How to pass NEW/OLD to procedures called from trigger functions in PostgreSQL? -


let's suppose have trigger function, code complex handy split more procedures. want operate new (or old update/delete triggers) variable in of them. there alternative sending function parameter every procedure called original trigger function?

if need pass them around, i'm quite sure can appropriately typed records (e.g. newrow tablename%rowtype).

http://www.postgresql.org/docs/current/static/plpgsql-declarations.html

that said, unless run giant queries results use throughout trigger function, breaking trigger smaller parts cleaner calling subfunctions imho. note can conditionally execute triggers, e.g.:

create trigger "01_do_stuff_upd" on update after tablename   each row   when (old.field <> new.field , ...) execute procedure do_stuff_upd_part_01();

the thing have in mind when doing above, in postgres (and contrary sql spec), triggers executed in alphabetical order rather in order they're created.

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).
