man MongoDB::BulkWriteResult (3): MongoDB bulk write result document

VERSION

version v1.2.3

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
