Question

I have a table Emaildistributionlist with 3 columns: UnitID which is unique, Email and dept Name. Here I write a query to get the list based on id,

SELECT distinct id, EMAIL 
FROM tblEmaildistributionlist  
WHERE dept like '%Contracts Dept%'

So I get an output like:

 ID=1  Email="[e-mail]" etc...

but the thing is one id has many email’s so I want a output like

ID=1 Email=[e-mail],[e-mail],[e-mail].` 

All emailid‘s in comma-separated form, in Email column.

What modification do I need in my query to get this result?

Answer 1

This work for Mysql

SELECT 
     id, 
     GROUP_CONCAT(distinct EMAIL SEPARATOR ',') as Email 
from 
     tblEmaildistributionlist 
WHERE 
     dept like '%Contracts Dept%' 
GROUP BY 
     id

This for SQL Server

SELECT
    a.id,
    STUFF((SELECT ','+b.Email From tblEmaildistributionlist b WHERE b.id=a.id AND b.dept like '%Contracts Dept%' FOR XML PATH ('')),1,1,'') as Email
FROM 
    tblEmaildistributionlist a
WHERE 
    a.dept like '%Contracts Dept%' 
GROUP BY
    a.id

And this is for Oracle 11g

SELECT 
     id, 
     LISTAGG(EMAIL, ',') as Email 
from 
     tblEmaildistributionlist 
WHERE 
     dept like '%Contracts Dept%' 
GROUP BY 
     id
