MySQL to get the count of rows for each worker with specific dates and jobs -

-

i have database of workers , assigned work items. want create report using mysql show count of how many work items under jobs , within date ranges each worker has. resulting data this:

            today          tomorrow        next year worker | job1 job2 job3 | job1 job2 job3 | job1 job2 job3  bob    |  4    0   1    | 1    2    0    | 5    10   3

i have 1 table following relevant fields: worker, date, jobtype, workitem

each worker has multiple entries under same name, bob have multiple workitems assigned him, this:

bob | 07/27/2011 | sandblasting | workitem001 bob | 08/30/2011 | mowing | workitem001 bob | 08/30/2011 | driving | workitem002

workitems can assigned multiple jobtypes.

i wrote confusing loops multiple queries, ideally want write single, complex query accomplish this. possible?

overview each day:

select worker, date, job, count(*) count workitems group worker, date, job

overview month/year:

select worker, month(date) month, job, count(*) count workitems group worker, month, job

that's it. table format little different in mysql cannot put values columns (job1, job2, job3 in example), possible e.g. ms access' cross query. can export data mysql above queries , e.g. use ms excel contingency tables produce output want.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
