MySQL Connectors. MySQL provides standards-based drivers for JDBC, ODBC, and .Net enabling developers to build database applications in their language of choice. In addition, a native C library allows developers to embed MySQL directly into their applications. getConnection establishes a database connection. This method requires a database URL, which varies depending on your DBMS. The following are some examples of database URLs: MySQL: jdbc:mysql://localhost:3306/ , where localhost is the name of the server hosting your database, and 3306 is the port number. Java. Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database.

As of Mule 3.5.0, the JDBC connector is deprecated, and has been replaced by the Database Connector. Previously it was simple to obtain a reference to a JDBC Connector using Java Code as follows: JdbcConnector jdbcConnector = (JdbcConnector) MuleServer.getMuleContext().getRegistry(). ActiveJDBC models when operate, utilize a connection found on a current thread. This connection is put on the local thread by Base or DB class before any DB operation. This approach allows for more concise API where there is no need for DB Session or persistent managers as in other Java ORMs. Here is a simple. The driver works like an adaptor which connects a generic interface to a specific database vendor implementation.
