OCI Datatype Mapping and Manipulation Functions, 116 of 135
Clears or nullifies a given REF.
void OCIRefClear ( OCIEnv *env, OCIRef *ref );
The OCI environment handle initialized in object mode.
REF to clear.
A REF
is considered to be a null REF
if it no longer points to an object. Logically, a null REF
is a dangling REF
.
Note that a null REF
is still a valid SQL value and is not SQL NULL
. It can be used as a valid non-null constant REF value for a NOT
NULL
column or attribute of a row in a table.
If a null pointer value is passed as a REF
, then this function is non-operational.
