По прогнозу погоды: дождь из языковых моделек, генерирующих код. Внезапно и неожиданно AWS зарелизил Code Whisperer. Это тоже самое, что и Copilot, только (вроде как) умеет в styleguide’ы проекта смотреть и больше берет из описания и контекста вокруг.

Выглядит неплохо, надо пощупать получше (Copilot смотрел еще в бете, не очень понравилось). Больше картинок с примерами есть в статье Techcrunch’a.

Результаты опроса аудитории StackOverflow по используемым СУБД. Удивляет популярность узкоприменимой SQLite.

Машка с муськой вместе дают огромный перевес. Постгри, конечно, уверенно тащит, хотя раньше никто не верил.

Time to update my open source SQL tools collection!

Yet another one SQL killer (modern language for transforming data — a simple, powerful, pipelined SQL replacement). Written in RUST :)

To distract from the problem, I randomly deleted 5 rows from the table.... :)))

SQL-WTF SQL-TIL

A few words about this.
At this moment, you must specify an alias for all sub-selects in FROM clause.
It's valid for PostgreSQL and MySQL.

In Snowflake you can skip it. But under the hood Snowflake name it automatically as "values". So, you can't use more than one unnamed sub-select in FROM clause, because "values" will conflict. And yes, you can address it as "values".*

Btw, there are some more "automatic aliases" in Snowflake:
- "VALUES" (capital letters, not the same) for values()
- "STAGE" for stages
- "LIST_DIR_TABLE" for directory tables

Absolutely insane behavior with sub-selects (named or unnamed) in the best and most popular DB in the world (he-he) - SQLite!

select * from (select 1) a, (select 1) b
