Search db by Field
http://www.codeave.com/asp/code.asp?u_log=102
Providing search capabilities to a db enables users to query on whichever element you target them to. However allowing users to target which portion of the db they would like to query gives extra value. In this example, utilizing our db of US States (state, statename, and capital) the user can search in any of three fields (by dropdown menu input) rather than the application targeting one specific table element. Note: The db only has 50 observations in it, so it is better to search on single or double letter combinations.

But why? I read Part I and I was able to implement a simple database program very easily. Why would I need to learn anything more?
You might have implemented some database program.. but I am sure it would be a very simple one. You may even be able to implement a good database program without Joins. But you wouldn't be using the features of SQL that let you do the same work much easily. Without Joins, you may manage SQL.. but with Joins you could do things very easily

Allowing multiple choices of data elements enables people to customize views of your data and adds value to your applications. The following example utilizes our db on the career statistics of Hammerin? Hank Greenberg. The year and team he played with are already part of the sql request to the db. User inputted choice(s) are added to the basic sql statement to draw them from the db. Since the input from the dropdown menu comes through comma delimited it is simply written into the statement without modification. Two simple for next loops determine which elements are part of the record set and displays them accordingly.
