View 2 RepliesI am using MS Access 2007 as database and VB 2008 to build an application to show the content of 2 tables as a single table.I have two tables in MS Access and i have linked both the tables using "ID" as primary key(1st Table),foreign key(2nd Table). I used Query Wizard to show the data of both tables in a single table(3rd Table).I am able to view the content of all 3 tables using datagridview in vb 2008(Using Code), but i am unable to add,delete,save and search the content of the table using code. My concern is,i will be able to do all these operations using codes only.Would you please help me out in this.

If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.
