convert string into int SQL Server -


this scenario:

my app have following:

  1. a listbox (the checkbox property enabled) display list of something.
  2. the user select listbox (multiselect) using checkbox.
  3. i loop checked items , store id's array. store id's separating id comma (1,2,3,4) , use length -1 delete last comma.

how can convert string 1,2,3,4 integer type of data if stored procedure this?

select * tblsomething id in (1,2,3,4)

you can use following sql function.

set ansi_nulls on go  set quoted_identifier on go  create function [dbo].[commaseparatedtostring] (    @pscsstring varchar(8000) )  returns @ottemp table(sid varchar(20)) begin declare @stemp varchar(50) while len(@pscsstring) > 0 begin set @stemp = left(@pscsstring, isnull(nullif(charindex(',', @pscsstring) - 1, -1),                 len(@pscsstring))) set @pscsstring = substring(@pscsstring,isnull(nullif(charindex(',', @pscsstring), 0),                            len(@pscsstring)) + 1, len(@pscsstring)) insert @ottemp values (@stemp) end return end

and call in stored procedure 

select * tblsomething  id in (select * commaseparatedtostring('1,2,3,4'))

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).
