JSONB EXTRACT PATH Syntax in PostgreSQL

Function Overview

The jsonb_extract_path function retrieves a specified path from a jsonb column.

• Usage: Extracts nested JSONB fields using a precise path array.

Syntax

jsonb_extract_path(target_jsonb, VARIADIC path_elems)

• target_jsonb: The column or expression containing JSONB data.

• path_elems: One or more keys as text literals pointing to the nested JSON field.

PostgreSQL Syntax Note

• PostgreSQL uses jsonb_extract_path (not JSON_EXTRACT_PATH).

• Paths are provided as comma-separated arguments, not an array.
