sql - How do I return multiple column values as new rows in Oracle 10g? -


i have table multiple account numbers associated different ids(dr_name). each account have few 0 accounts, , many 16. believe unpivot work, i'm on oracle 10g, not support this. 

dr_name   acct1   acct2   acct3   acc4   ====================================== smith     1234 jones     5678    2541    2547 mark      null     ward      8754    6547

i want display new line each name 1 account number per line

dr_name   acct ============== smith     1234 jones     5678 jones     2541 jones     2547 mark      null ward      8754 ward      6547

oracle 10g not have unpivot function can use union all query unpivot columns rows:

select t1.dr_name, d.acct yourtable t1 left join (   select dr_name, acct1 acct   yourtable   acct1 not null   union   select dr_name, acct2 acct   yourtable   acct2 not null   union   select dr_name, acct3 acct   yourtable   acct3 not null   union   select dr_name, acct4 acct   yourtable   acct4 not null ) d   on t1.dr_name = d.dr_name;

see sql fiddle demo.

this query uses union all convert columns rows. included where clause remove null values, otherwise multiple rows each account acct value null. excluding null values drop dr_name = mark showed want in final result. include rows have null values, added join table again.

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).
