ingres_field_type() 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()). For example "IIAPI_FLT_TYPE" can be a float4 or a float8. For detailed information, see the Ingres/OpenAPI User Guide - Appendix C.

index is the number of the field and must be between 1 and the value given by ingres_num_fields().

See also ingres_query(), ingres_fetch_array(), ingres_fetch_object(), and ingres_fetch_row().
