the value

is 1 (the default)
then index must be
between 1 and the value returned
by ingres_num_fields(). If ingres.array_index_start
is 0 then index must
be between 0
and ingres_num_fields() -
1.
ingres_field_type() returns the type of a

types returned are IIAPI_BYTE_TYPE,
IIAPI_CHA_TYPE, IIAPI_DTE_TYPE,
IIAPI_FLT_TYPE, IIAPI_INT_TYPE,
IIAPI_VCH_TYPE. Some of these types can map to more
than one SQL type depending on the length of the field (see
