MySQL Connector/C++ 2.0.3 m3 Development Release has been released

MySQL Connector/C++ 2.0.3 is the next development milestone of the MySQL Connector/C++ 2.0 series, and the first public release. Apart from covering more X DevAPI features, it adds a new, plain C API, called XAPI, that offers functionality similar to X DevAPI to applications written in plain C. Thus, not only can MySQL Connector/C++ be used to write C++ applications, as before.

Now, using the XAPI, MySQL Connector/C++ can be used to write plain C applications to access MySQL Database implementing a document store as well as execute traditional plain SQL statements. For more information about XAPI, refer to the documentation at

To learn more about how to write applications using the X DevAPI, see X DevAPI User Guide ( For more information about how to use Connector/C++ 2.0 and how the X DevAPI is implemented in it, see


The X DevAPI requires at least MySQL Server version 5.7.12 or higher with the X Plugin enabled. For general documentation about how to get started using MySQL as a document store, see Using MySQL as a Document Store (

X DevAPI Notes

New X DevAPI features added in this MySQL Connector/C++ release:

  • Methods for starting and controlling transactions
  • Using an X DevAPI URI or connection string to specify new session parameters
  • Capability of binding a session to the default shard and execute SQL statements there (using XSession.bindToDefaultShard())
  • Methods for counting elements in a table or collection
  • Access to multiple result sets if present in a query result
  • Methods to count items in a result set and fetch a complete result set at once (using fetchAll()), instead of accessing items one by one (using fetchOne())
  • Access to warnings reported when processing a statement (getWarnings())
  • Access to information about affected rows, generated auto-increment values, and identifiers of documents added to a collection
