VERSION

version v0.999.998.5

SYNOPSIS

my $bulk = $collection->initialize_ordered_bulk_op;

# Update one document matching the selector
bulk->find( { a => 1 } )->update_one( { '$inc' => { x => 1 } } );

# Update all documents matching the selector
bulk->find( { a => 2 } )->update( { '$inc' => { x => 2 } } );

# Update all documents
bulk->find( {} )->update( { '$inc' => { x => 2 } } );

# Replace entire document (update with whole doc replace)
bulk->find( { a => 3 } )->replace_one( { x => 3 } );

# Update one document matching the selector or upsert
bulk->find( { a => 1 } )->upsert()->update_one( { '$inc' => { x => 1 } } );

# Update all documents matching the selector or upsert
bulk->find( { a => 2 } )->upsert()->update( { '$inc' => { x => 2 } } );

# Replaces a single document matching the selector or upsert
bulk->find( { a => 3 } )->upsert()->replace_one( { x => 3 } );

# Remove a single document matching the selector
bulk->find( { a => 4 } )->remove_one();

# Remove all documents matching the selector
bulk->find( { a => 5 } )->remove();

# Remove all documents
bulk->find( {} )->remove();

DESCRIPTION

This class provides means to specify write operations constrained by a query document.

To instantiate a MongoDB::BulkWriteView, use the find method from MongoDB::BulkWrite or the "upsert" method described below.

Except for "upsert", all methods have an empty return on success; an exception will be thrown on error.

METHODS

remove

$bulk->remove;

Removes all documents matching the query document.

remove_one

$bulk->remove_one;

Removes a single document matching the query document.

replace_one

$bulk->replace_one( $doc );

Replaces the document matching the query document. The document to replace must not have any keys that begin with a dollar sign, $.

update

$bulk->update( $modification );

Updates all documents matching the query document. The modification document must have all its keys begin with a dollar sign, $.

update_one

$bulk->update_one( $modification );

Updates a single document matching the query document. The modification document must have all its keys begin with a dollar sign, $.

upsert

$bulk->upsert->replace_one( $doc );

Returns a new MongoDB::BulkWriteView object that will treat every update, update_one or replace_one operation as an upsert operation.
