SQL Server Deadlock issue

Question

Hello,
I'm getting deadlock on update statement..Can someone help me how to resolve..?
Query 1,UPDATE tblICWMST SET SOFLG='W', LCKUSER='MDPA', LCKDATE='20140530 12:55:42 PM' WHERE RECUID=82837 (Recuid is the cluster index)
Query 2,UPDATE tblSOMAST SET SPECIAL='' WHERE RECUID=1571252  (Recuid is the cluster index)
Thanks for the reading.

Answer 1

There is insufficient information to answer the question. Presumably the processes both run a multi-statement transaction have performed an operation on the table which the other process now tries to update.
This query will return all deadlocks currently registered in the System Health session:
SELECT
xed.value('@timestamp', 'datetime2(3)') as CreationDate,
xed.query('.') AS XEvent
FROM
SELECT CAST([target_data] AS XML) AS TargetData
FROM sys.dm_xe_session_targets AS st
INNER JOIN sys.dm_xe_sessions AS s
ON s.address = st.event_session_address
WHERE s.name = N'system_health'
AND st.target_name = N'ring_buffer'
) AS Data
CROSS APPLY TargetData.nodes('RingBufferTarget/event[@name="xml_deadlock_report"]') AS XEventData (xed)
ORDER BY CreationDate DESC
