What version of Access are you using?

Try this for Oracle:

select a.emp_id, a.emp_name,
	b.emp_grade_name,
	max(case when c.alw_ded_id = '1000' then alw_ded_name end) basic,
	max(case when c.alw_ded_id = '1001' then alw_ded_name end) accomadation,
	max(case when c.alw_ded_id = '1002' then alw_ded_name end) electricity,
	max(case when c.alw_ded_id = '1001' then alw_ded_name end) water
from table_a a,
	table_b b,
	table_c c,
	table_d d
where a.emp_grade_id=b.emp_grade_id and 
	a.emp_id=c.emp_id and
	c.alw_ded_id=d.alw_ded_id
group by a.emp_id, a.emp_name, b.emp_grade_name
/
