I have just been working on a new course and needed to select a random record from a database table. I thought it would be useful to write this tutorial for anyone who was wondering how this can be achieved.
The actual code is really straightforward and uses the RAND() function as follows:
Lines 1 & 2: we are selecting all fields from the table
Lines 3 & 4: we specify the table from which we wish to retrieve the data
Lines 5 & 6: we specify that we want a random ordering of records
Line 7: we limit the returned data set to 1 record
It’s as easy as that!
