What Could Go Wrong?

It's the law of unintended consequences: things happening that you don't expect from a seemingly unrelated area. This article talks about a data center having leaks from carpet cleaning above. The concrete floor had aged and the carpet cleaners dumped water on the carpet to soak it through and it leaked. I'm not sure how people have data centers below office floors, but I know I've had a number of them at different companies where I've worked.

Question of the Day

STRING_AGG's behavior

Executing the following script (Sql Server 2022), you get the table t0 with 10 rows:
CREATE TABLE t0
( id     INT PRIMARY KEY
, field1 VARCHAR(1000)
, field2 VARCHAR(MAX));
INSERT INTO t0
SELECT
  gs.value
, REPLICATE ('X', 1000)
, REPLICATE ('Y', 1000)
FROM generate_series(1, 10, 1) gs;
GO
What happens if you execute the following statements?
  1. select STRING_AGG(field1, ';') within group (order by id)  from t0;
  2. select STRING_AGG(field2, ';') within group (order by id)  from t0;
