$sth->execute;

slice

max_rows

The second param to "fetchall_arrayref". Controls the size of each buffer.

Defaults to 500.

METHODS

See Data::Stream::Bulk::DoneFlag.

Calls "fetchall_arrayref" to get the next chunk of rows.

all

Calls "fetchall_arrayref" to get the raminder of the data (without specifying "max_rows").
