Question

I have a table with columns Name, EmailId, Process, Status like below.

**Input**

   Name       EmailId                Process      Status    
   apple1     [e-mail]       process1     Closed
   apple2     [e-mail]       process2     In Progress
   apple3     [e-mail]       process3     Complete      
   orange1    [e-mail]      process1     Closed
   orange2    [e-mail]      process2     Closed
   oran       [e-mail]      process3     Closed
   mango1     [e-mail]       process1     To Start

Now what I would like to have is the emailId and Status of people whose Status are closed for all the Process – Process1, process2, process 3

**Output**

EmailId              Status    
[e-mail]    Closed

Since all the process for orange have been closed I have the above row
Similarly I would like to have all the email ids of the table whose process are closed.

Another way:

SELECT 
    EmailId
FROM
    tableX AS t
GROUP BY 
    EmailId
HAVING
    COUNT( CASE WHEN Status <> 'Closed'
             THEN 1 
           END
         ) = 0 ;

or:

SELECT 
    t.EmailId
FROM
    ( SELECT DISTINCT EmailId
      FROM tableX 
    ) AS t
  LEFT JOIN
    tableX AS tt
      ON  tt.EmailId = t.EmailId
      AND tt.Status <> 'Closed'
WHERE
    tt.EmailId IS NULL ;
