Joins
What are Joins?
A join is a query that
combines rows from two or more tables, views, or materialized views.
Oracle Database
performs a join whenever multiple tables appear in the FROM clause of the
query.
The select list of the
query can select any columns from any of these tables.
If any two of these tables have a column name in common, then you must qualify all references to these columns throughout the query with table names to avoid ambiguity.
