How can I join together this querys sql server? - sql

Question

SQL FIDDLE DEMO HERE
I have this table structure for Workers table:
CREATE TABLE Workers
(
[Name] varchar(250),
[IdWorker] varchar(250),
[work] varchar(250)
);
INSERT INTO Workers ([Name], [IdWorker], [work])
values
('Sam', '001', 'Director'),
('Julianne', '002', 'Recepcionist'),
('Jose', '003', 'Recepcionist');
What I want is to get for each job the name of workers separate by commas, like this:
Director Recepcionist
------- ------------
Sam Julianne, Jose
I tried to used this query:
DECLARE #rec VARCHAR(MAX)
SELECT #rec = COALESCE(#rec + ', ', '') + Name from
Workers where job = 'Recepcionist' SELECT #dir AS Recepcionist
And I got this result:
Recepcionist
------------
Julianne, Jose
This works only for one job, but I need to add more, so I tried then to use this query:
SELECT [Director] , [Recepcionist]
FROM
(SELECT [job], [Name],RANK() OVER (PARTITION BY [job] ORDER BY [job],[Name]) as rnk
FROM Workers ) p
PIVOT(
Min([Name])
FOR [job] IN
( [Director] , [Recepcionist] )
) AS pvt
And I get this result:
Director Recepcionist
-------- ------------
Sam Julianne
Jose
I need to get the results in the same row separate by commas, how can I combine the two querys?
I accept suggestions, thanks.

Answer 1

I am assuming in your example query you meant job to reference the work column. The following query should do the job as per your sql fiddle.
SELECT STUFF(
(
SELECT ', ' + cast([Name] as varchar(max))
FROM Workers
WHERE [work] = 'Recepcionist'
FOR XML PATH('')
), 1, 2, ''
) AS Recepcionist
,STUFF(
(
SELECT ', ' + cast([Name] as varchar(max))
FROM Workers
WHERE [work] = 'Director'
FOR XML PATH('')
), 1, 2, '') AS Director;

Answer 2

the way you would do this using PIVOT would be like this.
SELECT *
FROM (SELECT [work],
STUFF((SELECT ', ' + [Name]
FROM Workers s
WHERE s.WORK = w.WORK
FOR XML PATH('')),
1, 2, '') AS [workers]
FROM Workers w) t
PIVOT (
MAX([workers])
FOR [work] IN ([Director], [Recepcionist])
) p
another alternative to PIVOT is MAX(CASE)
SELECT MAX(CASE WHEN [work] = 'Director' THEN [workers] END) AS [Director],
MAX(CASE WHEN [work] = 'Recepcionist' THEN [workers] END) AS [Recepcionist]
FROM (SELECT [work],
STUFF((SELECT ', ' + [Name]
FROM Workers s
WHERE s.WORK = w.WORK
FOR XML PATH('')),
1, 2, '') AS [workers]
FROM Workers w) t
both of these allow you to separate the data by other fields like Company or Department

Answer 3

you can do it like this
SELECT
t1.job
,STUFF(
(SELECT
', ' + t2.Name
FROM Workers t2
WHERE t1.job =t2.job
ORDER BY t2.Name
FOR XML PATH(''), TYPE
).value('.','varchar(max)')
,1,2, ''
) AS ChildValues
FROM Workers t1
GROUP BY t1.job
