User-defined data types (called user-defined types (UDT) in Microsoft Visual Basic, structures in languages like C and C++, and often referred to as records in general scenarios) are groups of related data items declared as one type of information. User-defined data types are very useful ...
Let's proceed to the data members now. First every data member of our UDT must be anautomation compatible type. In the simpler form, as I've conclude, in a UDT we are allowed to use only the types defined in the VARIANT union, if you have checked the code, or whatever VB allows u...
Holds data in a format you define. The Structure statement defines the format. Previous versions of Visual Basic support the user-defined type (UDT). The current version expands the UDT to a structure. A structure is a concatenation of one or more members of various data types. Visual Basic...
User-defined data types are data types based on intrinsic system types given a name by the user, which may then be used in future DDL statements within the database where they were created. It is particularly useful to create a user-defined data type for a unique key that has foreign ...

User-defined types allow for the definition of data types that model the structure and behavior of the data in an application. Input CREATE TYPE t_line AS ( product_line VARCHAR2 ( 30 ) ,product_amount NUMBER ) ; ; Output CREATE
SELECT p.c.m() FROM tb p; This differs from the rules for PL/SQL functions and procedures, where the parentheses are optional for calls that have no arguments. Storage of User-Defined Types Oracle stores and manages data of user-defined types in tables. It automatically and invisibly maps...
