org.apache.calcite.sql.validate

Class ProcedureNamespace

java.lang.Object

org.apache.calcite.sql.validate.ProcedureNamespace

All Implemented Interfaces:

org.apache.calcite.sql.validate.SqlValidatorNamespace

@Internal
public final class ProcedureNamespace
extends Object

Namespace whose contents are defined by the result of a call to a user-defined procedure.

Note: Compared to Calcite, this class implements custom logic for dealing with collection tables like TABLE(function(...)) procedures. Compared to the SQL standard, Flink's table functions can return arbitrary types that are wrapped into a ROW type if necessary. We don't interpret ARRAY or MULTISET types as it would be standard.
