Code Inspection: Missing return statement

This inspection reports functions that miss return statements.

For example, consider the following code block for Oracle.

create function foo(n int) return int as begin case when n > 1 then return 1; when n < -1 then return -1; end case; end;

According to the RETURN Clause chapter in the Oracle documentation, the function must return a value. In our example, we must return the int value to have a valid code.
