I have a table with the following results (from an SQL Query)
ID | Type | Comment |
---|---|---|
12345 | Manager Comment | This is a Manager comment |
12345 | HR Comment | This is a HR comment |
12345 | HR Comment | This is another HR comment |
54321 | Manager Comment | This is a Manager comment |
54321 | Manager Comment | This is another Manager comment |
54321 | Manager Comment | This is another Manager comment aswell |
I'm tryring to get the output to look like this:
ID | Manager Comment 1 | Manager Comment 2 | Manager Comment 3 | HR Comment 1 | HR Comment 2 |
---|---|---|---|---|---|
12345 | This is a HR comment | This is a HR comment | This is another HR Comment | ||
54321 | This is a Manager comment | This is another Manager comment | This is another Manager comment aswell |
This number of comments can be variable between 0 and 5.
I've tried the following but it only works on the newest comments in each section:
SELECT *
FROM
(
SELECT
A.[SHIFTASSIGNID] as 'ID'
,c.[COMMENTTEXT] as 'Comment Type'
,b.COMNTNOTETXT as 'Comment'
FROM [tkcsdb].[dbo].[SHFTASGNCOMNTMM] A
join [tkcsdb].[dbo].[COMNTNOTEDTL] B on
a.[COMNTNOTEID] = b.[COMNTNOTEID]
join [tkcsdb].[dbo].[COMMENTS] C
on c.commentID = a.commentID
where A.SHIFTASSIGNID = 7354246
) AS SourceTable PIVOT(max([Comment]) FOR [Type] IN([HR Notes],[Manager Notes], [Kommentar])) AS PivotTable;
Obviously it won't accomodate multipe comments, I've spent about 3 hours on this at the minute so any help would be much appreciated.
Thanks Chris
See a working sql-server example at the end. In the example I give comments a date so that they can be sorted accordingly.
What I'm doing:
I'm adding a row number to each comment text, so that Manager Comment
becomes Manager Comment 1
or Manager Comment 2
depending on the row number.
Then since we know we will have a max of five comments per type we can simply ask for all of them in the PIVOT
SELECT
*
FROM (
SELECT
A.[SHIFTASSIGNID] AS 'ID'
,C.[COMMENTTEXT] + ' ' + CONVERT(NVARCHAR(20), ROW_NUMBER() OVER (PARTITION BY A.[SHIFTASSIGNID], C.[COMMENTTEXT] ORDER BY (SELECT NULL))) AS 'Comment Type'
,B.COMNTNOTETXT AS 'Comment'
FROM [tkcsdb].[dbo].[SHFTASGNCOMNTMM] A
JOIN [tkcsdb].[dbo].[COMNTNOTEDTL] B
ON A.[COMNTNOTEID] = B.[COMNTNOTEID]
JOIN [tkcsdb].[dbo].[COMMENTS] C
ON C.commentID = A.commentID
WHERE
A.SHIFTASSIGNID = 7354246
) AS SourceTable PIVOT (MAX([Comment]) FOR [Comment Type] IN ([Manager Comment 1], [Manager Comment 2], [Manager Comment 3], [Manager Comment 4], [Manager Comment 5],
[HR Comment 1], [HR Comment 2], [HR Comment 3], [HR Comment 4], [HR Comment 5])) AS PivotTable;
Working Example:
SELECT
12345 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is a Manager comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date'
INTO #COMMENTS
UNION ALL
SELECT
12345 AS 'ID'
,'HR Comment' AS 'Type'
,'This is a HR comment' AS 'Comment'
,CONVERT(DATE, '2020-01-01') AS 'Date'
UNION ALL
SELECT
12345 AS 'ID'
,'HR Comment' AS 'Type'
,'This is another HR comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is a Manager comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is another Manager comment' AS 'Comment'
,CONVERT(DATE, '2020-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is another Manager comment aswell' AS 'Comment'
,CONVERT(DATE, '2019-01-01') AS 'Date';
SELECT
*
FROM (
SELECT
#COMMENTS.ID AS 'ID'
,#COMMENTS.type + ' ' + CONVERT(NVARCHAR(20), ROW_NUMBER() OVER (PARTITION BY #COMMENTS.ID, #COMMENTS.type ORDER BY #COMMENTS.DATE ASC)) AS 'Comment Type'
,#COMMENTS.Comment AS 'Comment'
FROM #COMMENTS
) AS SourceTable PIVOT (MAX([Comment]) FOR [Comment Type] IN ([Manager Comment 1], [Manager Comment 2], [Manager Comment 3], [Manager Comment 4], [Manager Comment 5],
[HR Comment 1], [HR Comment 2], [HR Comment 3], [HR Comment 4], [HR Comment 5])) AS PivotTable;
DROP TABLE #COMMENTS
My other answer will only work if you know or want to limit the number of comment columns. With this answer I demonstrate how you would do this for any number of comments.
In order to do this you must create your column headers dynamically and execute you PIVOT
query as a string using EXEC()
SELECT
12345 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is a Manager comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date' INTO Comments
UNION ALL
SELECT
12345 AS 'ID'
,'HR Comment' AS 'Type'
,'This is a HR comment' AS 'Comment'
,CONVERT(DATE, '2020-01-01') AS 'Date'
UNION ALL
SELECT
12345 AS 'ID'
,'HR Comment' AS 'Type'
,'This is another HR comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is a Manager comment' AS 'Comment'
,CONVERT(DATE, '2021-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is another Manager comment' AS 'Comment'
,CONVERT(DATE, '2020-01-01') AS 'Date'
UNION ALL
SELECT
54321 AS 'ID'
,'Manager Comment' AS 'Type'
,'This is another Manager comment aswell' AS 'Comment'
,CONVERT(DATE, '2019-01-01') AS 'Date';
