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.

Position the caret at the highlighted line and press Alt+Enter or click .
Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
