Hi there .. in order to look at the structure the database you might be able to install an application into the web server called phpmyadmin which will allow you to open database, browse the tables and columns.
If you needc to use reportico to do that then you can create new report... open the sql text box and paste in the following
SELECT table_name,GROUP_CONCAT(column_name ORDER BY ordinal_position)
columnname
FROM information_schema.columns
WHERE table_schema = DATABASE()
GROUP BY table_name
ORDER BY table_name
that will give you a summary view,
or to show one line per column do
SELECT table_name,column_name
FROM information_schema.columns
WHERE table_schema = DATABASE()
