Azure SQL Database Azure SQL Managed Instance 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 act
No more than 90 parameters are allowed (SQLSTATE 54023). It is possible to register a function that has no parameters. In this case, the parentheses must still be coded, with no intervening data types. For example: CREATE FUNCTION WOOFER() ... No two identically-named functions within a...
If RETURNS NULL ON NULL INPUT is specified in a CLR function, it indicates that SQL Server can return NULL when any of the arguments it receives is NULL, without actually invoking the body of the function. If the method of a CLR function specified in <method_specifier> already has a cust...
Specifies that the function might not return the same result each time that the function is invoked with the same input arguments. The function depends on some state values that affect the results. The database manager uses this information during optimization of SQL statements. An example of a ...
Before a stored function can be created, the userSYSmust run a SQL script that is commonly calledDBMSSTDX.SQL. The exact name and location of this script depend on your operating system. To create a function in your own schema, you must have theCREATEPROCEDUREsystem privilege. To create 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 following example function takes a parameter, performs an operation using an SQL function, and returns the result. In this case, it is unnecessary to use delimiter because the function definition contains no internal ; statement delimiters: mysql> CREATE FUNCTION hello (s CHAR(20)) -> RET...
CREATE FUNCTION sqlserver用户定义函数 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程。用户定义函数不能用于执行一组修改全局数据库状态的操作。与系统函数一样，用户定义函数可以从查询中唤醒调用。也可以像存储过程一样，通过 EXECUTE 语句执行 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程...
The compiler does not allow more than 50 nested function calls to prevent stack overflow. Please make sure that functions are called with less nesting. SeeRecursive TVFexample, below. 重要 In the Public Preview, only a limited grammar check will be performed during creation of a tabl...
