Expand description

An element of a JSON path.

Variants§

Dot

Accesses an object field using dot notation, e.g. obj:foo.bar.baz.

§quoted: bool

true when the key was quoted in the source.

Bracket

Accesses an object field or array element using bracket notation, e.g. obj['foo'].

See https://docs.snowflake.com/en/user-guide/querying-semistructured#bracket-notation.

Fields

§key: Expr

The expression used as the bracket key (string or numeric expression).
