Following example, extracts all of the records in a database table and stores into a 2-dimensional array. This gives you an advantages to modify and work on data.
In this article we will learn on how to use database transactions in ASP. This will allow us to execute all database queries or none at all. How many times have you wanted to insert, update a lot of records collectively wanting that either all of them get executed or if there is an error then none is executed at all ? Well, if you haven't this need yet, you will have it in near future.

The DSN connection requires that you register the DSN for the db prior to executing the code. (Note: G.I.G.O Garbage In Garbage Out applies here, be certain all table elements entered appear in your db. Table elements must be entered in the select field * will not work here.)
