=head1 CHANGES in DBI 1.42 (svn rev 208), 9th March 2004
Fixed $sth->{NUM_OF_FIELDS} of non-executed statement handle
to be undef as per the docs (it was 0).
Fixed t/41prof_dump.t to work with perl5.9.1.
Fixed DBD_ATTRIB_DELETE macro thanks to Marco Paskamp.
Fixed DBI::PurePerl looks_like_number() and $DBI::rows.
Changed attributes (NAME, TYPE etc) of non-executed statement
handle to be undef instead of triggering an error.
Changed ShowErrorStatement to apply to more $dbh methods.
Changed DBI_TRACE env var so just does this at load time:
DBI->trace(split '=', $ENV{DBI_TRACE}, 2);
Improved "invalid number of parameters" error message.
Major tracing enhancement:
Added $h->parse_trace_flags("foo|SQL|7") to map a group of
trace flags into the corresponding trace flag bits.
Added automatic calling of parse_trace_flags() if
setting the trace level to a non-numeric value:
$h->{TraceLevel}="foo|SQL|7"; $h->trace("foo|SQL|7");
DBI->connect("dbi:Driver(TraceLevel=SQL|foo):...", ...);
Currently no trace flags have been defined.
Added to, and reworked, the trace documentation.
Added dbivport.h for driver authors to use.
Major driver additions that Jeff Zucker and I have been working on:
Added DBI::SQL::Nano a 'smaller than micro' SQL parser
with an SQL::Statement compatible API. If SQL::Statement
is installed then DBI::SQL::Nano becomes an empty subclass
of SQL::Statement, unless the DBI_SQL_NANO env var is true.
Added DBD::File, modified to use DBI::SQL::Nano.
Added DBD::DBM, an SQL interface to DBM files using DBD::File.
Documentation changes:
Corrected typos in docs thanks to Steffen Goeldner.
Corrected execute_for_fetch example thanks to Dean Arnold.
=cut
Testing on a range of platforms, perl configs and drivers would be
appreciated.
I'd also like driver authors to consider/try-out the new
- dbvport.h mechanism (see DBI::DBD docs)
- The DBIc_TRACE_LEVEL(imp_xxh) macro
- DBIc_SET_ERR_* macros
- Recording 'success with info' (incl db messages etc) and 'warnings'
- bind_param() TYPE attribute specification
- bind_col() TYPE attribute specification
Thanks!
Tim.
