sql server - Combining SQL records that have the same the same value in a given field -


let's say, example, have following table

courseid                             | coursetitle | entrymonth | entryyear | ebdef239-abb7-4a82-9229-1ed37496da86 | maths ft    | january    | 2013      | 57504a66-4882-4794-a8b9-af0ead38dc70 | maths ft    | february   | 2013      | f06c5e58-5563-4dfd-a8fc-2ce186c2106f | maths ft    | february   | 2014      | 0c81dfe6-0b11-4cad-a27c-970dbdb2876c | maths ft    | february   | 2015      | ebdef239-abb7-4a82-9229-1ed37496da86 | english pt  | january    | 2013      | 57504a66-4882-4794-a8b9-af0ead38dc70 | english pt  | january    | 2014      |

is possible write query group coursetitle & entrymonth, combine entryyear values temporary column (preferably comma delimited). this:

courseid                             | coursetitle | entrymonth | newentryyear     | ebdef239-abb7-4a82-9229-1ed37496da86 | maths ft    | january    | 2013             | 57504a66-4882-4794-a8b9-af0ead38dc70 | maths ft    | february   | 2013, 2014, 2015 | ebdef239-abb7-4a82-9229-1ed37496da86 | english pt  | january    | 2013, 2014       |

any examples appreciated. thanks.

select  coursetitle ,       entrymonth ,       stuff((         select  ', ' + cast(entryyear varchar)            table1 t2           t1.coursetitle = t2.coursetitle                 , t1.entrymonth = t2.entrymonth         xml path('')         ), 1, 2, '') years    table1 t1 group         coursetitle ,       entrymonth

example @ sql fiddle.

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).
