Struct ReadCsv

Source

pub struct ReadCsv;

Expand description

READ_CSV(path [, delimiter]) - Read a delimited text file and emit one row per record.

Columns are inferred from the header row. Pass - as the path to read CSV from stdin (shares the same cached-once buffer with READ_STDIN / READ_JSONL).

Delimiter resolution:

Explicit 2nd arg wins (single ASCII char or \t escape).
Otherwise, .tsv → tab, .psv → pipe, everything else → comma.
Stdin (-) with no explicit delimiter defaults to comma.

Type inference, string interning, and other optimisations are inherited from the main CSV loader so behaviour matches sql-cli file.csv -q ....
