CHARINDEX in Snowflake - Examples & AI Generator

Mastering the CHARINDEX function in Snowflake can be confusing, especially if you work with several databases—each with subtle differences in string search syntax. For SQL developers, data analysts, and database engineers, remembering Snowflake’s exact CHARINDEX structure slows down productivity. AI2sql eliminates the need to memorize or research CHARINDEX syntax by instantly turning your requirements into ready-to-use SQL—no code or reference guides needed.

CHARINDEX Syntax in Snowflake

In Snowflake, CHARINDEX finds the position of a substring within a string, starting the count at 1:

CHARINDEX(substring, string [, start_position])

• substring: Text to search for

• string: Target string to search in

• start_position (optional): Position to begin search

Key difference: In Snowflake, positions start at 1—not 0 as in some other SQL dialects.

CHARINDEX Examples You Can Generate Instantly

1. Find First Name in Customer Data

SELECT customer_name, CHARINDEX(' ', customer_name) AS first_space_pos
FROM customers;

Business use: Quickly extract first names by locating the first space in full names.

2. Check Position of a Product Code Section

SELECT product_id, CHARINDEX('-', product_code) AS dash_position
FROM products;

Business use: Identify where a separator appears in product codes for parsing SKUs.

3. Find Substring Position After a Given Index

SELECT order_id, CHARINDEX('-', order_reference, 5) AS position_after_fifth_char
FROM orders;

Business use: Locate character positions after a certain point, helpful for custom reference parsing.
