I have a table schema like this mysql> desc material_out; <pre>`enter code here` +-------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+-------+ | id | int(11) | NO | | 0 | | | barcode | varchar(20) | NO | | NULL | | | name | varchar(100) | NO | | NULL | | | qty | double | YES | | NULL | | | unit | varchar(20) | YES | | NULL | | | num_letter | varchar(30) | YES | | NULL | | | date | date | YES | | NULL | | | destination | varchar(50) | YES | | NULL | | +-------------+--------------+------+-----+---------+-------+ 8 rows in set (0.00 sec) </pre> mysql> desc material_in; <pre>`enter code here` +-------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+-------+ | id | int(11) | NO | | 0 | | | barcode | varchar(20) | NO | | NULL | | | name | varchar(100) | NO | | NULL | | | qty | double | YES | | NULL | | | unit | varchar(20) | YES | | NULL | | | num_letter | varchar(30) | YES | | NULL | | | date | date | YES | | NULL | | | destination | varchar(50) | YES | | NULL | | +-------------+--------------+------+-----+---------+-------+ 8 rows in set (0.00 sec) </pre> mysql> desc goods; <pre>`enter code here` +-------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+--------------+------+-----+---------+-------+ | id | int(11) | NO | | 0 | | | barcode | varchar(20) | NO | | NULL | | | name | varchar(100) | NO | | NULL | | | unit | varchar(20) | YES | | NULL | | | category | varchar(25) | YES | | NULL | | | first_stok | double ) | YES | | NULL | | +-------------+--------------+------+-----+---------+-------+ 6 rows in set (0.00 sec) </pre> In table material_out I have data of 10,000 rows. and has as many as 350 types of barcodes. In table material_in I have data around 15,000 rows. and has as many as 200 types of barcodes. but i have a problem when doing a query. takes a long time probably about 3 hours. I think this is not efficient when you want to print a report. my query like this. <pre><code>SELECT br.barcode, out.total_out, in.total_in, out.total_out - in.total_in AS RESULT FROM (SELECT barcode, name, first_stok, unit FROM goods WHERE category=1) AS br LEFT JOIN (SELECT (SELECT sum(qty) FROM material_out WHERE date >= '2013-08-15' AND tanggal <='2013-08-20' AND barcode=a.barcode) AS total_out FROM material_out a GROUP BY a.barcode) AS OUT ON OUT.barcode=br.barcode LEFT JOIN (SELECT (SELECT sum(qty) FROM material_in WHERE date >= '2013-08-15' AND tanggal <='2013-08-20' AND barcode=a.barcode) AS total_in FROM material_in a GROUP BY a.barcode) AS IN ON IN.barcode=br.barcode </code></pre> edited bro.. new query from realitygone. <pre><code><pre> mysql> SELECT tNEW.barcode, -> tNEW.total_out, tNEW.total_in, tNEW.result, -> tOLD.total_out AS total_out_old, tOLD.total_in AS total_in_old, tNEW.total_in + tOLD.total_in - tNEW.total_out - tOLD.total_out as sum_total -> FROM ( -> SELECT goods.barcode, -> SUM(tOUT.qty) AS total_out, -> SUM(tIN.qty) AS total_in, -> SUM(tIN.qty) - SUM(tOUT.qty) AS result -> FROM goods -> LEFT JOIN material_out AS tOUT ON tOUT.barcode=goods.barcode -> LEFT JOIN material_in AS tIN ON tIN.kode=goods.barcode -> WHERE goods.category=1 -> AND tOUT.date BETWEEN '2013-05-01' AND '2013-08-31' -> AND tIN.date BETWEEN '2013-05-1' AND '2013-08-31' -> GROUP BY goods.barcode -> ) AS tNEW -> LEFT JOIN ( -> SELECT goods.barcode, -> SUM(tOUT.qty) AS total_out, -> SUM(tIN.qty) AS total_in -> FROM goods -> LEFT JOIN material_out AS tOUT ON tOUT.barcode=goods.barcode -> LEFT JOIN material_in AS tIN ON tIN.kode=goods.barcode -> WHERE goods.category=1 -> AND tOUT.date BETWEEN '2013-01-01' AND '2013-04-31' -> AND tIN.date BETWEEN '2013-01-01' AND '2013-04-31' -> GROUP BY goods.barcode -> ) AS tOLD ON tOLD.barcode=tNEW.barcode;

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
