Functions

apply_json_type_hint 🔒

Sets the native read type for an exact hinted object path. Both SQL syntaxes use this before an enclosing expression can infer a type or push down a cast.

extract_json_get_type 🔒

extract_untyped_json_get 🔒

fallback_json_get_type 🔒

function_arg_field 🔒

infer_json_get_types 🔒

is_untyped_json_get 🔒

json_get_object_path 🔒

Resolves json_get’s second argument expression (the path) to object field names for type hint lookup. For example, the string literal '$.user.age' resolves to ["user", "age"].

json_get_output_type 🔒

json_path_field 🔒

Quotes field names containing JSONPath punctuation, preserving literal keys.

json_type_hint 🔒

Returns the configured native type for an exact JSON2 object path.

parse_sql_op 🔒

push_function_arg_types 🔒

Infers static output types for untyped json_get arguments from a function signature.
