oracle11g - Oracle SQL unsigned integer -


in oracle, equivalent mysql's unsigned?

i have following query, doesn't work:

create table foo (   id int unsigned not null primary key );

edit: purpose save space, because fields won't using negative values. alternatively, answer question of confirms i'm asking impossible in oracle 11g, or if it's possible, not straightforward (more 3 lines of code per unsigned int).

also, it's not int. use smallint , tinyint.

if want match restrictions shown here, can use check constraint:

sql> create table foo (id number primary key,      constraint foo_uint_id check (id between 0 , 4294967295));  table created.  sql> insert foo (id) values (-1);  insert foo (id) values (-1) * error @ line 1: ora-02290: check constraint (scott.foo_uint) violated  sql> insert foo (id) values (0);  1 row created.  sql> insert foo (id) values (4294967295);  1 row created.  sql> insert foo (id) values (4294967296);  insert foo (id) values (4294967296) * error @ line 1: ora-02290: check constraint (scott.foo_uint_id) violated  sql> select * foo;          id ----------          0 4294967295

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).
