Re-qwrite Oracle SQL using ANSI Oracle - sql

Question

I am new to oracle and sql, I would like to know how can I re-write the following sql query using Oracle ANSI join conditions.
SELECT emp_no,
(SELECT emp_title
FROM hr_v_employee
WHERE organization_code LIKE
SUBSTR (emp.depart_code, 0, 4) || '00'
AND emp_position_code =
(SELECT MIN (emp_position_code)
FROM hr_v_employee
WHERE organization_code LIKE
SUBSTR (emp.depart_code,
0,
4
)
|| '00'))
|| ' '
|| NVL (employee_deptartment, '-')
employee_deptartment
FROM employees e, employee_details o
WHERE emp.emp_no = o.emp_no(+)
Edit 1
This what I have tried, my question is it possible to use join or ANSI standard for sub-query as well?
SELECT emp_no,
(SELECT emp_title
FROM hr_v_employee
WHERE organization_code LIKE
SUBSTR (emp.depart_code, 0, 4) || '00'
AND emp_position_code =
(SELECT MIN (emp_position_code)
FROM hr_v_employee
WHERE organization_code LIKE
SUBSTR (emp.depart_code,
0,
4
)
|| '00'))
|| ' '
|| NVL (employee_deptartment, '-')
employee_deptartment
FROM employees e left outer join employee_details o (emp.emp_no = o.emp_no)

Answer 1

Apart from the missing ON keyword for the LEFT OUTER JOIN, your query should be fine:
SELECT emp_no,
(SELECT emp_title
FROM hr_v_employee
WHERE organization_code LIKE SUBSTR(emp.depart_code,
0,
4) || '00'
AND emp_position_code =
(SELECT MIN(emp_position_code)
FROM hr_v_employee
WHERE organization_code LIKE SUBSTR(emp.depart_code,
0,
4) || '00')) || ' ' ||
NVL(employee_deptartment,
'-') employee_deptartment
FROM employees e
LEFT OUTER JOIN employee_details o
ON emp.emp_no = o.emp_no
Please note that you have a typo in your column names - it should be called employee_department instead of employee_deptartment.
