Want to fetch the data in the form of a table - sql

Question

I have written this query:
SELECT
d.DetailId,
i.ItemId,
d.fieldId,
d.Fieldvalue,
f.Name
FROM
EntityItemDetails d
inner join EntityItems i
on i.ItemId = d.ItemId
inner join Fields f
on f.Id = d.FieldId
WHERE
i.EntityId = 1
Output is:
DetailId ItemId FieldId FieldValue FieldName
1 1 9 Defect1 Name
2 1 10 abcdef Description
5 1 11 testing123 Status
I want result in this way:
Name Description Status
TestField abcdef testing123
Please suggest how to get this result by writing a query in sql.

Answer 1

What you want is called pivoting, and starting from SQL Server 2005, you can use a standard syntax for pivoting in Transact-SQL, with the help of the PIVOT clause.
Your query could be transformed for use with PIVOT like this:
WITH source AS (
/* this CTE is actually your original query */
SELECT
EntityItemDetails.DetailId,
EntityItems.ItemId,
EntityItemDetails.fieldId,
EntityItemDetails.Fieldvalue,
Fields.Name
FROM EntityItemDetails
INNER JOIN EntityItems ON EntityItems.ItemId = EntityItemDetails.ItemId
INNER JOIN Fields ON Fields.Id = EntityItemDetails.FieldId
WHERE EntityItems.EntityId = 1
)
SELECT
ItemId,
Name,
Description,
Status
FROM (
SELECT ItemId, FieldName, FieldValue
FROM source
) s
PIVOT (
MAX(FieldValue) FOR FieldName IN (
Name,
Description,
Status
/* add other possible names as necessary */
)
) p

Answer 2

SELECT
FieldValue,
[Name],
[Description],
[Status]
FROM
myTable -- OR (your posted query) myQuery
PIVOT
(
MIN(FieldValue)
FOR FieldName IN ([Name], [Description], [Status])
) AS myPivot;

Tahnk u so much Andriy M....
with very few changes I could get the desired result. Chenges are as below
WITH source AS (
/* this CTE is actually your original query */
SELECT EntityItemDetails.CreatedDate, EntityItems.EntityItemId,
EntityItemDetails.fieldId,
EntityItemDetails.Fieldvalue,
Fields.Name FieldName FROM EntityItemDetails
INNER JOIN EntityItems ON EntityItems.EntityItemId = EntityItemDetails.EntityItemId
INNER JOIN Fields ON Fields.Id = EntityItemDetails.FieldId WHERE EntityItems.EntityId = 1 and (FieldId=9 or FieldId=10 or FieldId=11) )
SELECT EntityItemId, [Name], [Description], [Status]
FROM ( SELECT EntityItemId, FieldName, FieldValue FROM source ) s
PIVOT ( MAX(FieldValue) FOR FieldName IN ( [Name], [Description], [Status] ) ) p
