Supplying a value in a sql server 2005 system data type , as long as the user - defined type supports implicit or explicit conversion from that type 提供sql server 2005系统数据类型的值,条件是该用户定义类型支持该类型的隐式转换或显式转换。
A binary value can also be supplied without performing explicit conversion , because all user - defined types are implicitly convertible from binary 由于所有用户定义的类型可以从二进制值进行隐式转换,因此还可以在不执行显式转换的情况下提供二进制值。
Explicit conversions , in which you use casting to convert a value , such as a local variable , a column , or another expression , from one data type to another 显式转换,在该转换中使用转换将值(如局部变量、列或其他表达式)从一种数据类型转换为另一种数据类型。
Generics are useful because they provide stronger compile - time type checking , require fewer explicit conversions between data types , and reduce the need for boxing operations and run - time type checks 泛型相当有用,因为他们提供强制的编译时类型检查,要求更少的数据类型之间的显式转换,并减少装箱拆箱的操作和运行时类型检查。
The first two chapters are focused on the said - ball and wang - ball curves , including their definitions , properties and explicit conversion formulas to the bezier representation , the author also points out that the said - ball basis is ntp 前两章内容包括said - ball基函数和wang - ball基函数的定义、性质、升降阶以及与b zier曲线的互化,同时指出said - ball基函数的规范化全正性。
