Hi

How to use Single update Query for both tables

CREATE TABLE MAS1
(
Id int primary key identity(1,1),
MasName varchar(50),
Tempid int,
RefTempId int
)

CREATE TABLE MAS2
(
Id int primary key identity(1,1),
Tempid int,
RefTempid int
)


Insert into MAS1 values('John',1,2)
Insert into MAS1 values('John',3,5)
Insert into MAS1 values('John',8,11)

Insert into MAS2 values(1001,2001)
Insert into MAS2 values(3001,5001)
Insert into MAS2 values(8001,1001)


select * from MAS1
select * from MAS2

--I need single update Query but Both table column

--ex:set MAS1.Tempid=MAS2.Tempid,Mas1.RefTempid=Mas2.RefTempid
-- where mas1.id=mas2.id and mas1.id=1

0	@Jayakumars Sir, logically speaking, it does not make sense. Because, you are trying to update the same field of Mas2 table by which you have updated the Mas1. So the value will remain same. That's the cause of the error. Incase, however, you need to again update Mas2 by Mas1, then perform another Update like UPDATE mas2 SET mas2.RefTempid=mas1.RefTempid FROM MAS2 mas2 JOIN MAS1 mas1 ON mas2.id=mas1.id /* Id Tempid RefTempid 1 1001 2001 2 3001 5 3 8001 11 / -- Thanks & Regards, RNA Team Jayakumars, if this helps please login to Mark As Answer*. \| Alert Moderator

UPDATE mas2 

SET 

mas2.RefTempid=mas1.RefTempid

FROM MAS2 mas2

JOIN MAS1 mas1 ON mas2.id=mas1.id

Id	Tempid	RefTempid

1	1001	2001

2	3001	5

3	8001	11
