Regardless of the method an application uses to connect to the Hybrid Data Pipeline connectivity service, certain properties are required to connect. Optional properties control behavior of the communication between the Hybrid Data Pipeline Driver forODBC and the Hybrid Data Pipeline connectivity service.
Connection properties can be supplied in a Data Source or .ini file or passed in a connection string using the Driver keyword. You can split them and specify some in a Data Source or .ini file and pass others in a connection string. The latter is common to protect credentials for security reasons.
