Developers should use the ``++FROM ... OUTER JOIN++`` syntax rather than the Oracle join operator (``+``). The reason is that outer join queries that use ``+`` are subject to several restrictions which do not apply to the ``++FROM ... OUTER JOIN++`` syntax. For instance, a ``++WHERE++`` condition containing the ``+`` operator cannot be combined with another condition using the ``++OR++`` logical operator.


== Noncompliant Code Example

[source,sql]
----
BEGIN
  -- Noncompliant
  SELECT *
    INTO employeesArray
    FROM employee, department
    WHERE employee.DepartmentID = department.ID(+);
END;
/
----


== Compliant Solution

[source,sql]
----
BEGIN
  -- Compliant
  SELECT *
    INTO employeesArray
    FROM employee LEFT OUTER JOIN department
    ON employee.DepartmentID = department.ID;
END;
