NAME

MongoDB::BulkWriteView - Bulk write operations against a query document

VERSION

version v2.2.2

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_many( { '$inc' => { x => 2 } } );

# Update all documents matching the selector, with respect to a collation
bulk->find( { a => { '$gte' => 'F' } )->collation($collation)
      ->update_many( { '$inc' => { x => 2 } } );

# Update all documents
bulk->find( {} )->update_many( { '$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_many( { '$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 } )->delete_one();

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

# Update any arrays with the matching filter
bulk->find( {} )->arrayFilters([ { 'i.b' => 1 } ])->update_many( { '$set' => { 'y.$[i].b' => 2 } } );

# Remove all documents matching the selector, with respect to a collation
bulk->find( { a => { '$gte' => 'F' } )->collation($collation)->delete_many();

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

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.

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

METHODS

arrayFilters

$bulk->arrayFilters( $array_filters )->update_many( $modification );

Returns a new MongoDB::BulkWriteView object, where the specified arrayFilter will be used to determine which array elements to modify for an update operation on an array field.

collation

$bulk->collation( $collation )->delete_one;

Returns a new MongoDB::BulkWriteView object, where the specified collation will be used to determine which documents match the query document. A collation can be specified for any deletion, replacement, or update.

delete_many

$bulk->delete_many;

Removes all documents matching the query document.

delete_one

$bulk->delete_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_many

$bulk->update_many( $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.
