I have a database from which the data is taken for the script, how to make that the lines are taken not in order, but randomly and at the same time do not repeat?
There are many solutions to do this, but which solution helps to optimize the source code is important. Please clarify the purpose, explain more clearly
This can be done when i am using remote database but is it possible to apply in local database ? i want to prevent duplicate entry in database .
Only with a filter on the content of the data in the table.
