v2.12.4

Resolves a possible crash with SQLDescribeParam(). In Progress OpenEdge 11 driver setting the nullableptr argument to null causes a crash. This does not affect SQLite or MySQL drivers.

Thanks to @AndrewJD79 for finding and diagnosing the issue!

v2.12.3

Unicode: Resolves a major issue with BLOB datatype handling for BINARY and TEXT columns.

v2.12.2

Resolves a major issue with BLOB datatype handling for BINARY and TEXT columns.

v2.12.1

Resolves a Travis-CI build issue.

v2.12.0

Major work undertaken by Mateusz Łoskot provides new features and a host of bug fixes throughout. Refactoring work moves nanodbc away from platform dependent wchar_t in favor of char16_t or in the case of iODBC with unicode build enabled, char32_t. Boost.Test dropped in this version, in favor of Catch.

New Features

  • Converts usages of wstring and wchar_t to u16string and char16_t.
  • Enable iODBC + Unicode support with u32string types.
  • Add example program table_schema.cpp.
  • Add dbms_name() and dbms_version() methods to connection class.

Testing

  • Migrates tests from Boost.Test to Catch framework.
  • Enables unicode tests on travis-ci.
  • Syncs Dockerfile and Vagrantfile; adds quick usage docs for vagrant.
  • Switch Dockerfile over to ubuntu:precise (default).
  • Improve odbc_test.cpp to cope with DBMS variations.

Bug Fixes

  • Fix compiler warnings while building with VS2015.
  • Add missing optional schema_name parameter to usage info.
  • Workaround for VS2015 bug in std::codecvt for char16_t.
  • Fix retrieval of variable-length data in parts.
  • Fix catalog::columns::is_nullable() to handle valid NULL.
  • Fix check of total of characters required to display SQL_DATE.
  • Fix SELECT result sorting with NULL values involved.

v2.11.3

  • Fixes segmentation fault issue with unixODBC on Linux systems.
  • Adds support for while(!results.end()) style iteration.

v2.11.2

  • Adds this CHANGELOG.md file. Future releases should update it accordingly!
  • Adds CHANGELOG.md helper script.

v2.11.1

New Features

  • Major thanks again to Mateusz Łoskot for all the new features!
  • Adds convenient access to catalog objects (tables, columns, primary keys).
  • Adds database_name and catalog_name methods to connection class.
  • Adds CMake option NANODBC_ENABLE_LIBCXX to enable/disable libc++ builds.
  • Adds CMake option NANODBC_EXAMPLES to enable/disable the example target.
  • Adds a latest release branch to track most recent release.

Testing

  • Massive updates to Travis CI continuous integration.
  • Adds general odbc_test to target variety of ODBC drivers.
  • Adds specific MySQL tests.
  • Updates test target organization.
    • The way the targets were designed is such that:
      • test: runs all tests, but will not build them
      • tests: builds all tests, but does not run them
      • check: builds all tests and then runs all tests
    • For individual tests then, it makes sense to use:
      • ${name}_test: runs ${name}_test, but will not build it
      • ${name}_tests: builds ${name}_test, but does not run it
      • ${name}_check: builds ${name}_test and then runs it

Bug Fixes

  • Fix test check of result::affected_rows for SELECT statement.
  • Fix result::position to make it consistent with SQL_ATTR_ROW_NUMBER.
  • Fix string object construction syntax.
  • Adds missing #include <cstring>.

Other Changes

  • More robust and friendly publish and release scripts.
  • Updates to README and documentation.
  • Adds -DUNICODE and -D_UNICODE for Visual Studio projects.
  • Adds examples based on the documentation.
  • Adds rowset_iteration example.

v2.10.0

New Features

  • Adds Dockerfile to support testing and development.
  • Adds build.bat convenience script for Visual Studio users.
  • Adds CMake options NANODBC_INSTALL and NANODBC_TEST to control generation of those targets.

Bug Fixes

  • Fixes cmake build on OS X El Capitan.
  • Refine assert in result_impl::position with SQL_ROW_NUMBER_UNKNOWN.
  • MSBuild Platform property for 32-bit is Win32.
  • Reset null indicator before move for all columns, not just bound columns.
  • Fixes doxygen generation of macro docs.
