Oracle 26ai¹ was released yesterday.

From the SQL standpoint it's worth mentioning that is has got the QUALIFY clause:

I bet this starts an avalanche (there are already PostgreSQL patches).

¹ 26ai is the marketing version, 23.26.0 is the technical version.

QUALIFY clause (window functions)

The best thing is how they “solved” the problem ;)

nixCraft @cyberciti.biz · Sep 13

they used AI to uppercase text? lol.

A Reddit post titled "Wow... we've been burning money for 6 months." The post's author, u/me_z, describes how their company's OpenAI usage was costing around $1200 a month. They are using GPT-4 for simple tasks like extracting phone numbers, checking for profanity, reformatting JSON, and uppercasing text. The author ends by asking, "Am I an idiot? How much are you guys spending?"

After being « gone fishin' » during summertime I just updated my website for the releases that happened during that time:

* MariaDB 11.8 and 12.0
* Oracle 23.9
* Db2 12.1.2

All charts on modern-sql.com and use-the-index-luke.com are updated.

My favorite change is that MariaDB got an improved implementation of the WHERE year(...) = ? rewriting. use-the-index-luke.com/blog/2024-12...

In picture: the green check mark used to be yellow, with the "a" footnote: Unconditionally rewritten — even if only a matching function-based index exists

Index your database with caution.

Every new index causes:

(a) Increased storage overhead (and in turn, data duplication)
(b) Increased write over head for INSERTs

The general principle here is that indexing improves read performance but hurts write performance.

Do you still manually write SQL queries or rely entirely on ORMs?

Test whether a value is valid #JSON or not with

WHERE val IS JSON

You can also use this to test if the value is a JSON

Object
Array

And check if there are duplicate key names

@winand.at‬ investigates

… IS JSON [ARRAY|OBJECT|SCALAR]

Check JSON syntax in SQL, test for Arrays, Objects or Scalars

SQLite can serve as a robust container format, offering transactions, indexing, and SQL querying. Compared to ZIP, it adds structure but also overhead. It's a powerful option for complex structured data files. #Databases 6/6

That “*” indeed causes lot of misconceptions in both areas: NULL treatment and performance.

Lætitia @l-avrot.bsky.social · May 10

Do you remember I tried to change Postgres code to remember the not meaningful necessity for the star in count(*)? Well, I’m just saying that other DBMS like @clickhouse.com did.

It is not even saying "for private reasons". IMHO, something went terribly wrong (and might continue to go wrong).

Change my mind.
