Just one question. I added few rows in your table. Does it match with your actual data? I mean can this table have multiple records like I showed above?
December 9, 2011 at 6:32 am
We need more details about your data model.
How are the rows connect to each other?
December 9, 2011 at 6:32 am
I don't like that there is no ID to show where 1 record ends and another begins, but try this
BEGIN TRAN
SELECT Id, FieldName, FieldValue
INTO #temp
FROM (SELECT 1, 'Name', 'John Lucas'
UNION ALL SELECT 2, 'DOB', '12/11/1990'
UNION ALL SELECT 3, 'Amount', '5000') a(Id, FieldName, FieldValue)
SELECT Name, DOB, Amount
FROM (SELECT FieldName, FieldValue
FROM #temp) DataTable
PIVOT (MAX(FieldValue) FOR FieldName IN (Name,DOB,Amount) ) AS p
ROLLBACK

This is vertically data storage
I can not put the hard code fieldname bcz user can add more field name in it.

You answered my question indirectly. Is there any good reason for doing it?
December 9, 2011 at 6:40 am
Yes
Bcz we don't want to restrict user to entere fixed column data.
The application requirement is user can add custom column and its value while processing documents.
December 9, 2011 at 6:44 am
But you should use a unique key for each user input like:
UID ID Fieldname Fieldvalue
1 1 Name John
1 2 DOB 12/11/1990
1 3 Amount 5000
So you could select and group the rows by UID
December 9, 2011 at 6:46 am
can you provide me the query?

No you don't.
Read what I wrote again, it uses dynamic SQL to get all of the fieldName's from the table then builds your query string from that. Once the string is built, it executes the string, so no matter how many new fieldName's are added to the table it will always work.
DECLARE @SQL AS VARCHAR(MAX)
SELECT @SQL = COALESCE(@SQL, '') + 'MAX(CASE WHEN FieldName = ''' + FieldName + ''' THEN FieldValue ELSE NULL END) AS ''' + FieldName + ''','
FROM #temp
GROUP BY FieldName
SET @SQL = 'SELECT ' + SUBSTRING(@SQL,1,LEN(@SQL)-1) + ' FROM #temp GROUP BY RecordID'
EXEC(@SQL)
