Package dev.frostlake.functions.table

Class TagReferencesFunction

java.lang.Object

dev.frostlake.functions.TableFunction

dev.frostlake.functions.table.TagReferencesFunction

public class TagReferencesFunction
extends TableFunction

The INFORMATION_SCHEMA.TAG_REFERENCES(object_name, object_domain) TABLE FUNCTION — the tags attached to one object, as SELECT … FROM TABLE(INFORMATION_SCHEMA.TAG_REFERENCES('db.schema.t', 'TABLE')).

Both arguments are required. The object name may be bare or qualified, and resolves against the session's current database and schema when it is not. A real account takes TABLE for every table-like object — passing VIEW is refused with "Please use object type TABLE for all kinds of table-like objects" — and takes COLUMN with a four-part name whose last part is the column.
