## 戻り値

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.
