Class ConnectionImpl

java.lang.Object
com.mysql.cj.jdbc.ConnectionImpl
All Implemented Interfaces:
JdbcConnection, MysqlConnection, Session.SessionEventListener, TransactionEventHandler, java.io.Serializable, java.lang.AutoCloseable, java.sql.Connection, java.sql.Wrapper
public class ConnectionImpl
extends java.lang.Object
implements JdbcConnection, Session.SessionEventListener, java.io.Serializable
A Connection represents a session with a specific database. Within the context of a Connection, SQL statements are executed and results are returned.

A Connection's database is able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, etc. This information is obtained with the getMetaData method.
