The copy-pastes and explanations blog for SQL code, errors and daily cases!
This blog is a 'list' of actions that always good to have available.
The copy-paste concept here is short and clear explanations and descriptions (no long stories!) and - of course - the code to take (copy) and use (paste).
The blog deals in the database (mostly) and software issues.

APPLY causes the right-side query to execute once per result in the left-side query.
CROSS only considers matching rows like INNER JOIN.
