I’m currently working on my Master degree thesis and I’m projecting a demo database about a Mammography archive. The purpose is providing an archive, whose clinical cases can be consulted on a portal page by a user interface.
I must create a database for a Liferay portal. Liferay is a very powerful opensouce CMS / web application framework written in Java that allows creating the database and the queries by an xml file.
Before developing the portlet I need to study the situation. I’m analyzing and evaluating the query formulations, as I will have to develop GUIs to consult the image (Echography) archive and upload new cases.
I’ve started with some sql scripts.
I’ve made a sql script to create and populate the Mammography database. Then I’ve made another script to add the archive zip file size of each clinical case and a stored procedure to update the volume table (grouping clinical cases of the same category) with the sum of the cases’ zip file size.

The script to create and populate the DB is:

/* access database */

Then I’ve considered adding columns:
ALTER TABLE volume ADD COLUMN total_size VARCHAR(10);
ALTER TABLE case_archive ADD COLUMN size_zip_MB FLOAT NOT NULL
(10);
And populate them:
UPDATE case_archive SET size_zip_MB=200.1 where id_case=1;
UPDATE case_archive SET size_zip_MB=460.2 where id_case=2;
UPDATE case_archive SET size_zip_MB=2154.5 where id_case=3;
UPDATE case_archive SET size_zip_MB=225.3 where id_case=4;
To calculate the sum of the zip files’ size of the cases for each row of the volume table I’ve made the following procedure:
DELIMITER //
CREATE PROCEDURE volume_total_size()
BEGIN
DECLARE i int(10);
DECLARE l int(10);
SET i=0;
set l= (SELECT COUNT(*) from volume);
WHILE i<l DO
SET i=i+1;
UPDATE volume SET total_size= (select IF(sum(case_archive.size_zip_MB)>1024.0, CONCAT(TRUNCATE(sum(case_archive.size_zip_MB)/1024,1),'GB' ),
CONCAT(sum(case_archive.size_zip_MB),'MB')) as total_size
from case_archive
where id_volume=i)
where id_volume=i;
SELECT * FROM volume;
END;
To invoke procedure type in the console:
MySQL> call volume_total_size();
You can also copy the command in a new *.sql file and launch the script.
I’ve tested the whole “project” with MySQL 5.5.
I have decided to share this because I have spent several hours trying to understand how to update the volume table with the sum of the file size.
Notice that in the ‘case_archive‘ table the column ‘size_zip_MB‘ type is INT(10)
and you have to insert the size in MB, while in ‘volume‘ the ‘total_size‘ column type is VARCHAR(10)
. MySQL 5.5 casts the column type automatically 🙂
