Dear MySQL users,
MySQL Connector/C++ 8.0.14 is a new release version of the MySQL Connector/C++ 8.0 series.
Connector/C++ 8.0 can be used to access MySQL implementing Document Store or in a traditional way, using SQL queries. It allows writing both C++ and plain C applications using X DevAPI and X DevAPI for C. It also supports the legacy API of Connector/C++ 1.1 based on JDBC4.
To learn more about how to write applications using X DevAPI, see “X DevAPI User Guide” at
See also “X DevAPI Reference” at
and “X DevAPI for C Reference” at
For generic information on using Connector/C++ 8.0, see
For general documentation about how to get started using MySQL as a document store, see
To download MySQL Connector/C++ 8.0.14, see the “Generally Available (GA) Releases” tab at
Changes in MySQL Connector/C++ 8.0.14 (2019-01-14) * Packaging Notes * X DevAPI Notes Configuration Notes * These CMake options have been added to enable more fine-grained specification of installation directories. All are relative to CMAKE_INSTALL_PREFIX: + CMAKE_INSTALL_LIBDIR: Library installation directory. + CMAKE_INSTALL_INCLUDEDIR: Header file installation directory. + CMAKE_INSTALL_DOCDIR: Documentation installation directory. (Bug #28045358) Packaging Notes * Previously, MySQL Connector/C++ binary distributions included a BUILDINFO.txt file that contained information about the build environment used to produce the distribution. Binary distributions now include a file named INFO_BIN that provides similar information, and an INFO_SRC file that provides information about the product version and the source repository from which the distribution was produced. Source distributions include the INFO_SRC file only. * MySQL Connector/C++ now is compatible with MSVC 2017, while retaining compatibility with MSVC 2015: + Previously, Connector/C++ binary distributions were compatible with projects built using MSVC 2015. Binary distributions now are compatible with projects built using MSVC 2017 or 2015. DLLs have a -vs14 suffix in their names to reflect that they are compatible with MSVC 2015, but can also be used in MSVC 2017 projects. + Previously, Connector/C++ source distributions could be built using MSVC 2015. Source distributions now can be built using MSVC 2017 or 2015. + Previously, the MSI installer accepted the Visual C++ Redistributable for Visual Studio 2015. The MSI installer now accepts the Visual C++ Redistributable for Visual Studio 2017 or 2015. * Installers for Connector/C++ are now available as Debian packages. See Installing Connector/C++ from a Binary Distribution (http://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-binary.html). X DevAPI Notes * Connector/C++ now provides collection counting methods for applications that use X DevAPI for C: + mysqlx_collection_count(): The number of documents in a collection without filtering. mysqlx_collection_t *c1 = mysqlx_get_collection(schema, "c1", 1); ulong64_t documents; mysqlx_collection_count(c1, &documents); + mysqlx_table_count(): The number of rows in a table without filtering. mysqlx_table_t *t1 = mysqlx_get_table(schema, "t1", 1); ulong64_t rows; mysqlx_table_count(t1, &rows); + mysqlx_get_count(): The number of remaining cached rows held at the moment. After a row is consumed by a fetch function, the number of cached rows decreases. mysqlx_stmt_t *stmt = mysqlx_sql_new(session, query, strlen(query)); mysqlx_result_t *res = mysqlx_execute(stmt); ulong64_t row_count; mysqlx_get_count(res, &row_count); mysqlx_get_count() is similar in all respects to mysqlx_store_result() except that the behavior differs after fetching rows when reaching zero number of rows in the cache: o mysqlx_get_count() returns zero through the parameter and finishes with RESULT_OK. o mysqlx_store_result() does not return anything through the parameter (which remains unchanged) and finishes with RESULT_ERROR.
Enjoy and thanks for the support!
