The CData Cmdlets PowerShell Module 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
