Ticket(s) Closed

• Closes Enhance EXPLAIN Statement: Add analyze option, Support style option #124

What

Why

How

Support the ANALYZE option: add a timer to record the actual execution time.
Support the STYLE option: Provide the query plan and execution time in DuckDB style.

Tests

It depends on sqlparser apache/datafusion-sqlparser-rs#1426. Awaiting the next release of the library.

Should this be based off of #140?

:) It actually doesn’t depend on #140; it’s just that part of them are the same. (split the explain in a single file.)

Got it. Let's still get the PREPARE PR in first though, since this one is blocked. Thank YOU for doing this, your PRs are always so clean!

[philippemnoel]

Could you please provide output examples for all the style/options you are adding here? I.e. what the query looks like, and what the output looks like? I'd like to build a better understanding of what this will look like before we merge anything.

Also some tests, but I understand this PR isn't ready for review yet.

Now supports ：

1. analyze (add a execution time statistics)
2. duckdb style
3. duckdb style and analyze

We can consider whether we need to add this style option.
The output of the EXPLAIN command in DuckDB differs significantly from that of PostgreSQL. Therefore, I would like to introduce a style option that allows users to obtain more detailed information about the query plan and performance tuning.

That looks really great. I think we should totally add this STYLE option :). Great idea!
