For the purpose of this tutorial, we will use a database with one table for an example. The database will be listed in the left hand window, which is blue, with the table listed below it. The right hand window is where all the activity will take place.
Let's get started on deleting fields from database tables. Begin by selecting the table(from the left hand window) that you wish to delete fields from, and clicking on it. That will bring up all the details about the table in the right hand window. You will see a list, in chart form, of the fields contained in the table. Find the field you wish to delete. In front of the field name, there is a check box. Mark this box. Then below the list you will find the Delete Icon. It is a big red X. Click on it. A screen will ask you to confirm that you really want to delete (or Drop) the Field? Click Yes to confirm. Now the window will show the list of table fields, and the deleted field is gone. A message also confirms that your action was successful.
