What i have tried Results wanted like this From One table , for each ID there can be multiple email id's based on some condition Ex
ID EmailID's
1 Mike.Foster@Mail.com
1 lilly.Foster@Mail.com
2 Michel.Josh@Mail.com
2 Nash.Ted@Mail.com
I have to get email Name from these Ids from another table, something like this
Output i Need
Email_Name
Foster.Mike,Foster.Lilly
Josh.Michel,Ted.Nash
This is what i tried.
SELECT User_Email =
STUFF((SELECT DISTINCT ', ' + User_Email
FROM table1 b
WHERE b.Component_ID= a.Component_ID
and [Role] ='Team Lead' and Functional_Group ='Product'
FOR XML PATH('')), 1, 2, '')
FROM [WFS].table1 a
GROUP BY table1
Now another table i want Email Names
Select EmailNamefrom Table2 where EmailIDs IN ( 'code for Email')
Table1 schema
ID Component_ID EmailIDs Role Functional_Group
1 1 Mike.Foster@Mail.com Team Lead Product
2 1 lilly.Foster@Mail.com Team Lead Product
3 2 Michel.Josh@Mail.com Team Lead Product
4 2 Nash.Ted@Mail.com Team Lead Product
Table 2 schema
ID EmailIDs EmailName
1 Mike.Foster@Mail.com Foster.Mike
2 lilly.Foster@Mail.com Foster.Lilly
Any suggestions are welcome.Thanks in advance
You were actually close but your SQL doesn't match your schema. This one works as you want:
SELECT Email_Name =
STUFF((SELECT DISTINCT ', ' + EmailIDs
FROM table1 b
WHERE b.Component_ID= a.Component_ID
and [Role] ='Team Lead' and Functional_Group ='Product'
FOR XML PATH('')), 1, 2, '')
FROM table1 a
GROUP BY a.Component_ID;
EDIT: I didn't understand what you are asking exactly. Might this be what you meant?
SELECT STUFF((SELECT ', ' + EmailName
FROM Table2 where EmailIDs IN ( SELECT EmailIDs
FROM table1
WHERE [Role] ='Team Lead' and Functional_Group ='Product')
FOR XML PATH('')), 1, 2, '')
Or you meant this:
SELECT DISTINCT Component_ID, emailNames
FROM table1
CROSS APPLY (SELECT STUFF((SELECT ', '+t2.EmailName
FROM table2 t2
INNER JOIN TABLE1 t1 ON t1.EmailIDs = t2.EmailIDs
WHERE t1.Component_ID = Table1.Component_ID
FOR XML PATH('')), 1, 2, '')
) t(EmailNames)
WHERE [Role] ='Team Lead' and Functional_Group ='Product'
Here is SQLFiddle Demo
Disregard this answer as I found out that GROUP_CONCAT()
is a MySQL specific function , which means it won't work in SQL Server, however, I'll let it stay for future references.
SELECT
GROUP_CONCAT(EmailName SEPARATOR ', ') as name
FROM
table1
INNER JOIN table2 ON table1.EmailIDs=table2.EmailIDs
WHERE
table1.EmailIDs=table2.EmailIDs
GROUP BY
table1.Component_ID
Output:
Foster.Mike, Foster.Lilly
Ted.Nash, Josh.Michel

You need CTE
with STUFF()
:
WITH t AS (
SELECT t1.*, t2.emailname
FROM table1 t1 INNER JOIN
table2 t2
ON t2.emailids = t1.emailids
)
SELECT id, STUFF ( (SELECT DISTINCT ','+t1.emailname
FROM t t1
WHERE t1.id = t.id
FOR XML PATH ('')
), 1, 1, ''
) AS Email_Name
FROM t
GROUP BY id;
