Beginning with SQL Server 2005, you can write user-defined functions in any Microsoft .NET Framework programming language, such as Microsoft Visual Basic .NET or Microsoft Visual C#. There are two types of functions: scalar, which returns a single value, and table-valued, which returns a set...

User-Defined Functions 或 UDF 是資料庫物件,會以程式設計語言密切模擬函式的語意。 如同 C# 中的函式,UDF 可以包含可變數目的輸入參數,並傳回特定類型的值。 UDF 可以傳回純量資料 - 字串、整數等等, 或表格式數據。 讓我們快速查看這兩種類...
SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function)。其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions。 用户定义函数(UDF)在 SQL Server 中发挥重要的作用。用户定义函数可以用于执行复杂的逻辑,...
Like functions in programming languages, SQL Server user-defined functions are routines that accept parameters, perform an action, such as a complex calculation, and return the result of that action as a value. The return value can either be a single scalar value or a result set. ...

User-Defined Functions The Calculator allows you to enter your own set of constants and to define your own functions through the Con and Fun keys shown inFigure 8-10. Figure 8-10 User-defined Function Keys Each of these keys has a menu associated with it, which you display by pressing ME...
CLR languages, and then registered with SQL Server. A user-defined type can be used to define the type of a column in a table, or a variable or routine parameter in the Transact-SQL language. An instance of a user-defined type can be a column in a table, a variable in a batch, ...
