Read from database line by line

For a project work at school I need to make a VI which reads text from a database.
I'm currently able to read from it and save it all at once in an array.
But the task is to read the database line by line, depending on a random number which I generate.
This random number will be the number of the row in the database in microsoft access.
Does anyone know how to do this? Or better, have a VI which does what I want?

Thank you in advance.

This VI reads the database all at once and writes all the lines immediately into an array
