Comments - Data Sampling: Techniques for Efficiently Finding a Random Row

3 years, 11 months ago Darcey Lloyd

1. Get no' of rows in table 2. Gen rand number(s) between 1 and no of rows (no duplicates) 3. Return row(s)

No sorting should be required, why would that even be an idea? Amazing that these are still the solutions in use... Should have been internal feature long ago.

Just add SELECTRAND * FROM xyz WHERE x = y LIMIT 10 etc
