The IfxConnection interface is a subinterface of java.sql.Connection with Informix-specific methods added. The com.informix.jdbc.IfxDirectConnection class implements the com.informix.jdbc.IfxConnection interface. This interface provides a connection to the current database server from within a UDR. The connection corresponds to a server-query context and is passed to the UDR by the SQLJ language manager. The transaction context of this connection is that of the query issuing the UDR call, and the call to create a UDR connection does not specify any database or user information.
