instance. All attributes are assigned a value of NULL
.
STATIC FUNCTION CONSTRUCT RETURN SYS.MGW_NAME_VALUE_T;
These methods construct a new SYS
.MGW_NAME_VALUE_T
instance initialized with the value of a specific type. Each method sets the name
and type
attributes and one of the <>_value
attributes, as shown in the mappings in Table 59-6.
STATIC FUNCTION CONSTRUCT_<> (
name IN VARCHAR2,
