Documentation​

Returns a materialized column containing rows of this column. For in-memory columns this just returns the column as-is, or truncated depending on max_rows.

Arguments​

  • max_rows: specifies the maximum number of rows to read. By default, it will return all rows for in-memory columns, but in Database it will read up to 1000 rows and warn if there are more.
