JOIN Queries
The CData ADO.NET Provider for Jira supports standard SQL joins like the following examples.
Inner Join
An inner join selects only rows from both tables that match the join condition:
SELECT Projects.LeadName, Issues.Summary FROM Projects, Issues WHERE Projects.Id=Issues.ProjectId
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT Projects.LeadName, Issues.Summary FROM Projects LEFT OUTER JOIN Issues ON Projects.Id=Issues.ProjectId
