[odb-announcements] ODB 2.4.0 released

Wed Feb 11 06:59:41 EST 2015

Hi,
We have released ODB 2.4.0. The NEWS file entries for this release are
as follows:
 * Support for bulk operations in Oracle and SQL Server. Bulk operations
   persist, update, or erase a range of objects using a single database
   statement execution which often translates to a significantly better
   performance. For details, refer to Section 15.3, "Bulk Database
   Operations" in the ODB manual.
 * Support for object loading views. Object loading views allow loading of
   one or more complete objects instead of, or in addition to, a subset of
   data members and with a single SELECT statement execution. For details,
   refer to Section 10.2, "Object Loading Views" in the ODB manual.
 * New database class functions, query_one() and query_value(), provide
   convenient shortcuts for situations where the query is known to return
   at most one element (query_one) or exactly one element (query_value).
   Corresponding execute_one() and execute_value() functions for prepared
   queries are also provided. For details, refer to Sections 4.3, "Executing
   a Query" and 4.5, "Prepared Queries" in the ODB manual.
 * Support for defining persistent objects as instantiations of C++ class
   templates, similar to composite value types. For details, refer to
   Section 15.2, "Persistent Class Template Instantiations" in the ODB
   manual.
 * Support for object and table join types in views. Supported join type
   are left, right, full, inner, and cross with left being the default.
   For details, refer to Sections 10.1, "Object Views" and 10.3, "Table
   Views" in the ODB manual.
 * Support for result modifiers in view query conditions. Currently
   supported result modifiers are 'distinct' (which is translated to
   SELECT DISTINCT) and 'for_update' (which is translated to FOR UPDATE or
   equivalent for database systems that support it). For details, refer to
   Section 10.5, "View Query Conditions" in the ODB manual.
 * Support for persisting std::deque containers.
 * New pragma, on_delete, allows the specification of an on-delete semantics
   (translated to the ON DELETE SQL clause) for an object pointer. For more
   information, refer to Section 14.4.15, "on_delete" in the ODB manual.
 * Besides odb::stderr_tracer there is now odb::stderr_full_tracer that
   traces statement preparations and deallocations in addition to their
   executions. This new implementation can be useful when you want to see
   the text of a statement that contains a syntax error and therefore
   will not actually be executed. For more information, refer to Section
   3.13, "Tracing SQL Statement Execution" in the ODB manual.
 * ODB can now compile headers that use #pragma once instead of include
   guards.
 * User-supplied prologues and epilogues are now generated outside the
   pre.hxx/post.hxx includes. This allows the use of precompiled headers
   with the generated files.
 * Support for calling MySQL stored procedures. For details and limitations
   refer to Section 17.7, "MySQL Stored Procedures" in the ODB manual.
 * Support for calling SQL Server stored procedures. For details and
   limitations refer to Section 21.7, "SQL Server Stored Procedures" in
   the ODB manual.
 * New option, --oracle-warn-truncation, makes ODB warn about SQL names
   that are longer than 30 characters and are therefore truncated. ODB
   now also detects when such truncations lead to Oracle name conflicts
   and issues diagnostics even without this option specified.
 * For MySQL, PostgreSQL, and SQL Server, ODB now warns when an SQL name
   exceeds the database limit (64, 63, and 128 characters, respectively).
   SQLite has no limitation on name lengths. For Oracle, which has a limit
   that is much more likely to be reached in normal circumstances (30
   characters), a more comprehensive detection is implemented (see the item
   above).
 * New option, --statement-regex, can be used to process prepared statement
   names that are used by PostgreSQL. This can be useful, for example, to
   shorten names that exceed the PostgreSQL name limit.
 * The --std option now accepts the 'c++14' value.
This release also adds support for Visual Studio 2013 (VC++ 12.0), including
project/solution files for all the runtimes, tests, and examples.
We have also upgraded the private copy of GCC that is used by the ODB
compiler binary packages to 4.9.2 (actually, 4.9.3 pre-release) on all
the platforms except Solaris (there it remains at 4.7.3). In particular,
this should make a difference to projects wishing to use more C++11/C++14
features.
A more detailed discussion of the major new features can be found in the
following blog post:

architecture/library combinations. Specifically:

We would also like to thank everyone who reported bugs, suggested fixes
or new features, as well as tested early versions of this release. In
particular, a big thanks goes to Dave Johansen who is maintaining ODB
packages for RHEL/CentOS and Timo Rothenpieler who is doing the same
for Gentoo. If you are packaging ODB for another distribution, please
speak up so that I can announce/acknowledge your work.
If you plan to use ODB on Mac OS X or MinGW/MinGW64, there are new
