Question

CREATE TABLE TEMP (
DATE DATETIME
,category VARCHAR(3)
,amount MONEY
,NAMES VARCHAR(5)
)
INSERT INTO TEMP
VALUES (
'1/1/2012'
,'ABC'
,1000.00
,'john'
)
INSERT INTO TEMP
VALUES (
'2/1/2012'
,'DEF'
,500.00
,'amy'
)
INSERT INTO TEMP
VALUES (
'2/1/2012'
,'GHI'
,800.00
,'blue'
)
INSERT INTO TEMP
VALUES (
'2/10/2012'
,'DEF'
,700.00
,'ivy'
)
INSERT INTO TEMP
VALUES (
'3/1/2012'
,'ABC'
,1100.00
,'mark'
)
DECLARE #cols1 AS NVARCHAR(MAX)
,#cols2 AS NVARCHAR(MAX)
,#query AS NVARCHAR(MAX);
SET #cols1 = STUFF((
SELECT DISTINCT ',' + QUOTENAME(c.category)
FROM TEMP c
FOR XML PATH('')
,TYPE
).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
SET #cols2 = STUFF((
SELECT DISTINCT ',' + QUOTENAME(c.NAMES)
FROM TEMP c
FOR XML PATH('')
,TYPE
).value('.', 'NVARCHAR(MAX)'), 1, 1, '')
--select #cols
SET #query = 'SELECT date, ' + #cols1 + #cols2 + ' from
(
select date
, amount
, category
, names
from temp
) x
pivot
(
max(amount)
for category in (' + #cols1 + ')
) p
pivot
(
max(amount)
for names in (' + #cols2 + ')
) p
'
EXEC (#query)
Drop table temp
Below is the result I'm trying to get but I get an error Invalid column name 'amount'
ABC DEF GHI John Amy Blue Ivy Mark
1/1/2012 1000 NULL NULL 1000 NULL NULL NULL NULL
2/1/2012 NULL 500 NULL NULL 500 NULL NULL NULL
2/1/2012 NULL NULL 800 NULL NULL 800 NULL NULL
2/10/2012 NULL 700 NULL NULL NULL NULL 700 NULL
3/1/2012 1100 NULL NULL NULL NULL NULL NULL 1100

Answer 1

You can try the below query.
CREATE TABLE TEMP (
DATE DATETIME
,category VARCHAR(3)
,amount MONEY
,NAMES VARCHAR(5)
)
INSERT INTO TEMP
VALUES (
'1/1/2012'
,'ABC'
,1000.00
,'john'
)
INSERT INTO TEMP
VALUES (
'2/1/2012'
,'DEF'
,500.00
,'amy'
)
INSERT INTO TEMP
VALUES (
'2/1/2012'
,'GHI'
,800.00
,'blue'
)
INSERT INTO TEMP
VALUES (
'2/10/2012'
,'DEF'
,700.00
,'ivy'
)
INSERT INTO TEMP
VALUES (
'3/1/2012'
,'ABC'
,1100.00
,'mark'
)
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.category)
FROM temp c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT date, ' + #cols + ' from
(
select date
, amount
, category
from temp
) x
pivot
(
max(amount)
for category in (' + #cols + ')
) p '
execute(#query)

Answer 2

You can't use pivot like that, you need to pivot the data separately.
A quick way to get what you want would be:
WITH Table1 AS
(
SELECT date, [ABC],[DEF],[GHI]
from
(
select date
, amount
, category
, names
from temp
) AS x
pivot
(
MAX(Amount)
for category in ([ABC],[DEF],[GHI])
) AS A
)
,Table2 AS
(
SELECT date, [amy],[blue],[ivy],[john],[mark]
from
(
select date
, amount
, category
, names
from temp
) AS x
pivot
(
max(amount)
for names in ([amy],[blue],[ivy],[john],[mark])
) AS B
)
SELECT *
FROM Table1 A
INNER JOIN Table2 B on A.date = B.date;

Hope you got your result from this query.
CREATE TABLE #TEMP (DATE DATETIME,category VARCHAR(3),amount MONEY,NAMES VARCHAR(5))
INSERT INTO #TEMP VALUES ('3/1/2012','ABC',1100.00,'mark')
INSERT INTO #TEMP VALUES ('1/1/2012','ABC',1000.00,'john')
INSERT INTO #TEMP VALUES ('2/10/2012','DEF',700.00,'ivy')
INSERT INTO #TEMP VALUES ('2/1/2012','DEF',500.00,'amy')
INSERT INTO #TEMP VALUES ('2/1/2012','GHI',800.00,'blue')
select * into #Category from (-----CREATE PIVOT BASED ON CATEGORY FROM #TEMP TABLE AND INSERT DATA INTO #CATEGORY TABLE
select * from #TEMP
) as t1
pivot (sum(amount) for Category IN ([ABC],[DEF],[GHI])) AS CategoryAmount
select * into #Names from (-----CREATE PIVOT BASED ON NAMES FROM #TEMP TABLE AND INSERT DATA INTO #Names TABLE
select * from #TEMP
) as t1
pivot (sum(amount) for names IN ([amy],[blue],[ivy],[john],[mark])) AS CategoryAmount
--HERE IS YOUR FINAL QUERY WHERE YOU GOT YOUR RESULT AS PER YOUR REQUIREMENT
select c.DATE,SUM(c.ABC) ABC,SUM(c.DEF) DEF,SUM(c.GHI) GHI,SUM(n.John) JOHN,SUM(n.Amy) AMY,SUM(n.Blue) BLUE,SUM(n.Ivy) IVY,SUM(n.Mark) MARK from #Category C
inner join #Names n on c.DATE = n.DATE
GROUP BY C.DATE
drop table #TEMP,#Category,#Names
