The optional <parameter>result_type</parameter> parameter accepts a
constant and determines how the returned array will be indexed. Using
<constant>SQLITE_ASSOC</constant> will return only associative indices
(named fields) while <constant>SQLITE_NUM</constant> will return only
numerical indices (ordinal field numbers).
<constant>SQLITE_BOTH</constant> will return both associative and
numerical indices. <constant>SQLITE_ASSOC</constant> is the default for
this function.
