Re: NL & Hash Outer Join question

Hmmm .... we don't use system stats, simply because we don't. As for 10053 trace, this specific query occures in middle of a process. This process assigns chunks of data to upto 10 slaves, grabs data returned by them, analyzes that and spits out final output.

So, I could only trace the whole process for 10053 trace. Now, I must admit that my latin is far better than the cryptic language of 10053 trace. So, it is my plan to print it out, and scan through it over the weekend.

thanks for the input.
