Date Range Search with BETWEEN
This lesson covers date range searches with BETWEEN, so you can retrieve data that falls within a specific period. It's for anyone searching "SQL BETWEEN tutorial" or "SQL date range search."
Using column BETWEEN start AND end on a date column retrieves everything that falls "within a given period" — a common need for filters like "only this month's orders."
The example uses event_date BETWEEN '2026-01-01' AND '2026-12-31' to fetch only events happening within 2026. Even dates stored as plain text work correctly with this kind of range comparison, as long as they follow the YYYY-MM-DD format.
A common early mistake is misjudging the boundaries — BETWEEN is inclusive of both the start and end values, so keep in mind "whether that exact day counts" or the result can end up subtly off from what you intended. This general-purpose operator works on numbers too, but date range searches specifically are an extremely common, high-value technique in business systems.
