I have two tables - dt(Mods) and dt(Mods2) - I am trying to create a relationship between them. So dt(mods) has department, category and item columns dt(mods2) has parentDept, Parentcategory and parentItems Now I need add them to a dataset with a relationship key - Something like this but with three cloumns
Dim ParentCol As New DataColumn, ChildCol As New DataColumn
i have master table and it has related record in the child record
there are about four records in the detail table containing master id
how can i get the data group by master id ?? i want a sing row record
suppose:
order 1: item1 : item :2 item 3: item 4 in this shape
is there a SQL statment i could write that would sum each column and allow me to then access each sum individually
i.e
Dim objCmd As New OleDb.OleDbCommand("SELECT SUM(expression) FROM orderForm WHERE OrderDate=@OrderDate", objConn)
is there anything i can replace expression with such that all the columns in orderForm could be summed and returned as one record
or is there a way to replace expression with something that would allow me to just keep changing the paramater so i could continuously reexectute the same command w/o having to create a new command for each column

This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords
FROM (Merchandise)
WHERE Keywords LIKE @term

I've requirement where user can enter multiple columns like first name, lastname, email, age, sex fields and insert them into database.on my frontend aspx page, i'll be showing a single row initially with 5 text boxes(first name, lastname, email, age, sex) and a button to add more columns. when user clicks on add more, another 5 textboxes will be shown and then i'll be taking 5 + 5 (textbox values) and comma seperate them and need to insert into a table with primary auto increment key ID and the remaining 5 columns(firstname, lastname, email, age, sex). I previously worked on the same requirmeent but with only single column. Now i need to insert for 5 columns, How can i do this? Below is my stored proc which i used for single column insertion.

View 4 RepliesI need to know if I've done something wrong, or if the message I'm getting is nothing about which to be alarmed.I'm getting "The relationship '....' has columns that are not part of the key of the table on the primary side of the relation ship which is not supported, the relationship was excluded.
I built four tables, each with one foreign key. I'm assuming I haven't done anything wrong or unusual with my four tables (SQL statements generating the tables are shown below).However, I don't get any lines connecting tables together and all the examples I've seen today seem to have no problem with drawing the connecting lines all over the place.

I have 3 tables User, role and UserInRole THe entity frame work made entities for User and Role and I have successfully made a join with the user and role entities using user.add(role); but I can't seem to get it to remove the link (I want to retain the user and role just remove their association).
using (ProviderEntities context = new ProviderEntities())
{
User u = context.User
.Where(n => n.ApplicationName == application)
.Where(n => n.Username == username).First();
Roles r = context.Roles
.Where(n => n.ApplicationName == application)
.Where(n => n.RoleName == roleName)
.First();
r.User.Remove(u);
context.SaveChanges();
}
The oposite worked when I did r.User.Add(u); but it wont let me now remove it after it been created. Driving me mad as I can't see where I have gone wrong.
