I've used EXPLAIN before to see the query plan, so I'm confident that's one of the right answers. The other one is a bit trickier, but I think E might be it - the nzsql command with the -0 option sounds like it could output the plan to a file.
Okay, let me walk through this step-by-step. A and B don't look right, as I don't recognize those commands. C mentions PLANGRAPH, which I'm not familiar with. That leaves D and E as the most likely options. I'll go with those two.
Hmm, I'm a bit confused on this one. I know EXPLAIN is used to show the query plan, but I'm not sure about the other options. I'll have to think this through carefully.
I'm pretty sure the answer is D and E. EXPLAIN will show the query plan without running the query, and nzsql with the -0 option will output the plan to a file.
Ah, this is a tricky one! I'm going to go with C and D. EXPLAIN PLANGRAPH and EXPLAIN seem like the most logical choices to view the plan without running the query.
I'm pretty sure the correct answers are C and D. EXPLAIN PLANGRAPH and EXPLAIN are the commands that will display the query plan without executing the query.
I believe it's actually D) EXPLAIN and E) nzsql -t querytext -0 planfile.pln. Those are the commands to display the query plan without executing the query.
