Ms sql updating multiple rows

Therefore, the first two statements in the trigger should look like it is shown below. Data2(Col int not null) go create trigger trg_Data_AI on dbo.

Data2 after insert as select 'After Insert' as [Trigger] ,@@Row Count as [Row Count] ,(select count(*) from inserted) as [Inserted Cnt] ,(select count(*) from deleted) as [Deleted Cnt] go create trigger trg_Data_AU on dbo.

Performance Tip: The conditional behavior described for the MERGE statement works best when the two tables have a complex mixture of matching characteristics.

Data2 after update as select 'After Update' as [Trigger] ,@@Row Count as [Row Count] ,(select count(*) from inserted) as [Inserted Cnt] ,(select count(*) from deleted) as [Deleted Cnt] go create trigger trg_Data_AD on dbo.

Data2 after delete as select 'After Delete' as [Trigger] ,@@Row Count as [Row Count] ,(select count(*) from inserted) as [Inserted Cnt] ,(select count(*) from deleted) as [Deleted Cnt] gomerge into dbo.

For example, inserting a row if it does not exist, or updating the row if it does match.

When simply updating one table based on the rows of another table, improved performance and scalability can be achieved with basic INSERT, UPDATE, and DELETE statements.
