T-SQL Trigger Update

Question

I have a table with 3 fields [ID, Name, LastUpdated].
LastUpdated has a default value of \"GetDate() so it automatically fills itself when a new record is added.

Answer 1

CREATE TRIGGER dbo.refreshModifyDate 
      ON  tStoreCategoriesImages
      FOR INSERT, UPDATE
AS 
  BEGIN
    SET NOCOUNT ON;
        update t set t.ModifyDate = getdate() from tStoreCategoriesImages t 
        inner join inserted i on i.ID = t.ID
  END
GO

Answer 2

Update table1
set LastUpdated = getdate()
from inserted i, table1 a
where i.pk1 = a.pk1

Answer 3

From 'INSERTED', table INSERTED is common to both the INSERT, UPDATE trigger.

CREATE TRIGGER dbo.Table1_Updated
ON dbo.Table1
FOR INSERT, UPDATE /* Fire this trigger when a row is INSERTed or UPDATEd */
AS BEGIN
  UPDATE dbo.Table1 SET dbo.Table1.LastUpdated = GETDATE()
  FROM INSERTED
  WHERE inserted.id=Table1.id
END
