problem: 1: number of column unknown (max 200) in excel sheet.

i have converted excel sheet xml document , have passed parameter sql server. how use unknown column biggest problem.

if has done before, give brief description how it. xml xmldocument, passing billingconfig procedure.

sqlcommand cmd = new sqlcommand("billingconfig", con); cmd.commandtype = commandtype.storedprocedure; cmd.parameters.add("@info", sqldbtype.varchar).value = xml.innerxml;

help appreciated

this can done using cursor in sqlserver.

  1. get column names using

    select distinct cast(attribute.name.query('local-name(.)') varchar(100)) columnname  @xml.nodes('//@*') attribute(name)

  2. validate columns

  3. apply cursor on these convert columns rows

    declare @id varchar(10) declare @loc varchar(25) set @loc = '/mainitem/subitem';  declare @query varchar(max)          declare mycursor cursor local fast_forward     select * @tempcolumnname  open mycursor fetch next mycursor @id  while @@fetch_status = 0  begin    set @query = 'select * openxml(@hdoc, '+@loc+', 3) (xyz int)'    exec (@query)     fetch next mycursor @id end

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
