sql server 2008 - TSQL allocate variables from child result set to avoid repeating query -


is there way efficiently improve on code below without repeating query this?

note: there known number of elements assigning arguments in case.

select  @var0 = field_a table_0  join table_1 on (table_0.pk = table_1.fk)  table_1.pk = 1 , table_0.field_b = 1;  select  @var1 = field_a table_0  join table_1 on (table_0.pk = table_1.fk)  table_1.pk = 1 , table_0.field_b = 2;  select  @var2 = field_a table_0  join table_1 on (table_0.pk = table_1.fk)  table_1.pk = 1 , table_0.field_b = 3;

something this:

select     @var0 = max( case table_0.field_b when 1 field_a end )     , @var1 =   max( case table_0.field_b when 2 field_a end )     , @var2 =   max( case table_0.field_b when 3 field_a end )      table_0 join     table_1      on          table_0.pk = table_1.fk

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).
