title: WMB: In ESQL, is it possible to connect to a datasource defined as a JDBCProvider configurable service in lieu of ODBC DSN?
body: <p>I'm inheriting an existing WMB flow that is ESQL-centric (Compute nodes) that accesses its database via an ODBC DSN.  I'd prefer to use a configurable service for database access in lieu of an ODBC DSN, which is what I use with Java-centric flows (JavaCompute nodes). </p>
  
  <p>Is it possible to configure a Compute node to talk to a db via a configurable service?</p>
