The JDBC Lookup query pipeline stage is used to call out to a database as part of a pipeline stage, to inject results into either the context/request or the pipeline document. For example, if you needed to look up a user from a DB and add their profile information onto a request for downstream use in a pipeline, the JDBC Lookup Stage would facilitate this.
You must first Upload a JDBC Driver to Fusion Server.
This stage supports asynchronous processing.

​
Example

An example of setup for a JDBC Lookup query pipeline stage. Upload stage config via POST to Fusion REST API endpoint api/query-stages/instances 
curl -u USERNAME:PASSWORD -X POST -H "Content-Type: application/json" -d '{"id": "jdbc-quer","type":"jdbc-query-lookup","driver":"postgresql-9.3-1101-jdbc4.jar","connection":"jdbc:postgresql:database","username":"user","password":"password1","preparedStatement":"select ID as id from DATABASE;"}' http://localhost:8764/api/query-stages/instances
Response 
{
  "type" : "jdbc-query-lookup",
