Struct arrow_flight::sql::CommandGetTableTypes
source · pub struct CommandGetTableTypes {}
Expand description
Represents a request to retrieve the list of table types on a Flight SQL enabled backend. The table types depend on vendor/implementation. It is usually used to separate tables from views or system tables. TABLE, VIEW, and SYSTEM TABLE are commonly supported. Used in the command member of FlightDescriptor for the following RPC calls:
- GetSchema: return the Arrow schema of the query.
- GetFlightInfo: execute the catalog metadata request.
The returned Arrow schema will be: < table_type: utf8 not null > The returned data should be ordered by table_type.
