alternative for slowly changing dimension (SCD) object

Hi,

I think slowly changing dimension object is not a good choice to update my dimension. It's running slower than I expected. my dimension records has surrogate keys from a control table that SCD is looking up whenever it encounters a new record.

Any alternative I can use?

Hi Jamie,

I tried to use your example with the lookup to check if record is existing or not. If the record is already existing and has changed, then that means that I have to use the oledb command to update my table? based on the forums i read, this object runs slow. do i have any alternative for this?

Cherriesh,

As part of the thread that Jamie posted earlier, there is a discussion on alternatives -- namely loading your updates to a staging table that you later use an Execute SQL task to perform the batch update. Please read through that entire thread.
