Database datatype comparison sheet

Sometimes when writing automated SQL injection tools or exploit based on SQLi vulnerabilities you can fight with the different implementation of standard SQL datatype of DBMS.
Reading a lot of documentation i wrote a  comparison sheet between datatypes used by Mysql, SQL Server, Oracle, DB2, SQLite, PostgreSQL, Sybase ASE, Firebird.
You can download Adobe Acrobat [PDF] or OpenOffice [ODS].
