Description

Redshift allows the use of CALL statements within out parameters as top-level code units without defining a variable that would be assigned as output. Snowflake enforces the usage of a variable to set the output value somewhere.

Code Example

Input Code:

Redshift

IN -> Redshift_01.sql

CREATE OR REPLACE PROCEDURE get_total_sales_by_product(
    IN p_product_name VARCHAR(100),
    OUT p_total_sales DECIMAL(18, 2)
)
AS $$
BEGIN
    NULL;
END;
$$ LANGUAGE plpgsql;

CALL get_total_sales_by_product('Laptop');

Output Code:

Snowflake

OUT -> Redshift_01.sql

CREATE OR REPLACE PROCEDURE get_total_sales_by_product (p_product_name VARCHAR(100), p_total_sales OUT DECIMAL(18, 2))
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{ "origin": "sf_sc", "name": "snowconvert", "version": {  "major": 0,  "minor": 0,  "patch": "0" }, "attributes": {  "component": "redshift",  "convertedOn": "07/10/2025",  "domain": "no-domain-provided" }}'
AS $$

CALL get_total_sales_by_product('Laptop');

Recommendations

• Move the call into an anonymous block and declare a variable to pass as an output parameter.
