I wouldn't necessarily consider the 'bracket notation' a query, and it's very un-SQL like. It's simply three vector operations which returns a boolean vector e.g. (TRUE, FALSE, TRUE, ...), which is then used to select particular indices. I think this way of operating is more familiar to statisticians.
- Myrmornis 13y agoYes it's completely unlike SQL. Rather than declaring what is wanted and being agnostic about implementation, it actually specifies the implementation of the query, and does so using data structures of length equal to the dimension of the full table, so it's completely unscalable.
