Count (Jobs by Company::iOne)

The count of the Jobs by Company relationship will return the nunber of jobs for the company. You can then either add 1 to that number (if the new job record has not yet been created.

However I strongly suggest that you do not use this kind of scheme for generating a job number. As soon as somebody deletes a job, you are screwed.

You could store a seperate Job Counter field in the company database and simply increment this number each time a job is entered, this way you know how many job have ever been entered and will not run into a problem if someone deletes a job record.

I am building a database that is a record of jobs.

Each job has an initial job number that is a standard 4 figure number which is self generating and sequential. i.e. 0001...0002...0003 etc.

Each job also carries a secondary job number that I want to be a figure that calculates the amount of jobs to a particular client then uses the next sequential figure.

i.e. we so far have 4 jobs that relate to company one. The next job number that is booked in relating to this client should be as follows:

initial job number 0025 (I have just selected a random number here)

the secondary job number needs to be "5". I.e. the 5th job relating to company one.

How do I formulate the secondary job number?
