SSC-EWI-0022

One or more identifiers in a specific statement are considered parameters by default.

The EWI is only generated when Javascript is the target language for Stored Procedures. This is a deprecated translation feature, as Snowflake Scripting is the recommended target language for Stored Procedures.

Some parts in the output code are omitted for clarity reasons.
