Hi,
Run below query to find updated user:
SELECT
T2.[CardCode], T2.[CardName], T2.[GroupNum] as Newvalue,
T1.[GroupNum] as Oldvalue , T3.[U_NAME] as UpdatedUser , T4.[U_NAME]
as CreatedUser FROM ACRD T0 left join ACRD T1 on t0.[CardCode] =
T1.[CardCode] and t0.loginstanc = t1.loginstanc-1 left JOIN OCRD T2
ON T0.cardcode = T2.CardCode left join OUSR T3 on t3.userid =
t0.usersign2 left JOIN OUSR T4 ON T4.USERID = T1.userSign left
JOIN OCTG T5 ON T0.GroupNum = T5.GroupNum WHERE T2.[GroupNum] <>
T1.[GroupNum] and datediff(dd, T1.[updateDate] ,getdate())<=0
GROUP BY T2.[CardCode], T2.[CardName], T2.[GroupNum], T1.[GroupNum] ,
T3.[U_NAME] , T4.[U_NAME]
Hope helpful.
Thanks & Regards,
