Use values of jira fields in the query (database values plugin)

[Olga Mendscheritski]

I use the database values plugin to retrieve some additional information about the customer based on the reporter. There is a following example in the documentation:

sql.query=select id, firstname, lastname, city, country from customer where jira_key like '${jira.project.key}'

It seems like only jira.project.key or jira.user will be substituted with real values. Can I access another field values in the query?

Thank you very much!

No other values are possible.
