I know there have been a plethora of Q's asked around this but after reading, nobody seems to have the same trouble as I do.
Background Info: I am looking to doing incremental updates into a Cube, but have no timestamp of update on the table. I now am looking at creating a standalone table which updates via a trigger with the gkey and current datetime stamp, when a record is updated.
My trigger on the table is as follows:
CREATE TRIGGER trgAfterUpdateVisitDetails ON [visit_details]
FOR UPDATE
AS
begin
declare @VD_Gkey nvarchar
declare @today DATETIME = SYSDATETIME()
insert into [UpdatedVD]
SELECT
@VD_Gkey, @today
FROM
[visit_details]
End
This gives me an output like below but with 917 lines of the same:
+---------+-------------------------+
| VD_Gkey | today |
+---------+-------------------------+
| NULL | 2014-01-02 11:21:23.963 |
| NULL | 2014-01-02 11:21:23.963 |
+---------+-------------------------+
I know it's going to be something pretty simple but I cannot get my head around this.
Any help would be brilliant.
Thanks.
You just need to access the inserted
and deleted
pseudo-tables:
CREATE TRIGGER trgAfterUpdateVisitDetails ON [visit_details]
FOR UPDATE
AS
begin
insert into
[UpdatedVD]
SELECT
i.VD_Gkey, CURRENT_TIMESTAMP
FROM
inserted i;
End
