Is it just me, or is the article missing?

Hi,

I urgently need to know how to carry out an UPSERT in SSIS 2005. If anyone knows the way to do it, please let me know as soon as possible.

TIA,

Uday.

Oh, upsert...thought this was the upskirt discussion.

But seriously, what's wrong with the following?

Update e

set ColumnName = i.ColumnName

from ImportTable i

JOIN TableName e on i.uniqueID = e.uniqueID

Insert TableName (ColumnName)

select i.ColumnName

from ImportTable i

LEFT JOIN TableName e on i.uniqueID = e.uniqueID

where e.uniqueID is null

Database 101, but is there some newfangled way to do this in the new Analytics? You'd still need to build the dimension and fact tables using SQL (or something), right?

Delete from the target table where the same data exists in the source table. At this point if the source row = target row its ok. If source row has updated values you dont care either becuase the next step is to insert all source rows to the target which is essentially overwritting rows that have been updated within the source.

The easiest way of all however would be to use some kind of auditing within you loads from source to target. But we dont live in a perfect world.

If I could VPN to a client site I would add a sample package but again, we dont live in a perfect world!!!!!

My question was not how do it in the DB directly. Im trying to figure out if there is a way in Sql Server Integration Services (DTS) to do the same using a transformation.

Hi, use Lookup transformation on SSIS data flow page with the referential table. It is possible to update in standard output flow or insert in configured error flow.

SSIS is memory hungry so is you use the LookUp trans will you will need to be mindful of how SSIS will chew all your memory. I've used the process I outlined above on up to 10 million rows (which is not a lot) but SSIS manages this very well and very fast.

Simply build your package using Execute SQL taks between dataflows to faciliate my process.

Oh cool! I should have thought of that before... thanks a lot :o)

I'm not handling such large data. But will be mindful of that... thanks for the warning.

Steve,

I think one of your indexes is slightly sick. We already know all about the sale. Now, we need the Upsert article, please.

(We all hope this is NOT a sign of things to come)

Regards,

Peter

OK, OK, apologies. That was the weirdest thing. The process we use to load the articles is generating an old one on disk for some reason. Did it again this morning and I didn't catch it last night.

It's up there now.
