User-defined functions can't call a stored procedure, but can call an extended stored procedure. User-defined functions can't make use of dynamic SQL or temp tables. Table variables are allowed. SETstatements a
Creates a user-defined function (UDF), which is a Transact-SQL or common language runtime (CLR) routine. A user-defined function accepts parameters, performs an action such as a complex calculation, and returns the result of that action as a value. The return value can either be a scalar...
The CREATE FUNCTION (SQL scalar, table, or row) statement is used to define a user-defined SQL scalar, table, or row function. A scalar function returns a single value each time it is invoked, and is generally valid wherever an SQL expression is valid. A table function can be used in...
Creating a CLR function in SQL Server involves the following steps: Define the function as a static method of a class in a language supported by the .NET Framework. For more information about how to program functions in the common language runtime, see CLR user-defined functions. Then, compi...
A function can have an arbitrary number of parameters. There are a few restrictions: The name of a function must be unique among user defined and system functions. Recursive functions are not allowed. All variables used by a function must be specified in its parameter list....
function-name Names the user-defined function. The combination of name, schema name, the number of parameters, and the data type of each parameter (without regard for any length, precision, scale, or CCSID attributes of the data type) must not identify a user-defined function that exists at...
The return value can either be a scalar (single) value or a table. Use this statement to create a reusable routine that can be used in these ways: In Transact-SQL statements such as SELECT In applications that call the function In the definition of another user-defined function To ...
We'll review three types of user-defined functions. For more details of the different functions, review theT-SQL reference documentation. Inline table-valued functions Inline table-valued functions (TVF) are the simplest function created based on a SELECT statement, and they're the preferred...
