I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).
My existing solution does the following:
1. DeleteAllOnSubmit( Subset of the data from the child table)
2. DeleteAllOnSubmit( Subset of the data from another child table)
3. DeleteAllOnSubmit( Data from the parent table)
4. CommitChanges()
All this resides within a single method, which makes it ugly and not re-usable.
I have considered the following alternatives, but I decided not to use them:
1. Cascade delete on the tables.
2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().
3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.

View 1 RepliesI am having a hard time solving the following with an MVC view. My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from a table called Retailers. I also have another table called RetailerCategories which stores the retailerid from the Retailers table and also a categoryid linking to a Category table. Note that there are multiple records for each retailerid in the RetailerCategories table.
In the view I want to show a list of retailers and with each retailer I want to show the list of categories applicable to them. What would be the best way to accomplish this?

Like I'm having a table with userid and want to get user full name from users table where userId = users.userId
I have a listview that shows the user the details of the members who have sent friendship request. The table from which the data come has two fields namely, sender_id[id of the one who sends friendship request] and receiver_id[id of the one to whom the request is sent].
There will be two columns in the listview. The first would show the pic and the name of the user. The problem is that how am I going to show the pic and the name if the table from where the data come does not contain these info. I know that the sender_id can be used to fetch the pic and name of the sender, but how should it be done?
Earlier I would do something like <%#Eval("fieldName")%>. But in the above described scenario the field is not present in the current table but the other one.

I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
I have a partitioned db where several tables have the exact same structure. I'm able to query the tables using linq, but only by quering the individual tables 1 at a time and by using the explicit table name. For example at the moment, I have 8 tables so I have something similar to the following:
[Code]....
Is there any way, that based on a certain value (stringValue), I could determine which table to query and then code the linq query just once?
I have a couple tables that are kind of unrelated - id like to search through both of them and create a type that i can sift through later
something like this doesnt work

How to do it using SQL ( I am not using StoredProcedure)
Does anyone have some really great tutorials on how to use link with datasets that contain multiple tables that utilise primary key and foreign key relations? For eample
Table1
- id (PK)
- language
Table2
-id (PK)
-programmingword
Table3
-id (PK)
-languages_ID (FK)
-pgrammingword_ID (FK)
-translatedword
Linq search for: Table3.translatedword where Table1.Language ='french' and Table2.programmingword = "yes" does this make sense? im looking for exampes/ tutorials for how to do this? or can anyone recommend any good books on linq?
I am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...
I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)
Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.
I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.
The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.
I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.
All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.
