DATE_TRUNC in Snowflake - Examples & AI Generator

DATE_TRUNC in Snowflake is a versatile function for rounding date, time, or timestamp fields to a specified part (such as month, week, or hour). However, Snowflake's SQL syntax sometimes differs from other databases, creating a learning curve for SQL developers and analysts. Instead of searching for correct clause order or the right truncation part, you can use AI2sql to generate production-ready DATE_TRUNC queries in seconds—no coding or memorization needed.

DATE_TRUNC Syntax in Snowflake

Basic Syntax

DATE_TRUNC(<date_or_time_part>, <date_or_time_expr>

• <date_or_time_part>: String specifying the part to truncate to (e.g., 'MONTH', 'WEEK').

• <date_or_time_expr>: The date, time, or timestamp column or expression.

Note: Snowflake uses single quotes for the part, and accepts various granularity levels (e.g., YEAR, MONTH, DAY).

DATE_TRUNC Examples You Can Generate Instantly

1. Monthly Sales Aggregation

SELECT DATE_TRUNC('MONTH', order_date) AS month_start,
       SUM(order_total) AS total_sales
FROM orders
GROUP BY month_start
ORDER BY month_start;

Business use: Calculate total sales per month for financial reporting.

2. Weekly Active Users

SELECT DATE_TRUNC('WEEK', signup_timestamp) AS week_start,
       COUNT(DISTINCT customer_id) AS new_users
FROM customers
GROUP BY week_start
ORDER BY week_start;

Business use: Track new user signups per week to measure growth.

3. Hourly Order Counts

SELECT DATE_TRUNC('HOUR', created_at) AS hour_block,
       COUNT(*) AS orders_placed
FROM orders
WHERE created_at >= '2024-06-01'
GROUP BY hour_block
ORDER BY hour_block;

Business use: Visualize order volumes by hour for operational decisions.
