<para>
Retrieves the contents of one cell from a MySQL result set.
</para>
<para>
When working on large result sets, you should consider using one
of the functions that fetch an entire row (specified below). As
these functions return the contents of multiple cells in one
function call, they're MUCH quicker than
<function>mysql_result</function>. Also, note that specifying a
numeric offset for the field argument is much quicker than
specifying a fieldname or tablename.fieldname argument.

<para>
It can be the field's offset, the field's name, or the field's table
dot field name (tablename.fieldname). If the column name has been
aliased ('select foo as bar from...'), use the alias instead of the
column name. If undefined, the first field is retrieved.
