VERSION¶

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.
