User-defined functions are routines that accept parameters, perform an action, and return the result as a single scalar value or a result set.
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,...

For common language runtime (CLR) functions, the Database Engine relies on the author of the function to mark the function as deterministic or not using the SqlFunction custom attribute. Precision A user-defined function is said to be precise if it does not involve any floating point ...

User-defined functions that return scalar values can be invoked in CHECK constraints if the argument values passed to the function reference columns only in the table or constants. Every time the query processor checks the constraint, the query processor calls the function with the argument values ...
