In subject area:Computer Science A User-Defined Type in Computer Science is defined as a type created by the user, which includes a type definition and corresponding type constraints specifying the set of values
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 us to use inside a variant type.
实际运用中,通过合理地利用User Defined Results这个功能可以实现很多在普通界面无法完成的结果查看,这对于不会使用命令流来完成操作的同学来讲非常有好处。 当然如果你会命令流,这些都是基本操作。

The data types in C++ consist of primitive, derived, user-defined, and abstract data types. They help us define the type of data in a variable/ element.
Creating User-Defined TypesIn this section, you will create the UDT definitions using the Visual Studio designer. Perform the following steps:1. Expand the HR.ORCL connection. Right-click User-Defined Types and select New Object Type.2. Enter ADDRESS_OBJ for Type name and under Attributes, ...

CREATE TYPE allows you to create user-defined types in your own schema. CREATE ANY TYPE allows you to create user-defined types in any schema. ALTER ANY TYPE allows you to alter user-defined types in any schema. DROP ANY TYPE allows you to drop named types in any schema. ...
Example: User-defined function Here is an example to add two integers. To perform this task, we have created an user-definedaddNumbers(). #include<stdio.h>intaddNumbers(inta,intb);// function prototypeintmain(){intn1,n2,sum;printf("Enters two numbers: ");scanf("%d %d",&n1,&n2); ...
The type that defines a conversion must be either a source type or a target type of that conversion. A conversion between two user-defined types can be defined in either of the two types. The following example demonstrates how to define an implicit and explicit conversion: C# Copy using ...
