回答1:

Assuming Target_Database is the database where the table is that you want to update and Source_Database is the database where the table is you are using to update from.

Your query should look something like this.....

USE [Target_Database]
GO

UPDATE t
 SET t.iexp  = S.iexp 
FROM K_monster t 
INNER JOIN [Source_Database].[Schema].[K_monster] S 
ON t.ID = S.ID
GO
