and when it closes I want to rebind only one of the two data controls on the parent page. I have the control I want to update within an UpdatePanel so would like to call rebind it and call UpdatePanel.Update().
I am deploying the solution on the server i want no user can deleted the table by using the sql injection, i want to put restriction on the table that no one can delete the table. in short drop table should not execute.
Colour(Colour ID, Colour) DogColours(ColourID, Dog ID) Dog(Dog ID, Breed)
Colour ID and Dog are primary keys.
I have three web forms, one for each table. Dog colours consists of data that is already in the system from the other two tables. It basically joins a breed to a colour. My problem is this:
When i try delete a dog which is being used in dog colours the program crashes. How can i prevent this crash?
The second problem, the data source in the dog colours web form has the insert, update and delete tick boxes greyed out in the 'configure the select statement' so i am unable to delete a colour and dog joined together. how can i delete something in the dog colours?
a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2 Thus representing a simple "1 to many" or "parent/child" relationship in the database!
SqlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).
SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.
HOWEVER - THE PROBLEM ARISES...
The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctly SqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.
I've tried setting the SqlDataSource2 parameters to:
My code is not updating the sql database. I am definately passing the correct information in to this function, and it runs without errors. If I exec the procedure with the passed in data, it works great. Can someone tell me what is missing?
How do I remove duplicate rows from a data table based upon a two column values;I want to pass in a Data Table and a column names and get the data table back with data rows where that columns value are unique.
I have a Data Table with Duplicate Rows i want to delete the duplicates rows based upon two column values if both columns values are there then Delete the row.
I've have to delete multiple rows from database in a table . Which is the best way to delete data to optimize performance of sql server as well as asp.net.
