Budget and Cost Report

I am currently working on the above report.  The monthly budgets are contained in one table, the costs in another.  If work from the budgets table to costs I can see all costs against a cost code that has a budget, but if costs are incurred against a cost code that doesn't have a budget this will be missed.  I could work the other way from costs to budgets but the report wouldn't show costs codes that had a budget but where no costs had been incurred.

Please can someone advise on the best approach?

Use an outer join to get all costs with their budgets (or lack thereof)

Select...
from Costs c left join budgets b on c.costcode = b.costcode

go the other way to get all budgets with their costs (or lack thereof)
Select...
from Costs c right join budgets b on c.costcode = b.costcode

Most reports are best developed with one of the above forms.  To see it both ways, probably best to use two reports or two sub-reports.


You can also use full outer join  to get all budgets and all costs at one time, but it gets a little tricky developing a meaningful report when sometimes the budgets are missing and sometimes the costs are missing.

Select...
from Costs c full outer join budgets b on c.costcode = b.costcode
