These CMake options have been added to enable more fine-grained specification of installation directories. All are relative to
Previously, Connector/C++ binary distributions included a
BUILDINFO.txtfile that contained information about the build environment used to produce the distribution. Binary distributions now include a file named
INFO_BINthat provides similar information, and an
INFO_SRCfile that provides information about the product version and the source repository from which the distribution was produced. Source distributions include the
INFO_SRCfile only. (WL #12293)
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
-vs14suffix 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. (WL #12101)
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:
mysqlx_get_count()returns zero through the parameter and finishes with
mysqlx_store_result()does not return anything through the parameter (which remains unchanged) and finishes with
