Its possible with out setting primary key also. but you should have a unique value column in the table.

You need to find the row that matches the one that the user selected to delete. Use the SQL "WHERE" Clause to help you with this.

For example, if a First Name, Middle Name and Last Name makes a unique key to identify someone you could have something like:
Expand|Select|Wrap|Line Numbers
  1. DELETE FROM Persons
  2. WHERE FirstName='John' 
  3.       AND MiddleName='Jayne'
  4.       AND LastName='Doe' 
You may need to use more than 3 fields to ensure that you are deleting the right record...this is why unique identifiers are easier to use (as veenna suggested)
