Updating a view in sql server
I will also show you one way of handling this situation. I also created a Linked Server named SERV1 on SERV2 that connects to SERV1.Now we will execute some queries on SERV2 using the linked server.Since you are using Express Edition and can't actually use partitioning, I have a different approach to recommend: dynamic UPDATEs that only affect the table(s) represented in @Start Date / @End Date.You'll have to populate the list of parameters twice; once with their data types - this should be easy as I presume these are declared somewhere already.Please use the following SQL Query to check the inserted records in the Employee table-- SQL Server INSTEAD OF UPDATE Triggers Example USE [SQL Tutorial] GO SELECT [Name] ,[Education] ,[Occupation] ,[Yearly Income] ,[Sales] ,[Server Name] ,[Server Instance Name] ,[Insert Time] FROM [Employee Table Audit]OUTPUTHere, you can see that the trigger has interested 4 new records into Employee audit table In this example, we will show you, How to Update all the records in the audit table (triggered table) using the Instead of Update Triggers in SQL Server. For this, we are using the INNER JOIN.-- Example for INSTEAD OF UPDATE Triggers in SQL Server USE [SQL Tutorial] GO CREATE TRIGGER Instead Of UPDATETrigger Example on [Employee Table] INSTEAD OF UPDATE AS UPDATE [Employee Table] SET [Employee Table].[Name] = 'Tutorial Gateway', [Employee Table].[Education] = ins. Occupation, [Employee Table].[Yearly Income] = ins. Yearly Income, [Employee Table].[Sales] = 55555 FROM [Employee Table] INNER JOIN INSERTED AS ins ON [Employee Table]. ID PRINT 'We Successfully Fired Our Third INSTEAD OF UPDATE Triggers in SQL Server.' GOIt means, whatever you pass the values to the name, and Sales columns, Instead of Update Trigger in Sql Server will insert the ‘Tutorial gateway’, and 55,555.For this, we are using the MERGE Statement.-- Example for INSTEAD OF UPDATE Triggers in SQL Server USE [SQL Tutorial] GO CREATE TRIGGER Instead Of UPDATETrigger Example on [Employee Table] INSTEAD OF UPDATE AS DECLARE @Action Peformed VARCHAR(50) IF UPDATE(Yearly Income) BEGIN SET @Action Peformed = 'Updated Yearly Income' END ELSE BEGIN SET @Action Peformed = 'Updated Sales' END MERGE [Employee Table Audit] AS Audit Tab USING (SELECT * FROM INSERTED) AS Emp ON Audit Tab. ID WHEN MATCHED THEN UPDATE SET Audit Tab.[Name] = Emp.
From the below code snippet you can see that, we are using the INSERT INTO SELECT Statement to select all the records that are inserting into Employee table, and then We are inserting those records into the Audit table.In general, we use these triggers on Views In this example, we will show you, How to create an Instead of update Triggers in SQL Server.For instance, if you want to restrict the users from updating the records in the original table, and you want those updated logs in another historical table then you can use this trigger.SQL Server Linked Servers are a great to query remote databases, but when running update queries they don't always behave like they should.In this tip I will show you a situation where several queries worked fine, but a few did not behave as planned. I created this table with 90K rows of test data in database db1 on SERV1.
