profile data, and the accompanying INFORMATION_SCHEMA.PROFILING table.
* Added the Uptime_since_flush_status status variable, which indicates the
number of seconds since the most recent FLUSH STATUS statement.
* Incompatible change in DATE_FORMAT().

its type and possible values.
* The bundled yaSSL library was upgraded to version 1.5.8.
* The --skip-thread-priority option now is enabled by default for binary Mac
OS X distributions. Use of thread priorities degrades performance on Mac OS X.
* Added the --disable-grant-options option to configure.
* Bug fixes.

1.47 Sun Mar 4 03:30:00 UTC 2007
* Do the search in unions only when we must do them, not on every
call to the Next method
* Don't index ex/ dir to avoid complains by the indexer of PAUSE/CPAN
1.46 Sun Feb 25 19:04:00 UTC 2007
* when doing a union, we need to actually search, rather than just
doing a count
* add support for testing with Oracle backend
* Use CROSS JOIN instead of ',' as SQL parsers in Pg and some mysql
are buggy and cannot parse "FROM X, Y JOIN Z ON Z.f = X.f"
* deprecate DEBUG method, it's still there but produce warning
* fix CleanSlate method that was missing several keys
* fix a long standing bug we had, we didn't write depends_on data about
a join, so we could build queries with incorrect parens around join
conditions
* fix default values for ALIAS1 argument in the Join method, istead of
defaulting FIELD1 to 'main' value
* fix a TODO test
* internal refactoring of a storage for query's conditions,
instead of building query strings right after the limit
or join, we now build a perl structure
* don't clone attributes that don't exists in the Clone method
* we use Encode module without perl version check for a long time, so
we can get rid of all checks for the version and load the module
at compile time everywhere we need it
* implement MayBeNull method in the handler that checks if applied
conditions allow NULLs in the result set
* implement cascaded LEFT JOINs optimization
* additional tests for CleanSlate and Clone methods, ENTRY_AGGREGATOR
argument, different types of joins and LEFT JOIN optimizer
* bindings/python/Makefile.am: libtool builds shared libraries
anyway, no need for extra LDFLAGS that bite non GNU ld versions
* src/rrd_tool.c: resolve snprintf overflow warning by using sizeof
Changes in DBD-Oracle 1.19 (svn rev 8002) 3rd November 2006

Changes in DBD-Oracle 1.18 (svn rev 6697)

Added auto-detection of ORACLE_HOME in some configurations.
Changes in DBD-Oracle 1.16 (svn rev 515) 22nd October 2004
NOTE:
This release has major changes to Unicode support. See below.
It no longer supports the old Oracle 7 OCI interface.
It requires DBI >= 1.38 for some of the tests if using Perl 5.6.
It no longer supports Perl 5.5 or earlier.
Fixed placeholder names to be case insensitive thanks to Charles Jardine.
Fixed some LOB test problems with Oracle 8.1.7 by implementing ora_lob_append
with OCILobGetLength() and OCILobWrite(), instead of buggy OCILobWriteAppend(),
if the Oracle client version is < 9.0. Thanks to Jeff Urlwin.
Fixed handling of temporary LOBs thanks to Chris Donnelly.
Fixed memory leaks in auto LOB refetch code thanks to Dongqiang Bai.
Fixed reporting of length truncated in error message thanks to Jeff Urlwin.
Fixed column_info() to handle TIMESTAMP and INTERVAL datatypes
for Oracle >= 8 thanks to Stephen Clouse.
Fixed STORE to cache attribute value in handle cache.

Fixed truncation error fetching very small numbers (1 ^ -130).
Fixed Oraperl to not enable PrintError or AutoCommit (broken since 1.13).
Changed some utf8 internals for LOBs.
Changed ORA_OCI constant from being just 7 or 8 to being a dualvar:
in numeric context returns the major.minor version number (8.1, 9.2 etc)
in string context it returns the full "major.minor.foo.bar" version string.
Changed some SUCCESS_WITH_INFO situtions to be treated as a "warning"
by setting $DBI::err to "0" (and so trigger PrintWarn in DBI >= 1.43)
eg "ORA-28011: the account will expire soon; change your password now"
and package compilation errors.
Added automatic support for UTF-8 for both NLS_LANG and NLS_NCHAR
Many thanks to Lincoln Baxter who did most of the hard work and testing
and to Jeff Urlwin and others who also helped out.
Perl 5.8.x and Oracle 9+ are highly recommended if you want to use Unicode.
See POD for more information and documentation.
Added support for "... RETURNING lob_locator_column INTO ?"
using $sth->bind_param_inout(2, \$loc, 0, {ora_type => ORA_BLOB});
Added bind_param() ora_csform, ora_csid, and ora_maxdata_size attributes.
Added bind_param() support for SQL_BLOB & SQL_CLOB thanks to Stephen Clouse.
Added $dbh->ora_can_unicode and $dbh->ora_nls_parameters thanks to Andy Hassall.
Changes in DBD-Oracle 1.15 27th January 2004
NOTE: DBD::Oracle now requires DBI version 1.28 (June 2002) or later.
NOTE: This is probably the last release that will support being
built with the old Oracle 7 OCI interface.
Fixed for extproc_perl (http://search.cpan.org/author/JHORWITZ/extproc_perl/)
Fixed Oraperl handling of ora_errno and ora_errstr thanks to Martin Busik.
Fixed PRECISION for "NUMBER" to be 126 not 0 thanks to Steffen Goeldner.
Fixed bind_param_inout() for placeholders not assigned to in PL/SQL.
Changed bind_param_inout for CHAR types to no longer use a minimum
length of 28 characters. Warning: this change may break code that
doesn't pass bind_param_inout() a length value large enough for the
returned string. (The minimum length was not documented and should
not have been relied upon. This change currently only applies to the
CHAR type but may extended to all string types in a later release.)
Changed type_info_all() to return the same type info as Oracle's own
ODBC driver does, thanks to Andy Hassall for the data.
The types include LOBs but not the new TIMESTAMP and INTERVAL types.
Added direct access to LOB Locators and major LOB Locator functions
such as $sth->ora_lob_read(...), $sth->ora_lob_write(...) etc.
This work was sponsored by Geospiza Inc.

Added docs for returning a recordset (table/array) using Oracle >=9.0.1
via "FUNCTION foo RETURN type PIPELINED" thanks to Steve Baldwin.
Added docs on ora_check_sql=>0 in prepare() to avoid server-side parses.
Added support for sharing database connections with ProC/SQLLIB code
via ora_use_proc_connection attribute, thanks to Kristian Nielsen
needs build time option thanks to Steffen Goeldner
Added (restored) the error "possibly near <*> indicator" marker for
syntax errors thanks to Jason Hitt and Andy Hassall.
Added $dbh->{ora_parse_error_offset} attribute thanks to Andy Hassall.
Added auto setting of $dbh->{Username} if not given to connect
i.e. using Oracle OS authentication and connecting as "/"
by selecting SYS_CONTEXT('userenv','session_user') from the db
thanks to Eric Lenio and Andy Hassall.
Changes:
* Pass a range in :conditions to use the SQL BETWEEN operator. #6974
[dcmanges] Student.find(:all, :conditions => { :grade => 9..12 })
* Don't create instance writer methods for class attributes. [Rick]
* When dealing with SQLite3, use the table_info pragma helper, so that the
bindings can do some translation for when sqlite3 breaks incompatibly
between point releases. [Jamis Buck]
* SQLServer: don't choke on strings containing 'null'. #7083 [Jakob S]
* Consistently use LOWER() for uniqueness validations (rather than mixing with
UPPER()) so the database can always use a functional index on the lowercased
column. #6495 [Si]
* MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last
inserted id. #6778 [Jonathan Viney, timc]
* Fixtures use the table name and connection from set_fixture_class. #7330
[Anthony Eden]
* SQLServer: quote table name in indexes query. #2928 [keithm@infused.org]

DBD::PgPP is a Pure Perl client interface for the PostgreSQL database.
This module implements network protocol between server and client of
PostgreSQL, thus you don't need external PostgreSQL client library like
libpq for this module to work. It means this module enables
you to connect to PostgreSQL server from some operation systems
which PostgreSQL is not ported. How nifty!
