             Summary: Document enums usage in SQL queries
                 Key: IGNITE-5347
                 URL: https://issues.apache.org/jira/browse/IGNITE-5347
             Project: Ignite
          Issue Type: Sub-task
            Reporter: Denis Magda
            Assignee: Denis Magda
             Fix For: 2.1


Here is a documentation to be added to this page 
(https://apacheignite.readme.io/v2.0/docs/distributed-queries-21):

If a field is of a Java enum type, then you can pass the field's value as a 
parameter via standard `?` keyword or use enum's literal or ordinal value 
directly, as shown in the example below:

// SQL query with the field of Java enum type.
SqlFieldsQuery sql = new SqlFieldsQuery(
"SELECT name FROM Person WHERE role = 'DEVELOPER' or role = 2");
