How SQL TABLESAMPLE Actually Picks Its Rows
Original: Tablesample Picks Rows
A new article on Boring SQL examines TABLESAMPLE, the SQL clause that samples rows from large tables, and explains how databases actually choose which rows are returned. The piece walks through the semantics that often surprise developers, since results are not truly random and behave differently across database engines. Readers on Hacker News are discussing the nuances and practical implications for analytics queries.
Why now: Technical articles that demystify little-understood SQL clauses regularly spark discussion among developers on Hacker News.
