INNER JOIN 4桌

Question

I'm having a problem inner joining multiple tables. When I join any of the three tables it returns the results correctly. For instance:

SELECT jobLink.*
     , trucks.*
     , employees.* 
  FROM jobLink 
  JOIN schedule 
    ON jobLink.jobID = schedule.id 
  JOIN employees 
    ON jobLink.empID = employees.id 
 WHERE jobLink.thedate = '2014-18-07' 
   AND schedule.id =  439

Will return the jobname and all the employees on the job under it.

As soon as I join the last join I get an empty result leading me to believe that my order is off or something. I'm open to other suggestions as there is possibly a better or more efficient way to accomplish this so I'm listing my tables below. Any help is appreciated.

jobLink table:

id     |    jobID    |   empID   |   copy   |   truck   |    thedate
_____________________________________________________________________

employees table:

id     |    name    |   abb   |   pos   |   current   
_____________________________________________________________________

trucks table:

id     |    num    |   sort  
_____________________________________________________________________ 

schedule table:

id     |    name    |   address   |   city   |   phone   |    email
_____________________________________________________________________

My query is currently:

 SELECT jobLink.*
      , trucks.*
      , employees.* 
   FROM  jobLink   
   JOIN  schedule 
     ON jobLink.jobID = schedule.id 
   JOIN employees 
     ON jobLink.empID = employees.id 
   JOIN trucks 
     ON jobLink.truck = trucks.id 
  WHERE jobLink.thedate = '2014-18-07' 
    AND schedule.id = 439

Each table has a different quantity of results. Schedule has 1 result but the rest will vary depending on how many employees and trucks are on the job (from the schedule). Im trying to produce something like this:

the employees wont end up under the trucks because i dont have that set up in the db tables but can be listed before or after the employee list. Thanks in advance!

Answer 1

yes, the output is php sorry for not being more specific... @Strawberry after speaking to a colleague of mine, his suggestion is to change the structure. By changing the structure and adding a job_truck table and a job_employees table I am able to accomplish what I need by using inner joins. @RubahMalam yes i did try left joins but i am unable to accomplish it in one query. Thank you for the suggestions.
