mysql - How to achieve unique auto-incremented id for rows across multiple tables? -


i've got several tables in database, let's they're called table1, table 2, etc. tables have primary key column 'id' auto-increment.

in current configuration happens when inserting table1, generated id 1. afterwards when inserting table2, generated id happens 1 well.

how force absolutely unique ids across tables in database? want when inserting table1, generated id 1, , if afterwards inserting table2, generated id 2?

i used mysql server on machine , did not have problem, when installed mysql on local machine, started occur. guess must kind of setting applied mysql configuration?

thank you

you can use uuid. 

insert mytable(id, name) values(select uuid(), 'some data');

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).
