sql server - How to get date of previous year for a certain month and day... and vice versa for current year -

-

i wondering if assist me dilemma, have piece of sql has return amount in current time line, start date has 2014-03-01 , end date 2015-03-01. tricky part should change every year automatically dont have change it, example next year should 2015-03-01 , 2016-03-01.

the sql have written:

 select c.name biller,sum(totaltransactions) totaltransactions,    sum(totalpay@fee)/1.14 totalpay@fee  tblpay@dailyretailerbillertotals d   left outer join tblpay@company c (nolock) on d.clientid = c.recid   name = 'name of biller'  , datecreated >= 'start date' --2014-03-01  , datecreated <  'end date' -- 2015-03-01  group c.name  order c.name asc

the following should give dates need:

select  yearstart = cast(cast(                             datepart(year, getdate()) -                                  case when datepart(month, getdate()) < 3                                      -1                                      else 0                                  end varchar(4)) + '0301' date),         yearend = cast(cast(                             datepart(year, getdate()) -                                  case when datepart(month, getdate()) < 3                                      0                                      else 1                                  end varchar(4)) + '0301' date);

the principle year, add '0301' (1st march) date. need apply logic correct year, if date january of february, need deduct 1 year previous 1st march.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
