# Snowflake ASOF JOIN in 7 Minutes | New SQL JOIN

**[techTFQ](https://daily.dev/sources/techtfq)** · 7 min read · 0 upvotes · 0 comments

## Summary

ASOF JOIN is a SQL join type supported in Snowflake that handles time series and event-driven data by matching rows on timestamp fields using exact or nearest-preceding/following values. Using a trading platform example with trades and quotes tables, the tutorial demonstrates how ASOF JOIN solves the problem of joining records where timestamps don't exactly align — finding the most recent market price in effect at the moment each trade was executed. The syntax uses a standard ON clause for equality conditions plus a MATCH_CONDITION clause for the timestamp comparison.
