Using data from 5 different tables on a mysql query - mysql

Question

I need some help on doing multiple Joins, im not very good at this and need a way to get it to work.
There are 5 tables with data and need to get data to output from each table. There is a person, visit, center, date and seenby table. The visit table has ID's to fetch data from other tables. I want to use this table to get the status of the person, to see what date they visited, at what center, their name, and who they were seen by. (i hope this makes sense).
The output should look hopefully like this:
> Person FirstName
> Person LastName
> Seen By
> Date
> Center
> Status
EDIT// Here is a mockup of what i want to see
Ive already read up on pivot tables and would prefer not to use that. Ive created a SQL fiddle here:

EDIT//
Ive managed to write half a query but i doubt it works but i guess its a starting point.
SELECT d.date
, p.Firstname
, p.Lastname
, c.centername
, v.status
, s.FirstName
, s.LastName
FROM visit v
LEFT
JOIN date d
ON v.dateID = d.id
LEFT
JOIN centerName c
ON c.centerID = c.id
Thanks!

Answer 1

From your table structure it would seem you want a query like this:
SELECT
d.date,
CONCAT_WS(' ', p.Firstname ,p.Lastname) AS "Person",
v.status,
CONCAT_WS(' ', s.FirstName, s.LastName) AS "Seenby",
c.centername
FROM visit v
JOIN person p ON v.PersonID = p.ID
JOIN seenby s ON v.seenbyID = s.ID
LEFT JOIN date d ON v.dateID = d.id
LEFT JOIN center c ON v.centerID = c.id
The last two joins should maybe be normal inner joins and not left joins, adjust as appropriate.
TheCONCAT_WS()function concatenates its parameters into a string, using the value of the first parameter as separator (a space in this case).
