JOIN Queries
The CData ADO.NET Provider for Apache HBase 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 Opportunity.Name, Account.Name FROM Account INNER JOIN Opportunity ON Account.Id = Opportunity.AccountId
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT Opportunity.Name, Account.Name FROM Account LEFT JOIN Opportunity ON Account.Id = Opportunity.AccountId
