# Method Mysql.mysql_result()->fetch_field()

Method fetch_field

  `int|mapping(string:mixed) fetch_field()`

Description

  Return specification of the current field.

  Returns a mapping with information about the current field, and advances the field cursor one step. Returns `0` (zero) if there are no more fields.

  The mapping contains the same entries as those returned by Mysql.mysql->list_fields() , except that the entry `"default"` is missing.

Note

  This function is usually not enabled. To enable it `SUPPORT_FIELD_SEEK` must be defined when compiling the mysql-module.
