c# - Why stored procedure result is zero? -

-

work on c# vs 2008. have stored procedure in sql server 2005. using linq-to-sql execute stored procedure, result zero. when run query in sql server it's work fine

 exec spgetinvoicebydate '03/01/2011 00:00:00 am','03/31/2011 11:59:59 pm'

above syntax works fine.

here sql server stored procedure

create procedure [spgetinvoicebydate]     @beginning_date datetime, @ending_date datetime     begin    select * #temp1 (   select     convert(varchar, manifestport.startdate, 1)+'-'+case dbo.manifestport.enddate when '1800-01-01 00:00:00.000' 'n/a' else convert(varchar, manifestport.enddate, 1) end [date], manifest.vesselname, manifest.voyageno, dischargeport.portname , manifestport.terminal, count(seal.containerno) totalcontainers, 0 totalhours, 0 totalfee   manifestport  inner join manifest on manifestport.manifestno = manifest.manifestno  inner join dischargeport on manifestport.portcode = dischargeport.portcode  inner join seal on manifestport.manifestportno = seal.manifestportno   (startdate between @beginning_date , @ending_date)                 group startdate,enddate, vesselname, voyageno, portname, terminal)    select * #temp2 (   select convert(varchar, manifestport.startdate, 1)+'-'+case dbo.manifestport.enddate when '1800-01-01 00:00:00.000' 'n/a' else convert(varchar, manifestport.enddate, 1) end [date], manifest.vesselname, manifest.voyageno, dischargeport.portname,  manifestport.terminal, count(seal.containerno) stotalcontainers, 0 stotalhours, 0 stotalfee   manifestport  inner join manifest on manifestport.manifestno = manifest.manifestno  inner join dischargeport on manifestport.portcode = dischargeport.portcode  inner join seal on manifestport.manifestportno = seal.manifestportno   (startdate between @beginning_date , @ending_date ) , line = 'csav'   group startdate,enddate, vesselname, voyageno, portname, terminal     ) b    select  #temp1.date,           #temp1.vesselname ,           #temp1.voyageno ,           #temp1.portname ,           #temp1.terminal ,           #temp1.totalcontainers ,           #temp1.totalhours ,           #temp1.totalfee, #temp2.stotalcontainers, #temp2.stotalhours, #temp2.stotalfee #temp1 inner join #temp2           on #temp1.date = #temp2.date , #temp1.portname = #temp2.portname , #temp1.terminal = #temp2.terminal , #temp1.vesselname = #temp2.vesselname           , #temp1.voyageno = #temp2.voyageno            order #temp1.vesselname, #temp1.voyageno    drop table #temp1   drop table #temp2    end

i use c# linq syntax execute stored procedure:

datetime firstdayofmonth = convert.todatetime("03/01/2011"); datetime lastdayofmonth = convert.todatetime("03/31/2011");  var results = providername.spgetinvoicebydate(firstdayofmonth,lastdayofmonth);

why result zero?

can tell me how reduce problem?

thanks in advance, if have question, please ask.

have tried executing stored proc (on sql server management studio) replacing @beginning_date , @ending_date values pass in c# linq code? return result? if it's 0, explains why linq code returns 0.

hope helps.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
