Hello, I'm a student of Korea Advanced Institute of Science and Technology in Korea.

 

I want to compare late materialization with join and invisible join on monetdb.

But when i typed SQL query, i couldn't choose which query plan to use.

There was no choice to me. I think query optimizer choose some join method.

Can I choose join method? or control query plan?

 

I installed Monetdb on my desk-top and followed tutorials. Everything is done. There is no error.

 

In this situation, i tried to control query plan.

So I read reference on official homepage.

But I couldn't find the information that how to control query plan.

 

Can I control query plan?

If I can, I really really want to know how do that.

Where can i find some example?

 

Please give me your favor.
