Returns Oracle's raw data type of the field.
However, if you want to get field's type, then oci_field_type() will suit you better.
statementA valid OCI statement identifier.
fieldCan be the field's index (1-based) or name.
Note: In PHP versions before 5.0.0 you must use ocicolumntyperaw() instead. This name still can be used, it was left as alias of oci_field_type_raw() for downwards compatability. This, however, is deprecated and not recommended.
