NAME

MongoDB::BulkWriteResult - MongoDB bulk write result document

VERSION

version v2.2.2

SYNOPSIS

    # returned directly
    my $result = $bulk->execute;

    # from a WriteError or WriteConcernError
    my $result = $error->result;

    if ( $result->acknowledged ) {
        ...
    }

DESCRIPTION

This class encapsulates the results from a bulk write operation. It may be returned directly from execute or it may be in the result attribute of a MongoDB::DatabaseError subclass like MongoDB::WriteError or MongoDB::WriteConcernError.

ATTRIBUTES

inserted_count

Number of documents inserted

upserted_count

Number of documents upserted

matched_count

Number of documents matched for an update or replace operation.

deleted_count

Number of documents removed

modified_count

Number of documents actually modified by an update operation. This is not necessarily the same as "matched_count" if the document was not actually modified as a result of the update.

This field is not available from legacy servers before version 2.6. If results are seen from a legacy server (or from a mongos proxying for a legacy server) this attribute will be undef.

You can call has_modified_count to find out if this attribute is defined or not.

upserted

An array reference containing information about upserted documents (if any). Each document will have the following fields:

• index — 0-based index indicating which operation failed

• _id — the object ID of the upserted document

upserted_ids

A hash reference built lazily from upserted mapping indexes to object IDs.

inserted

An array reference containing information about inserted documents (if any). Documents are just as in upserted.

inserted_ids

A hash reference built lazily from inserted mapping indexes to object IDs.

write_errors

An array reference containing write errors (if any). Each error document will have the following fields:

• index — 0-based index indicating which operation failed

• code — numeric error code

• errmsg — textual error string

• op — a representation of the actual operation sent to the server

write_concern_errors

An array reference containing write concern errors (if any). Each error document will have the following fields:

• index — 0-based index indicating which operation failed

• code — numeric error code

op_count

The number of operations sent to the database.

batch_count

The number of database commands issued to the server. This will be less than the op_count if multiple operations were grouped together.

METHODS

assert

Throws an error if write errors or write concern errors occurred.

assert_no_write_error

Throws a MongoDB::WriteError if count_write_errors is non-zero; otherwise returns 1.

assert_no_write_concern_error

Throws a MongoDB::WriteConcernError if count_write_concern_errors is non-zero; otherwise returns 1.

count_write_errors

Returns the number of write errors

count_write_concern_errors

Returns the number of write errors

last_code

Returns the last code field from either the list of write_errors or write_concern_errors or 0 if there are no errors.

last_errmsg

Returns the last errmsg field from either the list of write_errors or write_concern_errors or the empty string if there are no errors.

last_wtimeout

True if a write concern timed out or false otherwise.
