Ever tried filtering on COUNT() with WHERE and hit a confusing error?

The problem: WHERE runs before GROUP BY, so aggregate functions don't exist yet. That's where HAVING comes in. It filters after grouping.

WHERE = filter individual rows
HAVING = filter aggregates

HAVING: Filtering Grouped Results

WHERE filters rows before grouping; HAVING filters after. Need "only cities with more than 10 customers"? That's HAVING.

ICYMI, here’s my review of #DuckDB performance improvement from v1.0 to v1.5 (just released). https://oxbowresearch.com/p/how-much-faster-is-duckdb-15-vs-10
How Much Faster is DuckDB 1.5 vs 1.0? A lot

I benchmarked every DuckDB minor release from 1.0.0 through the 1.5.0 dev build on TPC-H, TPC-DS, ClickBench, and SSB. The results tell a clear story of DuckDB quickly improving.

Yes. No more `ST_FlipCoordinates` fun with #DuckDB 1.5.0.

Today I'll be upgrading a couple of things to #DuckDB 1.5 and yet again, the folks at @duckdb provide a perfect way to adapt to a breaking change, here getting the order of x/y right:

- in 1.5 you can set geometry_always_xy = true to have xy in lat/long order, otherwise you get a warning
- in 2.0 not setting it, you get an error, but you can ofc use false to get <= 1.5 default behaviour
- in 2.1 make the new one the default

They did the same in 1.3 for lambda style.

Big Data on the Cheapest MacBook

How does the latest entry-level MacBook perform on database workloads? We benchmarked it using ClickBench and TPC-DS SF300. We found that it could complete both workloads, sometimes with surprisingly good results.
