Test membership within a value set

Takes a Coding, an array of Codings or a string column of codes as its input. Returns the column which contains a Boolean value, indicating whether any of the input Codings, or the code, is a member of the specified FHIR ValueSet. The value is null where membership cannot be determined, for example because the value set cannot be resolved.

tx_member_of(codings, value_set_uri)

Arguments

A Column containing a struct representation of a Coding or an array of such structs, or a string column of codes whose system is inferred from the value set.

value_set_uri

An identifier for a FHIR ValueSet.

Value

A Column containing the result of the operation.
