Question

Using Oracle Proprietary join syntax, which operator would you use after one of the column names in the WHERE clause when creating an outer join?

A.(+)
B.+
C.*
D.=

Answer 1

The correct operator to use after one of the column names in the WHERE clause when creating an outer join using Oracle Proprietary join syntax is (+).

Step-by-step explanation:

The operator used after one of the column names in the WHERE clause when creating an outer join using Oracle Proprietary join syntax is B. +. An example of its usage is in a query where you are trying to retrieve all rows from the left table (table1) and the matching rows from the right table (table2), and if there is no match, NULL values are returned for the columns of the right table. The outer join condition is specified in the WHERE clause of the query and would look something like table1.column_name = table2.column_name(+).

The correct operator to use after one of the column names in the WHERE clause when creating an outer join using Oracle Proprietary join syntax is (+). The (+) operator is used to denote the outer join in Oracle and is placed on the side of the join where null values may be produced.
