I definitely saw EXPLAIN in a similar question before, so I’m leaning towards that being one of the correct answers.

I feel like nz_plan might be related to showing plans, but I don't remember using it in practice.

I remember practicing with EXPLAIN PLAN, but I can't recall if it was the right syntax for this question.

I think the command to show a query plan without executing it is EXPLAIN, but I'm not sure if it's just that one or if there's another option.

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, the age-old dilemma of planning versus execution. I'm going with C and D, the EXPLAIN commands, to get the plan without the performance hit.

I prefer using nzsql -t querytext -0 planfile.pln to get the query plan without running it.

Haha, I'm going to go with C and D just to be safe. Who needs to actually run the query when you can just look at the plan, am I right?
