The query result identifier
index
index is the field whose type will be
retrieved.
The possible values of index depend upon
the value
of ingres.array_index_start.
If ingres.array_index_start
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
field in a query result или FALSE в случае возникновения ошибки. Examples of
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
ingres_field_length()). For example
IIAPI_FLT_TYPE can be a float4 or a float8. For detailed
information, see the Ingres OpenAPI User Guide, Appendix
"Data Types" in the Ingres documentation.
