I have written an update statement which is updating some fields like this--
update L
set L.UpdateBy = E.UserID,
L.CreatedByID = E.UserID
from EmployeeProfile E
inner join LocationMaster L on E.EmployeeID=L.UpdateBy
As it will only updating in LocationMaster table.
I want to update all the tables that has columns(UpdateBy,CreatedByID).
Is it possible?

you could build the queries you want to execute for all tables meeting your criteria.

if the table has a value in the UpdateBy column, are you trying to set the CreatedByID tot eh same value?

what is the purpose of joining to the Employee table if the data is already in the target table anyway? if the data is blank in LocationMaster, your update will leave those rows null still.

Anyway, as far as building the query goes,

my example below below builds the same SQL statement you demoed for every table that has both a UpdateBy column and a CreatedByID column.

is that what you want?

it's a little wierd to want to blindly update like that...since the data is already there!

SELECT

'

update L

set L.UpdateBy = E.UserID,

L.CreatedByID = E.UserID

from EmployeeProfile E

inner join ' + OBJECT_NAME(T1.object_id) + ' L on E.EmployeeID=L.UpdateBy

' AS cmd

FROM sys.columns T1

INNER JOIN sys.columns T2

ON T1.object_id = T2.object_id

WHERE T1.name = 'UpdateBy'

AND T2.name = 'CreatedByID'

edit

is this what you are really trying to do?

update LocationMaster

set UpdateBy = CreatedByID

WHERE CreatedByID IS NOT NULL

--AND UpdateBy IS NULL --?? only where it's currently blank/null?

the MERGE statement might help you there but I would create separate update statements and run as a single transaction. Also use nested if statements so that if one update fails everything gets rolled back.

make sense?
