sql - Using a Parameterized column in a Where Clause using Case -


i building report in ssrs need able let our users filter on different date fields. need able select date filter , start , end dates within filter.

this simplified example of trying achieve: 

select project.projectid, project.name, project.update_date, project.due_date, project.start_date, project.review_date project @datetypefiler between @startdate , @enddate

where @datetypefiler equal field user wishes filter on (i.e. project.update_date or project.due_date etc)

on ssrs built parameters @datetypefiler equal various date fields , set start date , end date filter expected.

unfortunately not seem though can parameterize @datetypefiler in way? attempted use case keyword so: 

select project.projectid, project.name, project.update_date, project.due_date, project.start_date, project.review_date project case  when @datetypefiler='project.update_date' project.update_date between @startdate , @enddate when @datetypefiler='project.due_date' project.due_date between @startdate , @enddate

this isnt working me either, figure instead of taking shots in dark should ask correct method like. advice on appreciated,

or try this

select project.projectid, project.name, project.update_date, project.due_date,  project.start_date, project.review_date  project  (case  when @datetypefiler = 'project.update_date' project.update_date  when @datetypefiler= 'project.due_date' project.due_date  end) between @startdate , @enddate

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
