What is a MySQL Connector?
MySQL offers standard database driver connectivity for using MySQL with applications and tools that are
compatible with industry standards ODBC and JDBC. Any system that works with ODBC or JDBC can use MySQL.
Connector/ODBC
Standardized database driver for Windows, Linux, Mac OS X, and Unix platforms.
Connector/Net
Standardized database driver for .NET platforms and development.
Connector/J
Standardized database driver for Java platforms and development.
Connector/Python
Standardized database driver for Python platforms and development.
Connector/C++
Standardized database driver for C++ development.
Connector/C (libmysqlclient)
A client library for C development.
MySQL native driver for PHP - mysqlnd
The MySQL native driver for PHP is an additional, alternative way to connect from PHP 5.3 or newer to the
MySQL Server 4.1 or newer.

What Is Connector/Net
• Core ADO.Net compatible data provider
• Connection pooling
• SSL and Windows authentication support
• Mono compatible*
• Entity Framework provider
• ASP.Net web providers
• Membership, role, profile, session providers
• Visual Studio Integration
• Visual Studio 2005, 2008, & 2010
• Intellisense and syntax coloring

8. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
What is MySQL Connector/J?
• Pure Java/JDBC client for MySQL
• Not dependant on any C/C++ libraries like many early JDBC drivers did. Pretty
much expected nowadays.
• Supports advanced SSL, load-balancing, plug-ins
• Various configuration options for SSL including client-side authorization (to the
server), cipher suite selection, etc. SSL is becoming more important and we
should have even more stuff coming. Support for the latest JDK security
features.
• Support for scaling and HA config including load-balancing, replication, failover
and Fabric.

9. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
What is MySQL Connector/J?
• Highly configurable performance tuning and behavioral options
• You can look at the docs for a complete list:
http://dev.mysql.com/doc/connector-j/en/connector-j-reference-
configuration-properties.html
• Lots of low-level performance tuning options, behavioral options for app-
specific convenience or certain app servers/frameworks. Lots of stuff to
support many different environments and new stuff being added constantly.
• Fits in any application being embeddable to large-scale app servers like
WebLogic & JBoss

Latest releases
• MySQL Connector/Net 6.7.9, 6.8.7, 6.9.8
• Supports for .NET 3.5 – 4.5
• Available for download at dev.mysql.com
• MySQL server support starting with 5.1 to 5.7.9 versions.
• Support for Entity Framework versions
• MySQL Fabric support
• Replication with MySQL server

12. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. | 12
Replication and Load Balancing support
• Allows to connect to master/slaves environments
• Load balancing requests over all the available servers.
• Read-only queries use a load balancing behavior.
• DML queries (insert, update, delete, etc.) are sent to the master server.
• Round Robin distribution is used in Connector/NET for Load Balancing.
• Failover support: Connector/NET monitors connections to the servers,
redirecting load to available servers on each request. When a server
is back online is marked available again.

13. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. | 13
Security guidelines
• SSL usage is enforced when Connector/net is used with MySQL Server 5.7.9

Table Caching
Overview
• Supports TableDirect command types only
• Does not cause a round trip to the server
• Will be extensible in the future
– Think about memached/velocity
• Is enabled at the command level
• Does not work with SequentialAccess
• XXXX% faster than straight queries

16. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
Table Caching
How do I use it?
It's really easy to use it in a reader
MySqlCommand cmd = new MySqlCommand(“zipcodes”, connection);
cmd.EnableCaching = true;
cmd.ExecuteReader();
Or use that command in a data adapter
MySqlDataAdapter da = new MySqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(dt);

17. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
Windows Authentication
Features and requirements
• Supports local and domain authentication
• Requires MySQL Server 5.5 or higher (commercial)
• Supports the Integrated Security keyword
• Server supports user mapping
• User/groups
• Supports proxies
• This is NOT a full tutorial on pluggable authentication!
• Client side plugin shipped with server is not used.
• Please see http://dev.mysql.com/doc/refman/5.5/en/windows-
authentication-plugin.html

18. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
Milliseconds support
• MySQL Server 5.6.4 and up introduced Fractional Seconds support in
DateTime, Time and TimeStamp type columns with up to 6 precision digits.
• Connector/Net can manage up to 6 also when using MySqlDateTime types to
read/write values for columns of the previous mentioned types.
• This support doesn’t affect the current behavior when using DateTime, Time
and TimeStamp with Connector/Net and any other MySQL server version.

19. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
• In the previous code If the connection string used after the security
definition does not match all the requirements, the attempt to do the
connection will throw a SecurityException before even attempting the
connection to the specified database.
• The MySqlClientPermission instance can have multiple connections
and any call to MySqlConnection.Open will not succeed if the
connection string fails at any of the specified parameters or values.
Partial Trust Support…

21. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
Latest developments in MySQL Connector/J
• Support for JDBC 4.2 spec
• Support the new date/time types in Java 8. This is a "nice to have" feature for
many.
• Support for MySQL Fabric
• Notes: We support all Fabric features including authentication, HA & sharding.
• Ongoing TLS/security enhancements with better default security for MySQL
5.7

22. Copyright © 2015 Oracle and/or its affiliates. All rights reserved. |
Latest developments in MySQL Connector/J
SSL used by default when connecting to Enterprise 5.7 servers which auto-
generate SSL key pairs. The server has recently raised some of their hard-coded
security minimums and we are fully supporting these too.
Support for SHA-256 authentication vs SSL/TLS or RSA encrypted passwords.
Performance improvements including community contributions.
We've made a number of small but appreciated performance improvements
found by community members. We've also accepted a few small patches for
performance improvements from community members.

• Multi-host connections
• MySQL Fabric
• Fabric use cases range from basic HA (master/slave) setups for improved
manageability to large-scale setups with sharding over many master/slave
clusters. Fabric is releasing multi-node support at OOW which addresses the
SPOF factor. C/J has great support for Fabric.
• Load-balancing / Replication
• Provision of JMX (built-in Java management console) access to connection
pools allowing to perform failover and add/remove slaves at runtime.
• Replication support also supports the new multi-master configuration
required for group replication.
