Changes in DBI 1.21, 7th February 2002
The minimum supported perl version is now 5.005_03.
Fixed DBD::Proxy support for AutoCommit thanks to Jochen Wiedmann.
Fixed DBI::ProxyServer bind_param(_inout) handing thanks to Oleg Mechtcheriakov.
Fixed DBI::ProxyServer fetch loop thanks to [EMAIL PROTECTED]
Fixed install_driver do-the-right-thing with $@ on error. It, and connect(),
will leave $@ empty on success and holding the error message on error.
Thanks to Jay Lawrence, Gavin Sherlock and others for the bug report.
Fixed fetchrow_hashref to assign columns to the hash left-to-right
so later fields with the same name overwrite earlier ones
as per DBI < 1.15, thanks to Kay Roepke.
Changed tables() to use quote_indentifier() if the driver returns a
true value for $dbh->get_info(29) # SQL_IDENTIFIER_QUOTE_CHAR
Changed ping() so it no longer triggers RaiseError/PrintError.
Changed connect() to not call $class->install_driver unless needed.
Changed DESTROY to catch fatal exceptions and append to $@.
Added ISO SQL/CLI & ODBCv3 data type definitions thanks to Steffen Goeldner.
Removed the definition of SQL_BIGINT data type constant as the value is
inconsistent between standards (ODBC=-5, SQL/CLI=25).
Added $dbh->column_info(...) thanks to Steffen Goeldner.
Added $dbh->foreign_key_info(...) thanks to Steffen Goeldner.
Added $dbh->quote_identifier(...) insipred by Simon Oliver.
Added $dbh->set_err(...) for DBD authors and DBI subclasses
(actually been there for a while, now expanded and documented).
Added $h->{HandleError} = sub { ... } addition and/or alternative
to RaiseError/PrintError. See the docs for more info.
Added $h->{TraceLevel} = N attribute to set/get trace level of handle
thus can set trace level via an (eg externally specified) DSN
using the embedded attribute syntax:
$dsn = 'dbi:DB2(PrintError=1,TraceLevel=2):dbname';
Plus, you can also now do: local($h->{TraceLevel}) = N;
(but that leaks a little memory in some versions of perl).
Added some call tree information to trace output if trace level >= 3
With thanks to Graham Barr for the stack walking code.
Added experimental undocumented $dbh->preparse(), see t/preparse.t
With thanks to Scott T. Hildreth for much of the work.
Added Fowler/Noll/Vo hash type as an option to DBI::hash().
Documentation changes:
Added DBI::Changes so now you can "perldoc DBI::Changes", yeah!
Added selectrow_arrayref & selectrow_hashref docs thanks to Doug Wilson.
Added 'Standards Reference Information' section to docs to gather
together all references to relevant on-line standards.
Added link to poop.sourceforge.net into the docs thanks to Dave Rolsky.
Added link to hyperlinked BNF for SQL92 thanks to Jeff Zucker.
Added 'Subclassing the DBI' docs thanks to Stephen Clouse, and
then changed some of them to reflect the new approach to subclassing.
Added stronger wording to description of $h->{private_*} attributes.
Added docs for DBI::hash().
Driver API changes:
Now a COPY of the DBI->connect() attributes is passed to the driver
connect() method, so it can process and delete any elements it wants.
Deleting elements reduces/avoids the explicit
$dbh->{$_} = $attr->{$_} foreach keys %$attr;
that DBI->connect does after the driver connect() method returns.
As you can see, this is a major release.
Enjoy!
Tim.
