Home > SQL Developer Dialog Boxes ... > Edit Join
This dialog box lets you edit the join specification for a join view.
Swap: Reverses the order of the tables.
Join Type:
Natural: If this option is checked, a natural join will be performed. A natural join is based on all columns in the two tables that have the same name. It selects rows from the two tables that have equal values in the relevant columns. When specifying columns that are involved in the natural join, do not qualify the column name with a table name or table alias.
On: Using the ON clause to specify a join condition lets you specify join conditions separate from any search or filter conditions in the WHERE clause.
Using: When you are specifying an equijoin of columns that have the same name in both tables, the USING column clause indicates the columns to be used. You can use this clause only if the join columns in both tables have the same name. Within this clause, do not qualify the column name with a table name or table alias. In an outer join with the USING clause, the query returns a single column which is a coalesce of the two matching columns in the join.
