NAME
Data::Stream::Bulk::DBI - N-at-a-time iteration of DBI statement results.SYNOPSIS
use Data::Stream::Bulk::DBI; my $sth = $dbh->prepare("SELECT hate FROM sql"); # very big resultset $sth->execute; return Data::Stream::Bulk::DBI->new( sth => $sth, max_rows => $n, # how many at a time slice => [ ... ], # if you want to pass the first param to fetchall_arrayref );
DESCRIPTION
This implementation of Data::Stream::Bulk api works with DBI statement handles, using ``fetchall_arrayref'' in DBI.It fetches "max_rows" at a time (defaults to 500).
ATTRIBUTES
- sth
- The statement handle to call "fetchall_arrayref" on.
- slice
- Passed verbatim as the first param to "fetchall_arrayref". Should usually be "undef", provided for completetness.
- max_rows
- The second param to "fetchall_arrayref". Controls the size of each buffer.
Defaults to 500.
METHODS
- get_more
- 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").
