ToDo List for DBI

# ToDo

- SQL statement parser like Perl's SQL::Statement
- LDAP DBD
- column_info: precision == column_size or == column_size - scale ???
- fetch_many callable as iterator
- make SQL::bind preparable (parse SQL statement before)
- columns / column_info with more DBDs (DB2, Oracle, Interbase, ODBC)
- Tainting
- table_info
- bind_param_inout
- type_info / type_info_all
- bind_col ?
- Rewrite DBI-dispatching in C?
- warn if commit/rollback and AutoCommit is on
- bind_out_param/bind_inout_param
- tracing/logging for DBDs by calling log(...)
- define exact behaviour of fetch_scroll
- define exact behaviour of exception classes
- do not pass *args paramters to DBD (it's harder for C-extensions to handle them)
- thead safety ?
- asynchronous execution

# Done

- fetch_all should always return an array, as well as select_all etc., fetch_many always []
- get a Driver object, call methods on it
- blob_import etc. for DBD::Pg
- parameter markers in DB2
