Description

This functional difference message indicates that while Snowflake supports the function's syntax (either directly or through an equivalent mapping), its behavior might be different from the original in some situations.

Code Example

Input Code:

Redshift

IN -> Redshift_01.sql

SELECT
    LISTAGG(skill) WITHIN GROUP (ORDER BY skill) OVER (PARTITION BY
    employee_name) AS employee_skills
FROM
    employees;

Output Code:

Snowflake

OUT -> Redshift_01.sql

SELECT
--** SSC-FDM-PG0013 - FUNCTION SYNTACTICALLY SUPPORTED BY SNOWFLAKE BUT MAY HAVE FUNCTIONAL DIFFERENCES **
LISTAGG(skill) WITHIN GROUP (ORDER BY skill) OVER (PARTITION BY
employee_name) AS employee_skills
FROM
    employees;

Recommendations

• Carefully evaluate the functional behavior for unexpected results, as differences may only occur in specific scenarios.
