Grouping and subtotalling - sql

Question

I am currently writing a report which I wish to group by the field apar_id and also have a sub total for each of these.
Given my limited knowledged and being bambozled by many google answer I am asking for your kind input.
My code is as follows:
SELECT d.apar_name,a.*,b.rel_value,c.dim_b
FROM acutrans a
LEFT JOIN aglrelvalue b ON a.apar_id=b.att_value
LEFT JOIN acrtrees c ON b.rel_value=c.cat_1
LEFT JOIN acuheader d ON a.apar_id=d.apar_id
WHERE b.rel_attr_id='212'
AND b.attribute_id='A4'
AND a.client='CL'
AND a.client=b.client
AND a.client=c.client
AND c.att_agrid='60'
AND (b.rel_value='X24' OR c.dim_b='PCT')
ORDER BY a.apar_id
The results are similar to
apar_id | ..... | amount.....
x 100
x 300
x -100
Y 400
Y 100
and would like
apar_id | ..... | amount.....
x 100
x 300
x -100
Total X 300
Y 400
Y 100
Total Y 500
Thanks in advance

Many databases support the with rollup clause for group by. If yours does, you can do what you want by making this a group by statement.
SELECT d.apar_name, sum(amount) as amount
FROM acutrans a
LEFT JOIN aglrelvalue b ON a.apar_id=b.att_value
LEFT JOIN acrtrees c ON b.rel_value=c.cat_1
LEFT JOIN acuheader d ON a.apar_id=d.apar_id
WHERE b.rel_attr_id='212'
AND b.attribute_id='A4'
AND a.client='CL'
AND a.client=b.client
AND a.client=c.client
AND c.att_agrid='60'
AND (b.rel_value='X24' OR c.dim_b='PCT')
GROUP BY d.apar_name WITH ROLLUP;
This will not specifically solve this problem, although you can adapt this solution (if your database supports it).
