a.*,
from table1 a,
table2 b where ( a.employee_num = b.employee_num and a.test_id = 1 and a.employee_num = 'SA' and ((a.test_score >= b.test_score_min and a.test_score < b.test_score_max) or (a.test_score >= b.test_score_min and b.test_score_max is null ) ) and (case when b.department_flag is null then '1' when b.department_flag = 'Y' and a.department_flag = 'Y' then '1' when b.department_flag = 'N' and a.department_flag = 'N' then '1' else ' ' end ) = '1')
