Class DBTableAlias

java.lang.Object

adql.db.DefaultDBTable

adql.db.DBTableAlias

All Implemented Interfaces:

DBTable, java.lang.Iterable<DBColumn>

public class DBTableAlias
extends DefaultDBTable

This DBTable wraps another DBTable with a different ADQL and DB name.

This wrapper aims to represent in the metadata the aliasing of a table. This table should not be part of any schema, in ADQL but also in SQL...it is just an alias of an existing table.

All columns of the origin table are completely copied into this DBTable thanks to DBColumn.copy(String, String, DBTable), with the same ADQL and DB name but a different parent table (this one is used of the original one).

Note: The origin table is still available thanks to the function getOriginTable().
