Get properties for codings

Takes a Coding column as its input. Returns a Column that contains the values of properties for this coding with specified names and types. The type of the result column depends on the types of the properties. Primitive FHIR types are mapped to their corresponding SQL primitives. Complex types are mapped to their corresponding structs.

tx_property_of(
  coding,
  property_code,
  property_type = "string",
  accept_language = NULL
)

Arguments

property_code

The code of the property to retrieve.

property_type

The type of the property to retrieve.

accept_language
