I have three tables:
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?

View 5 RepliesNot a fan of creation and modifcation data in each table's row but I don't make the rules here. Something about normal comes to mind. Simple method to insert or update data in a table ia EF. Datatype = smalldatetime and no it is not changing across schema. Don't care about milli seconds. In oOrg = null I always fail because of a datatype mismatch.Not sure but didn't M$ make both of these products, and shouldn't the EF know about a smalldatetime when it reads the schema? So what is the fix outside of changing many tables to be datetime which is frowned upon at this piont.

View 2 RepliesI attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :

So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.
SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))

View 7 Repliesusing VWDExpress2010, is there a way to print the table definition for an SQL table that has been created within the designer? I would like to begin using SQL databases for more of my projects but find the difficulty in working with the tables (compared to other options) to be such a pain that I usually choose some of the other formats. Typical problems are simply documenting the structure, moving data in and out with some form of command line feature, etc.
View 2 RepliesOn runtime I am creating table structure using javascript and appending it to the div which is placed in an update panel. Problem here is, when I use asp.net button control, onClick of the button it posts the page to server and whatever javascript tables I have created it goes off. When I use html input button (input type="button") I don't face this problem and tables also stay there. But I have to use asp.net button to take necessary actions on the server side. Is there any way that I can restore the structure or use asp.net button control alongwith dynamic javascript.
View 1 RepliesI am trying to create a TreeView nested structure with the use of self referencing table fields. Here is a simple example:
Category 1
Product 1
Toy 1
Toy 2
Product 2
Toy 3
Toy 4
more categories.. The database table has a single table called "Category". The ParentCategoryId points to the Category which is the parent. So, for the Category 1 the ParentCategoryId is null since it is parent. For Product 1 the ParentCategoryId is that of the Category 1 id and for Toy 1 the ParentCategoryId is that for the Product 1 id.
I am using the following code but it does not generate the TreeView (ASP.NET) successfully.
public void BuildTree(List<Category> categories, TreeNode treeNode)

if (treeNode == null) return;[code].....
I have this table structure, and I can pull ot all I want like product details, color, size and so on. Now I want it to work like this. When I select a color only sizes avalible in that color should be returned from the database, and same thing when I select a size only colors avalible for that size should be returned. NOw it works like price and quantity sets to zero, but it should have been better if it was impossible to choose a combination that don't exists.
Then I have one more. SizeId and ColorId can be null in db. That is not good when I try to receive those rows.

View 1 RepliesIn my form there are about 6 parameters and two of them have multiple values, upto 6. I'm imposed by the restrictions that I can't change the table structure. The table have 8 fields one for ID as primary key, one for foreign key and other to store data. The two fields which have multiple values are color and size. A size may have different colors and vice versa.
The programmer which have developed the site earlier used a stored procedure to store the data in database. And he implemented the above scenario one by one for each color/size. Now I have to put all in one.
How can I do this. As I can't change the table structure at current moment as this will disturb the whole E-commerce site.

I have two tables - Student and Advert.
I want to do the following;

2. StudentID is primary key for that table, it is a foreign key for table Advert
3. When student is logged in, they create 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?
