The most recent Stable (GA) release of MariaDB Connector/C++ is:MariaDB Connector/C++ 1.1.6

MariaDB Connector/C++ is the interface between C++ applications and MariaDB Server. MariaDB Connector/C++ enables development of C++ applications using a JDBC-based API, which is also used by MariaDB Connector/J. This is the first release candidate (RC) release of MariaDB Connector/C++ 1.1.

MariaDB Connector/C++ 1.1.2 was released on 2022-11-30. This release is of Release Candidate (RC) maturity, and should not be used with production workloads.

MariaDB Connector/C++ in its current implementation uses the MariaDB protocol via the MariaDB Connector/C API. Connector/C 3.3.0 is used in this release.

Notable Changes

• Added macOS PKG packages.

• Added support of two optimized modes of executeBatch/executeLargeBatch PreparedStatement methods execution: ()

  • rewriteBatchedStatements connection option

rewriteBatchedStatements

• When using the rewriteBatchedStatements connection option, for INSERT queries the connector will construct a single query using batch parameter sets. For example:

will be rewritten as:

If the query cannot be rewritten in multi-values, the rewriteBatchedStatements connection option will use multi-queries. For example:

will be rewritten as:

• If the rewriteBatchedStatements connection option is selected, the useServerPrepStmts option is set to false.

• If both rewriteBatchedStatements and useBulkStmts options are selected, rewriteBatchedStatements takes precedence.

useBulkStmts

• The useBulkStmts connection option uses the MariaDB bulk execution feature, so it requires MariaDB Server 10.2.7 or later. useBulkStmts will be used even if useServerPrepStmts is not set, in other words, if the default statement prepare method is client-side prepare.

• If both useBulkStmts and rewriteBatchedStatements options are selected, rewriteBatchedStatements takes precedence.

Issues Fixed

• Attempting connections from multiple threads causes the connector to crash. ()

• PreparedStatement setDouble only processes the first 6 significant digits and zeros any additional digits. ()

• Result-set streaming is not supported in this release series, but setting setFetchSize does not throw an exception and can cause the application to crash.

Installation

The most recent Stable (GA) release of MariaDB Connector/C++ is:MariaDB Connector/C++ 1.1.6

MariaDB Connector/C++ is the interface between C++ applications and MariaDB Server. MariaDB Connector/C++ enables development of C++ applications using a JDBC-based API, which is also used by MariaDB Connector/J.

MariaDB Connector/C++ 1.1.0 was released on 2021-08-06. This release is of Beta maturity, and should not be used with production workloads.

MariaDB Connector/C++ implements the MySQL protocol using the MariaDB Connector/C API. This release depends on Connector/C 3.2.3.

Notable Changes

• The default connection character set is utf8mb4. ()

• Re-execution or destruction on any type of statement object closes all of its result-sets. ()

• ResultSet streaming is supported. The defaultFetchSize connection option sets the default number of rows in a result-sets retrieved at a time. The setFetchSize statement method sets number of rows for the statement. ()

Notable API Changes

• ResultSet get methods are const ()

• sql::Properties class passed to connect methods is a class defined in the library. DatabaseMetaData::getTables accepts the sql::List class object. Methods still accept std::map and std::list objects. ()

MariaDB Connector/C++ is the interface between C++ applications and MariaDB Server. MariaDB Connector/C++ enables development of C++ applications using a JDBC-based API, which is also used by MariaDB Connector/J. This is the second Beta release of MariaDB Connector/C++.

MariaDB Connector/C++ in its current implementation uses the MariaDB protocol via the MariaDB Connector/C API. Connector/C 3.3.0 is used in this release.

Notable Changes

• MariaDB Connector/C++ 1.1.1 adds the ability to create a connection pool to improve usage of resources and to provide a faster way to connect to the server. ()

  • The new class MariaDbDataSource has been added to enable creating a connection pool. The pool is created when MariaDbDataSource::getConnection is called the first time. Example:

• Default for option useResetConnection has been changed from false to true. The change of default to true means the Connection::reset() method issues a connection reset command at the server by default. Previous default value of false meant Connection::reset() did a "soft reset" and set only certain system variables and connection parameters according to the connection properties.

• New connection properties have been added to configure the pool:

• New node failover support. () An application can supply more than one host to use for connection. An individual port number can be specified for each host:

MariaDB Connector/C++ 1.1 will always try to connect to the first host in the list. Other hosts in the list will be used if a tried host cannot be reached.

• LOAD DATA LOCAL INFILE is not allowed by default. It can be switched on by using the allowLocalInfile property. (), ()

MariaDB Connector/C++ in its current implementation uses the MariaDB protocol via the MariaDB Connector/C API. Connector/C 3.3.10 is used in this release.

Notable Changes

• The false or nullptr value used for boolean connection property initialization is now treated as false. It used to end up as true because SQLString makes an empty string out of nullptr, which is rendered true for the connection property. This fix introduced a 3rd state for the SQLString, NULL, and makes such a string as a value option to be treated as false. However, the NULL string will still have an empty string value in different string operations. Setting or changing its value does not make the string NULL. This "Nulliness" is still intended mainly for the driver's internal use and is designed to not change anything for applications. Though when exposed to application comparison operators, such as == and !=, they will consider the NULL state of the SQLString object if compared with nullptr. ()

Bugs Fixed

• Newly introduced and referenced header files were missing in the MSI package ()

MariaDB Connector/C++ implements the MySQL protocol using the MariaDB Connector/C API. This release depends on MariaDB Connector/C 3.3.14.

Notable Changes

• - The Driver now always cache all binary results to avoid access violation error while using result-set created with server prepared statements after the connection object has been closed. In case result-set streaming is used results naturally are not cached, but operations on the result-set after statement/connection is closed will cause SQLException to be thrown that the result-set is closed because of that

• - reconnect and reset methods in the Connection interface are deprecated

• - if trustServerCertificate is true(this is default) the connector will explicitly disable certificate verification. This enables work of the connector with Connector/C v.3.4 for unencrypted connection on the platforms there Connector/C is linked dynamically. Setting the option to

Bugs Fixed

• - Removed volatile deprecation build warnings

• - With default settings the driver uses slowest possible batch executing method

• - Inconsistent types naming of the names returned by ResultSetMetaData::getColumnTypeName()

• - Introduced initSql connection option permitting application to set a single query or the semi-colon separated list of SQL queries to be executed at the connection time

Bugs Fixed

• - Empty stream should result in empty DB value, not a NULL

• - Possible issues in getImportedKeys, getExportedKeys and getCrossReference with 12.1 server
