PARAMETERS
	      o $result
		- The query result identifier

	      o $index
		-$index   is   the   field   whose   type   will  be  retrieved.   The	possible  values  of  $index  depend  upon  the  value	of

		ingres_num_fields(3). If ingres.array_index_start is 0 then $index must be between 0 and ingres_num_fields(3)
		 - 1.

RETURN VALUES
       ingres_field_type(3)  returns  the  type  of a field in a query result or FALSE on failure. 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(3)). 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.
