Get random rows from a table in SQL Server

Antonios Chatzipavlis
Monday 13 September 2021

Υπάρχουν περιπτώσεις που θέλουμε από ένα πίνακα να πάρουμε τυχαία κάποιες εγγραφές για να υλοποιήσουμε κάποια σενάρια ανάλυσης. Υπάρχουν κάποιες functions όπως η RAND αλλά δεν καλύπτει πάντα σωστά την ανάγκη αυτή. Ο ασφαλέστερος τρόπος που έχω βρει μέχρι τώρα καθώς κάθε φορά επιστρέφει διαφορετικό αποτέλεσμα είναι να εκτελέσουμε ένα query όπως παρακάτω στο πίνακα που μας ενδιαφέρει.

select top(10) * from schema.table order by NEWID();
