Hello,
I'm trying to do some "update if exists otherwise insert" logic in my SSIS package but am running into problems. I researched and found that one way to do it is with Lookup transform, with redirection of error output. But this causes problems as I run out of memory (I assume) because random components start failing for no reason. My reference table has over 2 million rows also.
Any ideas on best method of doing upserts?
