If the function specifies a user-defined type, requires EXECUTE permission on the type.Scalar function examplesScalar function (scalar UDF)The following example creates a multi-statement scalar function (scalar UDF) in the AdventureWorks2022 database. The function takes one i...
You can also alter these user-defined functions. Native compilation improves performance of the evaluation of user-defined functions in Transact-SQL. When you alter a natively compiled, scalar user-defined function, the application remains available while the operation is being run and the new ...

SQL Server has a number of different types of user-defined functions. What are they? 4.3. What is the purpose of UDF in SQL? 4.4. How are stored procedures and user-defined functions different? 4.5. Is it possible to use temporary tables within a user-defined function?
For example, a function that returns the current date or time. SQL Server supports three types of T-SQL UDFs: Scalar Functions, Table-Valued Functions, and Multi-Statement Table-Valued Functions. SQL Server 2019 adds scalar user-defined functions (UDF) inlining. Inlining...
SQL Server uses this attribute to determine the field order for UDTs with multiple values. For an example of a UDT defined with Native serialization, see the Point UDT in Create user-defined types with ADO.NET. UserDefined serialization The UserDefined format...
