 list_errnos( detail => 1, query => "'No such'");

Search specific errnos.

Arguments ('*' denotes required arguments):

    Return array of full records instead of just ID fields.

    By default, only the key (ID) field is returned per result entry.

  • fields => array[str]

    Select fields to return.

  • number => int

    Only return records where the 'number' field equals specified value.

  • number.in => array[int]

    Only return records where the 'number' field is in the specified values.

  • number.is => int

    Only return records where the 'number' field equals specified value.

  • number.isnt => int

    Only return records where the 'number' field does not equal specified value.

  • number.max => int

    Only return records where the 'number' field is less than or equal to specified value.

  • number.min => int

    Only return records where the 'number' field is greater than or equal to specified value.

  • number.not_in => array[int]

    Only return records where the 'number' field is not in the specified values.

  • number.xmax => int

    Only return records where the 'number' field is less than specified value.

  • number.xmin => int

    Only return records where the 'number' field is greater than specified value.

  • query => str

    Search.

  • sort => str

    Order records according to certain field(s).

    A list of field names separated by comma. Each field can be prefixed with '-' to specify descending order instead of the default ascending.

    Only return records where the 'string' field contains specified text.

  • string.in => array[str]

    Only return records where the 'string' field is in the specified values.

  • with_field_names => bool

    Return field names in each record (as hash/associative array).

    When enabled, function will return each record as hash/associative array (field name => value pairs). Otherwise, function will return each record as list/array (field value, field value, ...).

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
