I have two tables: One wich contains the columns "first_name", "last_name" and "status_id". The other table contains "status_id" and "description".
Now, I want to display "first_name", "last_name" and "description" in one DataGridView. What is the best way to do this?
What I'm doing now, is that I'm manually adding a datacolumn to the first table. Then I'm looping through each row and filling the new column manually. Now, that doesn't seem very smart and efficient, but I haven't found any better solution.
customers
phonenumbers
customers_has_phonenumbers
customers -> detailed
customers.customer_id int(11) primary auto_increment
[Code] .....
How to get the data by customers.customer_id from phonenumbers?

I have two relational tables: the Profiles table which contains 3 kinds of user roles (Manager, Developer, Common User) and the Users table which contains information about the user and their roles ID (Profile_ID field) in the Access 2010 database.
I created a Webform in ASP.NET which should simply register users, asking for their names, selecting their roles in a dropdown list and inserting it all in the Access database. As in the following code:
Dim cs As String = ConfigurationManager.ConnectionStrings("Access 2010").ConnectionString
Dim cn As New OleDbConnection(cs)
[Code].....
It happens that I can't insert in the database because they have a relationship between each other, it gives me an error. Actually, I just need to insert data in the Users table 'cause the roles are fixed. How can I do it?
EDIT
The error I get is You can not add or change records, it is necessary that they have a related record in table 'Profiles'.

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()

View 3 RepliesWe are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.
I have a 5 tables in my database and i want to access all my tables togather at a time.e.g.I have a code for one table i.e. rs.Open "select * from Group_info", con, adOpenDynamic, adLockBatchOptimistic. instead of Group_info table i want to access 5 tables also as Login_table,User_info table,group_name table etc. How i do that

The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too.

When i set a breakpoint on the "Private Sub Gen.." line, and step through the code line by line, it inserts a new column for each variable declared, so in this case it will insert two columns before it even hits the "If MyBooleanValue()..." line (I can watch it actually happen due to the Excel app being visible). However, if i dont set a breakpoint and just let the code run straight through this doesnt happen.There is no multi threading happening or anything else that i suspect would have any impact on the code.

I am writing an application in which we have a Product Module, Now instead of defining individual products, we want to just state the Size Ranges in Width, height and different size scale available, and then automatically generate a list of products with all the Size combinations. I cant figure how to do this.Ill give an example.This is how we define a product

If i had a fixed number of Size types i would just run For loops within for loops and inside the inner most for loop write an Add Item statement with Index of evry selected item, however since the Size types are dynamic, i need to write a recursive loop, and i just cant figure how to.
