Hi,
I have a column in table with xml type. I want to extract it row wise but it is giving me only first result

My Table has following data
id ItemId
1 <itemids><itemid>259</itemid><itemid>489</itemid></itemids>
2 <itemids><itemid>6834262</itemid><itemid>489</itemid></itemids>
3 <itemids><itemid>6603537</itemid></itemids>

select
tabId,
itemid.value('(/itemids//itemid/node())[1]','int') AS ItemIDA
from mytable;

query is only returning first ItemId against every Id.

Based on your sample data: -
IF object_id('tempdb..#yourTable') IS NOT NULL
BEGIN
DROP TABLE #yourTable;
END;

SELECT id, CAST(ItemId AS XML) AS ItemId
INTO #yourTable
FROM (VALUES(1, '<itemids><itemid>259</itemid><itemid>489</itemid></itemids>'),
(2, '<itemids><itemid>6834262</itemid><itemid>489</itemid></itemids>'),
(3, '<itemids><itemid>6603537</itemid></itemids>')
)a(id, ItemId);



You'd do it like this: -
SELECT id, ParamValues.ItemId.value('.','INT') AS ItemId
FROM #yourTable
OUTER APPLY ItemId.nodes('/itemids/itemid') ParamValues(ItemId);

If you litter your database queries with nolock query hints, are you aware of the side effects?
Try reading a few of these links...

(*) Missing rows with nolock
(*) Allocation order scans with nolock
(*) Consistency issues with nolock
(*) Transient Corruption Errors in SQL Server error log caused by nolock
(*) Dirty reads, read errors, reading rows twice and missing rows with nolock
