Hi, all,
I have three tables; 'cv', the main table, 'jobcat', a definition table and 'cvjobcats', an intersection table (for more detail see PS below).
I'd like to join this all together to be able to make a headline consisting of the plain English description of the job category followed by all rows within cv which contain a reference to that job category
I can follow this only to a point and that is where I ask for the List's help - does this even resemble the beginnings of what I want to accomplish? I've tried to comment as I go for my own sanity
//Select columns from 'cv', whose 'category' references numbers //Select 'category' from 'jobcat' to translate the numbers to English
"SELECT cv.cv_id, cv.category, dates, cv.job_title, cv.company, cv.job, jobcat.category
FROM cv LEFT JOIN cvjobcats ON cvjobcats.cv=cv.cv_id //Let tables cv and jobcat understand each other.
//This next bit I'm confused about LEFT JOIN jobcat ON jobcat.jobcat_id=cvjobcats.jobcat WHERE cvjobcats.jobcat='4'";
Great. I'm now lost. Can anyone advise?
Thanks in advance,
PS:
<far too much information>
cv contains columns including an primary key ('cv_id') and a column called 'category' which refers to job categories by number.
jobcat contains two fields: a primary key (jobcat_id) and a plain english description
cvjobcat contains two key columns: 'cv_id' and 'jobcat_id'. </far too much information>
Hello Jackson
Are there any circumstances under which the cvjobcats table would have a job category entry that does not appear in the jobcats table? IF not, you really don't need to use the LEFT JOINS. Instead you coudl do something like this:
SELECT cv.cv_id,cv.category,dates,cv.job_title,cv.company,cv.job, jobcat.category
FROM cv, cvjobcats, jobcats
WHERE cvjobcats.cv=cv.cv_id AND cvjobcats_jobcat = 4 AND jobcat.jobcat_id=cvjobcats.jobcat
Less technically impressive perhaps but easier to follow ;)

Rory
