There will be no singularity

> can you write a new Radiohead song about data lineage? Verse 1: I’m tracing the data lineage From its source to where it ends Every table and column Every join and every blend Chorus: I’m on the path of data lineage Following the trail of bits and bytes Through the labyrinth of technology Where the truth of data lies Verse 2: I’m chasing the data lineage From the past to the present tense Every calculation and transformation Every rule and every exception Chorus: I’m on the path of data lineage Following the trail of bits and bytes Through the labyrinth of technology Where the truth of data lies Bridge: I see the patterns and the connections I see the errors and the corrections I see the beauty and the complexity Of the data lineage Outro: I’m on the path of data lineage Following the trail of bits and bytes Through the labyrinth of technology Where the truth of data lies.

Только сейчас заметила, что у ребят из IT Resume можно прямо на сайте пробовать решать sql задачки. Вот задача про когорты, например: https://itresume.ru/problems/sql-cohort Где еще практиковать SQL бесплатно: - sql-ex - sqlbolt - sql-academy - stepik тренажер - w3schools - sqlzoo - pgexercises

Now in snowflake...

create table t (a int, b int, c int);
create view v as 
    select * exclude (a) rename (b as d, c as e) from t
;

... and in dwh.dev and parsers.dev!

duckdb going mad... UNION Type

CREATE TABLE messages(u UNION(num INT, error VARCHAR));
INSERT INTO messages VALUES (42);
INSERT INTO messages VALUES ('oh my globs');

FROM-first

-- SELECT clause is optional, SELECT * is implied (if not included)
FROM tbl;

-- first 5 rows of the table
FROM tbl LIMIT 5;

-- SELECT can be used after the FROM
FROM tbl SELECT l_orderkey;

-- insert all data from tbl1 into tbl2
INSERT INTO tbl2 FROM tbl1;

BTW SQL standard already has special syntax for it:

TABLE tbl;

COLUMNS Expression

SELECT MIN(COLUMNS(*)), COUNT(*) from obs;
SELECT COLUMNS('val[0-9]+') from obs;

List comprehension support

SELECT [x + 1 for x in [1, 2, 3]] AS l;
